sending xml inside a soap request with HttpWebRequest

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :ASP.Net
Im trying to send some xml inside a soap request to a webservice using the HttpWebRequest class.  I know this isnt the best way, but my hands are tied by company policy so i have to do it this way.  My webmethod has an input parameter  "SourceXML"  so my soap request has this node<SourceXML></SourceXML>I need to insert the xml in this node but whenver I insert it and try to send it to my web method I get an error "400 bad request"Is this even possible ?  I need to insert the xml as a string literal and read it in the web methodStringBuilder sb = new StringBuilder(_soapEnv); -- soap enevlope template containing the SourceXML node sb.Insert(sb.ToString().IndexOf("</SourceXML>"), the xml I want to insert in the node); sendmessage(url, webmethod, sb.ToString()) -- send the message to the webserviceIf I put plain text in the string builderegsb.Insert(sb.ToString().IndexOf("</SourceXML>"), "this is a test");everything works ok, but as soon as i put some xml in it fails. Am I going about this in the right way ?basically my webmethod will have 2 input parameters, some xml and an object, but I just cant get it to work. Can anyone help ?

Fetch raw XML for SOAP request and response inside WCF client


I've got a basis WinForms test harness that's implementing a WCF client (.NET 3.5) which calls a SOAP web service.  I need to be able to write the HTTP request and response and output the two XML documents so I can load them back into WebBrowser controls on the form.

It looks like the way to accomplish this is to implement a custom IClientMessageInspector and an IEndpointBehavior, apply the behavior to the binding and then do the work of capturing the XML inside AfterReceiveReply and BeforeSendRequest (inside IClientMessageInspector implementation).

So my questions are:

1. This seems like a rather exhaustive process, is there a more straightforward approach to doing this? 

2.  If I am on the right path, does anyone have links to related articles/code samples related to this?

3. In what I have coded so far, I am held up trying to get the behaviorExtension to register properly (inside app.config), it looks as if I must register my classes that implement behavior Extenshions in the GAC in order to make use of them, is this true? 

Thanks in advance for taking time away to help a fellow developer!

DIME: Sending Files, Attachments, and SOAP Messages Via Direct Internet Message Encapsulation


Direct Internet Message Encapsulation (DIME) is a new specification for sending and receiving SOAP messages along with additional attachments, like binary files, XML fragments, and even other SOAP messages, using standard transport protocols like HTTP. In this article, the author explains what DIME is and how it differs from MIME encapsulation. A detailed description of the message format and how it is parsed, as well as working with SOAP and extending it with WSDL, is also included.

Seeing the SOAP request sent from a Web Service Client/Consumer

Hello, I am building a web service consumer in C# in VS2010.  Using the provided WSDL, I need to build appropriate headers and use certificates, SSL (user name & pass), & WS security.  I am getting an error from the webservice side, specifically processing the <wsse:Security> header. Is it possible for me to see the exact request I am sending to the Webservice? I'd like to see the values of the pieces of the header that get put in and such. Is it possible to have human readable serialization of what's being passed in right before the error? Thank You

WCF webservice: HTTP/1.1 400 Bad Request while sending large input

I am connecting to a WCF based webservice. For certain methods, the input contains a list of objects/structures. When the number of items in this list increases beyond a certain number, the service fails with HTTP/1.1 400 Bad Request when I try to test the same using SOAPUI. I tried changing the web.config file with the following changes: <httpRuntime maxRequestLength="2097151" /> <binding name="basicHTTP" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:01:00" sendTimeout="00:01:00" maxReceivedMessageSize="4194304" maxBufferSize="98547" maxBufferPoolSize="258547"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> </binding>   Kangkan

Any way to re-route soap request to different method using soap extensions?

Not sure if this is possible, but is there any way (using soap extensions) to intercept a soap message and re-route it to a different method on the web service host?  I am able to intercept and replace the method name in the xml, but it still goes to the original method.

ASMX to WCF Soap request

I have a .asmx service that I need to convert to WCF. The service receives xml requests via the request input stream,  parses xml and sends clients back a response also in xml. The clients are sending SOAP requests. I have to make this change transparent to the clients. I'm somewhat new to WCF so i'm wondering what would be the best solution. REST looks good but I need to support SOAP. Is it possible to use basicHTTPBinding for my needs?

view soap request message


I am consuming a .net 2.0 webservice from a class library and calling this class from a web page form . When a user inputs and saves the data in the form it will call the class and inturn send the user inputted data over webservice. I want to view the Soap messages like request and response going from my dll to the webservice. I tried fiddler but with no luck. So I created a class mentioned here: http://msdn.microsoft.com/en-us/library/system.web.services.protocols.soapextension(v=VS.90).aspx

and added the in the dll.config file like this and it was also of no help. By the way the end webservice is https not http.

Simple ASP.NET SOAP request to return string



I have a requirement to build a simple ASP.NET web page which sends some parameters to a web service, and then displays the string which was returned.

I'm a complete .NET newby and the only examples I can find seem really really complex.  I just need something mega simple, but which an handle parameters being sent to the web service.  Can anyone point me in the direction of a simple bit of C# which will do this with no frills or fuss?

Any help much appreciated, thanks!

soap:ServerServer was unable to process request.


I had a collaboration site that for several reasons I decided to delete and then create a new one with the same name. In the original version I had created a duplicate DefaultLayout file and renamed the original to DefaultLayouxxxt.aspx.

Now with the completely new version of the site when I try to edit the Default.aspx file using SharePointdesigner I get this error:

soap:ServerServer was unable to process request. ---> The file https://mytestsite/_catalogs/masterpage/DefaultLayouxxxt.aspx does not exist.

How does it know that in a completely non-existent site there once was file that it now wants. But more importantly how do you change the setting so that it wouldn't seek it?




error sending SOAP data to http://localhost/myWCFService/MyWCFService.svc


I am a beginner with WCF services, trying to learn. I created a WCF service where MyWCFServiceInterface has service and data contracts. MyWCFService class implements this interface and has two methods that connect to sqlServer DB to run Sprocs to fetch data. I am hosting this WCFService using IIS6.0. I created a webclient to test the service, which works fine. When I call the service using soap request I get the following error: Could not POST file MyWCFService/MyWCFService.svc on server localhost(415). error sending SOAP data to http://localhost/MyWCFService/MyWCFService.svc


Please check the following wsdl and the soap request and suggest corrections. I greatly appreciate your help. Thanks.

How to properly create SOAP Request that has x509 signed message body and unsigned usernameToken




I'm trying to  create a .NET client that will consume AXIS WS.

Request should be signed (using x509 Signature) and after this usernametoken profile 1.0 should be attached.

Using SOAP-UI I can create Outgoing Security Policy with few steps described below:

1) Define keystore

2) Add WSS Signature entry and mark key identifier type as X509 Certificate or Binary Security Token

3) Add WSS Username entry

The order is important.

I cannot recreate SOAP request that would generate valid response.

I got "The signature or decryption was invalid" most of the time.

Here is valid SOAP Request from SOAP-UI:
