Parse numbers from query strings with bodyParser.urlencoded() in express.js

由 走远了吗. 提交于 2020-02-25 09:39:52
问题 In the front end, I use jQuery to send a GET request like this: $.get('/api', {foo:123, bar:'123'), callback); according to jQuery doc, the 2nd parameter is a plain object that will be converted into query string of the GET request. In my node express back end, I use body-parser like this: const bodyParser = require("body-parser"); app.use(bodyParser.urlencoded({ extended: true })); app.get('/api', (req, res) => { console.log(req.query) // req.query should be the {foo:123, bar:'123'} I sent }

I did some searching and found that I can change the body size limit using the body-parser package, along with the bodyParserConfig option set in middleware. I've tried implementing this, as well as implementing it in the express app itself, however neither seem to be working. bodyParserConfig

Express body-parser handling checkbox arrays on forms

问题 I have an HTML form with an array of checkboxes (using [] naming). I need to be able to process this with express . I'm using body-parser . The problem is that unchecked checkboxes don't submit a value, and at the same time, body-parser seems to remove "holes" in arrays by simply packing the values into an array in order of indices, but ignoring the indices themselves. (Update: Actually it looks like qs is the culprit). Consider this full example, which displays a form and responds with a
