I am facing an issue while calling a web request thru my code. I have searched a lot on number of sites but did not get any solution.
Here is the code which I am using:
[Code]....
I have a .Net Webservice(2.0 framework) and I am trying to call this service from SQL
server 2005 using CLR.
I have created assamblies on server and trying to call the we service through CLR, but I'm getting below error:
"Exception:
Server was unable to process request. ---> Invalid URI: The URI is empty."
I have a webservice which works 100% fine on my developer machine. Where Web Service is installed on LOCALHOST on my developer machine,Then i went to my servers, I installed webservice on one server and map it with the server where the website is hosted, Then i tried accessing this service using BROWSER from my web server, it worked fine, That means the mapping was done perfect.Then i run my program on web server (website). It worked fine on page1, then on page2, but when i did the same and call same function on page3, It popped me any error of
View 4 RepliesI am trying to call a webservice and i am receiving the following error
Server was unable to process request -- > object reference not set to an instance of object .
Steps done for calling the webservice
1) created a wrapper class using wsdl.exe tool
syntax :- wsdl.exe /l:vb <url.asmx?wsdl>
<url.asmx?wsdl> is the url of the webservice to be called.
2) Imports <webservicenamespace>
[Code]....
3) while checking the trace Its occuring while invoking the webservice function
object[] results = this.Invoke(<webservicefunction(parameters)>)
I want to use web service for periodic update request to server. It will use get & Post method.
Using post request I will use follwing URL. I will get this from some device.
[URL]
If request will come like this ... as URL contains 'update' so it should update & after parsing URL, will send reply in the form of URL.
I'm getting an exception when trying to access an .asmx webservice within a MVC site. I've tried numerous things like updating the web reference within the console application and building another quick app to test, but can't get passed this issue. If I pull the URL out of the svc variable, I can browse to it directly.

The exception was coming out of the Web Service itself. There were some global variables not being initialized directly through the .asmx call that were being initialized by the application itself.
Some simple checks on variables within the Web Service and setting what needs to be set have fixed up the issue.
Hoping someone can point me to a solution, haven't been able to find one yet.
I'm using the standard way for send HttpWebRequest
[Code]....
As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.
A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a webservice, it has few webmethods. when i create a client proxy and invoke the methods to check its response, i am getting this error. Can someone tell me what things can i check to know the cause of this? The error is not saying much hence blocked on this.
View 1 RepliesI have created a web service that interacts with my DAL. It has the usual kind of methods, create, retrieve, update and delete. I have published this web service to our live Windows Server and I can see the web serice URL. The web service works on a few method calls but does not work specifically for one object. I am getting the following error: Fault Exception was unhandled by user code. "Server was unable to process request. ---> Data is Null. This method or property cannot be called on Null values."
To summarise: Web service is live, I can see it in my browser. Some method calls work. One specific one does not. I have verified that the method works (it is just calling a SQL stored proc that does return data).
I have a dynamic catalogue, where customers select products they are interested in. The manager of the company I am doing this for would like to be able to create an up to date offline catalogue at any given time, to send out to customers who dont have an internet connection. So far its going really well. I am using Server.Execute to get the content for each page, then putting it in static html pages and changing the dynamic links to static html links (ie changing all aspx links to htm). I am able to output all the pages for about us, contact us, home, and the entire catalogue. However, one of the stylesheets which is included in the page based on the URL (if the page is in the administration section then it is not included, otherwise it is) is not being included in the pages when it should be. I have tried outputting the URL but it just returns the URL of the calling page, not the page being called.
View 1 RepliesI'm looking for a good way to prevent the scenario of the page calling itself repeatedly.
I have a page, that to be rendered needs to make an HTTP request to an RSS feed. If the URL to that RSS feed happens to be the current page, it will fire off a request to itself. The new request would start off another request to the page, which would start another request... This continues until the site grinds to a halt when all available connections are busy in this recursive loop.
A few notes:
The URL to the RSS is entered by the user.
This is a page in a CMS, the URL of the page could be almost anything and could change after the RSS URL is entered.
In this case, the user entered a URL to a remote server that lead to a redirect back to the page.
A few ideas:
I could just deny all requests from the localhost IP before rendering.
Before sending the request, I could track in a common location which requests are active and not even send it if it's already in the middle of another request to the same address.
Maybe add a custom user-agent to the request header and deny the request if that user agent is seen?
function DatalistFunction(argumentid) {
set_minimum_points_for_session = value;
SetSession(set_minimum_points_for_session);
Redeem(argumentid);
}
this is my code which i am calling on link button onclientclick event.
sometimes what happens is redeem function gets called first and then setsession function gets called. do i need to put some delay or something between the 2 functions, so that they run everytime in their own order
We're trying to implement functionality that intercepts, inspects, and alters if needed data in the Request.QueryString and Request.Form collections.
Since Request.QueryString and Request.Form are readonly, is it possible to use a HttpModule to do this without Reflection or Response.Redirect?
We're thinking that we can construct a new HttpRequest, and replace the original one. Would there be any implications in doing this?
I know mocking this object is impossible without using HttpRequestWrapper, but wasn't sure whether ASP.NET sets other things beyond the constructor.
Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.
This is a input
<input type="image" src="<%=Url.Content("~/images/shopping-cart.jpg")%>" alt="shopping cart" id="btnshoppingCart" name="btnshoppingCart" value="shoppingCart" />
when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.
When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this
<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>
The version of internet explorer is 8.0 and firefox is 3.6.6
I there a way to know if a request is a soap request on AuthenticateRequest event for HttpApplication? Checking ServerVariables["HTTP_SOAPACTION"] seems to not be working all the time.
public void Init(HttpApplication context) {
context.AuthenticateRequest += new EventHandler(AuthenticateRequest);
}
protected void AuthenticateRequest(object sender, EventArgs e) {
app = sender as HttpApplication;
if (app.Request.ServerVariables["HTTP_SOAPACTION"] != null) {
// a few requests do not enter here, but my webservice class still executing
// ...
}
}
I have disabled HTTP POST and HTTP GET for webservices in my web.config file.
<webServices>
<protocols>
<remove name="HttpGet" />
<remove name="HttpPost" />
<add name="AnyHttpSoap" />
</protocols>
</webServices>
Looking at ContentType for soap+xml only partially solves my problem. For example,
Cache-Control: no-cache
Connection: Keep-Alive
Content-Length: 1131
Content-Type: text/xml
Accept: */*
Accept-Encoding: gzip, deflate
Accept-Language: ro
Host: localhost
mymethod: urn:[URL]
Some clients instead of having the standard header SOAPAction: [URL], have someting like in example above. "mymethod" represents the method in my web service class with [WebMethod] attribute on it and [URL] is the namespace of the webservice. Still the service works perfectly normal. The consumers use different frameworks (NuSOAP from PHP, .NET, Java, etc).
I develop an asmx web service (i.e. ASP.NET 2.0). There's a piece of code that may read the contents of the HTTP request (via HttpContext.Current.Request.InputStream) while processing it. I realise that InputStream may only be read once for a request, and I make sure I never try to read it more than once.
The problem seems to be that if InputStream happens to be read during the early stages of the application's lifecycle (e.g. after pskill w3wp, during Application_Start), the HTTP request fails with a HTTP 400 - Bad Request error, with no explanation given, no exception thrown and no entry in the httperr log. If it is read later (e.g. within the web method itself), requests run fine whether InputStream is read or not. Application_Start runs fine if InputStream isn't read.
Is this some sort of ASP.NET bug? IIS bug? Or am I doing something wrong by daring to read InputStream? And if so, is there another way to get a look at the "raw" contents of the request without disturbing the inner workings of IIS/ASP.NET? In short, adding this code within Application_Start is enough to reproduce this error: using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))reader.ReadToEnd();
I want to component to upload large filesP.How can I bypass request size и request processing time restrictions?
View 4 Repliestried so many different things but havent got past this seemingly trivial problem. I created a WCF service application from visual studio 2010 WCF templates. it generated the IService.cs and Service1.svc files and generated the web.config
i created a website in IIS 7 on windows 2008, and pointed it to the app folder. when i go to [URL] via web browser, i get a message indicating service is running and suggests using svcutil etc etc., but when i go to [URL] the web browser says 400 bad request. this is without changing anything from what VS generated. the operation contract looks like
[Code]....
Update: forgot to mention i even tried decorating the operation with WebGet attribute with UriTemplate parameter, without luck.

