POST适用于Postman,但不适用于CURL

Question

使用邮递员,我发送一个POST(我的用户名和密码填写):

https://ssl.reddit.com/api/login?api_type=json&user=XXX&passwd=XXX&rem=True 

我收到一个包含modhash和cookie的回复.然后,我发送第二个POST邮递员到:

https://en.reddit.com/api/comment?api_type=json&text=7/1/15TEST&thing_id=t1_csa56v2

使用以下标题(XXX已确认并填写):

User-Agent: XXX
Cookie: reddit_session=XXX
X-Modhash: XXX

这提供了正确的响应,但是当我尝试在PHP中使用CURL执行相同的操作时,它会以USER_REQUIRED响应.我再一次确认cookie和modhash是正确的.

$name = 't1_csa56v2';
$text = 'NEWEST TEST 7/2/15 12:20am';
$url = 'https://en.reddit.com/api/comment';

$modhash = 'XXX';
$cookie = 'XXX';

$headerFields = array (
    'User-Agent' => 'XXX',
    'Cookie' => 'reddit_session='.$cookie,
    'X-Modhash' => $modhash 
);

$postFields = array (
    'api_type' => 'json',
    'text' => $text,
    'thing_id' => $name
);


$field_string = http_build_query($postFields);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headerFields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 3);
curl_setopt($ch, CURLOPT_POSTFIELDS, $field_string);
$response = curl_exec($ch);

我究竟做错了什么？为什么我不能得到相同的回复？

Answer 1

<?php 
error_reporting(E_ALL);
$name = 't1_csa56v2';
$text = 'NEWEST TEST 7/2/15 12:20am';
$url = 'https://en.reddit.com/api/comment';

$modhash = 'XXX';
$cookie = 'XXX';

$headerFields = array (
    'X-Modhash' => $modhash 
);

$postFields = array (
    'api_type' => 'json',
    'text' => $text,
    'thing_id' => $name
);



$ch = curl_init($url);
assert(curl_setopt_array($ch,
array(
        CURLOPT_AUTOREFERER => true,
        CURLOPT_BINARYTRANSFER => true,
        CURLOPT_COOKIESESSION => true,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_FORBID_REUSE => false,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_SSL_VERIFYPEER => false,
        CURLOPT_CONNECTTIMEOUT => 10,
        CURLOPT_TIMEOUT => 11,
        CURLOPT_ENCODING=>"",
        CURLOPT_USERAGENT=>'XXX',
        CURLOPT_COOKIE=>'reddit_session='.$cookie,
        CURLOPT_HTTPHEADER=>$headerFields,
        CURLOPT_POST=>true,
        CURLOPT_POSTFIELDS=>$postFields,
)));
$response = curl_exec($ch);

试试这个..不确定你到底做错了什么，但是用户代理应该设置为 CURLOPT_USERAGENT ，并且 cookie 应该设置为 CURLOPT_COOKIE ，你应该让curl为你编码，而不是使用 http_build_query ，你应该显式设置它到 POST 请求，因为默认情况下它是 GET 请求。还应该启用 E_ALL 错误报告
