WCF客户端请求返回错误请求（400）

Question

我的客户端应用程序使用托管在本地IIS中的WCF Web服务。此Web服务用于上传图像。一旦图像尺寸变大，它会提出错误的请求（400）。

客户端被配置为动态获取Web服务URL。

客户端代码

string serviceUrl=GetUrl(); /* http://localhost:85/ImageUploaderService.svc */ 

TimeSpan timeOut = new TimeSpan(0, 30, 0); 

EndpointAddress endPoint = new EndpointAddress(serviceUrl);  


BasicHttpBinding binding = new BasicHttpBinding() 
{ 
    CloseTimeout = timeOut, 
    MaxReceivedMessageSize = 65536, 
    OpenTimeout = timeOut, 
    ReceiveTimeout = timeOut, 
    SendTimeout = timeOut, 
    MaxBufferSize = 65536, 
    MaxBufferPoolSize = 524288, 
    UseDefaultWebProxy = true, 
}; 

binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas() 
{ 
    MaxArrayLength = 64000000, 
    MaxStringContentLength = 8192, 
    MaxDepth = 32, 
    MaxNameTableCharCount = 16384, 
    MaxBytesPerRead = 4096 
}; 

client = new ImageUploaderServiceClient(binding, endPoint); 

Web服务端

<basicHttpBinding> 
    <binding maxBufferSize="64000000" maxReceivedMessageSize="64000000" maxBufferPoolSize="64000000"> 
     <readerQuotas maxDepth="64000000" maxStringContentLength="64000000" maxArrayLength="64000000" maxBytesPerRead="64000000" /> 
     <security mode="None"/> 
    </binding> 
    </basicHttpBinding> 

什么是我做了错误的。请通过正确的方式指导我。

您应该增加MaxReceivedMessageSize在客户端以及可能：

BasicHttpBinding binding = new BasicHttpBinding() 
{ 
    MaxReceivedMessageSize = 64000000, 
    MaxBufferSize = 64000000, 
    MaxBufferPoolSize = 64000000, 
// ..... 
}; 
binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas() 
{ 
    MaxArrayLength = 64000000, 
    MaxStringContentLength = 64000000, 
    MaxDepth = 64000000, 
    MaxBytesPerRead = 64000000 
}; 

我曾经有过同样的问题 - 服务器和客户端绑定配置应该是相同的。
