How to change which IP address a go-fiber client is using?
问题
我正在使用Fiber作为HTTP客户端向HTTP服务器发送请求，但是我遇到了速率限制的问题。在我的虚拟机上，我配置了5个不同的IP地址（公共/私有），并确认它们确实连接到了互联网。
curl --interface 10.0.0.4 ipinfo.io/json
curl --interface 10.0.0.5 ipinfo.io/json
...
curl --interface 10.0.0.8 ipinfo.io/json
每个命令返回一个不同的公共IP地址。
现在我想使用这些本地地址进行轮询请求，但是我不太确定如何操作。
是否有一种属性或函数可以设置/调用，以更改出站请求的来源？
我查看了fasthttp.HostClient，它是fiber.Agent的扩展，但是我没有找到有用的信息。
谢谢大家。

I'm using Fiber as an HTTP client to make some requests to an http server, however I'm being rate limited. On my vm I configured 5 different IP addresses (public/private) and have confirmed that they are indeed connected to the internet.
curl --interface 10.0.0.4 ipinfo.io/json
curl --interface 10.0.0.5 ipinfo.io/json
...
curl --interface 10.0.0.8 ipinfo.io/json
each one returns a different public facing ip address.
Now I'm interested in making round-robin requests using these local addresses but I'm not so sure how to go about it.
Is there some sort of property or function I can set/call to change where the outgoing request is coming from?
I've looked around at fasthttp.HostClient which fiber.Agent extends but I didn't see anything useful.
Thanks guys.

得分: 1
a := fiber.AcquireAgent()
req := a.Request()
req.Header.SetMethod(fiber.MethodGet)
req.SetRequestURI(fmt.Sprintf(formatUrl, args...))
if err := a.Parse(); err != nil {
h.Logger.Error("%v", err)
return fiber.StatusInternalServerError, nil, []error{err}
}
customDialer := fasthttp.TCPDialer{
Concurrency: 1000,
LocalAddr: &net.TCPAddr{
IP: h.IPPool[atomic.AddUint32(&h.IpIdx, 1)%uint32(len(h.IPPool))],
},
}
a.HostClient.Dial = func(addr string) (net.Conn, error) {
return customDialer.Dial(addr)
}
创建一个自定义的拨号器和拨号函数可以更改与HTTP请求关联的本地地址。
英文:
a := fiber.AcquireAgent()
req := a.Request()
req.Header.SetMethod(fiber.MethodGet)
req.SetRequestURI(fmt.Sprintf(formatUrl, args...))
if err := a.Parse(); err != nil {
h.Logger.Error("%v", err)
return fiber.StatusInternalServerError, nil, []error{err}
}
customDialer := fasthttp.TCPDialer{
Concurrency: 1000,
LocalAddr: &net.TCPAddr{
IP: h.IPPool[atomic.AddUint32(&h.IpIdx, 1)%uint32(len(h.IPPool))],
},
}
a.HostClient.Dial = func(addr string) (net.Conn, error) {
return customDialer.Dial(addr)
}
Creating a custom dialer and dial func allows you to change the local address associated with the http request.
