用WebClient 去下载数据时发现有服务器提交了协议冲突. Section=ResponseHeader Detail=CR 后面必须是 LF错误,解决办法
1.在app.config种添加 web 在 web.config种添加
<
system.net
>
<
settings
>
<
httpWebRequest
useUnsafeHeaderParsing="true" />
</
settings
>
</
system.net
>
useUnsafeHeaderParsing的值【该方法须在发送请求之前进行设定否则无效果】
public static bool SetAllowUnsafeHeaderParsing(bool useUnsafe) { //Get the assembly that contains the internal class System.Reflection.Assembly aNetAssembly = System.Reflection.Assembly.GetAssembly(typeof(System.Net.Configuration.SettingsSection)); if (aNetAssembly != null) { //Use the assembly in order to get the internal type for the internal class Type aSettingsType = aNetAssembly.GetType("System.Net.Configuration.SettingsSectionInternal"); if (aSettingsType != null) { //Use the internal static property to get an instance of the internal settings class. //If the static instance isn‘t created allready the property will create it for us. object anInstance = aSettingsType.InvokeMember("Section", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.GetProperty | System.Reflection.BindingFlags.NonPublic, null, null, new object[] { }); if (anInstance != null) { //Locate the private bool field that tells the framework is unsafe header parsing should be allowed or not System.Reflection.FieldInfo aUseUnsafeHeaderParsing = aSettingsType.GetField("useUnsafeHeaderParsing", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance); if (aUseUnsafeHeaderParsing != null) { aUseUnsafeHeaderParsing.SetValue(anInstance, useUnsafe); return true; } } } } return false; }
