第六講 smart qq C#開發總結

smart qqC#開發總結：

整個開發下來其實一點都不是很難，從一開始二維碼 獲取到最終的收發消息，基本上都是模擬瀏覽器的操做。都是基於http通信。一下就是 本次新手學習http協議的最關鍵的一個類

因此總結下來基本上只要是懂得一點http協議，基本上網頁版的程序，咱們均可以自由的轉換成圖形桌面版，從而根據本身自身業務進行開發。

其次本人接觸過 最多的就是淘寶客，淘寶天貓京東店數據，固然這些都是官方api的。kaola jd tianmao 等購物網站的分類，商品數據爬取分析（這些都是工做須要）。

第一次發新手教程不少可能看的不是很明白，不過有源碼。能夠根據源碼的註釋進行學習。其中最關鍵的是json的解析了。由於本身也是新手，因此不少都是要查一下資料才明白的。但願這幾講能給一些學習http協議的新手一些啓示（我也是新手，說錯勿怪。）

接下來就是作個圖形界面的smart qq機器人。
