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

Expo in-app-purchases: ReferenceError: Can#39;t find variable: connectAsync(Expo in-app-purchases:ReferenceError:找不到变量:connectAsync)

问题描述

我正在尝试关注 expo 的 应用内购买文档..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.

I'm trying to follow along with expo's in app purchases documentation.. I have the android developer account and set up my in-app-purchase on that account for the same app. I'm just trying to get started with the documentation and receive an error immediately.

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.

If you look at the documentation, I'm just trying to enter in what's in the first example. I call this function at the beginning of the render method of my app.

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

[Unhandled promise rejection: ReferenceError: Can't find variable: connectAsync]

推荐答案

自从你使用:

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

这意味着您的代码应如下所示:...

That means your code should look like: ...

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