# XML-RPC Client for Go
|
|
|
|
This is an implementation of client-side part of XML-RPC protocol in Go.

|
|
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
Add dependency to your project:
|
|
|
|
```shell
|
|
go get -u alexejk.io/go-xmlrpc
|
|
```
|
|
|
|
Use it by creating an `*xmlrpc.Client` and firing RPC method calls with `Call()`.
|
|
|
|
```go
|
|
package main
|
|
|
|
import(
|
|
"fmt"
|
|
|
|
"alexejk.io/go-xmlrpc"
|
|
)
|
|
|
|
func main() {
|
|
client, _ := xmlrpc.NewClient("https://bugzilla.mozilla.org/xmlrpc.cgi")
|
|
|
|
result := &struct {
|
|
BugzillaVersion struct {
|
|
Version string
|
|
}
|
|
}{}
|
|
|
|
_ = client.Call("Bugzilla.version", nil, result)
|
|
fmt.Printf("Version: %s\n", result.BugzillaVersion.Version)
|
|
}
|
|
```
|
|
|
|
Customization is supported by passing a list of `Option` to the `NewClient` function.
|
|
For instance:
|
|
|
|
- To customize any aspect of `http.Client` used to perform requests, use `HttpClient` option, otherwise `http.DefaultClient` will be used
|
|
- To pass custom headers, make use of `Headers` option.
|
|
|
|
### Argument encoding
|
|
|
|
Arguments to the remote RPC method are passed on as a `*struct`. This struct is encoded into XML-RPC types based on following rules:
|
|
|
|
* Order of fields in struct type matters - fields are taken in the order they are defined on the **type**.
|
|
* Numbers are to be specified as `int` (encoded as `<int>`) or `float64` (encoded as `<double>`)
|
|
* Both pointer and value references are accepted (pointers are followed to actual values)
|
|
|
|
### Response decoding
|
|
|
|
Response is decoded following similar rules to argument encoding.
|
|
|
|
* Order of fields is important.
|
|
* Outer struct should contain exported field for each response parameter.
|
|
* Structs may contain pointers - they will be initialized if required.
|

## Building
|
|
|
|
To build this project, simply run `make all`.
|
|
If you prefer building in Docker instead - `make build-in-docker` is your friend.
