Php 为什么cURL exec还返回我的POST请求的头数据？

我只是测试一些图像压缩代码，然后上传到imgurapi。但是，除了获取响应内容，我似乎还获取了头数据，我不知道如何解析JSON。以下是我目前掌握的情况：

compress\u test.php

include("imgur_upload.php");
echo compress_and_upload();

function compress_and_upload(){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://api.imgur.com/3/image.json');
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // for localhost
    curl_setopt($ch, CURLOPT_HEADER, FALSE); // tried this but no change
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Client-ID ' . IMGUR_CLIENT_ID));
    curl_setopt($ch, CURLOPT_POSTFIELDS, array('image' => 'http://userserve-ak.last.fm/serve/300x300/51654499.png', 'type' => 'url'));

    $reply = curl_exec($ch);
    curl_close($ch);
    return $reply;
}

imgur\u upload.php

include("imgur_upload.php");
echo compress_and_upload();

function compress_and_upload(){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://api.imgur.com/3/image.json');
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // for localhost
    curl_setopt($ch, CURLOPT_HEADER, FALSE); // tried this but no change
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Client-ID ' . IMGUR_CLIENT_ID));
    curl_setopt($ch, CURLOPT_POSTFIELDS, array('image' => 'http://userserve-ak.last.fm/serve/300x300/51654499.png', 'type' => 'url'));

    $reply = curl_exec($ch);
    curl_close($ch);
    return $reply;
}

我所期待的只是我相信的JSON数据

我得到的是：

我在自己的服务器上运行了代码并使用了您的代码，但没有出现此问题。

您确定没有在某个位置设置

CURLOPT_HEADER

？如果您将其设置为

false

？@Brad Yup，我尝试将

CURLOPT_HEADER

设置为false，但我仍然得到了全部信息，因此无法解析JSON。我可以找到

{

但我真的不应该这么做。@paranoid android什么版本的php，什么操作系统，你是用CLI或类似mod_php的东西来运行它的吗？@Nirk php版本5.4.12，Windows 7 x64。我一直在用WAMP在浏览器中运行它，我以前从来没有遇到过这个问题。@paranoid android错误的处理方式是一样的（尝试使用无效ID）你有没有去他们那里注册以获得一个客户端id？因为我肯定没有分享我的。那没有关系。我想你的服务器没有解码GZ编码。我可以从结果开头和结尾的字符看出。我已经使用CURL多年了。我想你已经了解了一些事情，但我不知道如何启用它或者修复此问题。尝试添加：curl_setopt（$ch，CURLOPT_ENCODING'）；
