如何通过REST API上传

Question

I have an angular 5 app and I'm using the primeng upload tool. the api post for uploading requires three parameters: file (file), id (string), fileType (string). I can do the latter two but the file type i just don't understand. the latter two are strings, got it, but how do i address the file part?

this is my json post:

[{ "file" : <<DATA>>, "id": "1234123", "fileType": "doc" }]

What and how to I put in something for the file type?

PrimeNG FileUpload's documentation is quite good so I'd suggest taking a closer look at the documentation at: PrimeNG File Upload

For your specific requirement, I'd suggest taking PrimeNG File Upload and make it as "fancy file picker". Snippets as below:

HTML
<p-fileUpload 
  name="demo[]" 
  auto="true"
  customUpload="true" 
  (uploadHandler)="myUploader($event)" 
  multiple="multiple">
</p-fileUpload>

TS
myUploader(event) {
 consol.log(event.files) //This will return all of the files that are selected. You can omit multiple files by getting rid of `multiple` attribute from the template
//Take this event.files and do whatever you want with it
}

Plunker example, turn on the Console
