Question

我禁止Node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。

我在做什么错了？

Answer 1

process.env.NODE_TLS_REJECT_UNAUTHORIZED = 1;

该行应放在回调内部（您或然后在返回之前捕获。因为一个承诺在回调中得到解决，但您的行

process.env.NODE_TLS_REJECT_UNAUTHORIZED = 1;

是写在它外面的，即使它出现在语句之后，它也可以立即运行而无需等待回调。因此，永远不会禁用您的tls。

我希望这会有所帮助：）

Answer 2

上一个答案似乎不正确-等待推迟下一行的执行，直到承诺将被解决。根据{{3}}，NODE_TLS_REJECT_UNAUTHORIZED值应为字符串“ 0”以禁用TLS验证。

Answer 3

如果我事后必须重置环境变量，我会这样做。

使用 .finally()，无论获取的结果如何，语句都会执行。

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);
    })
    .finally(() => {
      process.env.NODE_TLS_REJECT_UNAUTHORIZED = 1;
    });
  return results;
};

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