WCF遠程服務器返回意外的響應：（400）錯誤的請求

Question

我使用WCF的basicHttpBinding協議。

我收到大Class<T>（沒問題）。

但是我送大Class<T>我得到這個錯誤

拋出異常：在 'System.ServiceModel.ProtocolException' System.ServiceModel.Internals.dll

附加信息：遠程服務器返回的意外 迴應：（400）錯誤的請求。

我的服務器配置是

Answer 1

你不能一個大型對象發送給服務的原因是因爲你永遠不分配您定義basicHttpBinding到服務端點。

在服務的配置，您有：

<bindings> 
    <basicHttpBinding> 
    <binding name="NewBinding0"..... 

但是當你定義端點，你不分配「NewBinding0」吧：

<endpoint behaviorConfiguration="myHttpBindingEndPointBihaviour" 
     binding="basicHttpBinding" bindingConfiguration="".... 

由於bindingConfiguration元素沒有按如果不指定綁定配置，則會使用默認值basicHttpBinding，這就是您無法發送大型對象的原因。

通過bindingConfiguration屬性是這樣分配「NewBinding0」到您的端點：

<endpoint behaviorConfiguration="myHttpBindingEndPointBihaviour" 
     binding="basicHttpBinding" bindingConfiguration="NewBinding0"..... 

您的服務應該能夠當客戶端發送他們接受更大的物體。
