Twitter API 1.1的問題 - 使用PHP的應用程序唯一身份驗證響應

Question

我試圖通過連接到twitter API來檢索Twitter數據，並在下面提出一些請求我的代碼，但我沒有收到任何回報......我只是要求不記名令牌併成功接收它。

這是PHP代碼：

$url = "https://api.twitter.com/1.1/statuses/user_timeline.json? 

    count=10&screen_name=twitterapi"; 
$headers = array(
    "GET".$url." HTTP/1.1", 
    "Host: api.twitter.com", 
      "User-Agent: My Twitter App v1.0.23", 
    "Authorization: Bearer ".$bearer_token."", 
    "Content-Type: application/x-www-form-urlencoded;charset=UTF-8", 
); 

$ch = curl_init(); // setup a curl 
curl_setopt($ch, CURLOPT_URL,$url); // set url to send to 
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); // set custom headers 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return output 
$retrievedhtml = curl_exec ($ch); // execute the curl 

print_r($retrievedhtml); 

使用的print_r沒事的時候

顯示在所有和使用的var_dump當我找到「布爾（假）」

什麼可能是任何想法這個錯誤？

問候，

Answer 1

嘗試輸出任何潛在的捲曲的錯誤與

curl_error($ch); 

的curl_exec命令後。這可能會給你一些線索，說明發生了什麼問題。完全空的響應通常指向cURL操作本身出錯的地方。

Answer 2

你的頭是錯誤的...不包括

"GET".$url." HTTP/1.1" 

在你的頭

。

此外，您可以通過

$info = curl_getinfo($ch); 
echo $info["http_code"]; 

200打印出HTTP返回代碼是成功的，在4XX或5XX範圍內的任何手段出事了。

我建立在@kiers在Twitter dev discussion中發現的評論基礎上。希望這可以幫助！

我把一些文件放在github上，名爲「翻轉鳥」。希望這有助於...

我創建了PHP庫，支持純應用程序認證和單用戶OAuth。 https://github.com/vojant/Twitter-php。

使用

$twitter = new \TwitterPhp\RestApi($consumerKey,$consumerSecret); 
$connection = $twitter->connectAsApplication(); 
$data = $connection->get('/statuses/user_timeline',array('screen_name' => 'TechCrunch'));
