android - Expo in-app-purchases：ReferenceError：找不到变量：connectAsync

Question

我正在尝试遵循 expo 的应用程序购买文档。. 我有 android 开发者帐户，并在该帐户上为同一个应用程序设置了我的应用程序内购买。我只是想开始使用文档并立即收到错误。

如果您查看文档，我只是想输入第一个示例中的内容。我在我的应用程序的渲染方法的开头调用了这个函数。

import * as InAppPurchases from 'expo-in-app-purchases';
...

const getHistory = async function(){ 
  const history = await connectAsync();
    if (history.responseCode === IAPResponseCode.OK) {
      history.results.forEach(result => {
        console.log(result)
      });
    }
}

我收到这些错误

由于您使用：

import * as InAppPurchases from 'expo-in-app-purchases';

这意味着您的代码应如下所示： ...

const getHistory = async function(){ 
  const history = await InAppPurchases.connectAsync();
    if (history.responseCode === InAppPurchases.IAPResponseCode.OK) {
      history.results.forEach(result => {
        console.log(result)
      });
    }
}
