英文:
node not showings single details in postman with params
问题
在我的React项目中，我需要使用参数从详情页获取单个详细信息，但响应未发送到Postman。在发送请求后，响应未在Postman中返回。
index.js
import express from "express";
import cors from "cors";
import mongoose from "mongoose";
import { userRouter } from "./routes/users.js";
import { recipesRouter } from "./routes/recipes.js";
const app = express();
app.use(express.json());
app.use(cors());
app.use("/auth", userRouter);
app.use("/recipes", recipesRouter);
mongoose.connect(
"xxxxxxxxxxxxxxxxxxxxxx"
);
app.listen(3001, () => console.log("服务器已启动"));
router
import express from "express";
import mongoose from "mongoose";
import { RecipeModel } from "../models/Recipes.js";
import { UserModel } from "../models/User.js";
const router = express.Router();
router.get("/createrecipe/:id", async (req, res) => {
let result = await RecipeModel.findOne({ id: req.params.id });
if (result) {
res.send(result);
} else {
res.send('没有食谱');
}
})
Postman
使用以下请求URL来获取单个详细信息：
GET请求：http://localhost:3001/createrecipe/1
在详情页和Postman中查看单个详细信息。
英文:
In my react project i need fetch single details to details page with params but the response not sending to postman.after sending request the response not coming in postman
index.js
import express from "express";
import cors from "cors";
import mongoose from "mongoose";
import { userRouter } from "./routes/users.js"
import { recipesRouter } from "./routes/recipes.js"
const app = express();
app.use(express.json());
app.use(cors());
app.use("/auth", userRouter);
app.use("/recipes", recipesRouter);
mongoose.connect(
"xxxxxxxxxxxxxxxxxxxxxx"
);
app.listen(3001, () => console.log("SERVER STARTED"));
router
import express from "express";
import mongoose from "mongoose";
import { RecipeModel } from "../models/Recipes.js"
import { UserModel } from "../models/User.js";
const router = express.Router();
router.get("/createrecipe/:id", async (req, res) =>{
let result =await RecipeModel.findOne({id:req.params.id});
if(result){
res.send(result)
}else{
res.send('no recipe')
}})
postman
get--http://localhost:3001/createrecipe/1
<body>
<pre>Cannot GET /createrecipe/1</pre>
</body>
need to see the single details in details page and postman.

在app.use("/recipes", recipesRouter)中，您正在使用"/recipes"前缀来定义recipesRouter中的所有路由，但您却调用了http://localhost:3001/createrecipe/1而不是http://localhost:3001/recipes/createrecipe/1。
英文:
In app.use("/recipes", recipesRouter) You are prefixing all routes in recipesRouter with /recipes but you are calling http://localhost:3001/createrecipe/1 instead of http://localhost:3001/recipes/createrecipe/1
