在尝试创建简单服务以通过遵循一些教程来返回简单JSON字符串时.我在两台不同的计算机上遇到HTTP Statuscode 400错误的请求. 示例教程 带有JSON pt.1和amp;的RESTful WCF服务pt.2- http://www.youtube.com/watch?v=5BbDxB_5CZ8

When trying to create a simple service to return a simple JSON string by following several tutorials. I get stuck on two different machines with a HTTP Statuscode 400 bad request. Example tutorials RESTful WCF Service with JSON pt.1 & pt.2 - http://www.youtube.com/watch?v=5BbDxB_5CZ8

我也有Google，并在这里(StackOverflow)搜索了类似的问题，但没有成功.

I have also Google and searched here (StackOverflow) for similar problem without success.

问题是，当尝试进行健全性检查以浏览到WCF服务并执行该方法时，我收到400错误的请求.通过编译服务并浏览此地址: http://localhost:49510/Service1.svc/GetPerson 就像本教程一样.我尝试寻找解决方案已有3天.感谢您的帮助.

The problem is I get the 400 bad request when trying to do a sanity check to browse to the WCF service and execute the method. By compiling the service and browse this address: http://localhost:49510/Service1.svc/GetPerson Just like the tutorial. I have tried finding a solution for like 3 days. Any help is appreciated.

这就是我的工作.

首先，我创建一个简单的WCF Service应用程序的新项目.我删除默认的Service1.svc并添加一个新的WCF服务，该服务会生成一个新的Service1.svc和一个IService1.cs

First i create a new project a simple WCF Service application. I delete the default Service1.svc and add a new WCF Service, that generate a new Service1.svc and a IService1.cs

这是接口( IService1.cs )的代码

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        [WebInvoke(Method="GET", BodyStyle=WebMessageBodyStyle.Bare, ResponseFormat=WebMessageFormat.Json, RequestFormat=WebMessageFormat.Json, UriTemplate="GetPerson")]
        Person GetPerson();
    }

    [DataContract(Name="Person")]
    public class Person
    {
        [DataMember(Name="name")]
        public string Name { get; set; }
    }
}

这是 Service1.svc

namespace WcfService1
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
    public class Service1 : IService1
    {
        public Person GetPerson()
        {
            return new Person() { Name = "Tobbe" };
        }
    }
}

Web.config保持不变，看起来像这样的 web.config

And the Web.config is untouched and look likes this web.config

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

推荐答案

对于REST WCF，您必须在web.config中进行绑定和端点设置

For REST WCF You have to do binding and endpoint setting in web.config

按照以下说明替换整个web.config，它将起作用

Replace your whole web.config by following and it will work

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <protocolMapping>
      <add scheme="http" binding="webHttpBinding"/>
    </protocolMapping>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>

        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior>
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>  
 </configuration>

您还剩下2件事情

使用webHttpBinding(将默认的http端口映射更改为webHttpBinding)

<system.serviceModel>
    <protocolMapping>
        <add scheme="http" binding="webHttpBinding"/>
    </protocolMapping>
    <behaviors>

<system.serviceModel>

指定webHttp端点行为

<system.serviceModel>
    -----
    </protocolMapping>
    <behaviors>
        <endpointBehaviors>
            <behavior>
                <webHttp />
            </behavior >
        </endpointBehaviors>
    <behaviors>
    ------
<system.serviceModel>
