【问题描述】：

我知道这看起来像是重复的问题。

在这里，我想使用 jquery ajax 调用我的 wcf 休息服务，并希望在休息服务中传递以 countryname 作为参数的国家对象。但是每当我使用 html 页面中的 jquery ajax 调用我的休息服务时。但它给了我错误405 method not allowed。我尝试了很多时间来解决它。但我能够解决这个错误。我正在尝试传递数据在 json 对象中。

Iservice.cs：

[OperationContract]
    [WebInvoke(UriTemplate = "/AddCountry", ResponseFormat = WebMessageFormat.Json,RequestFormat=WebMessageFormat.Json)]
    String AddCountry(tableCountry Country);

Service.cs

public string AddCountry(tableCountry Country)
{
    //do Code.
}

Web.config

<system.serviceModel>
        <bindings>
            <webHttpBinding>
                <binding name="webHttpBinding" crossDomainScriptAccessEnabled="true">
                    <security mode="None"/>
                </binding>
            </webHttpBinding>
        </bindings>
        <behaviors>
            <serviceBehaviors>
                <behavior name="">
                    <serviceMetadata httpGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
            </serviceBehaviors>
            <endpointBehaviors>
                <behavior name="webbehaviour">
                    <webHttp/>
                </behavior>
            </endpointBehaviors>
        </behaviors>
        <services>
            <service name="Service">
                <endpoint address="rest" binding="webHttpBinding" contract="IService" bindingConfiguration="webHttpBinding" behaviorConfiguration="webbehaviour"/>
            </service>
        </services>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>  
</system.serviceModel>
<system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="*" />
     </customHeaders>
   </httpProtocol>
   <modules runAllManagedModulesForAllRequests="true"/>
   <directoryBrowse enabled="true"/>
</system.webServer>

Ajax 代码

$("document").ready(function(){    
    var country = {"CountryName":"Iran"};

    $.ajax({
        type: "POST",                   
        url: "http://localhost:2293/ACFRestAjaxParsing/Service.svc/rest/AddCountry",    
        data: JSON.stringify({ Country: country }),                 
        contentType: "application/json; charset=utf-8",
        dataType: "jsonp",
        success: function(data){alert(data);},
        failure: function(errMsg) {
            alert(errMsg);
        }
    });
});

如果有人知道我的这个错误，请帮助我。

提前致谢。

【问题讨论】：

与jsonp 你不应该使用type: "POST",
当我只使用json 然后我得到这个错误No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
尝试另一种方式使用jsonp和type:"get"
但我想将数据发布到服务，那么我该如何使用获取服务。如果您有任何其他方式，请建议。我该如何使用。
什么是跨域请求。

【解决方案1】：

试试这个：

Iservice.cs

[OperationContract]
    [WebInvoke(UriTemplate = "/AddCountry", ResponseFormat = WebMessageFormat.Json,RequestFormat=WebMessageFormat.Json)]
    String AddCountry(tableCountry Country);

public class list_UserContact :  List<tableCountry>
{

}

Service.cs

public string AddCountry(tableCountry Country)
{
    //do Code.
}

Web.config

<system.serviceModel>
        <bindings>
            <webHttpBinding>
                <binding name="webHttpBinding" crossDomainScriptAccessEnabled="true">
                    <security mode="None"/>
                </binding>
            </webHttpBinding>
        </bindings>
        <behaviors>
            <serviceBehaviors>
                <behavior name="">
                    <serviceMetadata httpGetEnabled="true"/>
                    <serviceDebug includeExceptionDetailInFaults="true"/>
                </behavior>
            </serviceBehaviors>
            <endpointBehaviors>
                <behavior name="webbehaviour">
                    <webHttp/>
                </behavior>
            </endpointBehaviors>
        </behaviors>
        <services>
            <service name="Service">
                <endpoint address="rest" binding="webHttpBinding" contract="IService" bindingConfiguration="webHttpBinding" behaviorConfiguration="webbehaviour"/>
            </service>
        </services>
        <serviceHostingEnvironment multipleSiteBindingsEnabled="true"/>  
</system.serviceModel>
<system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="*" />
     </customHeaders>
   </httpProtocol>
   <modules runAllManagedModulesForAllRequests="true"/>
   <directoryBrowse enabled="true"/>
</system.webServer>

Ajax 代码

    function CallWCF() {
        $.ajax({
            type: "POST",
            contentType: "application/json; charset=utf-8",
            url: 'http://yourliveurl/ACFRestAjaxParsing/Service.svc/rest/AddCountry',
            data: '[{"CountryId":2147483647,"CountryName":"String content"}]',
            processData: true,
            dataType: "json",
            success: ServiceSucceeded,
            error: ServiceFailed
        });
    }

    function ServiceFailed(output) {
        Log('Service call failed: ' + output.status + ' ' + output.statusText);
    }

    function ServiceSucceeded(output) {
        var outputValue = output;
        Log("Service call Success: <br/> " + outputValue);
    }

    function Log(displayValueFromService) {
        $("#DisplayOutput").append('<br/>' + displayValueFromService);
    }
</script>

运行：

url:http://localhost:2293/ACFRestAjaxParsing/Service.svc/rest/AddCountry
Header Content :Application/json
Body:Your json data

您的服务将托管在实时 IP 中

Html 文件将托管在 live ip 中
