用curl命令行访问twitter的public timeline
文章参考:https://dev.twitter.com/discussions/14460
首先要有twitter帐号，去注册一个，登录
然后去下面的网址创建一个自己的app
https://dev.twitter.com/apps
创建完后，选择Detail tab，点击“Create my access token" 按钮。
然后再去OAuth Tool tab.
输入Request URL:
https://api.twitter.com/1.1/statuses/user_timeline.json
输入Query
screen_name=twitterapi
点击"See OAuth signature for this request"
然后就看到OAuth Signing Results，有推荐的curl命令行，
运行一下：(有些为了保密用...代替了）
curl --get 'https://api.twitter.com/1.1/statuses/user_timeline.json' --data 'screen_name=twitterapi' --header 'Authorization: OAuth oauth_consumer_key="...", oauth_nonce="...", oauth_signature="...", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1389625082", oauth_token="...", oauth_version="1.0"' --verbose
看到一堆信息输出，这里只展示片段：
