Question

我为博客写了一个简单的休息api。我有以下代码（主文件）：

var port = process.env.PORT || 8080; 
var express = require('express'); 
var mongoose = require('mongoose');
var bodyParser = require('body-parser');
var database = require('./config/database');
var app = express(); 
mongoose.connect(database.url);

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true})); 
app.use(express.static('public'));

mongoose.connection.once('open', function () {
    console.log('database connection established');
});

// Routes
app.use('/api/blog', require('./routes/blogroutes.js').router); 

// Start
app.listen(port, function () {
    console.log('listening on port ', port); 
});

文件blogroutes.js如下所示（摘录）：

var express = require('express');
var router = express.Router(); 

var BlogEntry = require('../models/blogEntry');

router.use(function (req, res, next) {
    next();
});

router.route('/entry/:year/:month/:day/:nr')
    //.get(...).delete(...)
    .put(function (req, res) {
        console.log(req.body); 
    });

router.post('/entry', function (req, res) {
    console.log(req.body); 
}); 

module.exports = {router: router};

现在的问题如下：当我调用PowerShell curl -uri http://localhost:8080/api/blog/entry/2016/3/2/3 -method put -body @{title='my first entry';text='Lorem ipsum'}时，控制台输出为{}。当我调用PowerShell curl -uri http://localhost:8080/api/blog/entry -method post -body @{title='my first entry';text='Lorem ipsum'}时，控制台输出符合预期{ text: 'Wonderful', title: 'My second bike trip' }。你知道为什么以及如何进入put体？

Answer 1

因为它看起来不像你正在使用真正的 cURL，而是看起来像是Powershell的Invoke-WebRequest cmdlet，the documentation用于{{1} }具体提到只会Invoke-WebRequest Content-Type application/x-www-form-urlencoded POST}。因此，您需要通过指定其他命令行选项Content-Type来为非POST请求显式设置-ContentType "application/x-www-form-urlencoded"。

NodeJS / Express：PUT和body解析器，body对象为空
