ios - 无法通过 iOS 11.4.1 (AWS-IOS-SDK-2.6.24) 将文件上传到 S3 存储桶

问题描述

从 iOS 11.4.1 设备上传 AWS S3 存储桶（使用 AWS-IOS-SDK-2.6.24）上的文件时遇到问题。相同的代码适用于 iOS 9.xx

大多数情况下我收到超时错误：

我正在关注 AWS 文档，我仅从 AWS 文档中收集了所有必需的详细信息。

我已经配置了我的info.plist并将awrconfiguration.json添加到我的项目中。

我在 AppDelegate 类中提到了凭据：

AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc]
                                                          initWithRegionType:AWSRegionAPSouth1
                                                          identityPoolId:@"ap-south-1:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”];


    AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionAPSouth1
                                                                         credentialsProvider:credentialsProvider];
    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;

我无法理解我在这里做错了什么，因为代码在旧版本的 iOS 中运行良好。

我的另一个问题是：如果我们真的需要在 AppDelegate 类中提供凭据，那么为什么我们需要配置 info.plist 或者为什么需要将 awsconfiguration.json 文件复制到我们的项目中。从 info.plist 读取凭证或以编程方式读取 awsconfiguration 文件的方法是什么，而不在 AppDelegate.m 文件中定义凭证？

解决方案

这是部分答案。

你好，

首先，要消除混乱。你只需要一个：

  • awsconfiguration.json
  • Info.plist
  • AppDelegate（或其他地方）中基于代码的凭据

其次，要从 - 或awsconfiguration.json-访问配置，Info.plist您可以构造：

AWSS3TransferUtility *transferUtility = [AWSS3TransferUtility defaultS3TransferUtility];

您可以只尝试基于代码的方法并在我进一步调试时在这里回复吗？
