php curl multipart / form-data无法处理

Question

我有简单的数组;

 [specifics] => Array
        (
            [0] => RT
            [1] => 2S
        )

然后我创建它来查询;

http_build_query($array);

specifics%5B0%5D=RT&specifics%5B1%5D=2S

两者都不起作用。

curl_setopt($ch3, CURLOPT_HEADER, 1);
curl_setopt($ch3, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
curl_setopt($ch3, CURLOPT_URL, $info2['url']);
curl_setopt($ch3, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch3, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch3, CURLOPT_POST, 1);
curl_setopt($ch3, CURLOPT_POSTFIELDS, $query);

这是我正在使用的代码。

Answer 1

某些远程服务器无法识别查询中的“％5B0％5D”

specifics%5B0%5D=RT&specifics%5B1%5D=2S 

尝试以下

http_build_query($array, '', '&');
