将大型 xml 上传到 WCF REST 服务 ->400 错误请求 [英] uploading large xml to WCF REST service -> 400 Bad request

问题描述

我一直在尝试搜索此错误，但到目前为止没有运气.

I have been trying to search for this error but no luck so far.

所以我在我的客户端上使用了这个 web.config

So I have a service on my client with this web.config

  <system.serviceModel>
<serviceHostingEnvironment>
  <baseAddressPrefixFilters>
    <add prefix="http://www.mywebsite.com/"/>
  </baseAddressPrefixFilters>
</serviceHostingEnvironment>
<services>
  <service behaviorConfiguration="ServiceBehavior" name="UploadService">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
      contract="IUploadService">
      <identity>
        <dns value="http://www.mywebsites.com/" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ServiceBehavior" maxReceivedMessageSize="4194304">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

在客户端我有这个配置

  <system.serviceModel>
<bindings>
  <wsHttpBinding>
    <binding name="WSHttpBinding_IUploadService" closeTimeout="00:01:00"
      openTimeout="00:01:00" receiveTimeout="00:30:00" sendTimeout="00:30:00"
      bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
      maxBufferPoolSize="524288" maxReceivedMessageSize="4194304"
      messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
      allowCookies="false">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <reliableSession ordered="true" inactivityTimeout="00:30:00"
        enabled="false" />
      <security mode="Message">
        <transport clientCredentialType="Windows" proxyCredentialType="None"
          realm="">
          <extendedProtectionPolicy policyEnforcement="Never" />
        </transport>
        <message clientCredentialType="Windows" negotiateServiceCredential="true"
          algorithmSuite="Default" establishSecurityContext="true" />
      </security>
    </binding>
  </wsHttpBinding>
</bindings>
<client>
  <endpoint address="http://www.mywebsite.com/UploadService.svc"
    binding="basicHttpBinding" bindingConfiguration="" contract="IUploadService"
    name="WSHttpBinding_IUploadService">
    <identity>
      <dns value="http://www.mywebsite.com/" />
    </identity>
  </endpoint>
</client>

我正在上传这样的文件:-

and I am uploading the files like this :-

        using (Stream stream = new FileStream(strFilePath, FileMode.Open, FileAccess.Read))
        {
            try
            {
                using (UploadServiceClient upc = new UploadServiceClient())
                {
                    upc.UploadFile(stream);
                }

            }
            catch (Exception exc)
            {

            }
        }

对于小文件它工作正常，但对于大的 XML 文件，这会因 400 Bad Request 而失败.如何更改这些设置以传输大型 XML 文件?

for small files it works fine, but for large XML files, this failes with 400 Bad Request. What I can do to change these settings to get large XML file to transfer?

感谢您的帮助和时间

更新的客户端 app.config

UPDATED Client app.config

  <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="basicHttpBinding_IUploadService" receiveTimeout="00:20:00"
      bypassProxyOnLocal="true" maxBufferSize="4194304" maxReceivedMessageSize="4194304"
      messageEncoding="Mtom" transferMode="Streamed">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      <security>
        <transport>
          <extendedProtectionPolicy policyEnforcement="Never" />
        </transport>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://www.mywebsite.com/UploadService.svc"
    binding="basicHttpBinding" bindingConfiguration="" contract="IUploadService"
    name="basicHttpBinding_IUploadService">
    <identity>
      <dns value="http://www.mywebsite.com/" />
    </identity>
  </endpoint>
</client>

推荐答案

您应该查看服务是否与客户端具有相同的 maxReceivedMessageSize="4194304" 以及 XML 是否确实小于设置的 4,194,304 字节限制.WCF 默认为 64K 的 maxReceivedMessageSize.

You should to see if the service has the same maxReceivedMessageSize="4194304" as the client and if the XML is indeed smaller than the 4,194,304 byte limit that is set. WCF defaults to a maxReceivedMessageSize of 64K.

更新:

我注意到您的配置显示为 basicHttpBinding 配置客户端，但配置仅显示 wsHttpBinding.wsHttpBinding 配置将被 WCF 忽略，因为它不属于 basicHttpBinding.如果客户端配置文件没有 basicHttpBinding 元素，那么在 .NET 4 中将使用默认元素.如果这是真的，那么您将遇到上述 64K 限制.

I noticed your config shows the client being configured for basicHttpBinding but the config only shows a wsHttpBinding. The wsHttpBinding config would be ignored by WCF since it doesn't pertain to basicHttpBinding. If the client config file doesn't have a basicHttpBinding element then in .NET 4 a default one is being used. If this is true then you'll run into the 64K limit described above.
