我可以将 https 网址与：
if(url.match('^http://')){
but how do I form the https url using regular expressions and javascript?
但是如何使用正则表达式和 javascript 形成 https url？
url = "https://" + ?;

Replace directly with a regex :
直接用正则表达式替换：
url = url.replace(/^http:\/\//i, 'https://');

Cannot it be done by simply replacing the httpstring?
不能通过简单地替换http字符串来完成吗？
if(url.match('^http://')){
url = url.replace("http://","https://")
}

Depending on your case, you might prefer to slice:
根据您的情况，您可能更喜欢切片：
processed_url = "http" + initial_url.slice(5);
Example of http to https:
http 到 https 的示例：
var initial_url;
var processed_url;
initial_url = "http://stackoverflow.com/questions/5491196/rewriting-http-url-to-https-using-regular-expression-and-javascript";
processed_url = "https" + initial_url.slice(6);
console.log(processed_url)
Example of https to http:
https 到 http 的示例：
var initial_url;
var processed_url;
initial_url = "https://stackoverflow.com/questions/5491196/rewriting-http-url-to-https-using-regular-expression-and-javascript";
processed_url = "http" + initial_url.slice(5);
console.log(processed_url)
