Cross domain from browser to express server doesn't work



I know this has been asked more than a hundred times... I did look into most of the information I found, and think I did understand the process, cause I was able to configure my s3 to allow cross domain access..



my express configuration:


this.express = new Express();
this.express.all("*", (req, res, next) => {

res.setHeader('Access-Control-Allow-Origin', "*");
res.setHeader('Access-Control-Allow-Methods', "POST");
res.setHeader('Access-Control-Allow-Headers', "content-type");
next();
}).options((req, res, next) => {
res.end();
});



*I add a router down the modules folder hierarchy..



When I check the network tab this is what I see:



enter image description here



I think that I have answered the CORS challenge, in the pre-flight OPTIONS request, but the second request is not called...



WHY?

Regex - How to capture all iterations of a repeating pattern?

Clash Royale CLAN TAG #URR8PPP Regex - How to capture all iterations of a repeating pattern? Take a look at this example, I want to capture not just the last iteration (which is 5), but also 2, 3 and 4. It says here: A repeated capturing group will only capture the last iteration. Put a capturing group around the repeated group to capture all iterations... but I don't know how to do this. Since I need this in C++, I was looking for a way to get all iterations of capturing group using some regex functions in C++, but I always end up with same groups which the website finds. How about instruction d((,d)*) ? (IMHO, this is meant in the cited text.) Though, this leaves still the task to separate the inner matches... – Scheff 17 mins ago instruction d((,d)*) Thou...
