Implementing a transport in C++ about sentry-native HOT 4 CLOSED

The URL in the post above does not seem to work, anymore, here is an updated one: https://develop.sentry.dev/sdk/overview/#parsing-the-dsn
The envelope docs also give you the POST url: https://develop.sentry.dev/sdk/envelopes

You have to parse the DSN and extract the authentication header from that yourself, as well as to create the actual envelope url from it. That functionality is unfortunately not exposed publicly from the SDK.

You can use sentry_options_set_transport to specify your own transport, and sentry_new_function_transport to create a very simple callback-based transport.

You use it like this:

        sentry_options_set_transport(
            options, sentry_new_function_transport(print_envelope, NULL));

All you can do right now with that envelope is to serialize it to a string, and then send it as a Content-Type: application/x-sentry-envelope to the store endpoint. See https://docs.sentry.io/development/sdk-dev/overview/#parsing-the-dsn for more details.

We are thinking about maybe exposing the internal sentry__envelope_for_each_request method in the future to make this a bit simpler for external users.

I hope this answers your question. Feel free to reopen.

@Swatinem how do I exactly send the serialized envelope information to required DSN? Suppose my DSN looks like - https://[email protected]/123, do I send a post request to it?
And how do I send the data I get from char* s = sentry_envelope_serialize(envelope, &size_out);? I see it's something like -

{"dsn": "...", "event_id": ""}
{"type":"event","length":...}
{"event_id":"...",.................................................}

From the previous comment, I notice I've to set Content-Type: application/x-sentry-envelope header but don't know about the string(containing 3 separate JSON) above.

For now, I've tried sending POST and PUT request to above DSN URL, with mentioned header set and that entire thing as raw string in body. The response I get is 404.

@Swatinem thanks! you correctly identified the problem of URL not working, thanks for providing the updated URL. I also managed to figure everything out by going through the sentry_example.c and putting curl_verbose = 1 😄
