微信3.1.0.41逆向-微信3.1.0.41HOOK接口(WeChatHelper3.1.0.41.dll)-VC++調用實例方法(win32)

WeChatHelper3.1.0.41.dll接口適用所有語言，今天我來講一下用VC++(win32)來做個實例調用。

第一步：添加rapidjson類庫

VC++用到的JSON庫爲：rapidjson，rapidjson頭文件經在項目目錄中了，我們把它包含到項目中：

第二步：創建HTTP類

VC++用wininet進行HTTP通信，

HttpHelper.h

#pragma once
#include <iostream>
#include <windows.h>
#include <wininet.h>

using namespace std;

//每次讀取的字節數
#define READ_BUFFER_SIZE        4096

enum HttpInterfaceError
{
	Hir_Success = 0,        //成功
	Hir_InitErr,            //初始化失敗
	Hir_ConnectErr,            //連接HTTP服務器失敗
	Hir_SendErr,            //發送請求失敗
	Hir_QueryErr,            //查詢HTTP請求頭失敗
	Hir_404,                //頁面不存在
	Hir_IllegalUrl,            //無效的URL
	Hir_CreateFileErr,        //創建文件失敗
	Hir_DownloadErr,        //下載失敗
	Hir_QueryIPErr,            //獲取域名對應的地址失敗
	Hir_SocketErr,            //套接字錯誤
	Hir_UserCancel,            //用戶取消下載
	Hir_BufferErr,            //文件太大，緩衝區不足
	Hir_HeaderErr,            //HTTP請求頭錯誤
	Hir_ParamErr,            //參數錯誤，空指針，空字符
	Hir_UnknowErr,
};

	enum HttpRequest
	{
		Hr_Get,
		Hr_Post
	};
	class HttpHelper
	{
	public:
		HttpHelper(void);
		~HttpHelper(void);

	public:
		//  通過HTTP請求：Get或Post方式獲取JSON信息 
		const std::string RequestData(const std::string& strUrl,
			HttpRequest type = Hr_Get,
			std::string lpHeader = "",
			std::string lpPostData = "");
	protected:
		// 關閉句柄
		void Release();

		// 釋放句柄
		void ReleaseHandle(HINTERNET& hInternet);

		// 解析URL地址
		void ParseURLWeb(std::string strUrl, std::string& strHostName, std::string& strPageName, WORD& sPort);

	private:

第三步：解析JSON

和其它語言一樣，我就用獲取即時聊天數據爲實例：

聊天記錄對象是根據聊天記錄數據和類型創建的，我們來看一下聊天記錄的JSON數據結構：

 

{
    "cmdid": 7,
    "maxid": 5,
    "count": 75,
    "status": "ok",
    "qq": "2376140244",
    "data": [
{
            "localId": 42,
            "MsgSvrID": "2062239765205091112",
            "StrTalker": "18618087204@chatroom",
            "StrContent": "<?xml version=\"1.0\"?>\n<msg>\n\t<img aeskey=\"611118464e36d48e86c891c79e25b07c\" encryver=\"1\" cdnthumbaeskey=\"611118464e36d48e86c891c79e25b07c\" cdnthumburl=\"3058020100044c304a0201000204be9026a302032f5d0302045938f0b702045fefffb90425617570696d675f383038376264343062646134646465335f31363039353634303839373537020401090a020201000405004c56fb00\" cdnthumblength=\"4043\" cdnthumbheight=\"140\" cdnthumbwidth=\"56\" cdnmidheight=\"0\" cdnmidwidth=\"0\" cdnhdheight=\"0\" cdnhdwidth=\"0\" cdnmidimgurl=\"3058020100044c304a0201000204be9026a302032f5d0302045938f0b702045fefffb90425617570696d675f383038376264343062646134646465335f31363039353634303839373537020401090a020201000405004c56fb00\" length=\"24332\" md5=\"692efd877bce4ad7dc41becca0d2278d\" hevc_mid_size=\"24332\" />\n</msg>\n",
            "CreateTime": 1609564091,
            "IsSender": 0,
            "type": 3,
            "SubType": 0,
            "CompressContent": "",
            "BytesExtra": {
                "wxid": "wxid_y7hw81zn588b12",
                "thumb": "keepmoving8\\FileStorage\\Image\\Thumb\\2021-01\\e03c67108d6c39c020c48696dbd36916_t.dat",
                "image": "keepmoving8\\FileStorage\\Image\\2021-01\\4953c7f182c4741eec97c9ab6bfe1eb4.dat",
                "video": ""
            }
        },
        {
            "localId": 43,
            "MsgSvrID": "3036343329427015238",
            "StrTalker": "2656683682@chatroom",
            "StrContent": "收滿不收彈頭40",
            "CreateTime": 1609564122,
            "IsSender": 0,
            "type": 1,
            "SubType": 0,
            "CompressContent": "",
            "BytesExtra": {
                "wxid": "wxid_87rw855vmv4h22",
                "thumb": "",
                "image": "",
                "video": ""
            }
        },
        {
            "localId": 44,
            "MsgSvrID": "6558585969683208319",
            "StrTalker": "JI282940039",
            "StrContent": "要的滴滴我",
            "CreateTime": 1609564128,
            "IsSender": 0,
            "type": 1,
            "SubType": 0,
            "CompressContent": "",
            "BytesExtra": {
                "wxid": "",
                "thumb": "",
                "image": "",
                "video": ""
            }
        }
    ]
}

