將字符集從非標准字符集轉換為 UTF-8

Question

有一個帶有<meta charset="EUC-KR">的頁面，比如 address-search.foo.com 搜索地址並將其發送到指定的 url 通過提交 ZFC35FDC70D5FC69D269883A82ZC 的方法如下所示。

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 運行的 my-service.foo.com 中有一個 POST 處理程序來接受上述請求，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, "/");
});

和 console.log(req.body); 上面打印下面。

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

我嘗試使用iconv-lite模塊轉換req.body.address的編碼，但它不像在 PHP 上那樣工作，如下所示。

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

如何正確使用iconv-lite或者無論如何可以在 ExpressJs 上解決這個問題？

Answer 1

使用urlencode模塊。

我通過使用bodyParser.raw()而不是bodyParser.urlencoded()解決了這個問題。

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();
  }
);
