通过weixin://来打开微信客户端：
<a href="weixin://">打开微信</a> <a href="weixin://dl/business/?ticket=xxx">微信内打开网页</a>
协会说明：
微信跳转入口：
通过反编译，看到weixin://协议的入口定义为WXCustomSchemeEntryActivity，那就是浏览器访问以weixin为scheme的请求时就会打开微信内的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>
内部处理
1.获取携带数据
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)); }
2.判断是否合法
// 校验是否非法 if (data != null) { String uri = data.getScheme() + "://" + data.getHost() + data.getPath(); // qby详情看问末附录 if (!qby.containsKey(uri) && !data.toString().startsWith("weixin://dl/business")) { return; } }
3.进行跳转
根据url对应的地址，调用微信内的路由组件进行跳转。
