go-rip

Small library for making json rest calls. go-rip provides fluent chainable api that makes doing rest calls reslly simple.

name

Why the name? Well rest in peace fits quite good as rest api client.

Install

You can install this library simply by typing:

go get github.com/phonkee/go-rip

Examples:

Let's see this library in action. First let's create a client that we will use in all examples

client := rip.New("http://127.0.0.1/api/v1")

Client has even more methods to add:

• Headers - add default headers for all method calls
• AppendSlash - add trailing slash if not presented
• Base - set base url
• Client - set custom http.Client instead of default ones
• Data - add data to be sent as body, data can be:
  • string - is converted to []byte
  • byte[] - sent as is
  • other - will be json Marshalled to []byte
• Path - add path prefix
• QueryValues - add query values (query parameters)
• UserAgent - set custom user agent instead of default one

Now let's make a http GET request.

type Product struct {}

product = Product{}
status := 0
if err := client.Get("product", 1).Do(context.Background(), &product).Status(&status).Error(); err != nil {
    panic("oops")
}

This makes a http GET call to "http://127.0.0.1/api/v1/product/1/" and unmarshals result to product variable. We are also handling errors and filling status variable with http status code in the same line. Isn't that nice?

You can see that go-rip uses golangs context for http requests and must be passed as first argument to Do method.

Let's make a POST request with some data.

product = Product{}
result = map[string]interface{}
if err := client.Post("product", 1).Data(product).Do(context.Background(), &result).Error(); err != nil {
    panic(err)
}

We just made http POST request to "http://127.0.0.1/api/v1/product/1/" and we sent body of the request json marshalled product. Ain't that really nice?
