如何仅获取此字符串中的访问令牌？

Question

{"access_token":"OeB89uEWZZzLPLMIsVBvJtIlnObM1sX7NNNWqwtjdzI.8LlxO2skN028HmcMw8F_BDiqEj9kDRfdVWc9f02WmiY","expires_in":43199,"scope":"","token_type":"bearer"}

如何仅通过access_token访问它，如下所示：

$str = "OeB89uEWZZzLPLMIsVBvJtIlnObM1sX7NNNWqwtjdzI.8LlxO2skN028HmcMw8F_BDiqEj9kDRfdVWc9f02WmiY";

Answer 1

以这种方式获取令牌，

<?php

$t = '{"access_token":"OeB89uEWZZzLPLMIsVBvJtIlnObM1sX7NNNWqwtjdzI.8LlxO2skN028HmcMw8F_BDiqEj9kDRfdVWc9f02WmiY","expires_in":43199,"scope":"","token_type":"bearer"}';

$a = json_decode($t);

print_r($a->access_token);

?>

输出

OeB89uEWZZzLPLMIsVBvJtIlnObM1sX7NNNWqwtjdzI.8LlxO2skN028HmcMw8F_BDiqEj9kDRfdVWc9f02WmiY

Answer 2

您可以使用json_decode()

<?php

$json = '{"access_token":"OeB89uEWZZzLPLMIsVBvJtIlnObM1sX7NNNWqwtjdzI.8LlxO2skN028HmcMw8F_BDiqEj9kDRfdVWc9f02WmiY","expires_in":43199,"scope":"","token_type":"bearer"}';

$array = json_decode($json,true);

print_r($array['access_token']);

输出：-{https://3v4l.org/MPuCn
