# Request

simple golang package for making API requests

## Documentation

Documentation for the project can be found on [pkg.go.dev](https://pkg.go.dev/git.0cd.xyz/michael/request/?tab=doc)

## Installation

With a correctly configured golang toolchain:

```sh
go get -u git.0cd.xyz/michael/request
```

## Examples

Requesting and encoding structured data:

```go
type Topics struct {
    TopicList struct {
        Topics []struct {
            ID         int    `json:"id"`
            Title      string `json:"title"`
            PostsCount int    `json:"posts_count"`
            CreatedAt  string `json:"created_at"`
            Slug       string `json:"slug"`
        } `json:"topics"`
    } `json:"topic_list"`
}

func topics() (topics *Topics, err error) {
    headers := map[string]string{
        "Accept":       "application/json",
        "Content-Type": "application/json",
    }
    resp, err := request.API(http.MethodGet, "https://forum.0cd.xyz/t/nixos-vfio-pcie-passthrough/277", headers, nil)
    if err != nil {
        return nil, err
    }
    err = json.Unmarshal(resp.Body, &topics)
    if err != nil {
        return nil, err
    }
    return topics, nil
}
```

Requesting and encoding unstructured data:

```go
users := make(map[string]interface{})
headers := map[string]string{
    "Accept":       "application/json",
    "Content-Type": "application/json",
}

resp, err := API(http.MethodGet, "https://reqres.in/api/users", headers, nil)
if err != nil {
    log.Println(err)
    return
}

err = json.Unmarshal(resp.Body, &users)
if err != nil {
    log.Println(err)
    return
}

fmt.Println(users["data"])
```

Asynchronous API requests:

```go
func topics(urls []string) (topicBody [][]byte, error err) {
    headers := map[string]string{
    "Accept":       "application/json",
    "Content-Type": "application/json",

    ch := make(chan *request.Response)
    var wg sync.WaitGroup

    for _, path := range urls {
        wg.Add(1)
        go request.AsyncAPI(http.MethodGet, path, headers, nil, ch, &wg)
    }

    go func() {
        wg.Wait()
        close(ch)
    }()

    for resp := range ch {
        if resp.Error != nil {
            return err
        }
        topicBody = append(topicBody, resp.Body)
    }
    return topicBody, nil
}
```

Sending requests with data using post, put, etc:

```go
headers := map[string]string{
    "Accept":       "application/json",
    "Content-Type": "application/json",
}

req := `{
    "on": true,
    "bri": 255
}`

_, err := request.API(http.MethodPut, "http://10.0.40.2/api/<apikey>/lights/4/state", headers, bytes.NewBuffer([]byte(req)))
if err != nil {
    log.Println(err)
}
```
