什么是express.json()和express.urlencoded()? [英] What are express.json() and express.urlencoded()?

问题描述

我在express.json()和express.urlencoded()上找不到任何文档.他们每个人到底做什么?

I cannot find any documentation on express.json() and express.urlencoded(). What do each of them do exactly?

推荐答案

json和urlencoded中间件都是 bodyParser .这是自述文件的内容:

The json and urlencoded middleware are both part of bodyParser. This is what the README says:

bodyParser([options])

返回同时解析json和urlencoded的中间件. options传递到两个中间件.

bodyParser([options])

Returns middleware that parses both json and urlencoded. The options are passed to both middleware.

返回仅解析json的中间件.选项是:

Returns middleware that only parses json. The options are:

• strict-仅解析对象和数组
• limit< 1mb>-最大请求正文大小
• reviver-传递给JSON.parse()

• strict - only parse objects and arrays
• limit <1mb> - maximum request body size
• reviver - passed to JSON.parse()

返回仅使用 qs 模块解析urlencoded的中间件.选项是:

Returns middleware that only parses urlencoded with the qs module. The options are:

• limit< 1mb>-最大请求正文大小

• limit <1mb> - maximum request body size
