Request methods of Gofiber HTTP client.

---
The `Request` structure in Gofiber's HTTP client represents an HTTP request. It encapsulates all the necessary information needed to send a request to a server, including:
- **URL**: The endpoint to which the request is sent.
- **Method**: The HTTP method (GET, POST, PUT, DELETE, etc.).
- **Headers**: Key-value pairs that provide additional information about the request or guide how the response should be processed.
- **Body**: The data sent with the request, commonly used with methods like POST and PUT.
- **Query Parameters**: Parameters appended to the URL to pass additional data or modify the request's behavior.
This structure is designed to be both flexible and efficient, allowing you to easily build and modify HTTP requests as needed.
```go
type Request struct {
url string
method string
userAgent string
boundary string
referer string
ctx context.Context
header *Header
params *QueryParam
cookies *Cookie
path *PathParam
timeout time.Duration
maxRedirects int
client *Client
body any
formData *FormData
files []*File
bodyType bodyType
RawRequest *fasthttp.Request
}
```
## REST Methods
### Get
**Get** sends a GET request to the specified URL. It sets the URL and HTTP method, then dispatches the request to the server.
```go title="Signature"
func (r *Request) Get(url string) (*Response, error)
```
### Post
**Post** sends a POST request. It sets the URL and method to POST, then sends the request.
```go title="Signature"
func (r *Request) Post(url string) (*Response, error)
```
### Put
**Put** sends a PUT request. It sets the URL and method to PUT, then sends the request.
```go title="Signature"
func (r *Request) Put(url string) (*Response, error)
```
### Patch
**Patch** sends a PATCH request. It sets the URL and method to PATCH, then sends the request.
```go title="Signature"
func (r *Request) Patch(url string) (*Response, error)
```
### Delete
**Delete** sends a DELETE request. It sets the URL and method to DELETE, then sends the request.
```go title="Signature"
func (r *Request) Delete(url string) (*Response, error)
```
### Head
**Head** sends a HEAD request. It sets the URL and method to HEAD, then sends the request.
```go title="Signature"
func (r *Request) Head(url string) (*Response, error)
```
### Options
**Options** sends an OPTIONS request. It sets the URL and method to OPTIONS, then sends the request.
```go title="Signature"
func (r *Request) Options(url string) (*Response, error)
```
### Custom
**Custom** sends a request using a custom HTTP method. For example, you can use this to send a TRACE or CONNECT request.
```go title="Signature"
func (r *Request) Custom(url, method string) (*Response, error)
```
## AcquireRequest
**AcquireRequest** returns a new (pooled) `Request` object. When you are done with the request, call `ReleaseRequest` to return it to the pool and reduce GC load.
```go title="Signature"
func AcquireRequest() *Request
```
## ReleaseRequest
**ReleaseRequest** returns the `Request` object back to the pool. Do not use the request after releasing it, as this may cause data races.
```go title="Signature"
func ReleaseRequest(req *Request)
```
## Method
**Method** returns the current HTTP method set for the request.
```go title="Signature"
func (r *Request) Method() string
```
## SetMethod
**SetMethod** sets the HTTP method for the `Request` object. Typically, you should use the specialized request methods (`Get`, `Post`, etc.) instead of calling `SetMethod` directly.
```go title="Signature"
func (r *Request) SetMethod(method string) *Request
```
## URL
**URL** returns the current URL set in the `Request`.
```go title="Signature"
func (r *Request) URL() string
```
## SetURL
**SetURL** sets the URL for the `Request` object.
```go title="Signature"
func (r *Request) SetURL(url string) *Request
```
## Client
**Client** retrieves the `Client` instance associated with the `Request`.
```go title="Signature"
func (r *Request) Client() *Client
```
## SetClient
**SetClient** assigns a `Client` to the `Request`. If the provided client is `nil`, it will panic.
```go title="Signature"
func (r *Request) SetClient(c *Client) *Request
```
## Context
**Context** returns the `context.Context` of the request, or `context.Background()` if none is set.
```go title="Signature"
func (r *Request) Context() context.Context
```
## SetContext
**SetContext** sets the `context.Context` for the request, allowing you to cancel or time out the request. See the [Go blog](https://blog.golang.org/context) and [context](https://pkg.go.dev/context) docs for more details.
```go title="Signature"
func (r *Request) SetContext(ctx context.Context) *Request
```
## Header
**Header** returns all values for the specified header key. It searches all header fields stored in the request.
```go title="Signature"
func (r *Request) Header(key string) []string
```
### Headers
**Headers** returns an iterator over all headers in the request. Use `maps.Collect()` to transform them into a map if needed. The returned values are valid only until the request is released. Make copies as required.
```go title="Signature"
func (r *Request) Headers() iter.Seq2[string, []string]
```
Example
```go title="Example"
req := client.AcquireRequest()
req.AddHeader("Golang", "Fiber")
req.AddHeader("Test", "123456")
req.AddHeader("Test", "654321")
for k, v := range req.Headers() {
fmt.Printf("Header Key: %s, Header Value: %v\n", k, v)
}
```
```sh
Header Key: Golang, Header Value: [Fiber]
Header Key: Test, Header Value: [123456 654321]
```

req.AddHeader("Golang", "Fiber")
req.AddHeader("Test", "123456")
req.AddHeader("Test", "654321")

for k, v := range headers {
fmt.Printf("Header Key: %s, Header Value: %v\n", k, v)
}
```
```sh
Header Key: Golang, Header Value: [Fiber]
