JSON帖子从webservice返回格式化字符串中的答案（例如，我有一个带搜索框的网站，无论我在搜索框中输入什么，我想要一个格式化的字符串，而不是它给我一个答案的转储，这是没有格式化）
以下是带有JSON的HTML / PHP代码：
<!-- Start of Search Wrapper -->
<div class = "imageContainer">

<div class="search-area-wrapper">

<?php
header('Content-type: application/json');
header("Content-Type:application/json");
// Credentials login details and URL connect
$username = "";
$password = "";
$question = $_REQUEST['questionText'];
$url = "https://test.com";
$auth = base64_encode($username . ":" . $password);
//askQuestion();
// ------------------------------------------------------------------------------------------------------------- //
try {
$data = json_encode(array(
'question' => array(
'evidenceRequest' => array('items' => 1),
'formattedAnswer' => true,
'questionText' => $question,
))
);
//$Extract = json_decode($data,true);
// echo $data;
// echo $result;
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Accept: application/json',
'X-synctimeout: 30',
'Authorization: Basic ' . $auth,
'Content-Length: ' . strlen($data))
);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($curl);
} catch(Exception $e) {
echo '<p>There Was an Error Accessing the Webservice!!!</p>';
echo $e->getMessage();
}
?>

运行时提取：
{"question":{"qclasslist":[{"value":"DESCRIPTIVE"},{"value":"FOCUSLESS"},{"value":"DEFINITION"}],"focuslist":[{"value":"brent"}],"latlist":[{"value":"brent"}],"evidencelist":[{},{"value":"0.04949565976858139","text":" To achieve Community Care BLAHBLAHBLAH.........ETC
我真正想要的是字符串返回（实现社区护理BLAHBLAHBLAH ......... ETC）
我改进了代码并注释掉了$ extract，让我很困惑。我还将echo代码更改为print_r（json_decode（$ result））;
运行时提取：
stdClass Object
（ [问题] =＆gt; stdClass对象 （ [qclasslist] =＆gt;排列 （ [0] =＆gt; stdClass对象 （ [value] =＆gt;描述性 ）
[1] => stdClass Object
(
[value] => FOCUSLESS
)
)
[evidencelist] => Array
(
[0] => stdClass Object
(
[value] => 0.48106712102890015
[text] => BLAH BLAH BLAH BLAH
[id] => 001
[title] => What is non-medical prescribing?
[document] => Post/question/djncjabuvas
[copyright] => "URL"
[termsOfUse] => "URL"
我越来越接近我的目标，只需要提取[Title]和[text]字段，这只是一个简单的问答概念。非常感谢您的帮助。我听说格式化答案会有所帮助，但不确定我是否正确宣布它。
答案 0 :(得分：0)
很难判断它是对象还是数组，但尝试将<?php echo json_encode($result, true)?>替换为<?php echo $result->text; ?>或<?php echo $result['text']; ?>。
如果它们不起作用，请尝试将其替换为：<?php var_dump($result); ?>并发布结果。
修改
试试这个：但很难看到对象的结构...... 你真的只需要向我展示一个格式正确的对象，我可以给出明确的答案。
$result->question->evidencelist[0]->text
