类stdClass的对象无法转换为字符串PHP问题

类stdClass的对象无法转换为字符串PHP问题,php,object,jira,jira-rest-api,Php,Object,Jira,Jira Rest Api,我从Jira Atlassian API获取信息,我使用了其他代码,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,我会遇到以下服务器错误: PHP可捕获致命错误:stdClass类的对象无法转换为第411行/usr/local/vhosts/999/webspace/httpdocs/mysite/filters1.PHP中的字符串 下面是我试图运行的代码: $username = 'xxx@gmail.com'; $password = 'xxxxxxx'; $

我从Jira Atlassian API获取信息,我使用了其他代码,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,我会遇到以下服务器错误: PHP可捕获致命错误:stdClass类的对象无法转换为第411行/usr/local/vhosts/999/webspace/httpdocs/mysite/filters1.PHP中的字符串

下面是我试图运行的代码:

$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);
正如我提到的,它返回上面的错误,但是如果我将代码更改为

 $result = curl_exec($ch);
 //$issue_json = json_decode($result);
然后我回显$result,它工作并返回我需要的所有内容,但作为一个巨大的字符串,而不是我想要的对象。我在下面格式化了整个字符串,使其更具可读性。 我在谷歌上搜索了一些类似的问题,我想我需要这样做:

foreach($string as $strings) 
{
     echo $strings;
}
但是我对这类东西不太熟悉,只是基本的php,所以我有点迷路了

函数
json\u decode
不返回字符串

请查看该函数的文档

问题是您试图回显对象。以下代码有故障

echo $issue_json;
您可以使用var_dump查看json_decode返回的对象的结构

var_dump($issue_json);

要回答问题标题,如果对象没有_字符串方法,将其用作字符串将引发异常。(我认为这在5.2中有所改变),因此要在跃点上进行未编码字符串转换,您需要:

    if (is_object($arg)) {                                                
      $arg = method_exists($arg, '__toString') ? (string)$arg : 'Object'; 
    }                                                                     

你在回显解码后的json对象,回显
$result
将为你提供解码后的字符串。多亏了这个技巧,我想因为我无法回显$issue\u json,我将无法访问以下内容:$issue\u json->issues[0]->self,但这确实很好,这是我想做的主要事情,但是var_dump也有助于在我搜索东西时使代码更容易阅读,请欣赏快速而有用的响应
