为什么cURL总是返回状态码？ [英] Why does cURL always return a status code?

问题描述

我有一些PHP代码调用cURL库。我使用它来获取JSON数据。

I have some PHP code that calls into the cURL library. I'm using it to get JSON data.

我设置cURL选择'CURLOPT_RETURNTRANSFER'为1，但仍然获得状态代码..

I have set cURL opt 'CURLOPT_RETURNTRANSFER' to 1, but still get status code..

代码如下：

<?php
function fetch_page($url)
{

    $ch = curl_init();

    $array = array(
        'include'=>'ayam'
    );

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $array);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

    $result = curl_exec ($ch);
    curl_close ($ch);

    return $result;
} 

$return  = fetch_page(MY_LINK_URL);

echo json_decode($return);
?>

推荐答案

代码看起来完全正确。尝试 var_dump（$ result），然后返回它，看看它是什么。

The code looks totally correct. Try var_dump($result) before returning it to see what it is exactly.

另外，将 CURLOPT_HEADER 设置为1并检查浏览器中输出的视图源;这两个都可以帮助调试的问题。

Also, set CURLOPT_HEADER to 1 and check the view source of the output in your browser; both of these can help debug the issue. Edit the question and post the results if so we can help more effectively.

更新：由于您使用的是HTTPS，因此也可以添加

Update: Since you are using HTTPS, also add

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
