PHP curl: CURLOPT_URL, CURLOPT_POST, and CURLOPT_POSTFIELDS
提问by NightHawk
If I have a URL that looks like this:
如果我有一个如下所示的 URL：
$url = 'http://domain.com/?foo=bar';
And then execute curl as follows:
然后执行 curl 如下：
$resource = curl_init();
curl_setopt($resource, CURLOPT_URL, $url);
curl_setopt($resource, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($resource);
curl_close($resource);
I understand that I make this request via GET (default).
我知道我是通过 GET（默认）发出这个请求的。
Now if I set the following option in the same scenario:
现在，如果我在同一场景中设置以下选项：
curl_setopt($resource, CURLOPT_POST, 1);
I understand it uses POST instead of GET, but does it then POST foowith a value of bar? Or would the proper way for that be:
我知道它使用 POST 而不是 GET，但是它是否使用 POSTfoo值bar？或者正确的方法是：
$url = 'http://domain.com/';
$post = 'foo=bar';
$resource = curl_init();
curl_setopt($resource, CURLOPT_URL, $url);
curl_setopt($resource, CURLOPT_POST, 1);
curl_setopt($resource, CURLOPT_POSTFIELDS, $post);
curl_setopt($resource, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($resource);
curl_close($resource);
And what happens if I do this (i.e. submit the value in the URL and via CURLOPT_POSTFIELDS):
如果我这样做（即在 URL 中并通过 CURLOPT_POSTFIELDS 提交值）会发生什么：
$url = 'http://domain.com/?foo=bar';
$post = 'foo=bar';
$resource = curl_init();
curl_setopt($resource, CURLOPT_URL, $url);
curl_setopt($resource, CURLOPT_POST, 1);
curl_setopt($resource, CURLOPT_POSTFIELDS, $post);
curl_setopt($resource, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($resource);
curl_close($resource);
How will the data be submitted in that scenario?
在这种情况下如何提交数据？

The difference between POST and GET is how the server retrieves the data. As you have set CURLOPT_POST to true, the server normally receives the parameters via the CURLOPT_POSTFIELDS value (i.e. the parameters in the HTTP body) and presumably ignore the parameters sent in the URL string - but that really depends on the individual server.
POST 和 GET 之间的区别在于服务器如何检索数据。由于您已将 CURLOPT_POST 设置为 true，服务器通常通过 CURLOPT_POSTFIELDS 值（即 HTTP 正文中的参数）接收参数，并且可能会忽略 URL 字符串中发送的参数 - 但这实际上取决于单个服务器。
