需要安裝的軟件
1、安裝ImageMagick安裝完成后,將其安裝路徑添加到環境變量path中
2、安裝Tesseract-OCR
#define MAX_NAME_LEN 4 //定義驗證碼字符串的長度,這里是4位
int flen; //定義一個整型變量保存獲得文件的大小
long filedes;
long filedess; //保存文件句柄
char file[256]="c:\\test1.jpg"; //保存文件路徑及文件名
char result[4];//定義用于從文件中讀取驗證碼的數組
web_set_max_html_param_len("2000000");
//設置頁面接收最大的字節數,該設置應大于下載文件的大小
//下載含有驗證碼的網頁元素,并將其保存到參數中
