multipartform-data

问题 i want to upload image,video and audio files to a server. I have read this thread on the similar topic but wasn't able to understand completely the flow of the code. It would be great if you can suggest me some sample code or tutorial to start with. I am using the following code to connect without any media to the server [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; NSString *url =[[NSString alloc]initWithFormat:@"%@",[NetworkConstants getURL]]; NSURL *theURL =

问题 I am using Dropwizard 0.7.0 to build an API for file upload. Ran into trouble validating the uploaded file size limit. I want to check the size before writing the file to disk @POST @Consumes(MediaType.MULTIPART_FORM_DATA) @Produces(MediaType.TEXT_PLAIN) public Response uploadFile(@Context final HttpServletRequest request, @FormDataParam("file") FormDataBodyPart fileBodyPart) { /* * Check the request size */ request.getPart("file").getSize(); ......... } it throws an error: java.lang

问题 I tried to search for solution (for 2 days now) bot nothing helps me. Because of many reasons I was forced to write own library in JavaScript to build a multipart/dorm-data body. I checked how other libraries (for node) works and I read the spec. Then I wrote the code (https://github.com/jarrodek/ChromeRestClient/blob/files/app/elements/payload-editor/multipart-form-data.js) which is quite simple because the spec is. However, my test server do not recognise parameters in the request. Any

问题 I have such a method: @RequestMapping(method = RequestMethod.POST) @ResponseStatus(HttpStatus.CREATED) @ResponseBody @PreAuthorize("@securityService.isAllowedAccessByCurrentUser(#resource?.userId)") public Post createPost(@RequestPart(required = false) @Valid final MultipartFile media, @RequestPart(required = true) @Valid PostUploadDto resource, final UriComponentsBuilder uriBuilder, final HttpServletResponse response) { return service.create(resource, media); } In application.properties I

问题 I am writing a code to let the client upload two files on the server. Since I used the director router, I have set a listener like this: request.chunks = []; request.on('data', function (chunk) { request.chunks.push( chunk.toString()); }; and here is the console.log of the chunks when a client uploads a file (based on the browser the boundaries change): -----------------------------7dd2c419180232 Content-Disposition: form-data; name="filename" -----------------------------7dd2c419180232

问题 I'm trying to create a jersey client to hit a server with multipart request. I have the file to upload as a java.io.ByteArrayOutputStream type stream. I searched for the error and came across this question here and this answer here and added register(MultiPartFeature.class) while creating a Client , but to no effect. I probably just need a nudge in the right direction. Thanks! I'm not using Maven or anything. Relevant part from my java file is: FormDataMultiPart multiPart = new

问题 This PNG file can not be uploaded from my app to a 3d-party server. It always reports this error: does multipart has image? I'm sure multipart encoding is correct. Tens of thousands of images are uploaded from my app without this issue. It it the first time. I guess there is something special about this PNG file and I proved it: Dropbox iOS app can not display the image. Tweetbot can not upload it. The error message is "media type unrecognized". So this PNG file is indeed special and quite

问题 I'd like to know {insert_title_here}? I use this method, but with no success: //string data NSString *post = @"message=helloWorld"; NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]; //file data NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:@"ImageFile.png"]; NSData
