How to upload an image to the VK server?

Question

JavaScript

I wrote an image parser, which for now just downloads the necessary pictures into a folder. Further, according to the plan, any image from the folder is uploaded to the VK server using a link received in advance via the API. How to implement on node?

Answer 1

You can create an array "files" and add paths to files (no more than five) to it, as well as parse the resulting link with the "parse" function of the "url" module, writing the result to the "URL" variable. Further code could be like this:

boundary = "H#pB$Ky6Vs+Q8ioY_buA"
data = ""

for (i = 0; i < files.length; i++) {data += "--" + boundary + "\r\nContent-Disposition:form-data;name=file" + (i + 1) + ";filename=.png" + "\r\n\n" + fs.readFileSync(files[i]).toString("binary") + "\r\n"}

data += "--" + boundary + "--"

request = http.request(
  {
    method: "POST",
    path: URL.path,
    host: URL.host,
    headers: {"Content-Type": "multipart/form-data;boundary=" + boundary}
  },

  function (response) {
    var data = ""

    response.on("data", function (chunk) {data += chunk})
    response.on("end", function () {/* здесь можно распарсить ответ сервера и получить ссылки на изображения без использования метода «photos.save» */})
  }
)

request.write(data, "binary")
request.end()

You can do it like this)
1) Write an application authorization script. So that he can get the rights https://vk.com/dev/permissions . Or find a ready-made module, by the way, there are a lot of them in npm)
2) Choose a method for uploading an image, most likely this is https://vk.com/dev/photos.getUploadServer com/dev/methods
