 # Bilibili API JVM 调用库
 该项目提供 Bilibili API 的 JVM 调用, 协议来自 Bilibili Android APP 的逆向工程以及截包分析.
 
+# 技术说明
+`BilibiliClient` 类表示一个模拟的客户端, 实例化此类即表示打开了 Bilibili APP.
+
+所有调用从这个类开始, 包括登陆以及访问其他各种 API.
+
+使用协程来实现异步, 由于 [kotlin coroutines](https://kotlinlang.org/docs/reference/coroutines-overview.html) 为编译器实现, 因此并非所有 JVM 语言都能正确调用 `suspend` 方法.
+
+本项目尽可能的兼容其他 JVM 语言和 Android, 不要问, 问就没测试过.
+
+`BilibiliClient` 实例化时会记录一些信息, 例如初始化的事件, 用于更逼真的模拟真实客户端发送的请求. 因此请不要每次都实例化一个新的 `BilibiliClient` 实例, 而应该保存其引用.
+
+一个客户端下各种不同类型的 API (代理类)都是惰性初始化的, 并且只初始化一次, 因此不需要保存 API 的引用, 例如以下代码是被推荐的:
+
+```kotlin
+runBlocking {
+    val bilibiliClient = BilibiliClient().apply {
+        login(username, password)
+    }
+    val myInfo = bilibiliClient.appAPI.myInfo().await()
+    val reply = bilibiliClient.mainAPI.reply(oid = 44154463).await()
+}
+```
+
+如果一个请求的返回内容中的 `code`(code 是 BODY 的内容, 并非 HttpStatus) 不为 0, 将抛出异常 `BilibiliApiException`, 通过以下代码来获取服务器原始返回的 `code`:
+
+```kotlin
+val code = bilibiliApiException.commonResponse.code
+```
+
+一个错误返回的原始 `JSON` 如下所示:
+
+```json
+{
+    "code": -629,
+    "message": "用户名与密码不匹配",
+    "ts": 1550730464
+}
+```
+
+每种不同的 API 在错误时返回的 `code` 丰富多彩(确信), 可能是正数也可能是负数, 可能上万也可能是个位数, 不要问, 问就是你菜.
+
 # 登录和登出
-https://passport.bilibili.com
+(Bilibili oauth2 v3)
 
 登陆和登出均为异步方法, 需要在协程上下文中执行.
 
-    runBlocking {
-        BilibiliClient().run {
-            login(username, password)
-            logout()
-        }
+```kotlin
+runBlocking {
+    BilibiliClient().run {
+        login(username, password)
+        logout()
     }
+}
+```
 
 `login` 方法返回一个 `LoginResponse` 实例, 下次可以直接赋值到没有登陆的 `BilibiliClient` 实例中来恢复登陆状态.
 
-    BilibiliClient().apply {
-        this.loginResponse = loginResponse
-    }
+```kotlin
+BilibiliClient().apply {
+    this.loginResponse = loginResponse
+}
+```
 
-`LoginResponse` 继承 `Serializable`, 可被序列化.
+`LoginResponse` 继承 `Serializable`, 可被序列化(JVM 序列化).
 
-如果登录操作失败, 将抛出 `BilibiliApiException`(只要服务器返回的 code 不为 0 都将抛出异常), 通过以下代码获取服务器返回的 `code`
+可能的错误返回有两种:
 
-    val code = bilibiliApiException.commonResponse.code
+    -629 用户名与密码不匹配
+    -105 验证码错误
 
-在登陆操作中, 如果服务器返回 `-105` 表明本次登陆需要验证码(通常是由于多次错误的登陆尝试导致的), 原始返回如下所示
+如果仅使用用户名与密码进行登陆并且得到了 `-105` 的结果, 那么说明需要验证码(通常是由于多次错误的登陆尝试导致的).
+
+原始返回如下所示
 
     {"ts":1550569982,"code":-105,"data":{"url":"https://passport.bilibili.com/register/verification.html?success=1&gt=b6e5b7fad7ecd37f465838689732e788&challenge=9a67afa4d42ede71a93aeaaa54a4b6fe&ct=1&hash=105af2e7cc6ea829c4a95205f2371dc5"},"message":"验证码错误!"}
 
-自行访问 `commonResponse.data.obj.url.string` 将打开一个极验弹窗, 通过验证码后再次调用登陆接口:
+自行访问 `commonResponse.data.obj.url.string` 打开一个极验弹窗, 完成滑动验证码后再次调用登陆接口:
 
-    login(username, password, challenge, secCode, validate)
+```kotlin
+login(username, password, challenge, secCode, validate)
+```
 
-`challenge` 为本次极验的唯一标识
+`challenge` 为本次极验的唯一标识(在一开始给出的 url 中)
 
 `validate` 为极验返回值
 
 `secCode` 为 `"$validate|jordan"`
 
+(注意, 极验会根据滑动的轨迹来识别人机, 所以要为最终用户打开一个 WebView 来进行真人操作而不能自动完成. 极验最终返回的是一个 jsonp, 里面包含以上三个参数, 详见极验接入文档).
+
 注意, `BilibiliClient` 不能严格保证线程安全, 如果在登出的同时进行登录操作可能引发错误.
 
 登陆后, 可以访问全部 API.
 
-# message
-https://message.bilibili.com
+# 访问 API
+通常的 API 访问是这样的
 
-    BilibiliClient().messageAPI
+```kotlin
+val myInfo = bilibiliClient.appAPI.myInfo().await()
+```
 
-消息通知有关的接口.
-
-# app
-https://app.bilibili.com
-
-    BilibiliClient().appAPI
-
-总站 API. 获取个人信息的完整示例如下:
-
-    runBlocking {
-        val bilibiliClient = BilibiliClient().apply {
-            login(username, password)
-        }
-        val myInfo = bilibiliClient.appAPI.myInfo().await()
-        println(myInfo)
-    }
-
-# av
-https://api.vc.bilibili.com
-
-    BilibiliClient().vcAPI
-
-小视频.
-
-# member
-https://member.bilibili.com
-
-    BilibiliClient().memberAPI
-
-创作中心.
+不要问文档, 用自动补全(心)来感受.