上面記錄中有三種記錄：

1.羣圖片消息，羣發送的微信ID和圖片的地址已顯示在擴展數據中。

2.羣文本消息，羣發送的微信ID顯示在擴展數據中。

3.普通好友文本消息，擴展數據都是空。

根據JSON數據結構，我們在創建RecordObject對象

RecordObject.h

#pragma once
#include <list>
using namespace std;
struct RecordBytesExtra
{
	char wxid[0x40] = { 0 };//      羣消息時發送者微信ID"
	char thumb[0x200] = { 0 };   //     圖片類型時縮微圖路徑"
	char image[0x200] = { 0 };// 圖片或視頻類型時圖片路徑"
	char video[0x200] = { 0 };//視頻類型時MP4路徑
};

struct RecordData
{
	int localId = 0;//記錄ID
	char MsgSvrID[255] = { 0 };//消息ID
	char  StrTalker[0x40] = { 0 };//消息微信ID
	char  StrContent[0x4000] = { 0 };//內容
	int CreateTime = 0;//創建時間
	int IsSender = 0;//是否自己發送
	int type = 0;//消息類型
	int SubType = 0;//子類型
	char CompressContent[0x40] = { 0 }; //這裏爲轉賬金額信息，有+與-表示：收到與轉出   
	RecordBytesExtra BytesExtra;//擴展消息
};

class RecordObject
{
public:
	RecordObject();
	RecordObject(const char * jsonData);
	int cmdid = 0;
	int maxid = 0;//記錄索引
	int count = 0;//信息條數
	char qq[20] = { 0 };//本人QQ
	char status[20] = { 0 };//狀態
	list<RecordData> data;//消息主體數組
};

RecordObject.cpp

#include "RecordObject.h"
#include <stdio.h>
#include <string.h>
#include<fstream>
#include<iostream>
#include <windows.h>
#include <tchar.h> 
#include "rapidjson.h"
#include "document.h"
#include "stringbuffer.h"
#include "filereadstream.h"
#include "filewritestream.h"
#include "writer.h"
using namespace rapidjson;
RecordObject::RecordObject()
{
}

RecordObject::RecordObject(const char * jsonData)
{
	rapidjson::Document document;
	document.Parse(jsonData);
	if (document.HasParseError())
	{
		return;
	}
	rapidjson::Value::ConstMemberIterator iter = document.FindMember("cmdid");
	if (iter != document.MemberEnd()) {
		cmdid = iter->value.GetInt();
	}
	iter = document.FindMember("cmdid");
	if (iter != document.MemberEnd()) {
		cmdid = iter->value.GetInt();
	}
	iter = document.FindMember("maxid");
	if (iter != document.MemberEnd()) {
		maxid = iter->value.GetInt();
	}
	iter = document.FindMember("count");
	if (iter != document.MemberEnd()) {
		count = iter->value.GetInt();
	}
	iter = document.FindMember("qq");
	if (iter != document.MemberEnd()) {
		sprintf_s(qq, "%s", iter->value.GetString());
	}
	iter = document.FindMember("status");
	if (iter != document.MemberEnd()) {
		sprintf_s(status, "%s", iter->value.GetString());
	}
	
