Detailed documentation on the AWS S3 binding component

配置

To setup AWS S3 binding create a component of type bindings.aws.s3. See this guide on how to create and apply a binding configuration.

See Authenticating to AWS for information about authentication-related attributes

create

Create file

To perform a create operation, invoke the AWS S3 binding with a POST method and the following JSON body:

注意：默认情况下，会随机生成一个UUID。参见下面所示的支持的元数据设置名称

{
  "operation": "create",
  "data": "YOUR_CONTENT"
}

示例

Save text to a random generated UUID file

Windows
Linux

在Windows上，使用cmd提示符（PowerShell有不同的转义机制）。

curl -d "{ \"operation\": \"create\", \"data\": \"Hello World\" }" http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "Hello World" }' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d "{ \"operation\": \"create\", \"data\": \"Hello World\", \"metadata\": { \"key\": \"my-test-file.txt\" } }" \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "Hello World", "metadata": { "key": "my-test-file.txt" } }' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

Upload a file

To upload a file, pass the file contents as the data payload; you may want to encode this in e.g. Base64 for binary content.

然后你就可以像平常一样上传了：

Windows
Linux

curl -d "{ \"operation\": \"create\", \"data\": \"(YOUR_FILE_CONTENTS)\", \"metadata\": { \"key\": \"my-test-file.jpg\" } }" http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "create", "data": "$(cat my-test-file.jpg)", "metadata": { "key": "my-test-file.jpg" } }' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>
