the content type 'application/json; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'
提问by carlosfigueira
When using firebug, I got this wired error "NetworkError: 415 Cannot process the ...xt/xml; charset=utf-8'. - http://localhost:59899/wsccc1/wscccService.svc/RunTts" in my asp.net mvc 4 project.
使用 firebug 时，我http://localhost:59899/wsccc1/wscccService.svc/RunTts在我的 asp.net mvc 4 项目中收到此有线错误“NetworkError: 415 无法处理 ...xt/xml; charset=utf-8' .-”。
The code:
编码：
<script lang="javascript" type="text/javascript">
function ttsFunction() {
serviceUrl = "http://localhost:59899/wsccc1/wscccService.svc/RunTts";
var data = new Object();
data.text = $('#speak').val();
var jsonString = JSON.stringify(data);
$.ajax({
type: 'POST',
url: serviceUrl,
data: jsonString,
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function() { alert('ok')},
error: function (xhr,status,error) {
console.log("Status: " + status);
console.log("Error: " + error);
console.log("xhr: " + xhr.readyState);
},
statusCode: {
404: function() {
console.log('page not found');
}
}
});
}
</script>
The service code:
服务代码：
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class wservice:Iwservice
{
public string RunTts(string value)
{
return value.ToUpper();
}
}
The interface is:
界面是：
namespace service
{
[ServiceContract]
public interface Iwservice
{
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "RunTts")]
string RunTts(string text);
}
}
And web config, I used file-less in WCF.:
和 web 配置，我在 WCF 中使用了无文件。：
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.5"/>
<httpRuntime targetFramework="4.5"/>
</system.web>
<system.serviceModel>
<serviceHostingEnvironment >
<serviceActivations>
<add factory="System.ServiceModel.Activation.ServiceHostFactory"
relativeAddress="./wsccc1/wscccService.svc"
service="service.wservice"/>
</serviceActivations>
</serviceHostingEnvironment>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>

You need to use the WebServiceHostFactory, instead of the regular ServiceHostFactoryin your code. That will configure the endpoint with the appropriate binding (webHttpBinding) and behavior (webHttp) to honor the [WebInvoke]attribute.
您需要在代码中使用WebServiceHostFactory, 而不是常规ServiceHostFactory。这将使用适当的绑定 ( webHttpBinding) 和行为 ( webHttp)配置端点以支持该[WebInvoke]属性。
<serviceHostingEnvironment >
<serviceActivations>
<add factory="System.ServiceModel.Activation.WebServiceHostFactory"
relativeAddress="./wsccc1/wscccService.svc"
service="service.wservice"/>
</serviceActivations>
</serviceHostingEnvironment>

Go to your web.config endpoint tag and check if bindingConfigurationis properly present or not and also make sure the address is spelled correctly.
转到您的 web.config 端点标记并检查是否bindingConfiguration正确存在，并确保地址拼写正确。
<endpoint address="/YourName".../>
