Question

在我的Android应用程序中，我希望用户能够输入推特用户名，然后在输入的用户名页面上启动推特应用程序。我做了一些研究，发现从另一个应用程序打开twitter应用程序所需的链接是twitter：// user？user_id = id_num我想知道是否有办法从推特用户名获取用户的推特ID在Android中，所以我可以实现这一点。非常感谢任何帮助，谢谢。

您应该仔细阅读Twitter API，特别是关于user lookups的部分编辑：链接已更新为当前的Twitter API文档，但答案仍然是针对API v1.1时的问题。

该特定请求具有可通过id或screen_name搜索的可选字段，并将返回可以为用户ID解析的匹配列表。因此，您可以通过screen_name进行搜索并阅读响应以获取ID。

您正在寻找的请求是：

GET https://api.twitter.com/1/users/lookup.json?screen_name=somename

API示例中提供的响应是（是）：

因此，您可以通过解析“id”字段的JSON响应来从结果中访问id。

但请注意，返回的是JSON结果数组，而不仅仅是一个明确的答案。你需要自己解决哪个是正确的（订单不能保证，所以不要假设第一个条目最有可能）。

另外值得注意的是，尽管记录为返回'id'和整数值，但当前首选的id用法是提供'id_str'和整数的字符串表示。这是由于各种平台处理和限制整数的方式不一致。因此，即使您收到“id”，也应该使用“id_str”进行未来的互动。
