Question

我正在尝试将图像发送到我的WCF，当我这样做时，我得到了。

远程服务器返回了意外响应：（400）Bad Request。

其他所有工作都可以发送到WCF并且图像不是那么大~90kb。我发现了很多线程，但没有任何帮助我。我试图增加大小限制，但这不起作用。

的web.config

maxReceivedMessageSize属性需要存在于服务边界，服务和使用者的两侧。因此，您需要将绑定元素添加到客户端配置中。

<强>更新

您需要在服务app.config中包含web.config的绑定：

<bindings>
  <wsHttpBinding>
    <binding name="WSHttpBinding_IService" closeTimeout="00:01:00"
    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
    bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
    maxBufferPoolSize="2000000" maxReceivedMessageSize="2000000"
    messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
    allowCookies="false">
      <readerQuotas maxDepth="2000000" maxStringContentLength="2000000" maxArrayLength="2000000"
      maxBytesPerRead="2000000" maxNameTableCharCount="2000000" />
      <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" establishSecurityContext="true" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

然后，您可以使用端点bindingConfiguration属性在app.config中的服务端点中引用此绑定元素，在这种情况下，您可以将其设置为与{{1}的名称相同的值} element，这是“WSHttpBinding_IService”。

例如

wsHttpBinding
