图片上传Amazon S3 android SDK 2.0 [英] Image upload amazon s3 android SDK 2.0

问题描述

我想将图像上传到android中的amazon s3存储桶。
我没有收到任何错误，但是它没有用，有人可以帮助我吗？
我找不到任何好的示例或问题。

I want to upload an image to an amazon s3 bucket in android. I don't get any errors but it's just not working can anybody help me? I can't find any good examples or questions about this.

我将图像分配给文件images3

I assign a image to 'File images3'

images3 = new File(uri.getPath());

public void addEventToDB(){

        Thread thread = new Thread()
        {
            @Override
            public void run() {
                try {
                    CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
                            getActivity().getApplicationContext(), // get the context for the current activity
                            "...",
                            "us-east-1:...",
                            "arn:aws:iam::...:role/Cognito_WitpaAuth_DefaultRole",
                            "arn:aws:iam::...:role/Cognito_WitpaAuth_DefaultRole",
                            Regions.US_EAST_1
                    );

                    String bucket_name = "witpa";
                    String key = "images.jpeg";

                    TransferManager transferManager = new TransferManager(credentialsProvider);
                    transferManager.upload(bucket_name, key, images3);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        };

        thread.start();

    }

我创建了我的存储桶，并设置了每个人的权限可以写和读。

I created my bucket, in the permissions I set that everyone can write and read.

在Amazon Cognito中，我只是将所有内容保留为默认值。

In amazon cognito I just left everything as default.

任何人都知道我该怎么做

Anybody knows how I can get this to work?

推荐答案

尝试一下。由于我遇到了与您同样的问题。

Try this one. Since i had the same issue that you faced.

我已使用以下代码修复了问题。

I have fixed by using the below code.

ObjectMetadata metadata = new ObjectMetadata();
metadata.setContentEncoding("UTF-8");
size = inputStream.available();
metadata.setContentLength(size);
TransferManager transferManager = new TransferManager(credentialsProvider);
Upload upload = transferManager.upload(bucket_name, key, images3, metadata);
upload.waitForCompletion();
