I'm working on an iPhone app that makes a multipart HTTP request with multiple image files.
It looks like what's happening, on the server side, is that one of the images is getting parsed properly, but the other two files are not.
Can anybody post a sample HTTP multipart request that contains multiple image files?

An HTTP multipart request is an HTTP request that HTTP clients construct to send files and data over to an HTTP Server. It is commonly used by browsers and HTTP clients to upload files to the server.
Uploading Multiple Files const uploadFile = (files) => { console. log("Uploading file..."); const API_ENDPOINT = "https://file.io"; const request = new XMLHttpRequest(); const formData = new FormData(); request. open("POST", API_ENDPOINT, true); request. onreadystatechange = () => { if (request.
Multipart requests combine one or more sets of data into a single body, separated by boundaries. You typically use these requests for file uploads and for transferring data of several types in a single request (for example, a file along with a JSON object).
Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").
