发布400(错误请求) [英] Post 400 (BAD REQUEST)

问题描述

我正在尝试提交我的表单，但是由于POST出了点问题，它一直失败.我不确定到底是什么导致服务器不处理请求，无论它是否与语法，请求路由等有关.我还注释了与文件上传有关的每一行，并注释了if(validated ) 陈述.因此，控制台中没有错误，但是表单提交仍然失败.感谢您的帮助/指导.

I'm attempting to submit my form, but it continually fails as there's something wrong with the POST. I'm unsure where/what exactly is causing the server to not process the request whether it's related to syntax, request routing, etc. I've also commented out every line related to file uploads, as well as comment out the if (validated) statement. There are no errors in the console as a result of this, but the form submission still fails. I'd appreciate any help/direction thanks.

我提交表单时收到以下错误消息:

I get this error message when I submit the form:

POST http://127.0.0.1:5051/register/ 400(错误请求)

POST http://127.0.0.1:5051/register/ 400 (BAD REQUEST)

推荐答案

通常，bad request表示您正试图使用​​无效键从request对象获取数据.因此，您需要确保您的POST请求正文(由javascript发送)包含您用作request.form.get()方法参数的所有键:first_name，last_name等...

Usually, bad request means that you're trying to fetch data from request object using invalid keys. So you need to make sure that your POST request body (that was sent by javascript) contains all keys which you're using as arguments of request.form.get() method: first_name, last_name, etc...
