Question

我按照github readme上的说明操作，将应用程序导入我的AWS Mobile Hub项目，并将我的项目aws-config.js下载到src / assets。当我尝试提供应用程序时，我收到运行时错误：

public partial class MySetup : ContentPage
{
    public MySetup()
    {
        InitializeComponent();

        FacebookSwitch.On = <if Facebook is on>;
        TwitterSwitch.On = <if Twitter is on>;
    }
}

非常感谢任何见解。

编辑：我在app.config.ts代码下面添加了以及我的aws-config.js文件的一部分（省略了包含我的AWS移动中心项目详细信息的顶部的常量声明）

app.config.ts：

Runtime Error:

aws_cognito_region is not defined

AWS-config.js：

import { Injectable } from '@angular/core';

declare var AWS: any;
declare const aws_mobile_analytics_app_id;
declare const aws_cognito_region;
declare const aws_cognito_identity_pool_id;
declare const aws_user_pools_id;
declare const aws_user_pools_web_client_id;
declare const aws_user_files_s3_bucket;

@Injectable()
export class AwsConfig {
  public load() {

    // Expects global const values defined by aws-config.js
    const cfg = {
      "aws_mobile_analytics_app_id": aws_mobile_analytics_app_id,
      "aws_cognito_region": aws_cognito_region,
      "aws_cognito_identity_pool_id": aws_cognito_identity_pool_id,
      "aws_user_pools_id": aws_user_pools_id,
      "aws_user_pools_web_client_id": aws_user_pools_web_client_id,
      "aws_user_files_s3_bucket": aws_user_files_s3_bucket
    };

    AWS.config.customUserAgent = AWS.config.customUserAgent + ' Ionic';

    return cfg;
  }
}

Answer 1

我通过转到aws-config.js并删除定义的每个变量上的单引号来修复此问题。所以如果你有这个：

const 'aws_cognito_region' = 'us-east-1';

更改为：

const aws_cognito_region = 'us-east-1';

您需要使用您的AWS信息（app id，pool id等）配置src / app / app.config。
