我从Jira Atlassian API中提取信息，我使用其他代码，它工作正常，我将其更改为json，所有信息都作为对象返回。
但是在这种情况下，我收到此服务器错误： PHP Catchable致命错误：第411行的/usr/local/vhosts/999/webspace/httpdocs/mysite/filters1.php中无法将类stdClass的对象转换为字符串
现在这里是试图运行的代码：
$username = 'xxx@gmail.com';
$password = 'xxxxxxx';
$url = 'xxx.atlassian.net/rest/api/2/search?jql=project+%3D+bug+AND+component+%3D+%22issues%22+AND+status+in+(Open,+Reopened)';
$headers = array(
'Accept: application/json',
'Content-Type: application/json'
);
$ch = curl_init();
$test = "This is the content of the custom field.";
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
//curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
$result = curl_exec($ch);
$issue_json = json_decode($result);
$ch_error = curl_error($ch);
if ($ch_error) {
echo "cURL Error: $ch_error";
} else {
echo $issue_json;
}
curl_close($ch);
正如我所提到的那样，如果我将代码改为
，则会返回上面的错误 $result = curl_exec($ch);
//$issue_json = json_decode($result);
然后我回应$结果它工作并返回我需要的一切，但作为一个巨大的字符串，而不是像我想要的对象。我将下面的整个字符串格式化，使其更具可读性。 我搜索了一些类似的问题，我想我需要做这样的事情：
foreach($string as $strings)
{
echo $strings;
}
但我不太熟悉这种东西只是基本的PHP所以我有点失落

函数json_decode不返回字符串。
查看该功能的文档。
http://fr2.php.net/function.json-decode.php
问题在于你试图回应对象。以下代码有问题。
echo $issue_json;
您可以使用var_dump查看从json_decode返回的对象的结构。
var_dump($issue_json);
答案 1 :(得分：0)
要回答问题标题，如果您的对象没有__string方法使用它作为字符串将抛出异常。 （我认为这在5.2中有所改变），所以要在你需要的跳跃上进行无法编码的字符串转换：
if (is_object($arg)) {
$arg = method_exists($arg, '__toString') ? (string)$arg : 'Object';
}
