本地存储绑定规范

To set up the Local Storage binding, create a component of type . See this guide on how to create and apply a binding configuration.

字段名为 ttlInSeconds。

create :
get : Get file
list :
delete : Delete file

To perform a create file operation, invoke the Local Storage binding with a POST method and the following JSON body:

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

示例

Save text to a random generated UUID file

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>

Save text to a specific file

Linux

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

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

Save a binary file

To upload a file, encode it as Base64. The binding should automatically detect the Base64 encoding.

Windows

curl -d '{ "operation": "create", "data": "YOUR_BASE_64_CONTENT", "metadata": { "fileName": "my-test-file.jpg" } }' \

响应

响应体将包含以下JSON：

{
   "fileName": "<filename>"
}

To perform a get file operation, invoke the Local Storage binding with a POST method and the following JSON body:

{
  "operation": "get",
  "metadata": {
    "fileName": "myfile"
  }
}

Example

Windows

curl -d '{ \"operation\": \"get\", \"metadata\": { \"fileName\": \"myfile\" }}' http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "get", "metadata": { "fileName": "myfile" }}' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

响应

The response body contains the value stored in the file.

If you only want to list the files beneath a particular directory below the rootPath, specify the relative directory name as the fileName in the metadata.

{
  "operation": "list",
  }
}

Example

Windows

curl -d '{ \"operation\": \"list\", \"metadata\": { \"fileName\": \"my/cool/directory\" }}' http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

curl -d '{ "operation": "list", "metadata": { "fileName": "my/cool/directory" }}' \
      http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

响应

The response is a JSON array of file names.

To perform a delete file operation, invoke the Local Storage binding with a POST method and the following JSON body:

{
  "operation": "delete",
  "metadata": {
    "fileName": "myfile"
  }
}

Example

Windows

curl -d '{ \"operation\": \"delete\", \"metadata\": { \"fileName\": \"myfile\" }}' http://localhost:<dapr-port>/v1.0/bindings/<binding-name>

响应

An HTTP 204 (No Content) and empty body will be returned if successful.

{
    "data": "file content",
    "metadata": {
        "fileName": "filename.txt"
    },
    "operation": "create"
