如何快速读取 Branch.io 中的 URL 参数 link

Question

这应该很简单，但无法正常工作...

我有一个 Branch.io 的 Web SDK 实现，就像在 https://help.branch.io/developers-hub/docs/web-full-reference 中一样。我创建了一个快速 link，当用户单击快速 link 时，可以在 JavaScript 中访问 Branch.init() 及其回调 window.branch。但是，我看不到必须在单击时发送的查询参数。

假设我的快速 link 是： https://appname.test-app.link/LinkCode?customName=customValue

如何访问 JavaScript 中的 customName 和 customValue？我试过 window.branch 但仍然看不到参数。

提前致谢！

Answer 1

我可以告诉你我是怎么做到的。我不确定这是否是 best/correct 方式，但它对我有用。

有两个部分可以让它工作：a) 将数据导入快速 link，以及 b) 从快速 link.

中读取数据

如何将 customName=customValue 添加到快速 link？它不像将 ?customName=customValue 添加到快速 link url 那样简单（这也是我尝试的第一件事）。

相反，您可以使用 Branch 仪表板或 Branch API。

无论哪种方式，您都需要向 quick link 的数据属性添加字段，这是 quick [=44] 的“Link 数据”部分=] 在仪表板中。

建议将带有所需查询参数的 url 添加到 $canonical_url 字段。但是，我发现使用 $custom_meta_tags 字段更容易，它接受序列化的 JSON 字符串。

docs 中有 easy-to-miss 行：

The init function returns a data object where you can read the link the user was referred by.

所以这对我有用：

branch.init(key, {}, (error, data) => {
  if (error !== null) {
    // handle error
  } else {
    if (data?.data_parsed?.$custom_meta_tags) {
      const tags = data.data_parsed.$custom_meta_tags
      // Do what you want with the data
    }
  }
}

Answer 2

对于 React JS 应用程序，解决方案似乎有点复杂。我的应用程序嵌入在 Cordova 框架中。下面的解决方案可让您捕获由 server-side 代码动态生成的 Branch.io link。

要遵循的步骤：

在代码初始化时初始化分支link接收的能力。
随时在代码中检索分支 link 的数据。

解决方案：

您需要调用下面的插件并配置您的分支调用。

<plugin name="branch-cordova-sdk" spec="^4.0.0" />
<branch-config>
    <branch-key value=YOUR_VALUE />
    <uri-scheme value=YOUR_VALUE" />
    <link-domain value=YOUR_VALUE /> <!-- Required app.link domain -->
    <link-domain value=YOUR_VALUE /> <!-- Required alternate.app.link domain -->
    <link-domain value=YOUR_VALUE />  <!-- Required test.app.link domain -->
    <link-domain value=YOUR_VALUE />  <!-- Required alternate.test.app.link domain -->
    <ios-team-release value=YOUR_VALUE />
</branch-config>

使用类似于下面的函数。它会捕获分支信息并为您解析。解析后，您可以访问您需要的值并调用您可能需要的函数。

async function handleBranchIO() {

    let THE_VALUE_YOU_WANT = null;
    console.log('Inside branch function')
    // This function is the section 'Read deep link' from https://help.branch.io/developers-hub/docs/cordova-phonegap-ionic

    if (window.Branch !== undefined) {
        // Branch initialization within your deviceready and resume
        await window.Branch.initSession().then(async function success(res) {
            // console.log('Branch already initialized')

            if (res["+clicked_branch_link"]) {
                // Alert message to check the Branch.io's deepnlink information.
                // alert("Open app with a Branch deep link: " + JSON.stringify(res));
                THE_VALUE_YOU_WANT = await res.THE_VALUE_YOU_WANT
                console.log(THE_VALUE_YOU_WANT)
                THE_FUNCTION_YOU_WANT_TO_EXECUTE(THE_VALUE_YOU_WANT)
                // Branch quick link: https://cordova.app.link/uJcOH1IFpM
                // Branch web link: https://cordova-alternate.app.link/uJcOH1IFpM
