完成登录需要用到 oauth2/authorize 接口,其接收以下参数:
- client_id: 所申请的app_key
- response_type: 返回数据类型,值可为code或state,code用于后续获取access_token
- display: 授权页面的终端类型,default指示游览器
- redirect_uri: 授权回调地址,需与开放平台中设置的回调地址一致
参数既可以以POST方式传送,也可以以GET方式发送,如下例子:
https://api.weibo.com/oauth2/authorize?redirect_uri=http://liuxiaofang.sinaapp.com/callback?url=/init-comments&ids=3522096338448283&response_type=code&client_id=622387540&display=default
以上url以人为可读的方式显示,向应用服务器发送前还得经过编码(如使用python中的urllib.quote)。
这里所说的回调地址,通过 应用页面 -> 接口管理 -> 授权设置 进行配置。
正确发送URL后,将进入以下登录界面:
成功登录后,将跳转到我们之前设定的 redirect_uri,并返回 code 值:
http://liuxiaofang.sinaapp.com/callback?url=/init-comments&ids=3522096338448283&code=123456
有了code,我们就可以请求获取access_token,获取 access_token 的接口为 oauth2/access_token,其接收以下参数:
- grant_type: 请求类型,对应与调用 authorize 获得的code,这里值应为 authorization_code
- code: 以上获得的 code 值
- client_id: 所申请的 app_key
- client_secret: 所申请的 app_secret
- redirect_uri: 回调地址,需与开放平台中设置的回调地址一致
https://api.weibo.com/oauth2/access_token
grant_type = authorization_code
client_id = 622387540
client_secret = 123456
redirect_uri = http://liuxiaofang.sinaapp.com/callback?
code = 123456
正确发送URL后,将跳转到类似以下授权页面:
完成授权后,将跳转到之前设定的回调地址,并且从 response 中,我们可以获取到 access_token 和 expires_in 超时值。
有了 access_token,我们终于可以使用 2/comments/show 这类需要事先登录授权的接口了。下面通过GET方式获取指定微博id的评论,获取到的 access_token 放置在请求头中:
https://api.weibo.com/2/comments/show?id=3522885349661782
Authorization: OAuth2 123456
之后新浪服务器将返回评论id、评论文本、评论创建时间、评论作者等信息。
