Question

我正试图通过连接到Twitter API来检索来自Twitter的数据，并在下面提出我的代码请求，但我得不到任何回报......我只是请求了持有人令牌并成功收到了它。

这是PHP中的代码：

    $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print_r时根本没有显示任何内容，使用var_dump时我发现“bool（false）”

对于这可能出错的任何想法？

此致

Answer 1

尝试使用

输出任何潜在的cURL错误

curl_error($ch);

在curl_exec命令之后。这可能会让你知道出了什么问题。完全空的响应通常指向cURL操作本身出错。

Answer 2

您的标题错误...不包括

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

在你的标题中。

此外，您可以通过

打印出HTTP返回码

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

200是成功的，4xx或5xx范围内的任何内容都意味着出了问题。

我是根据@kiers在Twitter dev discussion中找到的评论构建的。希望这有帮助！

我创建了支持仅应用程序身份验证和单用户OAuth的PHP库。 https://github.com/vojant/Twitter-php

<强>用法

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