API 请求卡在 POSTMAN 中?
API request getting stuck in POSTMAN?
所以,我正在制作一个使用 Mongo 数据库和 Express JS 作为后端的电子商店应用程序。我已经创建了 productSchema、userSchema 和 categorySchema,并为适当的 GET 请求编写了代码。
我制作了一个 jwt.js 文件,它根据令牌处理是否应允许 GET 请求。
jwt.js 的代码如下
const { expressjwt } = require("express-jwt");
function authJwt() {
const secret = process.env.secret;
const api = process.env.API_URL;
return expressjwt({
secret,
algorithms: ["HS256"],
isRevoked: isRevoked,
}).unless({
path: [
{ url: /\/api\/v1\/products(.*)/, methods: ["GET", "OPTIONS"] },
{ url: /\/api\/v1\/categories(.*)/, methods: ["GET", "OPTIONS"] },
`${api}/users/login`,
`${api}/users/register`,
],
});
}
async function isRevoked(req, payload, done) {
if (!payload.isAdmin) {
done(null, true);
}
done();
}
module.exports = authJwt;
products.js 处理产品数据库的 GET、POST、PUT 和 DELETE 请求的代码如下。
const { Product } = require("../models/product");
const express = require("express");
const { Category } = require("../models/category");
const router = express.Router();
const mongoose = require("mongoose");
router.get(`/`, async (req, res) => {
// localhost:3000/api/v1/products?categories=2342342,234234
let filter = {};
if (req.query.categories) {
filter = { category: req.query.categories.split(",") };
}
const productList = await Product.find(filter).populate("category");
if (!productList) {
res.status(500).json({ success: false });
}
res.send(productList);
});
router.get(`/:id`, async (req, res) => {
const product = await Product.findById(req.params.id).populate("category");
if (!product) {
res.status(500).json({ success: false });
}
res.send(product);
});
router.post(`/`, async (req, res) => {
const category = await Category.findById(req.body.category);
if (!category) return res.status(400).send("Invalid Category");
let product = new Product({
name: req.body.name,
description: req.body.description,
richDescription: req.body.richDescription,
image: req.body.image,
brand: req.body.brand,
price: req.body.price,
category: req.body.category,
countInStock: req.body.countInStock,
rating: req.body.rating,
numReviews: req.body.numReviews,
isFeatured: req.body.isFeatured,
});
product = await product.save();
if (!product) return res.status(500).send("The product cannot be created");
res.send(product);
});
router.put("/:id", async (req, res) => {
if (!mongoose.isValidObjectId(req.params.id)) {
return res.status(400).send("Invalid Product Id");
}
const category = await Category.findById(req.body.category);
if (!category) return res.status(400).send("Invalid Category");
const product = await Product.findByIdAndUpdate(
req.params.id,
{
name: req.body.name,
description: req.body.description,
richDescription: req.body.richDescription,
image: req.body.image,
brand: req.body.brand,
price: req.body.price,
category: req.body.category,
countInStock: req.body.countInStock,
rating: req.body.rating,
numReviews: req.body.numReviews,
isFeatured: req.body.isFeatured,
},
{ new: true }
);
if (!product) return res.status(500).send("the product cannot be updated!");
res.send(product);
});
router.delete("/:id", (req, res) => {
Product.findByIdAndRemove(req.params.id)
.then((product) => {
if (product) {
return res
.status(200)
.json({ success: true, message: "the product is deleted!" });
} else {
return res
.status(404)
.json({ success: false, message: "product not found!" });
}
})
.catch((err) => {
return res.status(500).json({ success: false, error: err });
});
});
router.get(`/get/count`, async (req, res) => {
const productCount = await Product.countDocuments((count) => count);
if (!productCount) {
res.status(500).json({ success: false });
}
res.send({
productCount: productCount,
});
});
router.get(`/get/featured/:count`, async (req, res) => {
const count = req.params.count ? req.params.count : 0;
const products = await Product.find({ isFeatured: true }).limit(+count);
if (!products) {
res.status(500).json({ success: false });
}
res.send(products);
});
module.exports = router;
现在,users.js 和 categories.js 的代码相似,因此我不分享它。
我在使用 POSTMAN API 对产品进行 GET 请求时遇到问题。即使我在 POSTMAN API 中使用 BEARER TOKEN 字段传递了正确的令牌,它仍然无法发送请求。当我删除 isRevoked 部分时,一切正常,但我又无法控制基于 isAdmin 部分的获取请求。所以,问题出在 isRevoked 部分。但是,究竟是什么问题。逻辑上我觉得没问题。
问题可能由很多事情引起,如果不深入查看您的代码就无法确定,但是,这里有一些建议:
- isRevoked 应该是异步的吗?
- 您的负载是否包含 isAdmin?
如果是这样,在 if 语句内应该是
done(null, false)
在 if 语句之后你应该得到一个 userid 或任何类型的唯一字段,如 userEmail,......,然后使用你的 userModel 来查询用户文档,以便你最后 done()
是 done(null, user)
