CURL Get Request with a parameter that contains a GET url
提问by Maxim Laco
I'm trying to make a cURL GETto scrape a Facebook Graph object:
我正在尝试制作一个 cURLGET来抓取 Facebook Graph 对象：
GET https://graph.facebook.com/?id=**OBJECT_URL**&scrape=true&method=post
In my case, OBJECT_URLcontains GETparameters:
就我而言，OBJECT_URL包含GET参数：
https://www.example.com/og.php?a=b&c=d
For that reason I can't have it as a GETparameter in file_get_contents()or CURLOPT_URL, as it'd turn out something like this:
出于这个原因，我不能将它作为or 中的GET参数，因为它会变成这样：file_get_contents()CURLOPT_URL
https://graph.facebook.com/?id=**https://www.example.com/og.php?a=b&c=d**&scrape=true&method=post
Is there a way to pass it as a GETparameter in a way similar to CURLOPT_POSTFIELDS?
有没有办法以GET类似于的方式将其作为参数传递CURLOPT_POSTFIELDS？

You need to escape your parameters, the http_build_queryfunction will be useful:
您需要转义参数，http_build_query函数将很有用：
$query = http_build_query([
'id' => 'http://foo?a=1&b=2',
'scrape' => true,
'method' => 'post'
]);
$url = "https://graph.facebook.com/?".$query;
var_dump($url);
This will output:
这将输出：
https://graph.facebook.com/?id=http%3A%2F%2Ffoo%3Fa%3D1%26b%3D2&scrape=1&method=post
