这里开发AndroidAPP，选择Android SDK下载 这个SDK主要是微博分享、微博授权等功能的具体实现的工具，微博提供了这一个方便的SDK方便开发者开发。 而对于微博API的具体调用，SDK中并没有什么帮助，需自己调用，文中开发的APP使用Retrofit + Rxjava来实现。 创建应用完成后如图： 应用注册成功后，会生成对应的appkey和appsecret值。另外需要设置的值有授权回调页。 授权回调页默认设置为：https://api.weibo.com/oauth2/default.html 二 集成SDKAS中构建Android APP工程，集成微博SDK api 'com.sina.weibo.sdk:core:2.0.3:openDefaultRelease@aar' 三 授权 private fun launchScope() { if (this.isFinishing) { return } val mAccessToken = AccessTokenKeeper.readAccessToken(this); if (mAccessToken.isSessionValid) { BlogApplication.mAccessToken = mAccessToken launchMain() return } getToken() } private fun getToken() { mSsoHandler = SsoHandler(this) mSsoHandler.authorize(object : WbAuthListener { override fun onSuccess(token: Oauth2AccessToken?) { LogUtil.i(token?.toString()) val isValid = token?.isSessionValid if (isValid == true) { BlogApplication.mAccessToken = token AccessTokenKeeper.writeAccessToken(this@LoginActivity, token) launchMain() } } override fun onFailure(p0: WbConnectErrorMessage?) { LogUtil.i("err code:" + p0?.errorCode + ", err msg:" + p0?.errorMessage) UiUtil.toast(this@LoginActivity, "授权失败，请重试") } override fun cancel() { LogUtil.i("on cancel.") UiUtil.toast(this@LoginActivity, "授权已取消") } }) } private fun launchMain() { val intent = Intent(this, MainActivity::class.java) startActivity(intent) finish() } override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data) mSsoHandler.authorizeCallBack(requestCode, resultCode, data) }微博授权过程，以上代码即可实现。 以上授权成功后，AccessTokenKeeper类 会获取到四个值： private static final String KEY_UID = "uid"; private static final String KEY_ACCESS_TOKEN = "access_token"; private static final String KEY_EXPIRES_IN = "expires_in"; private static final String KEY_REFRESH_TOKEN = "refresh_token";uid、token、expires_in、refresh_token 这四个值其中token和uid尤为重要，其他不重要。授权过程中需要用户在登录页输入用户名和密码，但是APP是获取不到这些信息的，这些信息的页面不受APP控制，由微博登录页显示获取，然后，微博根据用户名和密码返回给APP以上四个值，这样一来APP与用户密码信息隔离，这就是auth2.0认证的大致过程了 四 调用微博API interface WeiboRequest { @GET("https://api.weibo.com/2/statuses/home_timeline.json") fun getStatusesHomeTimeLineMore(@Query("since_id") since_id: String, @Query("count") count: Int): Observable @GET("https://api.weibo.com/2/statuses/home_timeline.json") fun getStatusesHomeTimeLineRefresh(@Query("max_id") max_id: String, @Query("count") count: Int): Observable @GET("https://api.weibo.com/2/short_url/share/counts.json") fun getShortUrlExpand(@Query("url_short") url_short: String): Observable // 必须是自己发出的微博 @GET("https://api.weibo.com/2/statuses/show.json") fun getDetailInfo(@Query("id") id: String): Observable @GET("https://api.weibo.com/2/comments/show.json") fun getComments(@Query("id") id: String, @Query("since_id") since_id: String, @Query("max_id") max_id: String): Observable @GET("https://api.weibo.com/2/users/show.json") fun getUserInfo(@Query("uid") uid: String, @Query("screen_name") screenName: String): Observable @GET("https://api.weibo.com/2/friendships/friends.json") fun getFollowList(@Query("uid") uid: String, @Query("cursor") cursor: Long): Observable @GET("https://api.weibo.com/2/friendships/followers.json") fun getFollowerList(@Query("uid") uid: String, @Query("cursor") cursor: Long): Observable @GET("https://api.weibo.com/2/statuses/public_timeline.json") fun getPublicTimeLine(@Query("page") page: Long): Observable }以上是APP中用到的微博的一部分API，网络请求使用Retrofit+Rxjava来实现的 请求关注好友的微博列表，代码如下： override fun getStatusesHomeLineLoad() { RetrofitClient.instance.create(WeiboRequest::class.java) .getStatusesHomeTimeLineMore(sinceId, COUNT) .subscribeOn(Schedulers.newThread()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(object : AbstractObserver() { override fun onSuc(t: StatusesResponse) { LogUtil.i("statuses response :${t}") iView?.setStatuses(t.statuses) } override fun onFail(e: Throwable) { } }) }以上代码获取微博列表，返回json信息，微博对象如下： class Statuses: Serializable { var visible: Visible? = null var created_at: String? = null var id: Long = 0 var idstr: String? = null var mid: String? = null var can_edit: Boolean = false var version: Int = 0 var show_additional_indication: Int = 0 var text: String? = null var textLength: Int = 0 var source_allowclick: Int = 0 var source_type: Int = 0 var source: String? = null var favorited: Boolean = false var truncated: Boolean = false var in_reply_to_status_id: String? = null var in_reply_to_user_id: String? = null var in_reply_to_screen_name: String? = null var pic_urls: List? = null var thumbnail_pic: String? = null var bmiddle_pic: String? = null var original_pic: String? = null var geo: Geo? = null var is_paid: Boolean = false var mblog_vip_type: Int = 0 var user: User? = null var retweeted_status: Statuses? = null var annotations: List? = null var reposts_count: Int = 0 var comments_count: Int = 0 var attitudes_count: Int = 0 var pending_approval_count: Int = 0 var isLongText: Boolean = false var reward_exhibition_type: Int = 0 var hide_flag: Int = 0 var mlevel: Int = 0 var biz_feature: Long = 0 var expire_time: Long = 0 var page_type: Int = 0 var hasActionTypeCard: Int = 0 var darwin_tags: List? = null var hot_weibo_tags: List? = null var text_tag_tips: List? = null var mblogtype: Int = 0 var userType: Int = 0 var extend_info: ExtendInfo? = null var more_info_type: Int = 0 var cardid: String? = null var number_display_strategy: NumberDisplayStrategy? = null var positive_recom_flag: Int = 0 var content_auth: Int = 0 var gif_ids: String? = null var is_show_bulletin: Int = 0 var comment_manage_info: CommentManageInfo? = null var pic_num: Int = 0 } 五 UI展示获取微博列表后，UI展示： 具体UI描述： 头像名字微博发布时间微博内容微博图片转发数评论数点赞数转发微博内容等