I am trying to use curl to access 3rd party webservice, I used the following code which works well if I try it on my own linux server, the data is being sent ok, but the IIS on the 3rd party server returns an error.
$longdata is a long string of data, maybe over 1000 characters long the 3rd party has many working clients with various implementations so the problem is on my side. what do I need to add to the request in order to get this through ?
<?php
$c = curl_init();
// curl_setopt($c, CURLOPT_HTTPHEADER, array('Expect:'));
curl_setopt($c, CURLOPT_URL, 'http://XXX.com/test/index.asmx');
curl_setopt($c, CURLOPT_POST, 1);
curl_setopt($c, CURLOPT_HEADER, 1);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$post = array('param1' => 'XXXX', "param2" => "Y", "Param3" => $long_data);
curl_setopt($c, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($c);
echo $response;

I'm consuming an external web service (yahoo adverts), and what I need is capture the SOAP XML request I'm sending and response I'm getting.
I tried using Fiddler, but wasn't able to capture the request. how to do this?
I created a WCF. The web.config is as follows,
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.web>
<compilation debug="true" />
</system.web>
<system.serviceModel>
</system.serviceModel>
<system.webServer>
<directoryBrowse enabled="true" />
</system.webServer>
</configuration>
The following can be seen in the service.svc file,
class AppServiceHostFactory : ServiceHostFactory
{
protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
return new WebServiceHost2(serviceType, true, baseAddresses);
}
}
This is the method in the service.svc.cs,
[WebHelp(Comment="Sample description for GetData")]
[WebGet(UriTemplate="/GetData/param1/{i}/param2/{s}")]
[OperationContract]
public SampleResponseBody GetData(string i, string s)
{
// TODO: Change the sample implementation here
// if (i < 0) throw new WebProtocolException(HttpStatusCode.BadRequest, "param1 cannot be negative", null);
return new SampleResponseBody()
{
Value = String.Format("Sample GetData response: '{0}', '{1}'", i, s)
};
}
The following is the webservice url. It returns data if it's run through the asp.net engine but throws bad request when run from IIS. I added the following entry in the web.config but no use. it still fails.
<httpRuntime maxRequestLength="1500000" executionTimeout="180"/>
