如何在Linux上使用QProcessEnvironment设置代理地址？ [英] How to set Proxy Address using QProcessEnvironment on Linux?

问题描述

我遇到一个简单的问题在Qt。我想使用Qt设置代理地址。设置代理地址的命令

I am stuck with a simple issue in Qt. I want set proxy address using Qt. The command to set proxy address

 export http_proxy=http://wwgw.abcd.com:8080

工作正常，如果由终端手动传递。但如果使用QProcess运行相同的命令，它会失败，而不设置代理。甚至，我尝试QProcessEnvironment作为

works fine if passed by a terminal manually. but If the same command is run using QProcess, it fails without setting proxy. Even, I tried with QProcessEnvironment as

QProcess process_setupProxyServerUrl;
QProcessEnvironment env = QProcessEnvironment::systemEnvironment();

QString cmd = "http://wwgw.abcd.com:8080";

env.insert("HTTP_PROXY", cmd);
process_setupProxyServerUrl.setProcessEnvironment(env);

但这也无法设置代理地址。 QProcessEnvironment对我来说是新的。

But this also fails in setting up proxy address. QProcessEnvironment is new for me. So may be i might be using it in wrong way.

在我的应用程序中，我需要根据用户的选择更改代理地址（在运行时）。

In my application, I need to change the proxy address according to users choice (at run time).

使用Qt的任何方式都会有帮助。请提供一些建议/建议以解决此问题。

Any way using Qt would be helpfull. Please provide some suggestions/ideas to resolve this issue.

推荐答案

尝试类似

QProcess process_setupProxyServerUrl;
QProcessEnvironment env = QProcessEnvironment::systemEnvironment();
env.insert("HTTP_PROXY", "http://wwgw.abcd.com:8080");
process_setupProxyServerUrl.setProcessEnvironment(env);

为什么使用导出？这只是一个可执行文件，而不是环境键

Why did you use export ? This is just an executable, not the environment key
