Maintainers

This provider plugin is maintained by the sal, just sal for now.

Requirements

• Terraform 0.14.x
• Go 1.15 (to build the provider plugin)

Usage

This provider is published here:

• https://registry.terraform.io/providers/salrashid123/http-full/latest

terraform {
  required_providers {
    http-full = {
      source = "salrashid123/http-full"
    }
  }
}

provider "http-full" {}
 
# HTTP POST 
data "http" "example" {
  provider = http-full
  url = "https://httpbin.org/post"

  method = "POST"

  request_headers = {
    content-type = "application/json"
  }
  request_body = jsonencode({
    foo = "bar",
    bar = "bar"
  })
}

output "data" {
  value = jsondecode(data.http.example.body)
}


# mTLS
data "http" "example" {
  provider = http-full
  url = "https://localhost:8081/get"

  method = "GET"

  ca = file("${path.module}/../certs/CA_crt.pem")
  client_crt = file("${path.module}/../certs/client.crt")
  client_key = file("${path.module}/../certs/client.key")  
}

You can also use this to interact with an STS server to get any auth token.

data "http" "sts" {
  provider = http-full

  url = "https://stsserver-6w42z6vi3q-uc.a.run.app/token"

  method = "POST"
  request_headers = {
    content-type = "application/json"
  }
  request_body = jsonencode({
    grant_type = "urn:ietf:params:oauth:grant-type:token-exchange",
    resource = "grpcserver-6w42z6vi3q-uc.a.run.app",
    audience = "grpcserver-6w42z6vi3q-uc.a.run.app",
    requested_token_type = "urn:ietf:params:oauth:token-type:access_token",
    subject_token = "iamtheeggman",
    subject_token_type = "urn:ietf:params:oauth:token-type:access_token"
  })
}

output "sts_token" {
  value = jsondecode(data.http.sts.body).access_token
}

The default mode will be POST with application/json. To POST as application/x-www-form-urlencoded:

data "http" "example_form" {
  provider = http-full
  url = "https://httpbin.org/post"

  method = "POST"

  request_headers = {
    content-type = "application/x-www-form-urlencoded"
  }
  request_body = "foo=bar&bar=bar"
}

For mTLS and other configurations, see example/index.md

Building the DEV Provider

Clone repository to: `$GOPATH/src/github.com/salrashid123/terraform-provider-http-full

mkdir -p $GOPATH/src/github.com/terraform-providers
cd $GOPATH/src/github.com/terraform-providers
git clone https://github.com/salrashid123/terraform-provider-http-full.git

Enter the provider directory and build the provider

cd $GOPATH/src/github.com/terraform-providers/terraform-provider-http-full
make fmt
make build

Using the DEV provider

Copy the provider to your directory

mkdir -p ~/.terraform.d/plugins/registry.terraform.io/salrashid123/http-full/5.0.0/linux_amd64/
cp $GOBIN/terraform-provider-http-full ~/.terraform.d/plugins/registry.terraform.io/salrashid123/http-full/5.0.0/linux_amd64/terraform-provider-http-full_v5.0.0

Then

cd example
terraform init

terraform apply

with

terraform {
  required_providers {
    http-full = {
      source  = "registry.terraform.io/salrashid123/http-full"
      version = "~> 5.0.0"
    }
  }
}

provider "http-full" {
}
 
data "http" "example" {
  provider = http-full
  url = "https://httpbin.org/post"

  method = "POST"
  request_headers = {
    content-type = "application/json"
  }
  request_body = jsonencode({
    foo = "bar"
    bar = "bar"
  })
}

output "data" {
  value = jsondecode(data.http.example.body)
}

...

In order to test the provider, you can simply run make test.

TEST

$ make test
