为什么此urlencode JSON GET请求无法正常工作？

Question

$word = $_GET['search'];
$json = json_encode('{"query":{"match":{"name":"'.$word.'"}}}');
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://10.128.0.2:9200/testers/test/_search' . urlencode($json));
$resp = curl_exec($curl);

$word is filled from the URL and this is working normally. $resp isn't coming back with any value. 'name' is the name of elasticsearch field.

I am using PHP to run this curl request as per elasticserch except all in one URL. Are there any better ways to do this from PHP code?

如果使用的是GET调用，则需要在source查询字符串参数中传递查询：

curl_setopt($curl, CURLOPT_URL, 'http://10.128.0.2:9200/testers/test/_search?source=' . urlencode($json));
