类stdClass的对象无法转换为字符串PHP问题

标签: php object jira jira-rest-api

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);

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'; 
    }
