问题描述

到目前为止，我可以使用QNetworkConfigurationManager :: allConfigurations（）扫描所有可用的WiFi，但每个的QNetworkConfiguration数据没有wifi信号强度。你能指点我如何获得这些数据吗？谢谢！

So far I am able to scan all the available wifi using QNetworkConfigurationManager::allConfigurations(), but the QNetworkConfiguration data for each of them does not have the wifi signal strength. Can you point me into how to get this data? Thanks!

推荐答案

您可以使用QProcess并运行命令行命令扫描WiFi网络。

You could use QProcess and run command line commands to scan for wifi networks. Use regular expressions to parse the command line output which contains all details of the wifi network.

如果您使用的是linux，则命令为iwlist scan

If you are using linux then the command is "iwlist scan"
