每次我尝试在邮递员中向 http://localhost:3000/api/orders/new

我发现在指定路由路径之前需要使用此代码。

Answer 2

这是解决方案...是的！

不需要安装body-parser。

尝试一下：

app.use(express.json())

并在诸如以下路线之前指定它：

（顺序在这里确实很重要！）

app.use(express.json());
app.use('/api', Anyroute)

Answer 3

您可能缺少bodyParser：

const bodyParser = require('body-parser')

app.use(bodyParser.json()) // for parsing application/json

Answer 4

确保将数据作为原始和 JSON 传递，如下图所示。

Answer 5

我在server.ts中拥有

app.use('/admin', adminRoutes);
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }))

给出了错误信息。更改为

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }))
app.use('/admin', adminRoutes);

使其起作用。就像OP在评论中所说的那样，顺序必须首先是正文解析器，然后是路由路径。
