我有一个网址,返回的是这样的JSON对象:
{ "expires_in":5180976, "access_token":"AQXzQgKTpTSjs-qiBh30aMgm3_Kb53oIf-VA733BpAogVE5jpz3jujU65WJ1XXSvVm1xr2LslGLLCWTNV5Kd_8J1YUx26axkt1E-vsOdvUAgMFH1VJwtclAXdaxRxk5UtmCWeISB6rx6NtvDt7yohnaarpBJjHWMsWYtpNn6nD87n0syud0" }
我想获得access_token价值。那么如何通过PHP检索它呢?
access_token
$json = file_get_contents(‘url_here’); $obj = json_decode($json); echo $obj->access_token;
为此,file_get_contents需要allow_url_fopen启用它。可以通过在运行时完成以下操作来实现:
file_get_contents
allow_url_fopen
ini_set("allow_url_fopen", 1);
您也可以使用curl获取网址。要使用卷曲,可以使用中发现的例子在这里:
curl
$ch = curl_init(); // IMPORTANT: the below line is a security risk, read https://paragonie.com/blog/2017/10/certainty-automated-cacert-pem-management-for-php-software // in most cases, you should set it to true curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_URL, 'url_here'); $result = curl_exec($ch); curl_close($ch); $obj = json_decode($result); echo $obj->access_token;
