问题 @POST @Consumes(MediaType.MULTIPART_FORM_DATA) @Path("/upload") public String upload(@FormDataParam("file") InputStream inputStream) { ... inputStream.close(); // necessary? } For an API endpoint that accepts a file input, do we need to manually close the InputStream or does the framework do it for us? I have checked the Jersey docs but could not find any information about it. Looking for credible source or some way to validate it. 回答1: It is your responsibility to close InputStream. Jersey

问题 I have a file upload handler for multiple file uploads, and have set the MAX_CONTENT_SIZE. The docs mention that Flask throws a 413 exception when the total file size exceeds the limit, so I've also written a 413 error handler with a custom 413 page. However, when testing the file upload, I can see that the 413 error is definitely thrown, but the connection seems to break everytime instead of rendering my error page. FYI, I'm using the Flask dev server currently. Code: app.config['MAX_CONTENT

问题 I'm trying to upload a file with curl, and in the PHP documentation it says: To post a file, prepend a filename with @ and use the full path. The filetype can be explicitly specified by following the filename with the type in the format ';type=mimetype'. This parameter can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data.
