我正在执行这个 curl 帖子，如下所示：

//set POST variables
$url = 'https://api.vineapp.com/users/authenticate';


//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, 'username=email@example.com&password=password');


//execute post
$result = curl_exec($ch);
print_r(curl_getinfo($ch));
//close connection
curl_close($ch);

print_r($response);

当使用 mamp在我的本地机器上运行它时，它会成功返回一个 json 字符串，如下所示：

{"code": "", "data": {"username": "InstaBrand", "edition": "US", "userId": 1123456, "key": "key-value-string", "avatarUrl": "http://v.cdn.vine.co/r/avatars/21F43610771076328335136776192_263ec9b0577.0.2.jpg?versionId=nWh0YVdjXW2oxz0P7dild3Q5A4D5M53G"}, "success": true, "error": ""}

运行curl_getinfo时显示以下信息：

Array
(
    [url] => https://api.vineapp.com/users/authenticate
    [content_type] => application/json
    [http_code] => 200
    [header_size] => 260
    [request_size] => 197
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 1.105723
    [namelookup_time] => 0.486254
    [connect_time] => 0.620647
    [pretransfer_time] => 0.925538
    [size_upload] => 55
    [size_download] => 333
    [speed_download] => 301
    [speed_upload] => 49
    [download_content_length] => 333
    [upload_content_length] => 55
    [starttransfer_time] => 1.10562
    [redirect_time] => 0
    [redirect_url] => 
    [primary_ip] => 23.21.154.247
    [certinfo] => Array
        (
        )

    [primary_port] => 443
    [local_ip] => 192.168.15.128
    [local_port] => 57522
)

但是，当我在服务器上执行此操作时，它会返回 500错误，并且此信息是从以下位置返回的curl_getinfo：

Array
(
    [url] => https://api.vineapp.com/users/authenticate
    [content_type] => text/html
    [http_code] => 500
    [header_size] => 131
    [request_size] => 197
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 2.049556
    [namelookup_time] => 0.017791
    [connect_time] => 0.019114
    [pretransfer_time] => 0.047803
    [size_upload] => 55
    [size_download] => 87
    [speed_download] => 42
    [speed_upload] => 26
    [download_content_length] => -1
    [upload_content_length] => 0
    [starttransfer_time] => 2.049474
    [redirect_time] => 0
    [certinfo] => Array
        (
        )
)

故障排除：

  1. 将服务器上请求的 URL 更改为不同的 HTTPS URL = 成功响应
  2. 确保两个环境都运行相同的 php 版本
  3. 确保 php 和 curl timeout、 curlconnectiontimeout和 phpmax execution time有足够的时间

有谁知道为什么会发生这种情况，或者在不同的环境中遇到过类似的问题？
