Google API - 使用PHP的URL Shortener

Question

我的代码如下.URL缩短服务有效,但是当我插入我的时,它不会$POST.有谁知道如何修复这个我看代码？

// This is the URL you want to shorten
$longUrl = 'http://www.mysite.com/XXXXX/XX/$_POST['qrname']';

// Get API key from : http://code.google.com/apis/console/
$apiKey = 'MyAPIKey';

$postData = array('longUrl' => $longUrl, 'key' => $apiKey);
$jsonData = json_encode($postData);

$curlObj = curl_init();

curl_setopt($curlObj, CURLOPT_URL, 'https://www.googleapis.com/urlshortener/v1/url');
curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curlObj, CURLOPT_HEADER, 0);
curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
curl_setopt($curlObj, CURLOPT_POST, 1);
curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);

$response = curl_exec($curlObj);

// Change the response json string to object
$json = json_decode($response);

curl_close($curlObj);

echo 'Shortened URL is: '.$json->id;

Answer 1

请尝试以下方式

$longUrl = 'http://www.mysite.com/XXXXX/XX/'.$_POST['qrname'];

以上将有效.

$longUrl = "http://www.xxxxxxx.com";
    $postData = array('longUrl' => $longUrl);

    $response = curl_exec($curlObj);

    $json = json_decode($response);

//    print_r($json);exit;
    //6
    curl_close($curlObj);

    //7
    if(isset($json->error)){
        echo $json->error->message;
    }else{
        echo $json->id;
    }   

Answer 3

你在单引号之间传递php变量,所以它不会被解析.在双引号之间传递它

$longUrl = "http://www.mysite.com/XXXXX/XX/$_POST['qrname']";

或者像这样结合

$longUrl = 'http://www.mysite.com/XXXXX/XX/'.$_POST['qrname'];

Answer 4

你有一把钥匙,但你没有正确使用它

您应该将其附加到网址,不要在帖子中发送密钥

https://www.googleapis.com/urlshortener/v1/url?key='.$apiKey
