當POST一些數據時WCF錯誤400錯誤的請求

Question

我的本地機器中有一個WCF服務，它的作用類似於客戶端應用程序和遠程數據庫之間的「橋樑」。

WCF服務與實體框架類一起工作，並且在獲取數據時工作正常，但在發佈任何內容時無法正常工作，並且收到下一條錯誤消息：「（400）Bad Request」。

這是我的客戶端代碼：

//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); 

這是我<system.serviceModel>標籤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> 
    </services> 
    <behaviors> 
    <serviceBehaviors> 
     <behavior> 
      <serviceMetadata httpGetEnabled="True" /> 
     <serviceDebug includeExceptionDetailInFaults="False" /> 
     </behavior> 
    </serviceBehaviors> 
    </behaviors> 
</system.serviceModel> 

和我的客戶端應用程序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" 
       bypassProxyOnLocal="false" transactionFlow="false" 
       hostNameComparisonMode="StrongWildcard" 
       maxBufferPoolSize="524288" maxReceivedMessageSize="5000000" 
       messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" 
       allowCookies="false"> 
       <readerQuotas 
        maxDepth="32" maxStringContentLength="8192" 
        maxArrayLength="16384" maxBytesPerRead="4096" 
        maxNameTableCharCount="16384" /> 
       <reliableSession ordered="true" inactivityTimeout="00:10:00" 
        enabled="false" /> 
       <security mode="Message"> 
        <transport clientCredentialType="Windows" 
           proxyCredentialType="None" realm="" /> 
        <message clientCredentialType="Windows" 
          negotiateServiceCredential="true" 
          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> 

服務接口：

[OperationContract] 
    Client GetClient(int clientID); 

    [OperationContract] 
    void UpdateClient(Client editedClient); 

在第一個例子中，雖然問題存在於請願的權重，但我看到使用Fiddler字節發送請求只有115.903字節（〜0.11MB）。 有什麼想法？

正如你所看到的是一個簡單的例子，但沒有工作:(

感謝您幫助！:)

您必須設置maxReceivedMessageSize和readerQuotas（如果需要）在服務發佈數據時來自客戶。您的客戶端配置已修改maxReceivedMessageSize，它用於從服務獲取數據，但是當您向服務發送大量數據時，您還必須修改其配置。

<system.serviceModel> 
    <bindings> 
    <wsHttpBinding> 
     <binding name="myBinding" maxReceivedMessageSize="500000" /> 
    </wsHttpBinding> 
    </bindings> 
    <services> 
    <service name="CentralizedHostingService.ServiceFrontal"> 
     <endpoint bindingConfiguration="myBinding" ... /> 
     ... 
    </service> 
    </services> 
    ... 
</system.serviceModel>
