A .http file is used to describe what will be send to a HTTP service, it's more convenient than cURL command, vscode has a great plugin named REST Client, it extend .http file with addition features, such as

• variable repalce
• named request
• reference value from named request
• and more ...

with these features, user can express more complex business logic, for example

1. user login
2. refer the auth information after step 1, to check the user's profile

# @name login
POST {{server}}/login
Content-Type: application/json

{
    "name": "",
    "password": "",
}


###

POST {{server}}/profile
Content-Type: application/json

{
    "auth": "{{login.response.body.$.auth}}",
    "kind": "all"
}

more information can be found in REST Client

usually, in service development state, we write .http files to test our service, after development stage, these files can also be used as test cases, test cases should be executed by machine instead human round by round, ftab is a tool to execute the .http file.

benchmark is also important for serivce, ftab can execute .http file with requests and currency like ab do with URL. for example

> ftab -i order.http -n 10000 -c 200
Total Requests      : 10,000
Currency            : 200
Successed           : 10,000
Failed              : 0
