dot-http

dot-http is a text-based scriptable HTTP client. It is a simple language that resembles the actual HTTP protocol but with just a smidgen of magic to make it more practical for someone who builds and tests APIs.

Installation

Script

Enter the following in a command prompt:

curl -LSfs https://japaric.github.io/trust/install.sh | sh -s -- --git bayne/dot-http

Binary releases

The easiest way for most users is simply to download the prebuilt binaries. You can find binaries for various platforms on the release page.

Cargo

First, install cargo. Then:

$ cargo install dot-http

You will need to use the stable release for this to work; if in doubt run

rustup run stable cargo install dot-http

Usage

See dot-http --help for usage.

Vim

See this plugin to use dot-http within vim.

The request

The request format is intended to resemble HTTP as close as possible. HTTP was initially designed to be human-readable and simple, so why not use that?

simple.http

GET http://httpbin.org
Accept: */*

Executing that script just prints the response to stdout:

$ dot-http simple.http
GET http://httpbin.org/get

HTTP/1.1 200 OK
access-control-allow-credentials: true
access-control-allow-origin: *
content-type: application/json
date: Sat, 18 Jan 2020 20:48:50 GMT
referrer-policy: no-referrer-when-downgrade
server: nginx
x-content-type-options: nosniff
x-frame-options: DENY
x-xss-protection: 1; mode=block
content-length: 170
connection: keep-alive

{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Host": "httpbin.org"
  },
  "url": "https://httpbin.org/get"
}

Variables

Use variables to build the scripts dynamically, either pulling data from your environment file or from a previous request's response handler.

simple_with_variables.http

POST http://httpbin.org/post
Accept: */*
X-Auth-Token: {{token}}

{
    "id": {{env_id}}
}

http-client.env.json

{
    "dev": {
        "env_id": 42,
        "token": "SuperSecretToken"
    }
}

Note that the variables are replaced by their values

$ dot-http simple_with_variables.http
POST http://httpbin.org/post

HTTP/1.1 200 OK
access-control-allow-credentials: true
access-control-allow-origin: *
content-type: application/json
date: Sat, 18 Jan 2020 20:55:24 GMT
referrer-policy: no-referrer-when-downgrade
server: nginx
x-content-type-options: nosniff
x-frame-options: DENY
x-xss-protection: 1; mode=block
content-length: 342
connection: keep-alive

{
  "args": {},
  "data": "{\r\n    \"id\": 42\r\n}",
  "files": {},
  "form": {},
  "headers": {
    "Accept": "*/*",
    "Content-Length": "18",
    "Host": "httpbin.org",
    "X-Auth-Token": "SuperSecretToken"
  },
  "json": {
    "id": 42
  },
  "url": "https://httpbin.org/post"
}

Environment file

Use an environment file to control what initial values variables have

http-client.env.json

{
    "dev": {
        "host": localhost,
        "token": "SuperSecretToken"
    },
    "prod": {
        "host": example.com,
        "token": "ProductionToken"
    }
}

env_demo.http

GET http://{{host}}
X-Auth-Token: {{token}}

Specifying different environments when invoking the command results in different values for the variables in the script

$ dot-http -e dev env_demo.http
GET http://localhost
X-Auth-Token: SuperSecretToken

$ dot-http -e prod env_demo.htp
GET http://example.com
X-Auth-Token: ProductionToken

Response handler

Use previous requests to populate some of the data in future requests

response_handler.http

POST http://httpbin.org/post
Content-Type: application/json

{
    "token": "sometoken",
    "id": 237
}

> {%
   client.global.set('auth_token', response.body.json.token);
   client.global.set('some_id', response.body.json.id);
%}

###

PUT http://httpbin.org/put
X-Auth-Token: {{auth_token}}

{
    "id": {{some_id}}
}

Data from a previous request

$ dot-http test.http
POST http://httpbin.org/post

HTTP/1.1 200 OK
access-control-allow-credentials: true
access-control-allow-origin: *
content-type: application/json

server: nginx
x-content-type-options: nosniff
x-frame-options: DENY
x-xss-protection: 1; mode=block
content-length: 404
connection: keep-alive

{
  "args": {},
  "data": "{\r\n    \"token\": \"sometoken\",\r\n    \"id\": 237\r\n}",
  "files": {},
  "form": {},
  "headers": {
    "Accept": "*/*",
    "Content-Length": "46",
    "Content-Type": "application/json",
    "Host": "httpbin.org"
  },
  "json": {
    "id": 237,
    "token": "sometoken"
  },
  "url": "https://httpbin.org/post"
}
