java.net.MalformedURLException:无协议:GET https://www.googleapis.com/customsearch/v1?key=AIzaSyCS26VtzuCs7bEpC821X_l0io_PHc4-8tY&cx=017576662512468239146:omuauf_lfve&q=random

您应该删除开头的GET
;)
您应该通过以下方式替换您的代码:
URL url = new URL("https://www.googleapis.com/customsearch/v1?key=AIzaSyCS26VtzuCs7bEpC821X_l0io_PHc4-8tY&cx=017576662512468239146:omuauf_lfve&q=" + arg);
网址永远不会以GET
或POST
或其他类似内容开始;)
答案 1 :(得分:1)
网址应该以转让协议开始,GET https://www.googleapis.com/customsearch/v1?key=AIzaSyCS26VtzuCs7bEpC821X_l0io_PHc4-8tY&cx=017576662512468239146:omuauf_lfve&q=random
以GET
开头,这就是收到异常的原因。
将其更改为https://www.googleapis.com/customsearch/v1?key=AIzaSyCS26VtzuCs7bEpC821X_l0io_PHc4-8tY&cx=017576662512468239146:omuauf_lfve&q=random
