 # Guide to run Gin under App Engine LOCAL Development Server
 1. Download, install and setup Go in your computer. (That includes setting your `$GOPATH`.)
 2. Download SDK for your platform from [here](https://cloud.google.com/appengine/docs/standard/go/download): `https://cloud.google.com/appengine/docs/standard/go/download`
 3. Download Gin source code using: `$ go get github.com/gin-gonic/gin`
 4. Navigate to examples folder: `$ cd $GOPATH/src/github.com/gin-gonic/gin/examples/app-engine/`
 5. Run it: `$ dev_appserver.py .` (notice that you have to run this script by Python2)

 # Building a single binary containing templates
 This is a complete example to create a single binary with the
 [gin-gonic/gin][gin] Web Server with HTML templates.
 [gin]: https://github.com/gin-gonic/gin
 ## How to use
 ### Prepare Packages
 ```
 go get github.com/gin-gonic/gin
 go get github.com/jessevdk/go-assets-builder
 ```
 ### Generate assets.go
 ```
 go-assets-builder html -o assets.go
 ```
 ### Build the server
 ```
 go build -o assets-in-binary
 ```
 ### Run
 ```
 ./assets-in-binary
 ```

 ## How to generate RSA private key and digital certificate
 1. Install Openssl
 Please visit https://github.com/openssl/openssl to get pkg and install.
 2. Generate RSA private key
 ```sh
 $ mkdir testdata
 $ openssl genrsa -out ./testdata/server.key 2048
 ```
 3. Generate digital certificate
 ```sh
 $ openssl req -new -x509 -key ./testdata/server.key -out ./testdata/server.pem -days 365
 ```

 The [New Relic Go Agent](https://github.com/newrelic/go-agent) provides a nice middleware for the stdlib handler signature. 
 The following is an adaptation of that middleware for Gin.
 ```golang
 const (
 	// NewRelicTxnKey is the key used to retrieve the NewRelic Transaction from the context
 	NewRelicTxnKey = "NewRelicTxnKey"
 )
 // NewRelicMonitoring is a middleware that starts a newrelic transaction, stores it in the context, then calls the next handler
 func NewRelicMonitoring(app newrelic.Application) gin.HandlerFunc {
 	return func(ctx *gin.Context) {
 		txn := app.StartTransaction(ctx.Request.URL.Path, ctx.Writer, ctx.Request)
 		defer txn.End()
 		ctx.Set(NewRelicTxnKey, txn)
 		ctx.Next()
 	}
 }
 ```
 and in `main.go` or equivalent...
 ```golang
 router := gin.Default()
 cfg := newrelic.NewConfig(os.Getenv("APP_NAME"), os.Getenv("NEW_RELIC_API_KEY"))
 app, err := newrelic.NewApplication(cfg)
 if err != nil {

 ## Struct level validations
 Validations can also be registered at the `struct` level when field level validations
 don't make much sense. This can also be used to solve cross-field validation elegantly.
 Additionally, it can be combined with tag validations. Struct Level validations run after
 the structs tag validations.
 ### Example requests
 ```shell
 # Validation errors are generated for struct tags as well as at the struct level
 $ curl -s -X POST http://localhost:8085/user \
 	-H 'content-type: application/json' \
 	-d '{}' | jq
 {
  "error": "Key: 'User.Email' Error:Field validation for 'Email' failed on the 'required' tag\nKey: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag\nKey: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag",
  "message": "User validation failed!"
 }
 # Validation fails at the struct level because neither first name nor last name are present
 $ curl -s -X POST http://localhost:8085/user \
    -H 'content-type: application/json' \
 	-d '{"email": "george@vandaley.com"}' | jq
 {
  "error": "Key: 'User.FirstName' Error:Field validation for 'FirstName' failed on the 'fnameorlname' tag\nKey: 'User.LastName' Error:Field validation for 'LastName' failed on the 'fnameorlname' tag",
  "message": "User validation failed!"
 }
 # No validation errors when either first name or last name is present
 $ curl -X POST http://localhost:8085/user \
    -H 'content-type: application/json' \
 	-d '{"fname": "George", "email": "george@vandaley.com"}'
 {"message":"User validation successful."}
 $ curl -X POST http://localhost:8085/user \
    -H 'content-type: application/json' \
 	-d '{"lname": "Contanza", "email": "george@vandaley.com"}'
 {"message":"User validation successful."}
 $ curl -X POST http://localhost:8085/user \
    -H 'content-type: application/json' \
 	-d '{"fname": "George", "lname": "Costanza", "email": "george@vandaley.com"}'
 {"message":"User validation successful."}
