要在查询字符串中将数组传递给 php，您应该将 [] 添加到 identifier 并将每个项目添加为单独的条目，因此这样的事情应该可以工作:

To pass an array to php in query string, you should add [] to identifier and add every item as separate entry, so something like this should work:

nameValuePairs.add(new BasicNameValuePair("devices[]", device1));
nameValuePairs.add(new BasicNameValuePair("devices[]", device2));
nameValuePairs.add(new BasicNameValuePair("devices[]", device3));

现在，php 端的 $_POST['devices'] 将包含一个数组.

now, $_POST['devices'] on php side will contain an array.
