The commonly way to upload data to the server is using FTP client. FTP (File Transfer Protocol) is used to transfer data from one computer (your personal computer) to another computer (webserver). FTP client looks like File Manager and you can copy (upload, download) files here from one computer to another computer.
What you should do is; After setting request method to POST, click to the 'body' tab. Select form-data. At first line, you'll see text boxes named key and value. Write 'image' to the key.
The file is only a part of the data sent in the request, hence the multipart/form-data Content-Type header. If you want to send the file as the only content then you can directly add it as the request body and you set the Content-Type header to the MIME type of the file you are sending.
The content type is per specification multipart/form-data . This is a special content type which can be visualized as multiple sub-requests in one big request. Each of those sub-requests (one form-data element) has their own set of headers. The content type of the actual data is in there.
Follow this rules when creating a multipart form:
- Specify enctype="multipart/form-data" attribute on a form tag.
- Add a name attribute to a single input type="file" tag.
- DO NOT add a name attribute to any other input, select or textarea tags.
To send an attachment to a REST service:
- Open the Attachments panel and click Add Attachment.
- Select the file you want to send. ReadyAPI will ask you if want to cache it in the request.
- Open the Request editor and set the request media type as multipart/form-data or multipart/mixed .
public interface MultipartFile extends InputStreamSource. A representation of an uploaded file received in a multipart request. The file contents are either stored in memory or temporarily on disk. In either case, the user is responsible for copying file contents to a session-level or persistent store as and if desired

Uploading means data is being sent from your computer to the Internet. Even clicking on a link on a web page sends a tiny data upload. Downloading means your computer is receiving data from the Internet.
HTTP PUT. You can also upload a file using an HTTP PUT operation. This is simpler but it doesn't allow sending additional data and web servers usually need special configuration to support PUT operations. In this example, a new input stream is created for a file, and is passed to the XMLHttpRequest's send method.
