虽然 curl 的以下输出提供了有用的 header 信息，但它不提供负载信息。例如，我希望在提供的调试信息中看到 {"jason_index","json_value"}。
1.) 是否可以在详细模式下内联显示负载？
2.) 查看由 cURL 处理的已发送负载的最佳方式是什么？

cURL 语句示例
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_STDERR, fopen(dirname(__FILE__) . "/headers.txt", "w+"));
$result = curl_exec($ch);
最佳答案
我最近遇到了这个问题，我设法查看发生了什么的唯一方法是使用调试代理，例如:
- burp suite - Linux/Windows/Mac (Java)
- fiddler - window
其他解决方案是使用数据包检查器(此选项不会让您看到HTTPS 流量):
带有代理的解决方案易于设置，只需安装和使用:
curl_setopt($ch, CURLOPT_PROXY, 'localhost:8080'); // default for burp suite
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // ignore certs while connecting to https
关于php cURL CURLOPT_VERBOSE 不显示负载，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15558520/
