最近看上了一个地图，在网上有电子版的，但是电子地图是由一小块一小块图片组成了，我想把他们下载到电脑上，图片太多，又不想一个地址一个地址地复制，怎么办？于是，写了个小程序：

#include <vector>

#include <urlmon.h>

#include <string>

#include <iostream>

using namespace std;

#pragma comment(lib, "urlmon.lib")

int main(int argc, char* argv[])

{

	int i, j;

	string url;

	string file;

	char tmp_url[1024];

	char tmp_file[100];

	wchar_t *buffer_url;

	wchar_t *buffer_file;

	size_t len;

	int nmlen;



	for (i = 0; i < 10; i++) {

		for (j = 0; j < 10; j++) {

			sprintf(tmp_url, "http://img.wikia.nocookie.net/intmap_tile_set_5360/4/%d/%d.png", i,j);

			sprintf(tmp_file, "%d_%d.png", i, j);

			url = tmp_url;

			file = tmp_file;



			len = url.length();

			nmlen = MultiByteToWideChar(CP_ACP, 0, url.c_str(), len + 1, NULL, 0);

			buffer_url = new wchar_t[nmlen];

			MultiByteToWideChar(CP_ACP, 0, url.c_str(), len + 1, buffer_url, nmlen);



			len = file.length();

			nmlen = MultiByteToWideChar(CP_ACP, 0, file.c_str(), len + 1, NULL, 0);

			buffer_file = new wchar_t[nmlen];

			MultiByteToWideChar(CP_ACP, 0, file.c_str(), len + 1, buffer_file, nmlen);



			URLDownloadToFile(NULL, buffer_url, buffer_file, 0, 0);

			delete[]buffer_url;

			delete[]buffer_file;

			cout << url << "  ->>>" << file << endl;

		}

	}





	system("pause");

	return 0;

}
