RTS: Request to Struct

GoDoc Build Status

Generate Go structs definitions from JSON server responses.

RTS defines type names using the specified lines in the route file and skipping numbers. e.g: a request to a route like /users/1/posts generates type UsersPosts

It supports parameters: a line like /users/:user/posts/:pid 1 200 generates type UsersUserPostsPid from the response to the request GET /users/1/posts/200.

RTS supports headers personalization as well, thus it can be used to generate types from responses protected by some authorization method

Install

CLI Application

go get -u github.com/galeone/rts/cmd/rts

CLI Usage

rts [options]
  -headers string
    	Headers to add in every request
  -help
    	prints this help
  -insecure
    	Disables TLS Certificate check for HTTPS, use in case HTTPS Server Certificate is signed by an unknown authority
  -out string
    	Output file. Stdout is used if not specified
  -pkg string
    	Package name (default "main")
  -routes string
    	Routes to request. One per line (default "routes.txt")
  -server string
    	sets the server address (default "http://localhost:9090")
  -substruct
    	Creates types for sub-structs

Examples

You can invoke rts piping from stdin a single JSON (anonymous) and get it converted to a go structure

echo '  {
    "Book Id": 30558257,
    "Title": "Unsouled (Cradle, #1)",
    "Author": "Will Wight",
    "Author l-f": "Wight, Will",
    "Additional Authors": "",
    "BCID": ""
  }' | ./rts

obtaining

package main

type Foo1 struct {
        Additional_Authors string `json:"Additional Authors"`
        Author             string `json:"Author"`
        Author_l_f         string `json:"Author l-f"`
        Bcid               string `json:"BCID"`
        Book_Id            int64  `json:"Book Id"`
        Title              string `json:"Title"`
}

Or you can define a more complex scenario, definining the routes.txt file with a line for each (parametric) request and use it as shown below.

routes.txt:

/
/repos/:user/:repo galeone igor

Run:

rts -server https://api.github.com -pkg example

Returns:
