所以我正在测试变量是否返回指定用户的屏幕名称 tweets 的 JSON 数据.. 但它没有返回任何内容，我使用了正确的 get 方法.. 我哪里出错了.. 下面是代码..

 <?php
$url= "http://api.twitter.com/1/statuses/user_timeline.json?screen_name=agasaro&count=5";
$results = json_decode(file_get_contents($url));
var_dump($results);

VAR_DUMP 返回这个

 Warning: file_get_contents(http://api.twitter.com/1/statuses/user_timeline.json?screen_name=agasaro&count=5) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in

好吧，您从未将该请求发送到 twitter 服务器。您所做的只是创建了一个 url 字符串，然后使用json_decode了相同的字符串。没有调用 API 函数，因此可以返回一些数据。

在您的浏览器中转到您创建的 url 字符串。您将获得 JSON 输出。

您必须使用 API 函数并将此 url 传递给该函数，以便它返回其他用于curl手动向该 url 发出请求并获取数据然后json_decode它的东西。

编辑：使用已编辑的问题，我无法重现该错误。它在这里工作正常。看到这个输出。

注意：检查链接 file_get_contents throws 400 Bad Request error PHP & https://dev.twitter.com/discussions/678

可能您已经达到了当天的 api 限制，这就是他们阻止您并向您发送 400 响应的原因。
