Answer 1

查询字符串由一系列字段 - 值对组成。内每对，字段名称和值用等号分隔，＆＃39; =＆＃39 ;.这对系列由＆符号分隔，＆＃39;＆＃39;

尝试改为

String urlAPI = "http://www.domain.com/api.php?msg="+msg+"&mobile="+mobile;

Answer 2

尝试编码查询参数：

URLEncoder.encode（“msg =”+ msg +“＆amp; mobile =”+ mobile，“UTF-8”）;

所以您的网址为http://www.domain.com/api.php?msg%3D%20Hello%26mobile%3D%201234567890
