一般大家都知道可以通過weixin://來打開微信客戶端楞捂，那它的原理是什么呢？
<a href="weixin://">打開微信</a>
<a href="weixin://dl/business/?ticket=xxx">微信內(nèi)打開網(wǎng)頁</a>

微信跳轉(zhuǎn)入口
通過反編譯趋厉，看到weixin://協(xié)議的入口定義為WXCustomSchemeEntryActivity寨闹，那就是瀏覽器訪問以weixin為scheme的請求時就會打開微信內(nèi)的WXCustomSchemeEntryActivity。
<activity
android:name="com.tencent.mm.plugin.base.stub.WXCustomSchemeEntryActivity"
android:configChanges="keyboardHidden|orientation|screenSize"
android:excludeFromRecents="true"
android:exported="true"
android:launchMode="singleTop"
android:taskAffinity=".wxpayentry"
android:theme="@style/mm">
<intent-filter>
<data android:scheme="weixin" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
</intent-filter>
</activity>
內(nèi)部處理
獲取攜帶數(shù)據(jù)
Uri data = getIntent().getData();
if (data != null) {
String scheme = data.getScheme();
String host = data.getHost();
String query = data.getQuery();
Log.i("MicroMsg.WXCustomSchemeEntryActivity", String.format("uri is %s,scheme is %s, host is %s, query is %s", data.toString(), scheme, host, query));
}
判斷是否合法
// 校驗是否非法
if (data != null) {
String uri = data.getScheme() + "://" + data.getHost() + data.getPath();
// qby詳情看問末附錄
if (!qby.containsKey(uri) && !data.toString().startsWith("weixin://dl/business")) {
return;
}
}
進行跳轉(zhuǎn)
根據(jù)url對應(yīng)的地址君账，調(diào)用微信內(nèi)的路由組件進行跳轉(zhuǎn)繁堡。
