客户端通过代理服务器（CMWap）遇到的问题

移动的 如果客户端对标准的http头的某个域进行赋值可能是徒劳无功的，移动会重新对标准的头进行默认的处理，当然，每个域有固定的域值范围，选一个标准的值是没问题的。扩展自定义的域是可以的。 估计这么做的出发点是安全方面的吧 联通的 先说几个http错误吧： 400：去掉“HTTP::EHost”设置就没问题了。 500：服务器没有找到请求资源 302：加上“HTTP::EContentType” 最后进过几天的折磨终于搞定了，联通的和移动的都可以了！ post头： _LIT8( KContentText, "text/plain");//上传字符串用 _LIT8( KContentText,"multipart/form-data");//上传文件用，例如jsp _LIT8( KUserAgentSimpleClient, "SimpleClient 1.0" ); _LIT8( KHttpVersion11,"HTTP/1.1" ); _LIT8( KAccept,"Accept"); _LIT8(KUserAgent, "LARK/1.3.0"); RStringF method = iSession.StringPool().StringF( HTTP::EPOST,RHTTPSession::GetTable()); iTransaction = iSession.OpenTransactionL( uri, *this, method ); RHTTPHeaders hdr = iTransaction.Request().GetHeaderCollection(); SetHeaderL( hdr, HTTP::EUserAgent, KUserAgentSimpleClient ); SetHeaderL( hdr, HTTP::EContentType, KContentText); SetHeaderL( hdr, HTTP::EHTTPVersion, KHttpVersion11); SetHeaderL( hdr, _L8("Proxy-Connection"), _L8("Keep-Alive") ); SetHeaderL( hdr, _L8("AcceptType"), _L8("REGISTER") );//扩展自定义http头域 get： SetHeaderL(hdr, HTTP::EUserAgent, KUserAgent); SetHeaderL(hdr, HTTP::EAccept, KAccept); SetHeaderL( hdr, _L8("Proxy-Connection"), _L8("Keep-Alive") ); 下面是头域有关的方法： void SetHeaderL(RHTTPHeaders aHeaders, TInt aHdrField, const TDesC8& aHdrValue)//设置标准httpheader { RStringF valStr = iSession.StringPool().OpenFStringL(aHdrValue); CleanupClosePushL(valStr); THTTPHdrVal val(valStr); aHeaders.SetFieldL(iSession.StringPool().StringF(aHdrField, RHTTPSession::GetTable()), val); CleanupStack::PopAndDestroy(); // valStr } void SetHeaderL(RHTTPHeaders aHeaders,const TDesC8& aHdrField, const TDesC8& aHdrValue)//设置非标准httpheader { TInt leaveValue; RStringF contTypeStr; RStringF contTypeStrfield; TRAP(leaveValue, contTypeStr = iSession.StringPool().OpenFStringL(aHdrValue)); if (leaveValue != KErrNone ) { User::InfoPrint(_L("SetNewHeader() : StringPool().OpenFStringL() aHdrValue.
