multipartform-data

问题 This is my serializer: class ParentSerializer(serializers.ModelSerializer): children = ChildSerializer(many=True) # reverse FK relation ParentSerializer also has an image field, so the request has to be multipart/form-data to support both image and data in a single request. The following code/test works fine: test_data = QueryDict('', mutable=True) dictionary = { 'name': ['test'], 'children[0]': [{'key1': 'val1', 'key2': 'val2'}] } test_data.update(MultiValueDict(dictionary)) test_serializer

问题 I have a wicket form that has a file upload box on it. Sometimes this file upload box is hidden because the user isn't required to attach documentation. I have called setMultiPart(true) on the form object , but I still (but only rarely) get this error: java.lang.IllegalStateException: ServletRequest does not contain multipart content. One possible solution is to explicitly call Form.setMultipart(true), Wicket tries its best to auto-detect multipart forms but there are certain situation where

问题 I have the content I want to POST available in a string variable. I want to use: import { HttpClient } from '@angular/common/http' ... in order to accomplish the same effect as: curl -F "image=@blob.bin" someurl.com ... where the contents of my string variable would be what might be in a local file called `blob.bin. I'm not sure how to do it, but this doesn't work: this.http.post('http://someurl.com', fileContents) How do you get this effect using Angular 7 and the HttpClient service? I don't

问题 I have a form where I simultaneously send several (let's say 10) files to the backend, along with some other regular input fields. When I find a validation problem in the backend I display the form again and fill the regular inputs (dropdowns, text inputs, etc.), but I cannot fill the file fields, forcing the user to select the files from the file directory again. The solution I think of is sending the base64 encoded representation of the files, and put them back in the form in case there is

问题 I've been trying to post a multipart/form-data object with text and an image file to one of my cloud functions, according to the documents here: https://cloud.google.com/functions/docs/writing/http#multipart_data_and_file_uploads I've kept my cloud function almost entirely the same as the example, except I've wrapped it in a CORS response. It seems though, that no matter what, busboy's 'field' and 'file' events never fire, and when I print the request body's toString method, I get some of the

问题 I am stuck trying to get Swashbuckle 5 to generate complete help pages for an ApiController with a Post request using multipart/form-data parameters. The help page for the action comes up in the browser, but there is not included information on the parameters passed in the form. I have created an operation filter and enabled it in SwaggerConfig, the web page that includes the URI parameters, return type and other info derived from XML comments shows in the browser help pages; however, nothing
