我想在纯文本框中显示返回我的html代码.

This is my program. In this program I want to send request to a website (for example: http://www.adobe.com/products/muse.html)
I want to show the html code that return me in plain text box.

QUrl url("http://www.adobe.com/products/muse.html")

我想在此文件"中提供html代码

file.setFileName("thisfile.html");

if (!file.open(QIODevice::WriteOnly))
{
    std::cerr << "Error: Cannot write file "
    << qPrintable(file.fileName()) << ": "
    << qPrintable(file.errorString()) << std::endl

    return false;
}

http.setHost(url.host(),80);
http.post(url.toString(),"term=yyyy&loc=en_us&siteSection=products%3Amuse",&file);

此代码无法正常工作，当我显示文件时，请给我提供虚假的html代码.我该怎么办?

This code doesn't work correctly and when I show the file give me false html code. What do I have to do?

推荐答案

使用http.get()代替http.post()，因为POST方法需要设置服务器使用的其他Headers.

Use http.get() instead of http.post() as POST method requires to set other Headers used by server.

QHttp::get()方法也是异步.

由于您的情况很简单，只需要检索HTML响应，因此您应该进行HTTP GET恕我直言.

As your case is simple enough just to retrieve HTML response, you should go for HTTP GET IMHO. See difference between GET and POST method.
