Kill Bill go client library and kill bill command line

This repository contains killbill go client library (kbclient) and killbill command line tool (kbcmd)

Versions

KB Version KBCli Version
0.20.x 1.x.y
0.22.x 2.x.y

Kill bill go client library

Kill bill go client library is a go package that can be used to connect to kill bill.

Install

go get -u github.com/killbill/kbcli/v2

Creating new client

    trp := httptransport.New("127.0.0.1:8080", "", nil)
    // Add text/xml producer which is not handled by openapi runtime.
    trp.Producers["text/xml"] = runtime.TextProducer()
    // Set this to true to dump http messages
    trp.Debug = false
    // Authentication
    authWriter := runtime.ClientAuthInfoWriterFunc(func(r runtime.ClientRequest, _ strfmt.Registry) error {
        encoded := base64.StdEncoding.EncodeToString([]byte("admin"/*username*/ + ":" + "password" /**password*/))
        if err := r.SetHeaderParam("Authorization", "Basic "+encoded); err != nil {
            return err
        }
        if err := r.SetHeaderParam("X-KillBill-ApiKey", apiKey); err != nil {
            return err
        }
        if err := r.SetHeaderParam("X-KillBill-ApiSecret", apiSecret); err != nil {
            return err
        }
        return nil
    })
    client := kbclient.New(trp, strfmt.Default, authWriter, kbclient.KillbillDefaults{})

Look at the complete example here. For more examples, look at kbcmd tool.

Client code generation

This client code was generated by the go-swagger tool.

We use a modified generator and templates to generate the client, and the sources are here.

As explained in the commit, we are stuck on an older version of go-swagger, i.e our fork is not up to date with parent. In addition to this, there is an issue compiling the tool with recent version of go, and so we are aldo currently stuck using go <= 1.13 -- for building the tool itself, i.e the swagger generator.

To download/install GO 1.13, follow the steps from here, or simply:

# This will install the tool under  ~/sdk by default
go get golang.org/dl/go1.13
go1.13 download

# You can then set GOROOT=~/sdk/go1.13 in your shell or inside Goland 's preference (for the project)

To build the (custom) swagger generator

# Pre-requisite (needed if template changes)
brew install go-bindata

# Install swagger tool
mkdir -p $GOPATH/src/github.com/go-swagger
cd $GOPATH/src/github.com/go-swagger
git clone git@github.com:killbill/go-swagger.git

# Each time the templates change, following 2 steps are needed:

#1. Regenerate the (template) byte code inside the go-swagger code itself ->  generator/bindata.go should be modified
go1.13 generate ./generator

#2. build the binary
go1.13 build cmd/swagger/swagger.go && cp swagger cp ./swagger $GOPATH/bin/swagger

Finally, in order to generate the killbill client (using the custom swagger generator):

# Update swagger.json
curl http://localhost:8080/swagger.json | jq "." >swagger.json

# Regenerate the tool
swagger generate client -f swagger.json -m kbmodel -c kbclient --default-scheme=http

Generating dev extensions

We also have dev extension APIs (like clock etc), that are in swagger-dev.json. To generate, run the following.

# Regenerate the tool
swagger generate client -f swagger-dev.json -m kbmodel -c kbclient --default-scheme=http

# Delete the client file.
rm kbclient/kill_bill_dev_client.go

Kill bill command line tool (kbcmd)

kbcmd is a command line tool that uses the go client library. This tool can do many of the kill bill operations. More details are available here in README.
