如何在vercel边缘函数中获得客户端IP地址?

Question

我正在向Vercel边缘函数发出GET请求，但似乎无法在API函数内获得IP地址。

所有这些标头值都显示undefined

export const config = {
runtime: "edge",
};

export default async function handler(
req: NextApiRequest,
res: NextApiResponse<APIResponseData>
) {

console.log("realip", req.headers["x-real-ip"]);
console.log("forwardedfor", req.headers["x-forwarded-for"]);
console.log("vercelforwardedfor", req.headers["x-vercel-forwarded-for"]);
console.log("x-vercel-ip-country", req.headers["x-vercel-ip-country"]);


return new Response(
JSON.stringify({
data: {
data: "ok",
},
}),
{
status: 200,
headers: {
"content-type": "application/json"
},
}
);
}

成功了:

边缘功能:

import { ipAddress } from "@vercel/edge";
export const config = {
runtime: "edge",
};
export default function (request: Request) {
const ip = ipAddress(request) || "unknown";
return;
new Response(
`<h1>Your IP is 
${ip}
</h1>`,
{
headers: {
"content-type": "text/html",
},
}
);
}

边缘中间件:

import { ipAddress } from "@vercel/edge";
export const config = {
runtime: "edge",
};
export default function (request: Request) {
const ip = ipAddress(request) || "unknown";
return;
new Response(
`<h1>Your IP is 
${ip}
</h1>`,
{
headers: {
"content-type": "text/html",
},
}
);
}

Answer 2

以下是一些你应该查看的相关链接:

• Vercel文档关于检索客户端IP地址，
• Node.js关于req.socket.localAddress的文档

根据这个，你应该可以用下面的代码得到它:

export const config = {
runtime: "edge",
};
export default async function handler(
req,
res
) {
console.log({ip: req.socket.localAddress});
return {
status: 200,
body: JSON.stringify({
data: "ok",
}),
headers: {
"content-type": "application/json",
},
};
}
