如何在 android 應用程序上隨機更改 WebView User-Agent？

Question

我想在每次應用隨機啟動時更改我的WebView User-Agent ，我該怎么做？

這是我的WebView用戶代理

   Mozilla/5.0 (Linux; U; Android 4.3; en-us; SM-N900T Build/JSS15J) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
   Mozilla/5.0 (Linux; U; Android 4.3; de-de; GT-I9300 Build/JSS15J) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
   Mozilla/5.0 (Linux; U; Android 2.2.1; en-us; Nexus One Build/FRG83) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

我想從上面的列表中隨機加載User-Agent 。

Answer 1

這很簡單！ 你可以通過這樣的array來做到這一點。

//Load User agent randomly
  

    val randomuseragent = arrayOf("   Mozilla/5.0 (Linux; U; Android 2.2) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
        ",
    "Mozilla/5.0 (Linux; U; Android 4.3; en-us; SM-N900T Build/JSS15J) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
        ",
     "Mozilla/5.0 (Linux; U; Android 4.3; de-de; GT-I9300 Build/JSS15J) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
        " ,
     "Mozilla/5.0 (Linux; U; Android 2.2.1; en-us; Nexus One Build/FRG83) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
        ")
    
     val randomUserAgent = randomuseragent[(Math.random() * randomuseragent.size).toInt()]
            val USER_AGENT =(randomUserAgent)
            /// Set User Agent
            myWebView.getSettings().setUserAgentString(USER_AGENT);
            ///
