About File and Folder Operations

For all the API calls, you must first obtain an access token. The access token is used to create an instance of the SDK which allows you to access the SDk methods.

Code Sample

SdkClient.new(session[:access_token])

Copy

file_copy creates a copy of a file or a folder. Any missing folder in the target path will be created.

NOTE:
You cannot perform the file_copy operation on a virutal folder.

Required Parameters

src – Path of the source file to be renamed.
target – Path of the file with the updated name.
safe:
- If set to true, name conflicts are resolved according to the value of the conflictsolve parameter.
- If set to false, the operation overwrites an existing file or folder of the same name. This is the default.
conflictsolve – Defines how name conflicts are resolved if the safe parameter is set to true:
- Set to copy to write a file to the destination folder with a non-conflicting name.
- If not set, the operation is rolled back and operation returns 409 Conflict.
override – Specifies what happens if a file of the same name exists at the target path and the safe parameter is not set:
- Set to overwrite to treat the copied file as completely new.
- Set to modify to treat the new file as a modification of the old one.
- If not set:
  - If the existing file has a deleted attribute set to true, the file is overwritten.
  - If the old file’s deleted attribute is false or not set, the file is modified.

Note: safe, conflictsolve, and override are optional parameters in the request object to copy a file or a folder.

Parameter request format:

{
	"src": "string",
	"target": "string",
	"safe": false,
	"conflictsolve": "string",
	"override": "string"
}

Code Sample

begin
  
    entry = client.file_copy(src,target,safe,conflictsolve,override)
  rescue SdkAuthError => e
    session.delete(:access_token)  # An auth error means the access token is probably bad
    logger.info "Sdk auth error: #{e}"
    return html_page "Sdk auth error"
  rescue SdkError => e
    if e.http_response.code == '404'
      return html_page "Path not found: #{h path}"
    else
      logger.info "Sdk API error: #{e}"
      return html_page "Sdk API error  #{e}"
    end

    entry = client.get_file(path)
  rescue SdkAuthError => e
    session.delete(:access_token)  # An auth error means the access token is probably bad

File Upload

Chunked and Non-Chunked File Upload

Chunked file uploads allow you to break a large file into small chunks, and then send these pieces to the upload server one-by-one. If an upload were to fail, your app would not have to resend the whole file. It can resume the file upload from the last successfully sent chunk.

NOTE:
You cannot perform the file upload operation on a virutal folder.

File Upload Intent

Use fileUploadIntent to initialize a file upload intent request. A call to this method returns the URL of the uploaded file and the URL which is used in a call to uploadCommit to upload the pieces of the file.

Request Parameters

path – Path where the file is to be uploaded, such as /VZMOBILE
name – Name of the file to be uploaded
size – Size of the file to be uploaded.
checksum – SHA256SUM of the uploaded file
chunk:
- Set to true for chunked file upload.
- Set to false for un-chunked file upload.

Code Sample

begin
    path = params[:path] || ''
    name = params[:name] || ''
    size = params[:size] || ''
    checksum = params[:checksum] || ''
    chunk = params[:chunk] || 'false'
    entry = client.fileUploadIntent(path,name,size,checksum,chunk)   
  rescue SdkAuthError => e
    session.delete(:access_token)  # An auth error means the access token is probably bad
    logger.info "Sdk auth error: #{e}"
    return html_page "Sdk auth error"
  rescue SdkError => e
    if e.http_response.code == '404'
      return html_page "Path not found: #{h path}"
    else
      logger.info "Sdk API error: #{e}"
      return html_page "Sdk API error  #{e}"
    end
  end

Sdk method used in sample: 
fileUploadIntent

Example Return Response

{
	"uploadurl": "string",
	"commiturl": "string"
}

Return Parameters

uploadurl - URLof the uploaded file
commiturl - URL used in a call to uploadCommit to upload the chunks of the file.

Non-Chunked File Upload

Use upload_data method for non-chunked file uploads. A successful call results in the uploaded file.

Request Parametes

chunk - must be false.
Uploadurl – URL of the uploaded file which has been returned from a call to [fileUploadIntent]().
checksum – Checksum specified in a call to [fileUploadIntent]().
offset– The number that represents we need to send the multiple file for the request. For e.g. if the user breaks the file in 3 parts then offset is 1,2, 3 for three consecutive files.
filepath – Path of the file. This path is required by the SDK to calculate binary data of uploaded file.

Code Sample

 begin
    entry = client.upload_data(uploadUrl, checksum,temp_file.read)

  rescue SdkAuthError => e
    session.delete(:access_token)  # An auth error means the access token is probably bad
    return html_page "Sdk auth error"
  rescue SdkError => e
    logger.info e
    return html_page "Sdk API error #{e}"
  end

Example Return Response

{
	"uploadurl": "string",
	"commiturl": "string"
}

Chunked File Upload

Chunked file upload is performed in two steps:

Call to upload_chunk_data to upload chunks of a file.
Call to uploadCommit to complete chunked file upload.

upload_chunk_data:

Request Parametes

chunk - must be true.
Uploadurl – URL of the uploaded file which has been returned from a call to fileUploadIntent.
checksum – Checksum specified in a call to fileUploadIntent.
offset– The number that represents we need to send the multiple file for the request. For e.g. if the user breaks the file in 3 parts then offset is 1,2, 3 for three consecutive files.
filepath – Path of the file. This path is required by the SDK to calculate binary data of uploaded file.

Code Sample

begin
    offset = 1
    file.each do |filedata|
        temp_file = filedata[:tempfile]
        client.upload_chunk_data(uploadUrl, offset,temp_file.read)	
        offset +=offset
    end
    entry = client.uploadCommit(uploadUrl)	

  rescue SdkAuthError => e
    session.delete(:access_token)  # An auth error means the access token is probably bad
    return html_page "Sdk auth error"
  rescue SdkError => e
    logger.info e
    return html_page "Sdk API error #{e}"
  end

Example Return Response

{
	"uploadurl": "string",
	"commiturl": "string"
}

uploadCommit:

Completes chunked file upload.

Request Parameters

uploadid – URL of the uploaded file which has been returned from a call to fileUploadIntent.

Code Sample

begin

    entry = client.uploadCommit(uploadUrl)	

  rescue SdkAuthError => e
    session.delete(:access_token)  # An auth error means the access token is probably bad
    return html_page "Sdk auth error"
  rescue SdkError => e
    logger.info e
    return html_page "Sdk API error #{e}"
  end

**Required Parameters**

- `src` – Path of the source file to be renamed.
- `target` – Path of the file with the updated name.
- `safe `:
	- If set to *true*, name conflicts are resolved according to the value of the `conflictsolve` parameter. 
	- If set to *false*, the operation overwrites an existing file or folder of the same name. This is the default.
- `conflictsolve` – Defines how name conflicts are resolved if the `safe` parameter is set to *true*:
	-  Set to *copy* to write a file to the destination folder with a non-conflicting name. 
	-  If not set, the operation is rolled back and operation returns `409 Conflict`.

**Note:** `safe` and `conflictsolve` are optional parameters in the request object to rename a file or a folder.
