Worker fetch will not use the system proxy

Describe the solution

When I run

wrangler dev

wrangler dev

wrangler dev

wrangler dev for local development, I have configured the environment variables as follows:

export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890

export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890

export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890

export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890

However, I found that the program does not use the system proxy.

I hope that worker fetch will use the specified HTTP proxy to make API requests.

Because some content requires using http_proxy to access.

Interesting, it should be saying Proxy environment variables detected. We'll use your proxy for fetch requestsProxy environment variables detected. We'll use your proxy for fetch requests if it picked it up. You're using local mode and not remote right?

ahh looks like you already opened a issue on workers-sdk

I was investigating this because my application requires proxying for auditing purposes. I couldn't figure out how to have the

fetch

fetch

of a page function use http_proxyhttp_proxy correctly. This leads me to believe it is not supported at all.
