#GOLANG HTTP CLIENT CODE#
This one in my experience really can do 100%, but obviously, the more complicated the case, the less you benefit per se from having a library, since eventually your code ends up being huge no matter what. Programs that must disable HTTP/2 can do so by setting Transport.TLSNextProto (for clients) or Server.TLSNextProto (for servers) to a non-nil, empty map. The built in options are to validate by status and content type, but I often will write thing to peek at the first couple of bytes of a response to make sure it's the content type I expect, see here: įor validation, it's hard to say in general because every API is different, but in general distinguishing an error JSON struct from a normal JSON struct can be handled in an UnmarshalJSON method, like I did just last week for Google Maps API: That API is kind of funky and old though, so it doesn't actually use correct HTTP status responses.īasically every other requests library I found was only good for 80% of cases. Starting with Go 1.6, the http package has transparent support for the HTTP/2 protocol when using HTTPS. The Session object contains the HTTP interface methods and an authentication object that provides access to the auth token and service catalog. The Builder type has an AddValidator method and a Validator can be anything that takes a response and spits out an error, so the exact way it works it up to you. NOTE(dtroyer) Apr 2015: This repo is under heavy revision as it is being revived. I would like to write the Go implementation for internal use. There is language support of Python/NodeJs/Java/C. In general, there is a lot of stuff in the Go ecosystem that works with custom http.Clients/http.RoundTrippers: oauth 1 and 2, backoff retries, etc. Our organization introduced a tool which supports REST. "Reauthenticating" implies you're doing something like Oauth where you have to fetch tokens from somewhere, and for that there are drop-in custom http.Client you can use already. Linkrot isn't per se complicated because it's just checking for dead links, but it does end up parsing the HTML and doing a lot that I haven't seen attempted outside of something like Colley (which didn't exist when the first version of linkrot was written). It prints headers and optionally measures response time and needs to use a custom client to get IP addresses and a lot of weird stuff.
Validate cookie and headers are attachedįmt.Println("response Status:", resp.Status)įmt.Println("response Headers:", resp.Get-headers is a good example of something that is more than just a simple JSON getter.

#GOLANG HTTP CLIENT HOW TO#
This example demonstrates how to set the client request timeout and headers. It reads the entire response body to a variable named body and then prints it to standard output: package main And if the connection is lost, the client will automatically try. This minimal example uses http.Get from the net/http standard library package. In case the WebSocket connection is not possible, it will fall back to HTTP long-polling. While Add appends to any existing values associated with key, Set replaces any existing values associated with key. The net/http package has many functions that handle headers, those include the Add, Del, Get and Set methods. dependent packages 1,293 total releases 33. Simple HTTP and REST client library for Go. Using the minimal http.Get functionality can work for quick programs but you may find that you need more features, such as setting timeout values or adding headers.
