抓封包 ….

抓一般封包沒問題 … 抓 https ….

yum 裝 epel 後可裝

yum install ngrep

裝 nginx 與設定反向代理

worker_processes 1;
error_log /var/log/nginx/error.log;
events {
    worker_connections 1024;
}
http {
        access_log  /var/log/nginx/access.log;
        resolver 8.8.8.8 ipv6=off;
    server {
        listen 5000;
        location ~* ^/bot {
        proxy_buffering off;
            proxy_pass https://api.telegram.org$request_uri;
        }
    }
}

這邊用 go 寫一段程式

package main
import (
    "net/http"
    "encoding/json"
    "fmt"
    "bytes"
)

func main() {
    request_url := "https://api.telegram.org/bot610418721:AAGBzrJ5dYipW0DB9799999YFB6RDwM8x7s/sendMessage"
    client := &http.Client{}

    values := make(map[string]interface{})
    values["chat_id"] = "-390234700"
    values["text"] = "This is a test"
    values["disable_notification"] =  true

    jsonStr, _ := json.Marshal(values)
    req, _ := http.NewRequest("POST", request_url, bytes.NewBuffer(jsonStr))
    req.Header.Set("content-type", "application/json")

    res, err := client.Do(req)
    if(err != nil){
        fmt.Println(err)
    } else {
        fmt.Println(res.Status)
    }
}

ngrep -d any port 5000
