How to use a Proxy and ca cert

[aphsa]

How will the code look like if I want to go through a Proxy:
In short what will be the equivalent of the following curl command using this library

curl --proxy "proxyhost:8888"  --cacert mitmproxy-ca-cert.cer  "https://example.com"

You would need to change the Transport. See https://github.com/earthboundkid/requests/wiki#validate-certificates for a hard coded cert example. Not sure about a cert proxy off the top of my head.

I end up using this method. Is there a better solution?

    // custom HTTP transport if proxy is enabled
    var transport *http.Transport
    if config.Proxy {
        transport = &http.Transport{
            Proxy: http.ProxyURL(&url.URL{
                Scheme: "http",
                Host:   config.Proxyhostport,
            }),
            TLSClientConfig: tlsConfig,
        }
    }

    // custom HTTP client with timeout
    client := &http.Client{
        Timeout: 15 * time.Second, 
    }
    if config.Proxy {
        client.Transport = transport
    }

    // Fetch the response 
    var body string
    err := requests.
        URL(config.URL).
        Header("Authorization", fmt.Sprintf("Bearer %s", config.APIKey)).
        Client(client).
        ToString(&body).
        Fetch(context.Background())
    if err != nil {
        return result, fmt.Errorf("failed to perform request: %w", err)
    }

There is a Bearer helper method, so you don’t need to do that manually, but the rest looks right.
