CURLOPT_VERBOSE不起作用 [英] CURLOPT_VERBOSE not working

问题描述

Windows 7 x64
PHP 7.2.2 x64

我正在尝试查看简单的请求有效负载，因此我已按 https://docstore.mik.ua/orelly/webprog/pcook/ch11_07.htm

I am trying to view a simple request payload so I have created a PHP file per https://docstore.mik.ua/orelly/webprog/pcook/ch11_07.htm

<?php
$c = curl_init('https://www.google.com');
curl_setopt($c, CURLOPT_VERBOSE, 1);
curl_setopt($c, CURLOPT_POST, 1);
curl_setopt($c, CURLOPT_POSTFIELDS, 'monkey=uncle&rhino=aunt');
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$page = curl_exec($c);
curl_close($c);

但与示例所示的我可以期望得到的东西一样，我绝对没有输出，

but I get absolutely no output unlike the example which shows that I can expect something like:

* Connected to www.example.com (10.1.1.1)
> POST /submit.php HTTP/1.1
Host: www.example.com
Pragma: no-cache
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */*
Content-Length: 23
Content-Type: application/x-www-form-urlencoded

monkey=uncle&rhino=aunt* Connection #0 left intact
* Closing connection #0

$ page 包含Google 404页面，所以我知道请求成功。

$page contains a Google 404 page so I know the request is succeeding.

有人知道我是否需要解决其他设置或是否需要明显地做错了什么？

Does anyone know if there are other settings which I need to address or if I am doing something blatantly wrong? In particular, I am interested in the body of the payload.

是的，我知道Google卷曲并不是特别有用；我正在尝试使这个简单的示例正常工作，以便调试出神秘地失败的API交互。

Yes, I am aware that curl'ing Google isn't particularly useful; I am trying to get this simple example to work so that I can debug an API interaction which is mysteriously failing.

每个注释请求的更新

我不能执行 curl -v ，但是 print_r（curl_version（））; 产生：

I cannot do curl -v but print_r( curl_version() ); produces:

Array

推荐答案

tl; dr

CURLOPT_STDERR 必须设置为特定的值。

设置 curl_setopt（$ c，CURLOPT_STDERR，fopen（'/ curl.txt'，'w +'）） ; 解决了我的问题。

事实证明， curl_setopt（ $ c，CURLOPT_VERBOSE，1）; 由于某种原因（我尚未发现）未将输出打印到STDERR。

As it turns out curl_setopt($c, CURLOPT_VERBOSE, 1); is not printing the output to STDERR for some reason which I have not uncovered. I did not find the output in any of my PHP, Apache, nor Event Viewer logs.

设置 curl_setopt（$ c，CURLOPT_STDERR，fopen之后，我没有在任何PHP，Apache或Event Viewer日志中找到输出。

After setting curl_setopt($c, CURLOPT_STDERR, fopen('/curl.txt', 'w+'));, I was able to see the output in the curl.txt file.

（'/curl.txt'，'w +'））; ，我能够在 curl.txt 文件中看到输出。 / p>

我不确定这是否特定于Windows环境。

I am not sure if this is specific to Windows environments.
