如果我禁用 NODE_TLS_REJECT_UNAUTHORIZED，我的请求仍然被拒绝

Question

我正在禁止节点拒绝自签名证书并发出请求。

const { USER, PW } = process.env;

const b64 = new Buffer(`${VP_API_USER}:${VP_API_PW}`).toString("base64");

const Authorization = `Basic ${b64}`;

const doFind = async url => {
  process.env.NODE_TLS_REJECT_UNAUTHORIZED = 0;
  const results = await fetch(url, { headers: { Authorization } })
    .then(r => (r.ok ? r.json() : Promise.reject(r)))
    .catch(err => {
      return Promise.reject(err);
    });
  process.env.NODE_TLS_REJECT_UNAUTHORIZED = 1;

  return results;
};

我仍然被拒绝。

我究竟做错了什么？

Answer 1

process.env.NODE_TLS_REJECT_UNAUTHORIZED = 1;

行应该进入回调内部（您的 then 或 catch 在返回之前。因为承诺在回调中得到解决，但是您的行

process.env.NODE_TLS_REJECT_UNAUTHORIZED = 1;

写在它的外面，即使它出现在语句之后，它也会立即运行，而不需要等待回调。因此，您的 tls 实际上从未被禁用。

我希望这有帮助：）
