从REST API输出中解析JSON并将其放入相应的变量中

Question

我使用php并从下面的JIRA API获得输出，该输出使用 https://github.com/chobie/jira-api-restclient/blob/master/README.md 连接到工具。它取得的记录非常精细，但我只想要所有记录中的信息很少，因此写在print_r($issue['description'])的代码下面，但它会引发错误：

  

未捕获错误：无法使用chobie \ Jira \ Issue类型的对象作为数组

1. 我需要做些哪些更改来代替$ issue来获取这3条信息 - [id:protected]，[description]和[name]。

2. 如何计算找到的错误总数找到了chobie \ Jira \ Issue Object的数量？

代码：

$walker = new Walker($api);
$walker->push(
    'project = "SEA" AND (status != "closed" AND status != "resolved") ORDER BY priority DESC'
);

foreach ( $walker as $issue ) {
    print "<pre>";
    print_r($issue);
    print "</pre>";
}

所以$ issue打印下面的所有内容，但我只想得到[id：protected]，[description]和[name]。为了获得这3个信息，我需要做出哪些改变来代替$ issue。有人可以给我一些提示吗？

JSON：

Answer 1

得到答案，你需要先将对象转换为数组，获取数组字段并相应地解析它。

$walker = new Walker($api);
$walker->push('project = "SEA" AND (status != "closed" AND status != "resolved") ORDER BY priority DESC');

foreach ( $walker as $issue ) {
    $issue = $bugs->getFields();
    print "<pre>";
    print_r($issue);
    print_r(trim($issue['Status']['name']);
    print "</pre>";
}
