无法使file_get_contents工作 [英] Unable to file_get_contents to work

问题描述

我正在使用facebook graph api来检索登录的用户信息.

I am using facebook graph api, to retrieve logged in user's info.

$facebookdata = json_decode(file_get_contents('https://graph.facebook.com/me?access_token=' . $fb_accesstoken . '&fields=name,picture'),true);

现在，当我 var_dump 时，我将得到null.我确实尝试转到url https://graph.facebook.com /me?access_token = ACCESS_TOKEN& fields = id，名称，图片.它显示名称和photourl.

Now When I var_dump I get null. I did try to goto url https://graph.facebook.com/me?access_token=ACCESS_TOKEN&fields=id,name,picture. It shows the name and photourl.

感谢您的帮助.

推荐答案

检查是否已启用 allow_url_fopen 您的php.ini.否则请修改，因为那样一来file_get_contents将无法从http URL读取.

Check if allow_url_fopen is enabled in your php.ini. Otherwise adapt, because file_get_contents will not be able to read from http URLs then.

第二，提高您的 error_reporting 级别.它应该已经告诉你了.

Second, raise your error_reporting level. It should have told you so.

如果未收到错误消息，则可能阻止了PHP user_agent的访问.还有另一个php.ini设置.另外，也可以尝试 curl .

If you get no error message, then access with the PHP user_agent might be blocked. There is another php.ini setting for that. Also alternatively, just try curl.
