解码ReadableStream对象nextjs 13 api路由

Question

我正在向服务器端代码发送一个不能正确读取的值。我使用NextJS实验应用程序目录

//src/app/api/auth/route.js
export async function POST(req, res) {
console.log(req.body);
const { address } = req.body;
const isAuthenticated = await checkBalance(address, threshold);
if (isAuthenticated) {
return new Response("Authorized", { status: 200 });
} else if (isAuthenticated == false) {
return new Response("Unauthorized", { status: 401 });
} else if (isAuthenticated == undefined) {
return new Response("Error", { status: 500 });
}
}

控制台日志为:ReadableStream { locked: false, state: 'readable', supportsBYOB: false }

const address isundefined.

这是api调用:

const response = await fetch("/api/auth", {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({ address: walletAddress }),
});
const data = await response.json();

我在另一个类似的问题的答案中读到nextjs12+应该自动解析请求-我做错了什么?我假设nextjs有一个解码ReadableStream的协议，但我在文档或例子中找不到任何东西，也许是因为有一个框架不可知的方法来解码我未知的对象?

提前谢谢你。

Answer 1

我遇到过一个类似的问题，你可以试试这个:

const body = await req.json()
const {address} = body
// the rest of your code 

Answer 2

你需要等待来自nextjs的请求，以便获得body对象。就像下面的代码:

import { NextResponse } from "next/server";
export async function POST(req) {

const body = await req.json();
console.log(body);

return NextResponse.json(body);
}

Answer 3

我想你应该这样做:

...
const { address } = req.body
const isAuthenticated = await checkBalance(address, threshold);
...

Answer 4

一个discord用户推荐const address = await req.json();而不是const {address} = req.body，并且它有效。
