Primary LanguageGoMIT LicenseMIT

#go-json-rest-middleware-formjson Provides "x-www-form-urlencoded" to "json" conversion middleware for go-json-rest

Explanation

This package provides a Go-Json-Rest middleware useful for converting request data with the content type "application/x-www-form-urlencoded" to "application/json"

Note: Use BEFORE ContentTypeCheckerMiddleware in cases where x-www-form-urlencoded data must be handled

If "Content-Type" Header set to "x-www-form-urlencoded":

  • Changes header "Content-Type" from "application/x-www-form-urlencoded" to "application/json"
  • Converts body from var1=val1&var2=val2 to {"var1":"val1","var2":"val2"}

Installation

go get github.com/boonep/go-json-rest-middleware-formjson

Usage

Example 1

Check for Content-Type application/x-www-form-urlencoded on all routes, and convert to application/json

api.Use([]rest.Middleware{
	&formjson.Middleware{},
	&rest.ContentTypeCheckerMiddleware{},
}...)

Example 2

Only check specific path and method. This will be the most likely use case. You should use json content wherever possible, but if you MUST interact with form data on a specific endpoint, you can handle it this way.

formJsonMiddleware := &formJson.MiddleWare{}

api.Use(&rest.IfMiddleware{
	Condition: func(request *rest.Request) bool {
		return request.URL.Path == "/form-data" && request.Method == "POST"
	},
	IfTrue: &formjson.Middleware{},
})

api.Use([]rest.Middleware{
	&rest.ContentTypeCheckerMiddleware{},
}...)

Above will only convert form content on a POST request to the "/form-data" path

Notes

This middleware performs basic functionality for our specific use case (interact with a 3rd party SAAS solution that could not provide JSON content). Feel free to improve and submit pull requests. Thanks!
