Question

我知道这是一个非常愚蠢的问题，但我仍然要问这个因为它不起作用。

我正在调用API ...

    $service_url = 'http://localhost:8888/ffmobile/signup';
    $curl = curl_init($service_url);
    $curl_post_data = array('email' => $this->params()->fromPost('email'), 'password' => $this->params()->fromPost('password'), 'userName' => $this->params()->fromPost('uname'));
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $curl_response = curl_exec($curl);
    curl_close($curl);

当我打印$ curl_response时，输出如下

{"Error":{"name":"Email Unavailable","message":"Email is already taken. Please choose different email.","code":202},"status":"False","requestId":null}

输出是正确的，但是当我使用它时如下......

$response = json_decode($curl_response, TRUE);

我正在打印没有打印任何内容的$响应。

可能是什么问题？

有人能帮助我吗？

Answer 1

试试这个例子：

<?php

$json = '{
    "Error": {
        "name": "Email Unavailable",
        "message": "Email is already taken. Please choose different email.",
        "code": 202
    },
    "status": "False",
    "requestId": null
}';

$info = json_decode($json, true);

echo "Error - Name: {$info['Error']['name']}<br>"; 
echo "Error - Message: {$info['Error']['message']}<br>"; 
echo "Error - Code: {$info['Error']['code']}<br>"; 
echo "Status: {$info['status']}<br>"; 
echo "RequestId: {$info['requestId']}<br>"; 
?>

输出：

Error - Name: Email Unavailable
Error - Message: Email is already taken. Please choose different email.
Error - Code: 202
Status: False
RequestId:

要检查解码是否正常，您可以运行此代码：

$json = '{"Error":{"name":"Email Unavailable","message":"Email is already taken. Please choose different email.","code":202},"status":"False","requestId":null}';     
print_r(json_decode($json, TRUE));

如果你的代码中的isres是一个错误解码，json_decode将返回null，你可以检查这个，然后运行json_last_error()

可能存在卷曲错误。如果是这种情况，curl_exec将返回false。还要检查json_decode错误。

来源：http://php.net/manual/en/function.curl-error.php

$service_url = 'http://localhost:8888/ffmobile/signup';
$curl = curl_init($service_url);
$curl_post_data = array('email' => $this->params()->fromPost('email'), 'password' => $this->params()->fromPost('password'), 'userName' => $this->params()->fromPost('uname'));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$curl_response = curl_exec($curl);
if($curl_response === false)
{
    echo 'Curl error: ' . curl_error($curl);
}
else
{
    $response = json_decode($curl_response, TRUE);
    curl_close($curl);
    if( is_null($response) ) {
        echo 'json_decode error: ' . json_last_error();
    } else {
        // everything OK, do something with the response
    }
}

JSON_DECODE（）无法正常工作？
