First, let’s understand a few APIs
_getcwd
Gets the current working directory.
char *_getcwd( char *buffer, int maxlen );
buffer
Storage location for the path .
maxlen
Maximum length of the path in characters: char for _getcwd and wchar_t for _wgetcwd.
Easy to know: buffer is the path
maxlen: Is the length
The function is to get the path of the current program
Next API
URLDownloadToFile function
Downloads bits from the Internet and saves them to a file.
char *_getcwd( char *buffer, int maxlen ); wchar_t *_wgetcwd( wchar_t *buffer, int maxlen );
The following is the code:
#include#include #include #pragma comment(lib,"URlmon") int main() { char buffer[MAX_PATH]; _getcwd(buffer, MAX_PATH); strcat_s(buffer, "//1.jpg"); HRESULT Result = URLDownloadToFileA(NULL, "http://112.22.245.11:443/down/de0243d60205717a2a74aea53c0c500c-46353/1.jpg?cts=yd-f-U13274580& ctp=111A23A228A125&ctt=1484747960&limit=1&spd=1300000&ctk=4ab73a4a76e47ad0b181d0f9fc47b6a1&chk=de0243d60205717a2a74aea53c0c500c-46353", buffer, 0, NULL); switch (Result) { case S_OK:printf("The download started successfully.\n");break; case E_OUTOFMEMORY: printf("The buffer length is invalid, or there is insufficient memory to complete the operation.\n"); break; } return 0; }
