![]() Then, you will expand that program to run multiple HTTP servers in the same program.īefore you write any code, though, you’ll need to get your program’s directory created. In this section, you will create a program that uses the http.ListenAndServe function to start an HTTP server that responds to the request paths / and /hello. The net/http package not only includes the ability to make HTTP requests, but also provides an HTTP server you can use to handle those requests. In Go, most of the HTTP functionality is provided by the net/http package in the standard library, while the rest of the network communication is provided by the net package. Familiarity with how HTTP requests are composed and sent (recommended).Experience running goroutines and reading channels, which can be gained from the tutorial, How To Run Multiple Functions Concurrently in Go.Experience with Go’s context package, which can be attained in the tutorial, How To Use Contexts in Go. ![]() Familiarity with using JSON in Go, which can be found in the How To Use JSON in Go tutorial.To read up on curl, check out How To Download Files with cURL. Ability to use curl to make web requests.To set this up, follow the How To Install Go tutorial for your operating system. You’ll also update your program to respond to the request with your own HTTP headers and status codes. In this tutorial, you will create an HTTP server using Go’s standard library and then expand your server to read data from the request’s query string, the body, and form data. The Go standard library provides built-in support for creating an HTTP server to serve your web content or making HTTP requests to those servers. The Hypertext Transfer Protocol (HTTP) serves much of this content, whether it’s a request for a cat image or a request to load the tutorial you’re reading now. Many developers spend at least some of their time creating servers to distribute content on the internet. Following is the nginx config.The author selected the Diversity in Tech Fund to receive a donation as part of the Write for DOnations program. When request comes, nginx verifies the client certificate(weather it issued by the given CA). Then I need to configure nginx server to verify the client certificates. # client key out to temp.key openssl rsa -in client.key -out temp.key # remove client.key rm client.key # make temp.key as client key mv temp.key client.key 2. In here I’m copying the content of server and client key to temp file and making the temp as the key # server key out to temp.key openssl rsa -in server.key -out temp.key # remove server.key rm server.key # make temp.key as server key mv temp.key server.keyīy same way I’m removing the pass phrase of the client key. I’m removing that pass phrase from the key, then I can use the key without the password. We need to specify that password when loading the key(in nginx and golang http client). When generating server key and client key, its asking for a password. # sign client CSR with CA certificate and key openssl x509 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt 1.6 Remove pass phrase from server and client keys Generated certificate signing request(CSR) need to be signed by CS’s certificate/key to obtain the client certificate. # client key openssl genrsa -des3 -out client.key 1024 # CSR to obtain certificate openssl req -new -key client.key -out client.csr 1.5 Generate client certificate ![]() ![]() Need to generate client key and certificate signing request(CSR) to obtain the client certificate. # sign server CSR with CA certificate and key openssl x509 -req -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt 1.4 Generate client Key and CSR ![]() Generated certificate signing request(CSR) need to be signed by CA’s certificate/key to obtain the server certificate. # server key openssl genrsa -des3 -out server.key 1024 # CSR (certificate sign request) to obtain certificate openssl req -new -key server.key -out server.csr 1.3 Generate server certificate Need to generate server key and certificate signing request(CSR) to obtain the server certificate. # CA key and certificate openssl genrsa -des3 -out ca.key 4096 openssl req -new -x509 -days 365 -key ca.key -out ca.crt 1.2 Generate server Key and CSR Generating CA Certificate/Key use to issue/sign the server and client certificates. I’m creating my own certificate authority(CA) to issue the certificates. Generate certificatesįirst of all I need to generate SSL certificates to client and server. Following are the steps that I have followed to achieve the mutual authentication between http client and http server. ![]()