	const rapidjson::Value& dataValue = document["data"];
	if (dataValue.IsArray())
	{
		for (rapidjson::SizeType i = 0; i < dataValue.Size(); ++i)
		{
				const rapidjson::Value& obj = dataValue[i];
				RecordData recordData;
				recordData.localId = obj["localId"].GetInt();
				sprintf_s(recordData.MsgSvrID, "%s", obj["MsgSvrID"].GetString());
				sprintf_s(recordData.StrTalker, "%s", obj["StrTalker"].GetString());
				sprintf_s(recordData.StrContent, "%s", obj["StrContent"].GetString());
				recordData.CreateTime = obj["CreateTime"].GetInt();
				recordData.IsSender = obj["IsSender"].GetInt();
				recordData.type = obj["type"].GetInt();
				recordData.SubType = obj["SubType"].GetInt();
				sprintf_s(recordData.CompressContent, "%s", obj["CompressContent"].GetString());
				const rapidjson::Value& subObj = obj["BytesExtra"];
				if (subObj.IsObject())
				{
					sprintf_s(recordData.BytesExtra.wxid, "%s", subObj["wxid"].GetString());
					sprintf_s(recordData.BytesExtra.thumb, "%s", subObj["thumb"].GetString());
					sprintf_s(recordData.BytesExtra.image, "%s", subObj["image"].GetString());
					sprintf_s(recordData.BytesExtra.video, "%s", subObj["video"].GetString());

				}
				data.push_back(recordData);			
		}
	}
}

第四步：對數據編碼和解碼

因爲 VC++是用 Unicode字符集，而Json都是用Utf-8，所以要對它們進行相互轉碼

Common.h

#pragma once

#include <vector>
#include <iostream>
#include <iterator>
#include <regex>
#include <ctime>
#include <string.h>
#include <io.h>
#include <direct.h>
#include <shlobj.h>
#include <string>
#include <codecvt>
#include <locale>
#include <iostream>
using namespace std;
char* UnicodeToUtf8(wchar_t* unicode);
char* UnicodeToUtf8(const wchar_t* unicode);
wchar_t* UTF8ToUnicode(char* str);
wchar_t* UTF8ToUnicode(const char* str);
wchar_t* UTF8ToUnicode(string text);

Common.cpp

#include "common.h"
/*
//unicode תUtf8
*/
char* UnicodeToUtf8(const wchar_t* unicode)
{
	int len;
	len = WideCharToMultiByte(CP_UTF8, 0, unicode, -1, NULL, 0, NULL, NULL);
	char* szUtf8 = (char*)malloc(len + 1);
	if (szUtf8 != 0) {
		memset(szUtf8, 0, len + 1);
	}
	WideCharToMultiByte(CP_UTF8, 0, unicode, -1, szUtf8, len, NULL, NULL);
	return szUtf8;
}
char* UnicodeToUtf8(wchar_t* unicode)
{
	int len;
	len = WideCharToMultiByte(CP_UTF8, 0, unicode, -1, NULL, 0, NULL, NULL);
	char* szUtf8 = (char*)malloc(len + 1);
	if (szUtf8 != 0) {
		memset(szUtf8, 0, len + 1);
	}
	WideCharToMultiByte(CP_UTF8, 0, unicode, -1, szUtf8, len, NULL, NULL);
	return szUtf8;
}

