远程服务器返回一个意外的响应：（400）错误的请求，WCF

Question

我试图发送图像到我的WCF，当我得到这个。

远程服务器返回了意外的响应：（400）错误的请求。

一切工作正常发送到WCF和图像不是那么大〜90kb。我在这方面发现了很多线索，但没有什么能帮助我。我试图增加大小限制，但这不起作用。

的web.config

    } 
    produkt.ID = 7; 
    itemsTA.InsertProdukt(produkt.Namn, produkt.Pris, produkt.Beskrivning, produkt.LagerAntal, bmpAsByte); 
    itemsTA.InsertGenre(produkt.Typ, produkt.ID); 
    DataSet dataset = new DataSet(); 
    itemsTA.Adapter.Update(dataset); 
}

maxReceivedMessageSize属性需要存在于服务边界，服务和消费者的两端。所以你需要在你的客户端配置中添加一个绑定元素。

UPDATE

您需要包括从web.config绑定在你的服务的app.config：

<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> 

然后你就可以在你的服务端点在您的应用程序引用此绑定元素.config通过使用端点bindingConfiguration属性，并在这种情况下，您将其设置为与wsHttpBinding元素的名称相同的值，即“WSHttpBinding_IService”。

例如

<endpoint address="" 
      binding="wsHttpBinding" 
      contract="WcfDataLager.IService" 
      bindingConfiguration="WSHttpBinding_IService">
