swampi is a golang client for the swarm http api, and enables programmatic access to the swarm API via your golang programs. It's primary purpose is for use with Temporal, but other users may find it useful.
Individual API calls are represented by a typed string call APICall. This allows reducing code surface for common task such as request handling, request formatting, etc..
The value of APICall instances is the actual HTTP path for the API call. For example single file upload is stored in code as APICall("/bzz:/"), so APICall::String will return the http path to be fed into http.NewRequest. Additionally methods like APICall::ContentType mean you don't have to deal with guessing the content type for requests as its done for you. Additionally certain API calls require url arguments, such as the single file download which takes the swarm hash. These are handled with APICall::ParseArgs.
For more detailed usage instructions see the tests, but in essence it consists of:
// this creates our swampi client
swampi := New("http://localhost:8500")
fileBytes, err := ioutil.ReadFile(tt.args.filePath)
if err != nil {
log.Fatal(err)
}
// handles parsing the api calls and sending it, returning the response
resp, err := swampi.Send(SingleFileUpload, bytes.NewReader(fileBytes), map[string][]string{
"content-type": []string{SingleFileUpload.ContentType()},
})
if err != nil {
log.Fatal(err)
}
// do stuff with response
