I am crawling a web page and there comes a time when I need to upload a file, this Crawler is to test a system. What I need to do is with the pure javascript inputar a document on the following page:
<label for="avatar">Choose a profile picture:</label>
<input type="file"
id="avatar" name="avatar"
accept="image/png, image/jpeg">
Does anyone know how to do that ?
Thanks in advance.

Guys I managed to solve.
Basically what I had to do was to perform an ajax request on the file I wanted to insert forcing the request to return a bluble object (which is the file in binary format).
After that with this file in hand I checked the upload function that was called in the upload, called this function by passing the parameters and my binary file. With that he went to the server.
I appreciate the support.
It would be interesting to post the code in the answer.

You want a script that accesses this URL and sends a predetermined file to the server that hosts this page, that’s what you want?

There is no way to input files from the client’s machine, if this were possible it would be one of the biggest security loopholes that a browser would have.

Missing the main, the code you already have! Using what? Puppeteer? Phantomjs? Selenium? Anyway, you need the code you already have.

I use a class that was developed with dryscrap , I already have the code that navigates the page and fills normal fields , this class I use has a function that allows you to run pure javascript on the screen, this javascript that I use to fill the fields, however simulating a file is complicated, with Puppeteer I can go up because it already has a function of its own.

In Puppeteer it would be like this
var findelement = await page.$("#file"); 
 await findelement.uploadFile("teste.pdf"); //Caminho do arquivo relativo ao script.– Felipe Tolentino
