Using Both Post And GetAjax Calls For The Same WebMethod In ASMX Web Service
Jan 20, 2010
I can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:
[code]....
So is it true that you can only use either POST or GET and not both from Ajax?

I have a custom class declared as follows (in vb.net)
<Serializable()> _
Public Class NumInfo
Public n As String
Public f As Integer
Public fc As char()
Public t As Integer
Public tc As char()
Private validFlag As Boolean = True
Public Sub New()
End Sub
I also have public properties(read/write) for all the public variables
End Class
In my service.asmx codebehind class I have a webmethod as follows:
<WebMethod> _
<XmlInclude(GetType(NumInfo))>
Public Function ConvertTo(ByVal info As NumInfo) As String
Return mbc(info)
'mbc is another function defined in my service.asmx "service" class
End Function
The problem is that when I start debugging it to test it, the page that I get does not contain any fields where I could input the values for the public fields of numInfo. How do I initialise the class? There is no "Invoke" button either. All I see are soap details as below:
ConvertTo
Test
The test form is only available for methods with primitive types as parameters. SOAP 1.1 The following is a sample SOAP 1.1 request and response. The placeholders shown need to be replaced with actual values.
POST /BaseConverter/BaseCon.asmx HTTP/1.1
Host: localhost
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://RohitServices.in/ConvertTo"
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ConvertTo xmlns="http://RohitServices.in/">
<info>
<n>string</n>
<f>int</f>
<fc>
<char>char</char>
<char>char</char>
</fc>
What am I doing wrong? For the record I tried replacing char() with string to see if it was the array causing problems but that didn't help either. I'm fairly new to web services. I tried replacing the custom object parameter with a primitive parameter just to check how things worked and it rendered a page with an input field and invoke button. I just can't seem to get it working with custom object.

Recently, I tried to get my Web Service class to inherit from a custom base class that inherits from System.Web.Services.WebMethod instead of the System.Web.Services.WebMethod directly.
However, I've been getting Error 500.
Public Class Service1
Inherits BaseClass
<System.Web.Services.WebMethod()> _
Public Function GetSessionID() As String
GetSessionID = Me.Session.SessionID
End Function
End Class
public class BaseClass
Inherits System.Web.Services.WebService
public property Property1 as string
public property Property2 as string
End Class

My web service uses .Net Framework 2.0. An e-learning application reads and updates an Access database in the web service via Http Post commands. I test the e-learning application and the web service using the version of IIS 7 that came with Windows Vista. I run IIS using localhost in my browser.
All works well. But a friend is having trouble running the same test with my files on her IIS 6 server. So I'm developing a checklist of issues in setting up an IIS 6 server to run a web service. I plan to include all possible causes of problems including permissions, accounts that are needed, etc. Are there resources to which I can go for this checklist?

we need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.So my question, is it better to build a web service or just simply .aspx page?Also is there any best practice documentation on this.

I am trying to post data from vb.net application to web service asmx that is located on server! For posting data from vb.net application I am using this code:
Public Function Post(ByVal url As String, ByVal data As String) As String
Dim vystup As String = Nothing
Try
'Our postvars
Dim buffer As Byte() = Encoding.ASCII.GetBytes(data)
'Initialisation, we use localhost, change if appliable
Dim WebReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
'Our method is post, otherwise the buffer (postvars) would be useless
WebReq.Method = "POST"
'We use form contentType, for the postvars.
WebReq.ContentType = "application/x-www-form-urlencoded"
'The length of the buffer (postvars) is used as contentlength.
WebReq.ContentLength = buffer.Length
'We open a stream for writing the postvars
Dim PostData As Stream = WebReq.GetRequestStream()
'Now we write, and afterwards, we close. Closing is always important!
PostData.Write(buffer, 0, buffer.Length)
PostData.Close()
'Get the response handle, we have no true response yet!
Dim WebResp As HttpWebResponse = DirectCast(WebReq.GetResponse(), HttpWebResponse)
'Let's show some information about the response
Console.WriteLine(WebResp.StatusCode)
Console.WriteLine(WebResp.Server)
'Now, we read the response (the string), and output it.
Dim Answer As Stream = WebResp.GetResponseStream()
Dim _Answer As New StreamReader(Answer)
'Congratulations, you just requested your first POST page, you
'can now start logging into most login forms, with your application
'Or other examples.
vystup = _Answer.ReadToEnd()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Return vystup.Trim() & vbLf
End Function

I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way.
Here's how I return a single function result. How do I return multiple output values?
<asp:ScriptManager ID="ScriptManager1" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />

I have a page that calls on an asmx within the project (for some ajax stuff). Within that asmx I'm calculating a value and returning it to be output to the screen.
However I need to do a recalculation that includes summing this value with a few others. The function that performs the calculation is in a UserControl on the page.
How do I get a reference to the page object so I can use FindControl to get an instance of the user control so I can call that calcuation function?

