php - curl post后，如何检查postfield - 调试

Question

我有一个类似这样的卷发帖子

curl_setopt($ch, CURLOPT_URL,$cpUrl);
curl_setopt($ch, CURLOPT_POST, true);  
curl_setopt($ch, CURLOPT_POSTFIELDS, $varpost); // post parameters
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Return the output in string format
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_NOBODY, true);
$output = curl_exec ($ch); // Execute

我如何在 curl_close ($ch) 之后检查；发送了哪些帖子字段变量？请帮忙

Answer 1

how can i check after curl_close ($ch); what post field variables were sent?

您的脚本提供随 CURLOPT_POSTFIELDS 一起发送的变量。选项，所以如果 cURL 成功执行，你已经有了这些变量:

...
$output = curl_exec($ch); // Execute

//show the POST fields if they were sent successfully
if($output) print_r($varpost);
else echo "cURL failed: no POST fields sent";
