通過微信的掃一掃去下載衅斩，會出現(xiàn)白屏的情況襟沮，可能是因為安全性的考慮或者其他什么原因，目前已經(jīng)無法通過微信的掃一掃去下載apk了跪腹。
根據(jù)網(wǎng)友們提供的思路褂删，本文整理了三種方案。
1冲茸、申請騰訊開放平臺開發(fā)者
具體流程可以去訪問http://open.qq.com/屯阀，大概的意思是需要將apk提交到騰訊開放平臺的里面，每個apk應(yīng)該會自動生成一個二維碼轴术，每年支付一定的費用蹲盘，然后在微信里面掃一下這個二維碼，這個時候也需要先安裝一個手機(jī)應(yīng)用寶膳音，才能進(jìn)行 apk的安裝。
對于這種方案铃诬，只能用一種很流行的話說:”很任性”祭陷。
2苍凛、重定向
這種方法對于一些已經(jīng)發(fā)布出去的二維碼比較有用，也是目前比較普遍的做法兵志。不可能因為微信不能直接下載了醇蝴，就得把所有的已經(jīng)流出去的二維碼重新生成吧？
2.1判斷瀏覽器類型
/*首先判斷是否是pc想罕，若是pc訪問則跳轉(zhuǎn)到http://app.ctrip.com/*/
????var u = navigator.userAgent || '';
????var isPC = !/(iphone|ios|android|mini|mobile|mobi|Nokia|Symbian|iPod|iPad|Windows\s+Phone|MQQBrowser|wp7|wp8|UCBrowser7|UCWEB|360\s+Aphone\s+Browser)/i.test(u);
????if (isPC) { location.; }
如果是pc端的話悠栓，那么直接重定向到一個網(wǎng)站
如果是非pc端的話，那么要區(qū)分是android還是apple?
2.2判斷是android還是iOS?
因為我們假設(shè)iOS的下載必須從蘋果的appstore里面下載按价，那么其下載地址有一定的規(guī)律惭适，比如說sourceid等。
可以通過一個正則表達(dá)式來確定楼镐。
var urls = document.location.search, re2 = new RegExp("(\\\?|&)sourceid=([^&]+)(&|$)", "i"), from = urls.match(re2);
????if (from) { sid = from[2]; }
document.location.search
比如一個URL是XXXX?g=1,那么document.location.search的值就是?g=1
2.3重定向到下載地址
window.onload = function () { //修復(fù)圖片偶爾不能加載
????????var salesLocal = localStorage.getItem("SALESOBJ") ? JSON.parse(localStorage.getItem("SALESOBJ")) : null;
????????var appUrl = salesLocal && salesLocal.data && salesLocal.data.appurl ? salesLocal.data.appurl : "";
????????if (!isPC && !iswx) {
????????????if(appUrl){
????????????????location.href = appUrl;
????????????}else if(sid){
????????????????location.href = "/m/" + sid;
????????????}
????????}
????}

3凄杯、工具 旋風(fēng)微跳demo演示地址
旋風(fēng)微跳是一款基于微信后端開發(fā)了一款微信營銷下載推廣助手，使用了本插件生成的鏈接秉宿，用戶在微信任意環(huán)境下點擊鏈接或者掃描二維碼戒突，可以實現(xiàn)直接跳轉(zhuǎn)手機(jī)默認(rèn)瀏覽器并打開指定網(wǎng)頁。
1描睦、打開 旋風(fēng)微跳 網(wǎng)址
2膊存、準(zhǔn)備好我們的推廣鏈接：實例如：www.baidu.com ?在輸入框填寫你的下載鏈接，填寫完畢后酌摇。點擊生成按鈕
3膝舅、點擊生成之后，就會看到底部生成了自己的推廣二維碼以及短網(wǎng)址鏈接地址窑多。
至此仍稀，我們已經(jīng)生成了APP推廣鏈接的宣傳二維碼和鏈接。 我們就可以直接用微信掃描二維碼在微信中分享和宣傳引流了埂息。這樣我們能夠極大的提高自己的APP在微信中的推廣轉(zhuǎn)化率技潘。解決掉了微信中下載鏈接被屏蔽等問題。充分利用微信的用戶群體來宣傳引流千康。
