Cannot Upload A File To A Webservice And Get The Response In Json Format

Aug 10, 2010

I have a simple webservice that I would like to upload a file to. The problem is that I need the response in json.

Form my experience in order to get a response in Json my request has to have a content-type of 'application/json'. But ofcourse this cannot be the case with a file upload since the content type will have to be 'multipart/form-data'.

In my Json i want to return a value showing whether successful and a filename.

JSON Webservice Response Compression In IIS 7?

Mar 20, 2010

I have trouble with JSON response compression. I look to response headers after uploading website to production server (Windows 2008, IIS 7) and found uncompressed response. Turning on "Enabled static compression" and ""Enable dynamic compression" in IIS control panel does not effect. ASPX pages was responsed gzipped, but webservice response uncompressed.

I looked to google, but no answer found about this trouble. Also, I try this [URL] way (and adding to web.config this module) - but this source is excellent working at development machine with ASP.NET development server (and have seven times response size reduced) and totally ignored at IIS7.

How I can apply gzip compression to json responses from my webservice?

Jun 17, 2010

I have a webservice that sends the response back in XML format.I'm able to connect and call the webservice adding an external web reference to the Visual Studio project.Then in my code behind:As New servicename_addedLabel1.Text = servicename_added.Functionexposed(param1, param2, etc)With that code I can get the response in a large label and unstructured data.

WCF / ASMX :: Uploading File To Webservice Method Fails - Request Format Is Invalid?

Apr 27, 2010

have a working ASP.NET 3.5 webservice that accepts standard POST requests using an encoding type of application/x-www-form-urlencoded. I then added a method which needs to accept an uploaded file. We change the encoding type of the request to multipart/form-data so that we can get the file data and now we receive the following error:System.InvalidOperationException: Request format is invalid: multipart/form-data

AJAX :: How To Upload A File From Server To Client Without Attaching It To The Response

Mar 22, 2011

Basically I have to generate a rather large XPS document serverside and send this back to the client.

The issue I have whilst trying to do this is because the XPS document needs to be created on a STA thread, so either the response is sent back before the async operation is complete (in which case I can't attach the file using the transferfile method) OR I have to wait until the Async thread has completed and then I can send the file using the transferfile method (but this leaves the current page locked out for quite a while).

AJAX :: How To Format Text In C# Into Proper JSON Format

Nov 30, 2010

I'm using jquery autocomplete to call a .aspx page which returns some matching words.

The jQuery stuff relies on a JSON feed to work. Currently, in my C# I'm formatting the output as a string, which ouputs something like this:

{ query:'aa','aardvark','aardvarks']}

I was hoping that because the string is formatted in the JSON format, that would be good enough for the Javascript to process but it appears not.

how to format this text in C# into proper JSON format which JavaScript can deal with properly?

I have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query.

"myData": {
"randomNumber": "129",
"Application": "MyMapApp",

Webservice Won't Accept JSON Requests?

Apr 13, 2010

The main issue is that I cannot run a webservice that accepts requests in JSON format. I keep getting a 500 Server error stating that the "request format is invalid." My ASP.NET AJAX extensions are installed. My server is running Plesk Control Panel 8.6 which is undoubtedly causing these problems.

The default handler for this specified extension is shown in the web.config like so:

For my applications webservice to handle JSON it needs to have this reference:

<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

Plesk is not allowing the request to be handled properly. I need to know the correct http directive(s) to put into the web.config to properly handle JSON webservices.

Call External Json Webservice From C#?

Jan 15, 2010

I need to make a call to a json webservice from C# Asp.net. The service returns a json object and the json data that the webservice wants look like this:

"data" : "my data"

This is what I've come up with but I can't understand how I add the data to my request and send it and then parse the json data that I get back.

string data = "test";
Uri address = new Uri("http://localhost/Service.svc/json");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
string postData = "{"data":"" + data + ""}";

How can I add my json data to my request and then parse the response?

JQuery UI Autocomplete WebService Source Returning JSON?

Nov 29, 2010

I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.

There are several issues:

1) The autocomplete function is not firing
2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception
3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return.
4) I am not at all certain that this code will accept JSON data that comes back from the service

How To Send A Single Quote As Value In JSON Webservice Call

Feb 17, 2011

I'm trying to make a call to a JSON ASP.NET web service with .NET.

It is ok when I send " { county : 'whatever' } ", but I get a 500 Internal Server error if I try for example " { county : 'It's ok' } ".

[Code]....

I've found some posts with examples but I cannot make it work:

" { county : "whatever" } " and " { "county" : "whatever" } " also works.

But either of " { county : "It's ok" } ", " { county : "It's ok" } " or any other combination that contains a single quote in the variable work.

How can I send a single quote inside a JSON call?

JQuery :: Compute JSON In JTemplate In Webservice Manually?

Mar 31, 2011

I have a webservice which retrieves data from another external service. The data is already in JSON Format. So I retrieve it and set it to the return value (type: string) of my webservice. But according to firebug the webservice then encapsulates the provided JSON-Data with a backslash, e.g. it returns:

[Code]....

instead of

[Code]....

But the JSON provided by the external service is correct. So how could I provide the correct string to jTemplate from my Webservice?

How To Increase 2MB Limit On AJAX JSON Response

Dec 20, 2010

I am having problems making an AJAX call when the response is over 2MB. Anything with a response under 2MB works fine. When the response is over 2MB, my "success" method never gets called. My application is ASP.NET MVC2.

I am making the call using the jQuery AJAX call:
$.ajax({ type: "post", data: ajaxData, url: ajaxUrl, success: updateItems, cache: false });

In my controller, I am using the Json() action result method:
public ActionResult GetItems(....) { ...
return Json(packet); }

When I watch the call in Fiddler it comes back with a HTTP 500 response. I tried setting the maxJsonLength in the Web.config file as shown here, but that doesn't seem to make any difference. How to allow a response over 2MB?
