使用Go来实现网游的签到
本篇文章,实际应用中并没有多大意义。不适用于所有网友及网游。只是笔者寓教于乐的一种形式。
主要是学习和练习Go语言的以下知识点:
- 变量的创建和赋值
- 数组的创建、赋值和遍历
- map的创建、修改和遍历
- MD5加密
- 网络请求
- 打印

签到功能用的是网页实现。
地址:
[POST]:http://120.78.201.23:808/cShop/item_checkpt.asp
[POST]:http://120.78.201.23:808/cShop/gacha.asp
需要在Body中携带参数
id=test1314
key=e13efe12345656e3
world=1
其中:id是用户的账号名称,key是密码的16位小写MD5,world是服务器id。
id=test1314&key=e13efe12345656e3&world=1
简单实现
package main
import (
"bytes"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
sendRequest4()
}
func sendRequest4() {
// Request (4) (POST http://120.78.201.23:808/cShop/gacha.asp)
params := url.Values{}
params.Set("id", "这里替换成自己的账号")
params.Set("key", "这里替换成自己密码的小写16位MD5")
params.Set("world", "1")
body := bytes.NewBufferString(params.Encode())
// Create client
client := &http.Client{}
// Create request
req, err := http.NewRequest("POST", "http://120.78.201.23:808/cShop/gacha.asp", body)
// Headers
req.Header.Add("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
// Fetch Request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Failure : ", err)
}
// Read Response Body
respBody, _ := ioutil.ReadAll(resp.Body)
// Display Results
fmt.Println("response Status : ", resp.Status)
fmt.Println("response Headers : ", resp.Header)
fmt.Println("response Body : ", string(respBody))
}
变型封装
将网络调用,抽象封装。把账号名和密码作为传参传递进功能函数。
暂不考虑密码加密的问题,即已知加密后的密码。
package main
import (
"bytes"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
checkptUrl := "http://120.78.201.23:808/cShop/item_checkpt.asp"
id := "这里替换成自己的账号"
key := "这里替换成自己密码的小写16位MD5"
sendRequest(checkptUrl,id,key)
}
func sendRequest(_url string,_id string,_key string) {
params := url.Values{}
params.Set("id", _id)
params.Set("key", _key)
params.Set("world", "1")
body := bytes.NewBufferString(params.Encode())
// Create client
client := &http.Client{}
// Create request
req, err := http.NewRequest("POST", _url, body)
// Headers
req.Header.Add("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
// Fetch Request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Failure : ", err)
}
// Read Response Body
respBody, _ := ioutil.ReadAll(resp.Body)
// Display Results
fmt.Println("response Status : ", resp.Status)
fmt.Println("response Body : ", string(respBody))
}
实现MD5加密
实现32位小写的MD5
func md5(str string) string {
h := md5.New()
h.Write([]byte(str))
return hex.EncodeToString(h.Sum([]byte(nil)))
}
实现16位小写的MD5。就是把标准普通的MD5字符串从中截取了。
func md5_16(str string) string {
h := md5.New()
h.Write([]byte(str))
rs :=[]rune(hex.EncodeToString(h.Sum([]byte(nil))))
return string(rs[8:24])
}
进一步改写
通过用户名和密码(明文)进行功能的运行
package main
import (
"bytes"
"crypto/md5"
"encoding/hex"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
checkptUrl := "http://120.78.201.23:808/cShop/item_checkpt.asp"
id := "这里替换成自己的账号"
key := "这里替换成自己的密码"
sendRequest(checkptUrl, id, md5_16(key))
}
func md5_16(str string) string {
h := md5.New()
h.Write([]byte(str))
rs := []rune(hex.EncodeToString(h.Sum([]byte(nil))))
return string(rs[8:24])
}
func sendRequest(_url string, _id string, _key string) {
// Request (POST http://120.78.201.23:808/cShop/gacha.asp)
params := url.Values{}
params.Set("id", _id)
params.Set("key", _key)
params.Set("world", "1")
body := bytes.NewBufferString(params.Encode())
// Create client
client := &http.Client{}
// Create request
req, err := http.NewRequest("POST", _url, body)
// Headers
req.Header.Add("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
// Fetch Request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Failure : ", err)
}
// Read Response Body
respBody, _ := ioutil.ReadAll(resp.Body)
// Display Results
fmt.Println("response Status : ", resp.Status)
fmt.Println("response Body : ", string(respBody))
}
多账号
使用数组来实现多账号列表。
数组实现
这里暂时没有对密码数组和账号数组的长度是否一直做判定,默认为长度相同。
package main
import (
"bytes"
"crypto/md5"
"encoding/hex"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
