multipartform-data

I have been trying to research a way to be able to send nested JSON requests via Ajax back to the server. From my understanding formdata that we mostly use for sending images or files to the server wont work in this scenario, since it seems like FormData does not handle nested objects. This is the kind of payload I need to send. Any suggestions? payload = { 'login':{ 'key':'some_key' }, 'user':{ 'doc':{ 'dp':<here will be the image file>, 'date':"some date", 'extra':"extra info" }, 'fingerprint':'some_fingerprint' } } I've never been able to send image data over Json, but I have been able to

I want to arrange file in front of data. If I try the traditional way, the data appears in front of file. To be more specifically, I want myfile to appear before form_value . form_value={'exp':'python', 'ptext':'text', 'board':'Pictures'} myfile = {'up': ('aa.png', open('aa.png', 'rb'), 'image/png')} r = requests.post(url, files=myfile, data=form_value, cookies=cookie) result Content-Type: multipart/form-data; boundary=170e4a5db6d74d5fbb384dfd8f2d33ce --170e4a5db6d74d5fbb384dfd8f2d33ce Content-Disposition: form-data; name="ptext" text --170e4a5db6d74d5fbb384dfd8f2d33ce Content-Disposition:

I'm looking for a way to send model and image in one request. I tried to send my model from body, but I don't know how to send the file. Is there another way than sending image and model in a different files? Here's the POST method from my API: [HttpPost] [Route("UploadNewEvent")] public async Task<IActionResult> CreateNewEventAsync([FromBody] EventModel model) { var file = this.Request.Form.Files.LastOrDefault(); if (file != null) { var uploads = Path.Combine(_environment.WebRootPath, "uploads"); using (var fileStream = new FileStream(Path.Combine(uploads, "test.jpg"), FileMode.Create)) {

Is there an equivalent to this statement in jQuery? var value = document.getElementById(id).files[0]; Using the standard jQuery selectors with .files[0] appended doesn't appear to work, and I can't find an equivalent jQuery command to .files. Any suggestions? I'm using this to retrieve the file from an input type='file' form element. $('#id').get(0).files[0] get(0) return DOM element 来源： https://stackoverflow.com/questions/11443886/javascript-files0-attribute-in-jquery

I have a file in memory (in a buffer), it doesn't exist on the file system (so I can't just stream that). I'm trying to send it to SignServer using HTTP. Here's how I try to do it: var formdata = require('form-data'); var form = new formdata(); form.append('workerName', 'PDFSigner'); form.append('data', file_buffer); // or // escape(file_buffer.toString('binary')) // or // file_buffer.toString('binary') (without escaping) var request = form.submit('http://localhost:8080/signserver/process', function(err, res) {}); When I try appending file_buffer SignServer says that data is empty: Status 400
