在上一篇發佈的時候離現在已經過去不少的時間， 這段時間也一直處理這個問題， 最終解決了它，因爲自己內容的原因，自己也走不了少的彎路，比如增加一些配置問題， coturn在測試網站 是通的，但實際使用的時候是不通的， （具體原因還不瞭解）現在都解決了， 自己之前保存的也亂掉的，寫的有些不好，以後想好會微調本博客
在調試janus的時候，因爲底層是調用底層webrtc的api，包含http， https，websocket, ice連接，dtls連接，等許多傳輸方式，在外網調試的時候經常會遇到黑屏，光有聲音沒有畫面等一系列問題， 但是遇到這些情況到底是什麼原因引起的呢， 如果要根據日誌， 其具體情況也是模糊不清的， 一些中間變量到底缺少什麼呢， 這時就需要admin api， 這工具實在是太有用的。
瀏覽器也有一些中間情況的調試 比如，chrome瀏覽器 chrome://webrtc-internals firfox瀏覽器 about:webrtc， 但是別的端也沒得工具了， 比如手機， 前段時間調試videocall功能， 手機端一直調試不通， 在瘋狂找尋解決方案的時候，看到了admin api， 也利用這個工具解決的自己的問題。

這是一個成功的handles， 這裏面重要的是
1 sdps， 這裏包含一個offer 和一個answer的sdp， 可以利用這個sdp查看一些連接的基本內容。
2 components， 這裏包含 candidates的信息， dtls的信息。而components裏的內容是我主要利用的內容。
- local-candidates 本地候選者，
- remote-candidates 遠端候選者
- selected-pair 連接
- dtls dtls連接狀態

state的狀態是"disconnected"， 這意味着根本沒有啓動連接狀態檢查， dtls的數據也是爲空的， 這是什麼原因引起的呢，這隻有本地候選者， 沒有遠端候選者，這說明客戶端沒有上報信息到janus，janus沒有信息所以建立不了連接。這時檢查offersdp及回覆的answer有什麼問題。

這裏的遠端候選者的ip是一個本地ip， 不是一個公網ip， 這說明客戶端上報的時候沒有上報自己的公網ip，在做連接的時候兩臺機器不在一個內網環境的話，光本地ip是連接不通的， 引起的原因如下 ：
1.缺少足夠的數據來使ICE連接成功
2.網絡問題， 防火牆或者別的原因引起的ICE連接不成功
3.客戶端沒有配置STUN服務器，
4.客戶端配置了STUN服務器，但STUN服務器有問題或者連接STUN有問題
說明： janus服務需要ICE連接相互流轉media數據的， 所以janus服務端要配置一個STUN， 而客戶端也需要各自配置STUN服務，缺少一個都會導致不通。

這是ICE是成功的， dtls-state也是連接的， 但是數據流還是沒有， 這可能 就是插件配置裏的問題，可能是沒有訂閱或者 其他 的問題導致的。

ice連接失敗，創建 selected-pair失敗是ice_lite janus在janus配置支持ICE_LITE的時候報的錯， 這導致的原因是STUN服務和janus配置不一致

這個是janus full_trickle時，STUN服務跟janus不一致導致的。這些都 是ICE連接的失敗。