/*
//Utf8תunicode
*/
wchar_t* UTF8ToUnicode(const char* str)
{
	int    textlen = 0;
	wchar_t* result;
	textlen = MultiByteToWideChar(CP_UTF8, 0, str, -1, NULL, 0);
	result = (wchar_t*)malloc((textlen + 1) * sizeof(wchar_t));
	if (result != 0)
	{
		memset(result, 0, (textlen + 1) * sizeof(wchar_t));
	}
	MultiByteToWideChar(CP_UTF8, 0, str, -1, (LPWSTR)result, textlen);
	return    result;
}
wchar_t* UTF8ToUnicode(char* str)
{
	int    textlen = 0;
	wchar_t* result;
	textlen = MultiByteToWideChar(CP_UTF8, 0, str, -1, NULL, 0);
	result = (wchar_t*)malloc((textlen + 1) * sizeof(wchar_t));
	if (result != 0)
	{
		memset(result, 0, (textlen + 1) * sizeof(wchar_t));
	}
	MultiByteToWideChar(CP_UTF8, 0, str, -1, (LPWSTR)result, textlen);
	return    result;
}
wchar_t* UTF8ToUnicode(string text)
{
	const	char * str = text.c_str();
	int    textlen = 0;
	wchar_t* result;
	textlen = MultiByteToWideChar(CP_UTF8, 0, str, -1, NULL, 0);
	result = (wchar_t*)malloc((textlen + 1) * sizeof(wchar_t));
	if (result != 0)
	{
		memset(result, 0, (textlen + 1) * sizeof(wchar_t));
	}
	MultiByteToWideChar(CP_UTF8, 0, str, -1, (LPWSTR)result, textlen);
	return    result;
}

第五步：在主程序中應用

在vc++中我們用SetTimer來定時刷新即時聊天記錄

// CWechatHelper.cpp : 定義應用程序的入口點。
//

#include "framework.h"
#include "CWechatHelper.h"
#include "resource.h"
#include "common.h"
#include "HttpHelper.h"
#include "RecordObject.h"
#define MAX_LOADSTRING 100
INT_PTR CALLBACK    DialogProc(HWND, UINT, WPARAM, LPARAM);
HWND hwndDlg;
int APIENTRY wWinMain(_In_ HINSTANCE hInstance,
                     _In_opt_ HINSTANCE hPrevInstance,
                     _In_ LPWSTR    lpCmdLine,
                     _In_ int       nCmdShow)
{
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(lpCmdLine);
	//加載窗口
	DialogBox(hInstance, MAKEINTRESOURCE(IDD_DIALOG1), NULL, DialogProc);
	MSG  msg = {};
	//   5.1獲取消息
	while (GetMessage(&msg, 0, 0, 0))
	{
		//   5.2翻譯消息
		TranslateMessage(&msg);
		//   5.3轉發到消息回調函數
		DispatchMessage(&msg);
	}
}
//追加文本
void AppendText(const TCHAR *newText)
{
	int outLength = GetWindowTextLength(GetDlgItem(hwndDlg, IDC_EDIT_RECORD));

	TCHAR * buf = new TCHAR[outLength+1];
	
	GetDlgItemText(hwndDlg, IDC_EDIT_RECORD, buf, outLength + 1);
	wstring text(buf);
	text.append(newText).append(L"\r\n");
	//_tcscat_s(buf, outLength + 1, newText);
	SetDlgItemText(hwndDlg, IDC_EDIT_RECORD, text.c_str());
}
//回調刷新即時聊天記錄
void CALLBACK TimerProc(HWND hWnd, UINT nMsg, UINT nTimerid, DWORD dwTime)
{
	HttpHelper* http = new HttpHelper();
	string data = http->RequestData("http://127.0.0.1/?cmdid=7");
	RecordObject *recordObj = new RecordObject(data.c_str());
	for (auto record : recordObj->data)
	{
		AppendText(UTF8ToUnicode(record.StrContent));
	}
	delete http;
	delete recordObj;
}
//窗口消息回調
INT_PTR CALLBACK DialogProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
    UNREFERENCED_PARAMETER(lParam);
	switch (message)
	{
	//窗口初始化
	case WM_INITDIALOG:
	{
		hwndDlg = hDlg;
		//定時器
		SetTimer(hDlg, 1, 3000, TimerProc);
		SendMessage(GetDlgItem(hDlg,IDC_COMBO_TYPE), CB_ADDSTRING, 0, (LPARAM)(L"GET"));
		SendMessage(GetDlgItem(hDlg, IDC_COMBO_TYPE), CB_ADDSTRING, 0, (LPARAM)(L"POST"));
		SendMessage(GetDlgItem(hDlg, IDC_COMBO_TYPE), CB_SETCURSEL, 0, 0);
		SetDlgItemText(hwndDlg, IDC_EDIT1, TEXT("http://127.0.0.1/"));
		break;
