win32获取浏览器当前Tab的URL

代码都是win10上测试的

 

1. 获取IE的URL，Enum IE窗口的子句柄，找到className为Edit的句柄，然后用SendMessage WM_GETTEXT消息来获取：

上代码：

 1 #include <iostream>
 2 #include <string>
 3 #include <windows.h>
 4 
 5 
 6 BOOL CALLBACK BrowserIEChildEnumProc(HWND hwndChild, LPARAM lParam)
 7 {
 8     char className[256] = { 0 };
 9     GetClassName(hwndChild, className, 256);
10     char url[4028] = { 0 };
11 
12     std::string class_name(className);
13     if (class_name.compare("Edit") == 0)
14     {
15     
16         SendMessage(hwndChild, WM_GETTEXT, sizeof(url), (LPARAM)url); // 必须用SendMessage, 不然用GetWindowText会得不到，因为是远程进程
17         std::cout << "IE Level Edit class : URL" << url << std::endl;
18     }
19     else if (class_name.compare("ComboBoxEx32") == 0)
20     {
21         SendMessage(hwndChild, WM_GETTEXT, sizeof(url), (LPARAM)url);
22         std::cout << "ComboBoxEx32 class : URL" << url << std::endl;
23 
24     }
25     else if (class_name.compare("TabWindowClass") == 0)
26     {
27         SendMessage(hwndChild, WM_GETTEXT, sizeof(url), (LPARAM)url);
28         std::cout << "TabWindowClass class : URL" << url << std::endl;
29     }
30     else
31     {
32 
33     }
34     
35     
36     return TRUE;
37 }
38 
39 
40 BOOL CALLBACK BrowserEnumProc(HWND hwndChild, LPARAM lParam)
41 {
42     char className[256] = { 0 };
43     
44     GetClassName(hwndChild, className, 256);
45 
46     std::string class_name(className);
47     //std::cout << "Window Class is:" << class_name << std::endl;
48     if (class_name.compare("IEFrame") == 0)
49     {
50         EnumChildWindows(hwndChild, BrowserIEChildEnumProc, NULL);
51     }
52     else if (class_name.compare("Edit") == 0)
53     {
54         char url[4028] = { 0 };
55         SendMessage(hwndChild, WM_GETTEXT, sizeof(url), (LPARAM)url);
56         std::cout << "Top Level Edit class : URL" << url << std::endl;
57     }
58     //else if ()
59     //{
60 
61     //}
62     
63 
64     return TRUE;
65 }
66 
67 
68 int main()
69 {
70     EnumChildWindows(NULL, BrowserEnumProc, NULL);
71 
72     
73     int d;
74     std::cin >> d;
75     return 0;
76 }

 

通过windows的动态数据交换（DDE）技术来获取FireFox浏览器的URL（不支持Opera 和Chrome）：

 1 #include <iostream>
 2 #include <string>
 3 #include <windows.h>
 4 
 5 #include <ddeml.h>
 6 
 7 
 8 
 9 
10 HDDEDATA CALLBACK
11 DdeCallback(UINT uType, UINT uFmt, HCONV hconv,
12 HSZ hsz1, HSZ hsz2, HDDEDATA hdata,
13 DWORD dwData1, DWORD dwData2)
14 {
15     return ((HDDEDATA)NULL);
16 }
17 
18 
19 //请求数据
20 void DDERequest(DWORD idInst, HCONV hConv, char* szItem, char* sDesc)
21 {
22     HSZ hszItem = DdeCreateStringHandle(idInst, szItem, 0);
23 
24     //给szItem和sDesc赋值
25     HDDEDATA hData = DdeClientTransaction(NULL, 0, hConv, hszItem, CF_TEXT,
26         XTYP_REQUEST, 5000, NULL); //5秒超时
27 
28     if (hData == NULL)
29     {
30         //请求数据失败
31         printf("Request failed: %s\n", szItem);
32     }
33     else
34     {
35         //成功获取到数据
36         char szResult[1028];
37         DdeGetData(hData, (unsigned char *)szResult, 1028, 0);
38 
39         printf("Request Success: %s\n", szResult);
40     }
41 }
42 
43 static void fetchFireFoxURL(){
44 
45     DWORD idDde = 0;
46     HCONV HConversation;
47     HSZ   Server = NULL;
48     HSZ   Topic = NULL;
49 
50     DdeInitialize(&idDde, (PFNCALLBACK)DdeCallback, APPCMD_CLIENTONLY, 0);
51 
52     Server = DdeCreateStringHandle(idDde, "FireFox", CP_WINANSI);
53     Topic = DdeCreateStringHandle(idDde, "WWW_GetWindowInfo", CP_WINANSI);
54     
55 
56     HConversation = DdeConnect(idDde, Server, Topic, NULL);
57 
58     
59     if (HConversation == 0)
60     {
61         DdeUninitialize(idDde);
62     }
63     
64     char recvData[2048] = { 0 };
65     //请求数据
66     DDERequest(idDde, HConversation, "\\Doc", recvData);
67 
68     //断开连接,释放资源
69     DdeDisconnect(HConversation);
70     DdeUninitialize(idDde);
71 
72 
73 
74 }
75 
76 int main()
77 {
78     
79 
80     fetchFireFoxURL();
81     
82     int d;
83     std::cin >> d;
84     return 0;
