My form doesn't send the data. I need to upload files, but my code has no responses if I put enctype="multipart/form-data", it doesn't show an error or anything, it just doesn't work. My form: @csrf Nome do jogoPlatformSelecione a PlataformaConsolePcMobilegame image Descrição do jogoSave I tried several ways, but it didn't work. Something is wrong? No, I didn't misunderstand. But the simple fact is this: adding that enctype attribute does not, by itself, prevent a HTML form from working at all. It's a commonly-used attribute and works perfectly well. Something else must be happening in combination with that, which is causing you some sort of problem. And I say "some sort of problem" because also you still not explain what "stops working" actually means, specifically. That description is vague and could cover 100 different particular problems.

This attribute is commonly used in HTML forms to specify the encoding type used when submitting the form data to the server. In this blog post, we’ll explore the enctype attribute in depth, specifically the multipart/form-data encoding type. We’ll cover what it is, how it works, and when you should use it. What is multipart/form-data? multipart/form-data is an encoding type used when submitting binary data or files through an HTML form. This encoding type is used to ensure that the data is transmitted in a way that is compatible with all web servers and browsers. When you submit a form with enctype="multipart/form-data", the form data is encoded using a combination of binary and ASCII ch...

For the most part, you will use forms to capture data from the user as simple string, numeric, datetime or boolean values. Forms can also be used to upload files. Successful file uploading has three basic requirements: • The form must use the post method • The form must have an enctype attribute set to multipart/form-data • The uploaded file must map to an IFormFile data type Upload and save to folder The following code features a very simple page called UploadFile.cshtml with a form for uploading a file: @page @model UploadFileModel @ An IFormFile is added as a public property to the to the page model. It is decorated with the BindProperty attribute, to ensure that it participates in name attribute on the file input in the form - "Upload" which ensures that model binding will copy the contents of the upload to the public property. IHostingEnvironment is injected into the constructor of the page model class via ContentRootPath property, which is used to construct a file path location for the uploaded file to be saved to in the asynchronous OnPost handler method.

模拟multipart/form-data请求 原以为requests请求十分强大， 但遇到了模拟multipart/form-data类型的post请求， 才发现requests库还是有一丢丢的不足。 不过也可能是我理解的不足， 还希望读者老爷不吝指教！ 在此感谢！ 1. 什么是multipart/form-data请求 enctype属性: enctype：规定了form表单在发送到服务器时候编码方式，它有如下的三个值。 ①application/x-www-form-urlencoded：默认的编码方式。但是在用文本的传输和MP3等大型文件的时候，使用这种编码就显得 效率低下。 ②multipart/form-data：指定传输数据为二进制类型，比如图片、mp3、文件。 ③text/plain：纯文体的传输。空格转换为 “+” 加号，但不对特殊字符编码。 2. multipart/form-data请求请求体的格式(以某网站模拟登录为例) # coding: utf-8 from collections import OrderedDict import requests # 构建有序字典 params = OrderedDict([( " username ", (None, ' 130533193203240022 ' )), ( " password ", (None, ' qwerqwer ' )), ( ' captchaId ', (None, ' img_captcha_7d96b3cd-f873-4c36-8986-584952e38f20 ' )), ( ' captchaWord ', (None, ' rdh5 ' )), ( ' _csrf ', (None, ' 200ea95d-90e9-4789-9e0b-435a6dd8b57b ' ))]) res = requests.get( ' http://www.baidu.com ', files= params) print res.request.body 打印的结果： -- 6c7a1966e0294e1cb89b06b95cf3da84 Content-Disposition: form-data; name= " username " 130533193203240022 -- 6c7a1966e0294e1cb89b06b95cf3da84 Content-Disposition: form-data; name= " password " qwerqwer -- 6c7a1966e0294e1cb89b06b95cf3da84 Content-Disposition: form-data; name= " captchaId " img_captcha_7d96b3cd-f873-4c36-8986- 584952e38f20 -- 6c7a1966e0294e1cb89b06b95cf3da84 Content-Disposition: form-data; name= " captchaWord " rdh5 -- 6c7a1966e0294e1cb89b06b95cf3da84 Content-Disposition: form-data; name= " _csrf " 200ea95d-90e9-4789-9e0b- 435a6dd8b57b --6c7a1966e0294e1cb89b06b95cf3da84-- 需要注意的是， ...
