c# - WCF method call from browser returns 400 bad request -

i using asp.net 3.5 c# in visual studio 2008. naive wcf. have created sample wcf application , run on asp.net development server in visual studio. calling getdata() method i.e. auto-generated while creating applicaiton , getting 400 bad request. have tried lot result frustrating.

my interface iservice1.cs below :

using system; using system.collections.generic; using system.linq; using system.runtime.serialization; using system.servicemodel; using system.text; using system.servicemodel.web; using system.servicemodel.activation;  namespace wcfservice1 {     // note: if change interface name "iservice1" here, must update reference "iservice1" in web.config.     [servicecontract]     public interface iservice1     {          [operationcontract]         [webinvoke(requestformat=webmessageformat.json,responseformat=webmessageformat.json,method="get",uritemplate="/getdata/{}")]         string getdata(int value);          [operationcontract]         compositetype getdatausingdatacontract(compositetype composite);          // todo: add service operations here     }       // use data contract illustrated in sample below add composite types service operations.     [datacontract]     public class compositetype     {         bool boolvalue = true;         string stringvalue = "hello ";          [datamember]         public bool boolvalue         {             { return boolvalue; }             set { boolvalue = value; }         }          [datamember]         public string stringvalue         {             { return stringvalue; }             set { stringvalue = value; }         }     } } 

and class service1.svc.cs file below :

using system; using system.collections.generic; using system.linq; using system.runtime.serialization; using system.servicemodel; using system.text;  namespace wcfservice1 {     // note: if change class name "service1" here, must update reference "service1" in web.config , in associated .svc file.     public class service1 : iservice1     {         public string getdata(int value)         {             return string.format("you entered: {0}", value);         }          public compositetype getdatausingdatacontract(compositetype composite)         {             if (composite.boolvalue)             {                 composite.stringvalue += "suffix";             }             return composite;         }     } }

the url below :

http://localhost:51671/service1.svc/getdata/1 

can help?

there 4 things wrong:

first, should using webhttpbinding instead of wshttpbinding. wshttpbinding soap services - not rest services.

second, need add endpoint behaviour.

so, endpoint this:

<endpoint address="" binding="webhttpbinding" contract="wcfservice1.iservice1" behaviorconfiguration="webbehavior"> 

and in behaviors section should have

  <endpointbehaviors>     <behavior name="webbehavior">       <webhttp />     </behavior>   </endpointbehaviors> 

third, uri template should be

uritemplate="/getdata/{value}" 

rather than

uritemplate="/getdata/{}" 

and finally, parameters use in uri template must of type string, so

string getdata(string value); 

rather than

string getdata(int value); 

inside service operation have parse string value correct type.

overall, much easier rest asp.net webapi rather wcf rest. if can move .net 4 instead of 3.5 make quicker progress , working supported platform.

also, development should set

<servicedebug includeexceptiondetailinfaults="true"/> 

so can more information on goes wrong. remember set false production though.
