Question

我创建了一个WCF服务，该服务将String（Text / Json）作为请求接收，但是问题是它只能接收65536（String.Length）的字符串长度。我在下面尝试通过谷歌搜索（绑定maxReceivedMessageSize =“ 2147483647”），但没有任何变化，它只能接收65536的String.Length大小，仅此而已。我是dotNet和WCF一词的新手，有人可以帮助我向该服务发送大数据（我想向WCF服务发送大约10MB的数据）。

   My Server Config:

   <?xml version="1.0" encoding="utf-8" ?>
    <configuration>
      <system.serviceModel>
        <services>
          <service name="[my-service-name]">
            <endpoint address="http://localhost:8005/MyService"
                  binding="webHttpBinding"
                  contract="[my-service-contract-name]"/>
          </service>
        </services>
        <bindings>
          <basicHttpBinding>

              maxArrayLength="2147483647"
              maxStringContentLength="2147483647"/>
            </binding>
          </basicHttpBinding>
        </bindings>

          <serviceBehaviors>

      <startup> 
          <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
      </startup>
    </configuration>


    My Service:

        [OperationContract]
        [WebInvoke(Method = "POST", UriTemplate = "MyService")]
        void MyService(String input)
        {
            Console.WriteLine("Request data = " + input.Length);
        }



Client Config:    

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />

      <serviceBehaviors>
        <behavior name="behavior-here">

服务的

binding属性设置为webHttpBinding，并且在basicHttpBinding下添加了诸如maxReceivedMessageSize之类的属性。我相信这只是默认的webHttpbinding属性。我建议在您的httpBinding下创建一个绑定，并在新的绑定下进行所有所需的更改maxReceivedMessageSize，并将您的服务与绑定名称绑定在一起，如下所示：

  <basicHttpBinding>
    <binding name="testMessageBinding" maxReceivedMessageSize="30000000" openTimeout="00:00:02" receiveTimeout="00:00:02" sendTimeout="00:00:02" closeTimeout="00:00:02">
          <readerQuotas maxDepth="32"
          maxArrayLength="2147483647"
          maxStringContentLength="2147483647"/>
    </binding>
  </basicHttpBinding>

In your config, please add
"<dataContractSerializer maxItemsInObjectGraph="2147483647"/>"

Service Config:
<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
      <dataContractSerializer maxItemsInObjectGraph="2147483647" />
    </behavior>
  </serviceBehaviors>
</behaviors>

Client Config:
<behaviors>
  <serviceBehaviors>
    <behavior name="MyServiceBehavior">
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

WCF服务仅接收65536 String.Length大小，不大于
