javascript - Typescript - 替换 url 映射中的字符串

Question

我有一张这样的 map :

const urlPaths = {
        "Signature": "signature/(signatureId)",
        "Rule": "signature/(signatureId)/rule/(ruleId)",
    };

然后我的 API 中会出现一些数据，例如:

aId: {
    signatureId: "999"
}

或

aId: {
    signatureId: "123",
    ruleId: "456"
}

我希望能够使用该映射，返回签名或规则的 url，例如:

“签名/999”或“签名/123/rule/456”

我遇到过正则表达式替换，但想知道，在这种情况下我真的可以使用它吗？

function createUrl(url, regex, aId){
   url.replace(regex,(id) => aId[id])
}

不确定是否可能/如何处理或者我需要其他东西吗？

任何想法表示赞赏。

谢谢。

不确定 RegExp 是否绝对必要，因为您要替换的模式与您的属性名称相匹配。你可以这样做:

const urlPaths = {
  "Signature": "signature/(signatureId)",
  "Rule": "signature/(signatureId)/rule/(ruleId)",
};

const aId1 = {
    signatureId: "999"
};

const aId2 = {
  signatureId: "123",
  ruleId: "456"
};

const createUrl = (url, aId) => {
  let newUrl = url;
  Object.entries(aId).forEach(([key, value]) => {
    newUrl = newUrl.replace(`(${key})`, value);
  });
  return newUrl;
}

console.log(createUrl(urlPaths.Signature, aId1));
console.log(createUrl(urlPaths.Rule, aId2));

如果您确实想使用 RegExp，这里还有一个示例说明它的工作原理

const urlPaths = {
  "Signature": "signature/(signatureId)",
  "Rule": "signature/(signatureId)/rule/(ruleId)",
};

const aId1 = {
    signatureId: "999"
};

const aId2 = {
  signatureId: "123",
  ruleId: "456"
};

const createUrlRegExp = (url, regexs, aId) => {
  let newUrl = url;
  const replacer = match => aId[match.slice(1, -1)]; // get rid of parentheses around match
  regexs.forEach(regex => {
    newUrl = newUrl.replace(regex, replacer)
  });
  return newUrl;
};

console.log(createUrlRegExp(urlPaths.Signature, [/\(signatureId\)/], aId1));
console.log(createUrlRegExp(urlPaths.Rule, [/\(signatureId\)/, /\(ruleId\)/], aId2));
