form-data

问题 I have two different JS functions to handle image uploads. One to read the file and to (globally) create the FormData object and the other to send it to a PHP file via AJAX. Even though the file is valid I can't append it to the FormData. And strings neither. And as it turns out I'm only sending empty XHRequests via Ajax, because I don't get any other content from PHP then empty arrays. Since the first JS function initializes the formData variable globally the second function should have no

问题 Consider the following snippet: $('#myBtn').click(function(e) { e.preventDefault(); var formElement = $(this).closest('form')[0]; var request = new XMLHttpRequest(); request.open("POST", "https://posttestserver.com/post.php"); request.send(new FormData(formElement)); }); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form method="POST" action="https://posttestserver.com/post.php"> <input type="text" name="wtf" /> <button type="submit" name="lol"

问题 Is there a way to add additional data to a formdata element that handles a file upload? I know formdata doesn't support .push()? $("frm").submit(function (e) { e.preventDefault(); var data = new FormData($(this)[0]); }); 回答1: If I'm understanding your question correctly, you want to add extra keys and values to the FormData object after taking them from the form. If so, yes you can! It uses the append method: data.append('SomeField', 'SomeValue'); You can do this with a string, or with a Blob

问题 I have a beanstalk reflected in my API gateway with passthrough, where my client sends a direct multipart/form-data request to beanstalk. The image sends correctly and I can open it normally, but when I make the request from the API Gateway, I can't open the image. Looks like the API Gateway encode messes up the image content when performing the passthrough to beanstalk. How I can set the Api Gateway encode or make a pure passthrough? 回答1: I'm Brazilian, so I talked to the Brazilian AWS team.
