如果你使用 urlencode ，你只需要对值进行编码，而不是整个查询字符串。执行此操作（并保持查询数据在整齐数组中）的有效方法是使用 http_build_query ：

If you are using urlencode, you'll just want to encode the values, not the whole query string. An efficient way to do this (and keep your query data in neat arrays) is with http_build_query:

$url= 'https://www.test.com/test.php?';

$data = array('p1' => '{1250.feed}',
              'p2' => '{jt2221}',
              'p3' => '{1330}',
              'p4' => '{1234567890}',
              'p5' => '{2016-02-04 20:05:34}',
              'p6' => '{New York}',);

$msg = http_build_query($data);

$url .= $msg;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
curl_close($ch);
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

var_dump($http_status);
var_dump($result);