I need to connect to a WebService provided by someone else. This WS (all https) has three methods that are accessible without having logged on:
login, logoff, getVersion . All other methods require that the login-method has been called before. Nothing special unto this point. However, the docs state that I have to make sure that (quote):
"All method calls between login and logoff are to be carried out by means of the same persistent http-connection (key word: http persistent connections or http connection reuse"
I seem to be unable to figure out how that would work - all WS'es I ever utilized were either taking user/pwd combinations in each method call or the login-method returned something like a SessionID which was then used for each subsequent call to a given method (i.e. passed as a parameter). If I call the login-method and subsequently call any method that requires authentication, the call will fail with an exception telling me that I need to log in first.

I am working on web application in which all of the data I am submitting back to the server is being done on the client side using JQuery AJAX calls to my .NET web services using JSON. This works perfectly to enhance my user experience and greatly reduces post backs, etc.What I am looking for suggestions on is securing the web services being exposed to the client side from being used by anything but my JQuery code on my site. The security hole that I see here is that since the client-side JQuery can access the web services, so could anything.

I have a SOAP web service and I'm trying to figure how to save/log the last 10 requests for each user. Each user is required to send their user/pass in each request, so it's easy to know who the request originated from. With these last 10 requests saved, my goal is to develop some sort of page that will allow them to log-in with their credentials and view the raw request, the actual SOAP message, http header information, and anything relevant that I can think of.
The point is to allow people to troubleshoot their own connection issues instead of having to contact me each time they can't connect, have trouble formatting their request, etc....
My first thought was to store all this information in memory in a hashtable or something, but that may have scalability issues when we have hundreds/thousands of users hitting the web service.
We could use our database to store these requests. Instead of hitting the database each time, I may need to create some "buffer" mechanism that will only update the database after the buffer gets to a certain number of requests. Is there an existing library or mechanism that will do this?
We can't store these requests on the file system on the machine hosting the web service. Since these requests can potentially contain sensitive information, it's a business decision that I'll need to work around. Or maybe there's a better way to achieve what I'm trying to do?

Are web service calls synchronous or asynchronous by default? How is synchronicity determined, by the service or by the client?
I have code similar to the following:
try
{
string result = MakeWebServiceCall_1(); // this is a third party webservice
[code]....
In the above, SetStatus is writing to the same tables that the third party web services read from. If I change the status before both web service calls have completed, it's going to make a big mess and I'm going to get fired. How do I know/ensure that the webservice calls are synchronous?

I've got a web app running with purely web services like these:
Code:
<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=False)> _
Public Function EditService(ByVal toddtype As String _
, ByVal fromddtype As String _
[Code] ....
And I want to log each web service call. I don't want to bother my database with this log - I would prefer to have the web app log to a text file on the web server itself.
How would I open and access a log file like this from a bunch of web services? Does web app still have application startup like events???

In my web app, if user clicks a button, I have to kick off a long running task. I have to keep the user informed about the status of execution of the task from time to time. To accomplish this, I create a thread on button click which makes a synchronous webservice call. The webmethod works on a long running task; while the main thread informs the users about the status of execution.
Currently the webmethod call times out in approximately 90 seconds. I want to increase the timeout to 10 mins. I tried setting <httpRuntime executionTimeout="600"/> along with debug="false"; but in vein. Can anyone tell me what I am missing?

I'm trying to make API calls to a service provider. I've never tackled JSON requests before but I want to give it a go - as they seem less verbose than XML. Could someone be kind enough to give me a simple example here?
My confusion stems from some libraries I've come across. Do I need to add any libraries to my project? Or is it just a matter of creating a string that complies with JSON syntax and send it via a WebRequest?

We have a page that makes a request to a 3'rd party web service. When under heavy load this response time extends significantly, however the 3'rd party reports back that there times for processing remains constant. There timings show that from the time they receive a request to the time they send it back is always around 1.5-2.0 seconds. Now we are experiencing wait times of over 20 seconds. My understanding of ASP.NET is that each request will run on a IIS thread pool thread and make the request to the 3'rd party service return and process. So I don't really understand what could be blocking on our end. Is there something I am missing?? Is there a threshold limit beyond IIS that is blocking?
If I am missing something a physical book recommendation that covers this subject would also be a very welcome addition to any answer.

I have an XML web service where the authentication used is BASIC WINDOWS. Following is my client code to connect to the service.
[Code]....
Now, the issue is that the client is really authenticated only in the first attempt(First time I execute the code in VS). Further attempts succeed even if the code to assign credentials is commented or even after providing wrong user id/ password. I ensured that the server is hit each time(Just to make it clear that it not just because of client side caching).Is this the behavior of Basic authentication/credential cache. I would prefer the client be authenticated each time he hits the server.
