RTS: Request to Struct
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:
