multipartform-data

问题 I'm trying to consume a web service that accepts a CommonsMultipartFile in the request. So, I created an HTTP client using Spring's RestTemplate. Below is the method that takes in URI and a MultipartFile as parameters. I'm trying to pass this file to the web service in the form of ByteArrayResource. public String upload(String uri, MultipartFile file) throws IOException { logger.info("URI: " + uri); ByteArrayResource fileAsResource = new ByteArrayResource(file.getBytes()) { @Override public

问题 I am posting to an API that seems to insist on receiving XML data as multipart/form-data with the name (file name?) xml. It works in postman but I can't get it to work using Python's requests. This is my Python code (based on https://stackoverflow.com/a/24443309/1011724): requests.post(callpro_url, files={'xml':('data.xml',result)}, verify=False).text where result is a string containing XML. If I try this code I get the response: xml post field is empty which is the response this API give if

问题 I am uploading image files, and I need them to work with accented characters - so I have made everything use UTF-8 . I use this javascript function to upload them: $('#files').change(function(e) { var formData = new FormData(); for (var i=0; i<this.files.length;i++){ formData.append(this.files[i].name, this.files[i]); } var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(e) { if ( 4 == this.readyState ) { showMessage("Uploaded."); } }; xhr.open('post', 'accoms/upload.jsp', true)

问题 I've been working on this all day now, and I just can't get it working. I have basically got a simple ajax request using the jQuery library and I want to send the data which I post through a mutlipart/form-data file input, however, I have tried everything I can think of. My File upload script is in place awaiting the file name as a parameter (tried without also), but it just doesn't want to get the data from the file input box itself. Could someone please enlighten me on how to do this

问题 I am working on a Spring web application and need to implement a simple FileUpload for one of my pages. The page for the JSP contains the following snippet of code which included an upload field for uploading the file. <form:form commandName="editMemberInfoModelObj" method="post" enctype="multipart/form-data"> <h1>Edit Member Information</h1> <table> //Other Form Input Fields ... <tr> <td>File</td> <td><input type="file" name="file"/></td> </tr> <tr> <td><input type="submit" value="Update

问题 I have a working Web service that allows me to upload a file. I'd like to put Mule 3 in front of it but I have not been successful in getting it to pass along payloads whose MIME type is "multipart/form-data". Attempts to do so produce a 400 error: "The request sent by the client was syntactically incorrect (Bad Request)." The following flow (which doesn't accomplish my purpose but serves as a test) works fine, passing along whatever text I POSTed. <flow name="Flow1" doc:name="Flow1"> <http

问题 I'm trying to implement a rest api consuming excel file. I'm using spring-boot and code is available here. Code works fine when using FileSystemResource for payload. But i'm not able to make the code work with ByteArrayResource in replacement of FileSystemResource : RestApi.java: @RestController public class RestApi { private static final Logger LOGGER = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass()); @PostMapping("/api/upload") public ResponseEntity<?> uploadFile(@RequestParam

问题 I have a react native app that allows users to upload images to the server along with additional data. I'm using NodeJS and ExpressJS as my backend framework. The route for posting images: router.post("/", checkAuth, upload.single("gallery_item_image"), function (req, res, next) { Branch .findById({ _id: req.body.branch_id }) .exec() .then((doc) => { if(!doc) { return res.status(404).json({ message: "Invalid Branch ID", }) } galleryItem = new GalleryItem({ _id: mongoose.Types.ObjectId(),

问题 I'm was making a drag and drop upload script by reading a bunch of tutorials, but they only cover the javascript part, and i'm having issues on the php part. I'm uploading a image as this: $('#drop-zone').bind('drop', drop); function drop(e) { e.stopPropagation(); e.preventDefault(); e.dataTransfer = e.originalEvent.dataTransfer; traverseFiles(e.dataTransfer.files); } traverseFiles makes a foreach loop for every file and calls upload funcion, there i do this: xhr = new XMLHttpRequest(); /

问题 I am trying to upload data from an app to a spring backend service. Things to upload are a DataModel containing data of the object to create and several images linked to the data. Therefore I am using this method signature: @RequestMapping(method = RequestMethod.POST) @ResponseBody public Survey createSurvey(@RequestBody SurveyPostHelper helper, @RequestParam(value="file", required = true) MultipartFile[] images) I tried to play with the annotations, but either I get a blank images array or
