当POST一些数据时WCF错误400错误的请求
问题描述:
我的本地机器中有一个WCF服务,它的作用类似于客户端应用程序和远程数据库之间的“桥梁”。当POST一些数据时WCF错误400错误的请求
WCF服务与实体框架类一起工作,并且在获取数据时工作正常,但在发布任何内容时无法正常工作,并且收到下一条错误消息:“(400)Bad Request”。
这是我的客户端代码:
//Connect to WCF Service
CHS_Local.ServiceFrontalClient proxy = new CHS_Local.ServiceFrontalClient();
//Get a "Client" class wich ClientID == 1
CHS_Local.Client client = proxy.GetClient(1);
//Change some stuff
client.Name = "change someting";
//Send the modified class to service to update the database
proxy.UpdateClient(client);
这是我<system.serviceModel>
标签WCF中的配置文件:
<system.serviceModel>
<services>
<service name="CentralizedHostingService.ServiceFrontal">
<endpoint
address=""
binding="wsHttpBinding"
contract="CentralizedHostingService.IServiceFrontal">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint
address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8732/Design_Time_Addresses/CentralizedHostingService/Service1/" />
</baseAddresses>
</host>
</service>

<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="True" />
<serviceDebug includeExceptionDetailInFaults="False" />
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
和我的客户端应用程序app.config
:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IServiceFrontal" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

<security mode="Message">
<transport clientCredentialType="Windows"

<message clientCredentialType="Windows"

algorithmSuite="Default" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint
address="http://localhost:8732/Design_Time_Addresses/CentralizedHostingService/Service1/"
binding="wsHttpBinding"
bindingConfiguration="WSHttpBinding_IServiceFrontal"
contract="CHS_Local.IServiceFrontal" name="WSHttpBinding_IServiceFrontal">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
</client>
</system.serviceModel>
服务接口:
[OperationContract]
Client GetClient(int clientID);
[OperationContract]
void UpdateClient(Client editedClient);
在第一个例子中,虽然问题存在于请愿的权重,但我看到使用Fiddler字节发送请求只有115.903字节(〜0.11MB)。 有什么想法?
正如你所看到的是一个简单的例子,但没有工作:(
感谢您帮助!:)
答
您必须设置maxReceivedMessageSize
和readerQuotas
(如果需要)在服务发布数据时来自客户。您的客户端配置已修改maxReceivedMessageSize
,它用于从服务获取数据,但是当您向服务发送大量数据时,您还必须修改其配置。
喜欢的东西:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="myBinding" maxReceivedMessageSize="500000" />
</wsHttpBinding>
</bindings>
<services>
<service name="CentralizedHostingService.ServiceFrontal">
<endpoint bindingConfiguration="myBinding" ... />
...
</service>
</services>
...
</system.serviceModel>
