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)。
例子打包：链接: https://pan.baidu.com/s/1eStV0lAcmr8kmEA0n3LRcg 提取码: 7kvj
二、效果 (程序填写账号密码，实现半自动登录)
三、工程结构
四、源文件
main.c文件
五、总结
5.1 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：
5.2 mouse_event()函数

| dwData | 滚轮滚动值 | ||
| dwExtraInfo | 与鼠标事件关联的附加值。调用GetMessageExtraInfo()以获取此额外信息 | ||
| 返回值 | 无返回值 | ||
| 备注 |
详见：https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-mouse_event
|
||
将鼠标移动到指定位置（x,y）
按下鼠标左键，然后抬起
5.3 keybd_event()函数
| 功能 | 合成击键。（模拟键盘输入） | ||
| 头文件 | Windows.h | ||
| 原型 | void keybd_event( BYTE bVk, BYTE bScan, DWORD dwFlags, ULONG_PTR dwExtraInfo ); | ||
| 参数 | bVk | 虚拟按键代码编号 | |
| bScan | 按键的的硬件扫描代码 | ||
| dwFlags |
控制功能操作的各个方面 KEYEVENTF_EXTENDEDKEY：如果指定，扫描代码前面有一个前缀字节，其值为0xE0 KEYEVENTF_KEYUP：如果指定，则抬起按键。 |
