将字符集从非标准字符集转换为UTF-8

Question

有一个带有<meta charset="EUC-KR">的页面，比如address-search.foo.com，它搜索地址并通过提交如下POST方法的html形式将其发送到指定的url。

let form = <form element>;
form.zipCode.value = "63563";
form.address.value = "제주특별자치도 서귀포시 이어도로 579 (강정동)";
form.action = "https://my-service.foo.com";
form.method = "post";
form.submit();

ExpressJs在my-service.foo.com中运行了一个POST处理程序来处理上面的请求，如下所示。

const next = require("next");
const app = next(nextConfig);
const server = express();
server.use(bodyParser.urlencoded({ extended: false }));
server.use(bodyParser.json());
server.post("/", (req, res) => {
console.log(req.body);
app.render(req, res, "/");
});

以及控制台日志(req.body(；上面打印下面。

[Object: null prototype] {
zipCode: '63563'
address: '����Ư����ġ�� �������� �̾�� 579 (������)'
}

我尝试使用iconv-lite模块转换req.body.address的编码，但它不能像下面这样在PHP上工作。

iconv("CP949", "UTF-8", $_POST['address']); // working very happily

如何正确使用iconv-lite，或者在ExpressJs上有没有绕过它的方法？

使用urlencode模块。

我用bodyParser.raw()而不是bodyParser.urlencoded()解决了这个问题。

const urlencode = require("urlencode");
const iconv = require("iconv-lite");
const qs = require("querystring");
server.use(
bodyParser.raw({ type: "application/x-www-form-urlencoded" }),
(req, res, next) => {
if (req.method === "POST") {
const decoded = iconv.decode(req.body, "utf8");
/**
* Define another conditional statement that filters an encoding specific case.
* Below if statement is just for my case.
*/
if (req.path === "/some/path/to/treat/differently") {
req.body = urlencode.parse(decoded, { charset: "euc-kr" })
}
else {
req.body = qs.parse(decoded);
}
}
next();
}
);
