微信weixin://xxx 分析

經過weixin://來打開微信客戶端：

<a href="weixin://">打開微信</a>
<a href="weixin://dl/business/?ticket=xxx">微信內打開網頁</a>

 協會說明：

微信跳轉入口：

經過反編譯，看到weixin://協議的入口定義爲WXCustomSchemeEntryActivity，那就是瀏覽器訪問以weixin爲scheme的請求時就會打開微信內的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>

內部處理

1.獲取攜帶數據

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;
    }
}

3.進行跳轉

根據url對應的地址，調用微信內的路由組件進行跳轉。
