状态码413(RequestEntityTooLarge)/状态码415(UnsupportedMediaType)。 WCF以编程方式

标签: c# wcf svcutil.exe

我正在通过SvcUtil.exe生成类文件来以编程方式调用WCF Web服务。

一切正常,但是当我尝试发送图像(实际上是一个大小超过200KB的文件)时,出现此错误。

我知道我需要将maxReceivedMessageSizemaxBufferPoolSize增加到最大,才能将大文件发送到WCF服务。因此,执行此操作的XML版本如下所示:

<binding name="SampleBinding" allowCookies="true" messageEncoding="Mtom" maxReceivedMessageSize="20000000" maxBufferSize="20000000" maxBufferPoolSize="20000000">
  <readerQuotas maxDepth="32" maxArrayLength="200000000" maxStringContentLength="200000000"/>
  <security mode="None">
    <transport proxyCredentialType="Basic"/>
  </security>
</binding>

在这个应用程序中,由于我使用的是SvcUtil生成的类文件,因此需要以编程方式调用WCF服务方法。

我做到了

var binding = new BasicHttpBinding();
binding.MaxReceivedMessageSize = binding.MaxBufferPoolSize = long.MaxValue;
binding.AllowCookies = true;
binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas();
binding.ReaderQuotas.MaxArrayLength = binding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;
binding.ReaderQuotas.MaxStringContentLength = binding.ReaderQuotas.MaxNameTableCharCount = int.MaxValue;
binding.ReaderQuotas.MaxDepth = int.MaxValue;

webAPI = new WebAPIClient(binding, new EndpointAddress(soapUrl));

XML版本确实运行良好,但是C#版本由于以下堆栈跟踪而失败:

已联系我使用自定义绑定。下面是我的自定义绑定代码:

CustomBinding binding = new CustomBinding()
{
    Name = "SampleBinding",
    ReceiveTimeout = new TimeSpan(0, 0, 10, 0, 0),
    SendTimeout = new TimeSpan(0, 0, 10, 0, 0),
};
var element1 = new TextMessageEncodingBindingElement()
{
    ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas()
    {
        MaxDepth = 2147483647,
        MaxStringContentLength = 2147483647,
        MaxArrayLength = 2147483647,
        MaxBytesPerRead = 2147483647,
        MaxNameTableCharCount = 2147483647
    }
};
var element2 = new HttpTransportBindingElement()
{
    ManualAddressing = false,
    MaxReceivedMessageSize = 2147483647,
    AllowCookies = false,
    AuthenticationScheme = System.Net.AuthenticationSchemes.None,
    BypassProxyOnLocal = false,
    MaxBufferSize = 2147483647,
    ProxyAuthenticationScheme = System.Net.AuthenticationSchemes.None,
    TransferMode = TransferMode.Buffered,
    UseDefaultWebProxy = true
};
var element3 = new TextMessageEncodingBindingElement(MessageVersion.Soap12WSAddressing10, System.Text.Encoding.UTF8);

binding.Elements.Add(element1);
binding.Elements.Add(element2);
binding.Elements.Add(element3);

webAPI = new WebAPIClient(binding, new EndpointAddress(soapUrl));
  

处理Web请求时出错:状态码   415(UnsupportedMediaType):无法处理消息,因为   内容类型为'application / soap + xml; charset = utf-8'不是   预期的类型为'text / xml; charset = utf-8'。

我不知道怎么了。你能帮我吗?

我刚刚找到了一个答案,并在此处向可能与我有相同问题的未来用户发布了答案:

我的客户电话

webAPI = new WebAPIClient(new BasicHttpBinding(), new EndpointAddress(_urlString);

WCF服务的服务器配置

<endpoint address="url/WebAPI.svc" binding="basicHttpBinding" contract="MyContract.IWebAPI" />

<bindings>
  <basicHttpBinding>
    <binding maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text">
      <readerQuotas maxDepth="2000000" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
</bindings>

如您所见,在这里我没有提及绑定配置的任何名称,它就像一个超级按钮。