ids := [...]string{"账号1", "账号2", "账号3"}
keys := [...]string{"账号1密码", "账号2密码", "账号3密码"}
checkptUrl := "http://120.78.201.23:808/cShop/item_checkpt.asp"
//gachaUrl := "http://120.78.201.23:808/cShop/gacha.asp"
for index := 0; index < len(ids); index++ {
sendRequest(checkptUrl, ids[index], md5_16(keys[index]))
}
}
func sendRequest(_url string, _id string, _key string) {
// Request (POST http://120.78.201.23:808/cShop/gacha.asp)
params := url.Values{}
params.Set("id", _id)
params.Set("key", _key)
params.Set("world", "1")
body := bytes.NewBufferString(params.Encode())
// Create client
client := &http.Client{}
// Create request
req, err := http.NewRequest("POST", _url, body)
// Headers
req.Header.Add("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
// Fetch Request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Failure : ", err)
}
// Read Response Body
respBody, _ := ioutil.ReadAll(resp.Body)
// Display Results
fmt.Println("response Status : ", resp.Status)
//fmt.Println("response Headers : ", resp.Header)
fmt.Println("response Body : ", string(respBody))
}
func md5_16(str string) string {
h := md5.New()
h.Write([]byte(str))
rs := []rune(hex.EncodeToString(h.Sum([]byte(nil))))
return string(rs[8:24])
}
账号密码相同
假如用户名和密码是相同的特殊情况。
package main
import (
"bytes"
"crypto/md5"
"encoding/hex"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
ids := [...]string{"账号1", "账号2", "账号3"}
checkptUrl := "http://120.78.201.23:808/cShop/item_checkpt.asp"
//gachaUrl := "http://120.78.201.23:808/cShop/gacha.asp"
for _,value := range ids {
sendRequest(checkptUrl,value,md5_16(value))
}
}
func sendRequest(_url string,_id string,_key string) {
// Request (POST http://120.78.201.23:808/cShop/gacha.asp)
params := url.Values{}
params.Set("id", _id)
params.Set("key", _key)
params.Set("world", "1")
body := bytes.NewBufferString(params.Encode())
// Create client
client := &http.Client{}
// Create request
req, err := http.NewRequest("POST", _url, body)
// Headers
req.Header.Add("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
// Fetch Request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Failure : ", err)
}
// Read Response Body
respBody, _ := ioutil.ReadAll(resp.Body)
// Display Results
fmt.Println("response Status : ", resp.Status)
//fmt.Println("response Headers : ", resp.Header)
fmt.Println("response Body : ", string(respBody))
}
func md5_16(str string) string {
h := md5.New()
h.Write([]byte(str))
rs :=[]rune(hex.EncodeToString(h.Sum([]byte(nil))))
return string(rs[8:24])
}
map实现
package main
import (
"bytes"
"crypto/md5"
"encoding/hex"
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
checkptUrl := "http://120.78.201.23:808/cShop/item_checkpt.asp"
//gachaUrl := "http://120.78.201.23:808/cShop/gacha.asp"
map_id := make(map[string]string)
map_id["账号1"] = md5_16("密码1")
map_id["账号2"] = md5_16("密码2")
map_id["账号3"] = md5_16("密码3")
for key,value := range ids {
sendRequest(checkptUrl,key,value)
}
}
func sendRequest(_url string,_id string,_key string) {
// Request (POST http://120.78.201.23:808/cShop/gacha.asp)
params := url.Values{}
params.Set("id", _id)
params.Set("key", _key)
params.Set("world", "1")
body := bytes.NewBufferString(params.Encode())
// Create client
client := &http.Client{}
// Create request
req, err := http.NewRequest("POST", _url, body)
// Headers
req.Header.Add("Content-Type", "application/x-www-form-urlencoded; charset=utf-8")
// Fetch Request
resp, err := client.Do(req)
if err != nil {
fmt.Println("Failure : ", err)
}
// Read Response Body
respBody, _ := ioutil.ReadAll(resp.Body)
// Display Results
fmt.Println("response Status : ", resp.Status)
//fmt.Println("response Headers : ", resp.Header)
fmt.Println("response Body : ", string(respBody))
}
func md5_16(str string) string {
h := md5.New()
h.Write([]byte(str))
rs :=[]rune(hex.EncodeToString(h.Sum([]byte(nil))))
return string(rs[8:24])
}
