這篇文章主要介紹“android微信公眾號(hào)開(kāi)發(fā)實(shí)例分析”，在日常操作中，相信很多人在android微信公眾號(hào)開(kāi)發(fā)實(shí)例分析問(wèn)題上存在疑惑，小編查閱了各式資料，整理出簡(jiǎn)單好用的操作方法，希望對(duì)大家解答”android微信公眾號(hào)開(kāi)發(fā)實(shí)例分析”的疑惑有所幫助！接下來(lái)，請(qǐng)跟著小編一起來(lái)學(xué)習(xí)吧！
開(kāi)發(fā)前說(shuō)明：
我們需要用到 StreamReader
所以需要引用：using System.IO;
上面講了一些微信給我們的規(guī)則
我們現(xiàn)在要用這些規(guī)則獲取我們想要的東西。
第一步：獲取那串 XML 這個(gè)是最重要的，因?yàn)闆](méi)這個(gè)XML，我們就相當(dāng)于啥都沒(méi)有。（我們的信息來(lái)源就是這個(gè)XML）
這里我使用 StreamReader 來(lái)獲取 Request.Body
因?yàn)閄ML主要是 Request.Body 里面的
//聲明一個(gè)XML方便調(diào)用 string xml=""; //獲取我們的流 var reader = new StreamReader(Request.Body); //把流里面的讀取出來(lái)，就是我們這串XML了。 var contentFromBody = reader.ReadToEnd(); //再保存進(jìn)我們的這個(gè)字符串里，方便后期使用 xml = contentFromBody;
我們讀取XML中的信息，并將其轉(zhuǎn)成我們的微信信息對(duì)象。
這里呢。我借用了一位大佬的代碼：

}有了這兩個(gè)類(lèi)，我們的東西就好開(kāi)展了，如果大家有發(fā)現(xiàn)報(bào)錯(cuò)的話(huà)，是因?yàn)閟tring擴(kuò)展類(lèi)的問(wèn)題。需要的留下郵箱，這個(gè)東西太長(zhǎng)了。不好發(fā)，不過(guò)大家應(yīng)該都看的懂，自己寫(xiě)一套也好。
使用上面第二個(gè)類(lèi)中的，這個(gè)方法，進(jìn)行轉(zhuǎn)換 ： XmlToMessageFromWeiXin
得到我們 msg 對(duì)象
我們這個(gè)對(duì)象里面有msgtype，這個(gè)type枚舉呢，就對(duì)應(yīng)了各個(gè)事件。
我們寫(xiě)個(gè)switch就能將他們分開(kāi)了。不同事件進(jìn)入不同分支處理。
