C语言 在程序中打开网页,模拟鼠标点击、键盘输入

一、简述

        记--使用C语言 打开指定网页,并模拟鼠标点击、键盘输入。实现半自动填写账号密码,并登录网站(当然现在的大部分网站都有验证码,或有检测"非人为"操作,以防止恶意注册、登录)。

四、源文件

main.c文件
 
 
#include <stdio.h>
 
#include <stdlib.h>
 
#include <Windows.h> //ShellExecuteA()
 
 
 
//打开某个网址:website (使用默认浏览器) 
 
void open_web(char
 
{
 
ShellExecuteA(0,"open", website,0,0,1);
 
}
 
 
 
 
 
//模拟鼠标点击 (x,y)是要点击的位置 
 
void click(int x, int
 
{
 
//将鼠标光标移动到 指定的位置 例子中屏幕分辨率1600x900 在鼠标坐标系统中,屏幕在水平和垂直方向上均匀分割成65535×65535个单元
 
mouse_event(MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_MOVE, x*65535/1600, y*65535/900, 0, 0);
 
 
 
Sleep(50);//稍微延时50ms 
 
mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);//鼠标左键按下 
 
mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);//鼠标左键抬起
 
}
 
 
 
//模拟键盘输入 keybd_event(要按下的字符,0,动作,0);动作为0是按下,动作为2是抬起 
 
void input()
 
{
 
char user[]="1234567890123";//账号 
 
char pwd[]="1234567890";//密码 
 
 
 
click(823,392); //点击"用户名输入框"的位置 
 
 
 
int

Sleep(30);
 
}
 
 
 
//tab键 对应的编号是0x09 让密码输入框 获取焦点

}
 
 
 
 
 
//将chrome.exe进程杀掉,在例子中尚未使用 
 
void close()
 
{
 
system("taskkill /f /im chrome.exe");
 
}
 
 
 
int main(int argc,char
 
{
 
open_web("https://www.baidu.com/");//打开某个网址 
 
Sleep(4000);//延时4秒,等待网页打开完毕,再进行其它操作。根据实际情况(浏览器打开速度,网速) 
 
click(1454, 126);//点击"登录"(1454,126) 
 
Sleep(150);
 
click(712,658);//点击"用户名登录"
 
Sleep(150);
 
input();//模拟鼠标动作,键盘输入 
 
return 0;
 
}

 

五、总结

      5.1 ShellExecute()函数 

ShellExecute()函数

功能

对指定的文件执行操作。(可以实现调用第三方程序)

头文件

Windows.h   

原型

HINSTANCE ShellExecuteA( HWND hwnd, LPCSTR lpOperation, LPCSTR lpFile, LPCSTR lpParameters, LPCSTR lpDirectory, INT nShowCmd );

参数

hwnd

父窗口的句柄。如果操作与窗口不关联,则此值可以为空

lpOperation

指定要执行的操作(谓词)

edit:启动编辑器并打开文档进行编辑。要打开的文档文件由lpFile指定

explore:浏览由参数lpFile指定的文件夹

find:搜索由参数lpDirectory指定的目录

open:打开lpFile参数指定的项。可以是文件或文件夹,或者是网页。

print:打印由lpFile指定的文件。

NULL:默认操作。如果没有,则使用“open”动词。如果“open”不可用,系统将使用注册表中列出的第一个谓词。

lpFile

操作对象(文件等。。。)

lpParameters

如果lpFile指定可执行文件,则此参数是指向以-结束的字符串的指针,该字符串指定要传递给应用程序的参数。此字符串的格式由要调用的谓词决定。如果lpFile指定文档文件,则lpParameters应为空。

lpDirectory

指定操作的默认(工作)目录。如果此值为NULL,则使用当前工作目录。

nShowCmd

指定打开应用程序时如何显示的标志。如果lpFile指定文档文件,则只需将标志传递给关联的应用程序。应该由应用程序来决定如何处理它。这些值是定义的。

SW_HIDE:隐藏

SW_MAXIMIZE :最大化

SW_MINIMIZE :最小化

。。。

返回值

如果函数成功,则返回大于32的值。如果函数失败,它将返回一个错误值

       打开指定网页:

ShellExecute(0, "open", "https://www.baidu.com/",0, 0, 1);//最后的参数是控制最大化、最小化,隐藏

 

       打开某个可执行文件:

 

 

#include <stdio.h>
 
#include <windows.h> //ShellExecute() 
 
 
 
int main(int argc, char
 
{
 
ShellExecute(0, "open", "C:\\Users\\newuser\\Desktop\\串口助手.exe",0, 0, 1);//最后的参数是控制最大化、最小化
 
printf("Hello World!\n");
 
return 0;
 
}
