Question

我正在尝试输出来自JIRA的特定信息，我有JSON循环并显示了结果，但是嵌套最远的结果仅显示了第一个字符。

我尝试遵循建议here，但这似乎是为了获得顶级结果，我似乎无法使其与我的代码一起使用。

<?php
$username = '*************';
$password = '*************';

$url = '<JIRA-DOMAIN>/rest/api/2/search?jql=project=ICI&fields=key,summary,description&maxResults=10';

$curl = curl_init();
curl_setopt($curl, CURLOPT_USERPWD, "$username:$password");
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);

$issue_list = (curl_exec($curl));
$json = json_decode($issue_list, TRUE);
?>

<div class="toto">
    <?php
    foreach($json['issues'] as $obj){   ?>

        <h2><?php echo $obj['id']; ?></h2>

          <?php foreach($obj['fields'] as $parc){ ?>

             <a href="<?php echo $parc['summary']; ?>">
                 <span><?php echo $parc['description']; ?></span>
             </a>

       <?php }
     } ?>
</div>

当我回显$ issue_list时，我得到以下信息：

输出缩短

{
    "expand":"schema,names",
    "startAt":0,
    "maxResults":10,
    "total":9,
    "issues":[
        {

"expand":"operations,versionedRepresentations,editmeta,changelog,renderedFields",
        "id":"10058",
        "self":"<domain>/rest/api/2/issue/10058",
        "key":"ICI-9",
        "fields":{
            "summary":"ToS and PP button removal",
            "description":"The Terms of Service and Privacy Policy buttons go to a page on the website so they can't use the app after. They also go to a page of nothing because they aren't written so they need to be deleted"
        }
    },
    {
        "expand":"operations,versionedRepresentations,editmeta,changelog,renderedFields",
        "id":"10048",
        "self":"<domain>/rest/api/2/issue/10048",
        "key":"ICI-1",
        "fields":{
            "summary":"Create Launch Image",
            "description":"Create launch image for app. Resolution should be: 2048px × 1536px\r\n\r\n[~james.whitaker] I got this info from [here|https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/launch-screen/]"
        }
    }
]
}

但是循环输出仅显示描述和摘要的第一个字符，如下所示，但显示整个ID。

任何帮助将不胜感激。

Answer 1

您的问题出在以下foreach循环中：

     <?php foreach($obj['fields'] as $parc){ ?>

         <a href="<?php echo $parc['summary']; ?>">
             <span><?php echo $parc['description']; ?></span>
         </a>

   <?php }

$parc的值将为$obj['fields']['summary']，然后在循环中为$obj['fields']['description']，因此当您尝试使用['summary']对其进行索引时，将使用无效的索引，即转换为0（因此为单个字符）。请尝试以下操作（删除foreach）：

     <a href="<?php echo $obj['fields']['summary']; ?>">
         <span><?php echo $obj['fields']['description']; ?></span>
     </a>

Answer 2

我认为fields不是数组。

将$parc['summary']更改为$obj['fields']['summary']

循环JSON数据仅显示第一个字符
