QT发送http请求编码

QUrl params;
QTextCodec *utf8 = QTextCodec::codecForName("utf-8");
params.addQueryItem("signature",utf8->fromUnicode(QString::fromStdString("你们好")).toPercentEncoding());
params.addQueryItem("clientKey",utf8->fromUnicode(QString::fromStdString("/!@#$%*^*)\")).toPercentEncoding());

 

经过以上方式设置编码,能够保证服务的可以有效的收到数据.
