How to convert req.body to string?
提问by mobutt
I'm attempting to save req.body to a string in node however whenever I do console.log(req.body.toString) the output is [object Object]. Any idea on what i could be doing wrong?
我试图将 req.body 保存到节点中的字符串,但是每当我执行 console.log(req.body.toString) 时,输出都是 [object Object]。知道我可能做错了什么吗?
var express = require('express');
var app = express();
var fs = require("fs");
var bodyParser = require("body-parser");
app.use(bodyParser.urlencoded({extended:false}));
app.use(bodyParser.json());
app.post('/addUser', function (req, res) {
console.log(req.body.toString());
res.end("thanks\n");
})
Output is:
输出是:
[object Object]
[object Object]
When using JSON.stringify the output is:
使用 JSON.stringify 时,输出为:
" [object Object] "

Use JSON.stringify()
to convert any JSON or js Object(non-circular) to string.
So in your case the following will work.
使用JSON.stringify()
任何JSON或JS对象(非圆)转换为字符串。因此,在您的情况下,以下内容将起作用。
console.log(JSON.stringify(req.body))

Try this
尝试这个
JSON.stringify(req.body);
Object.prototype.toString will allways return a string with object + type, unless you override it.
Object.prototype.toString 将始终返回带有对象 + 类型的字符串,除非您覆盖它。

it is a circular object so u need to stringify it as follow
它是一个圆形对象,因此您需要将其字符串化如下
console.log(JSON.stringify(req.body)
