gSoap生成的服務(wù)器端，用于C++的客戶端調(diào)用時(shí)一般不存在編碼問(wèn)題，只需要程序自動(dòng)生成的soapXXXProxy.cpp以及SoapXXXProxy.h文件即可。

網(wǎng)頁(yè)端要調(diào)用時(shí)，將會(huì)遇到很多問(wèn)題。

???? 由于gSoap生成的是.WSDL文件，在Web服務(wù)里面現(xiàn)在流行的是.asmx文件。這個(gè)時(shí)候就需要用到VS自帶的WSDL轉(zhuǎn)換工具wsdl.exe。

@echo off @set path=F:\2012-6\temp wsdl.exe /out:myProxyClass.cs forecast.wsdl pause

?　在網(wǎng)頁(yè)編程時(shí)候，將生成的myProxyClass添加進(jìn)去即可。由于C++，gSoap以及ASP.NET三者之間數(shù)據(jù)類型的不同，傳輸中文時(shí)候會(huì)出現(xiàn)亂碼或者缺失的現(xiàn)象，這個(gè)時(shí)候就必須保證三者是用同樣的編碼格式，推薦使用utf-8，因?yàn)槠渌牟欢！！?/p>

　　首先是C++服務(wù)器端，讀取后的數(shù)據(jù)在交給gSoap文檔之前，必須將中文轉(zhuǎn)換成utf-8格式。

char cGBKStr[] = "我是中國(guó)人!"; int nRetLen = GBKToUTF8((unsigned char *)cGBKStr,NULL,NULL); char * lpUTF8Str = NULL; lpUTF8Str = new char[nRetLen + 1]; nRetLen = GBKToUTF8((unsigned char *)cGBKStr,(unsigned char *)lpUTF8Str,nRetLen);

?

第二在gSoap中設(shè)定

　soap_set_mode(&s,SOAP_C_UTFSTRING);

????? s為forecastService s;

　　最后是gSoap傳送回來(lái)的數(shù)據(jù)，在交給C++處理前，轉(zhuǎn)換成gbk格式。

char * lpGBKStr = NULL;int nRetLen = UTF8ToGBK((unsigned char *)Request.text,NULL,NULL); //再轉(zhuǎn)回來(lái)lpGBKStr = new char[nRetLen + 1];nRetLen = UTF8ToGBK((unsigned char *)Request.text,(unsigned char *)lpGBKStr,nRetLen);

???? 兩個(gè)轉(zhuǎn)換函數(shù)可以參照以下示例

#include <stdio.h>
#include <windows.h>

//GBK編碼轉(zhuǎn)換到UTF8編碼
int GBKToUTF8(unsigned char * lpGBKStr,unsigned char * lpUTF8Str,int nUTF8StrLen)

wchar_t * lpUnicodeStr = NULL;
int nRetLen = 0;

if(!lpGBKStr) //如果GBK字符串為NULL則出錯(cuò)退出
return 0;

nRetLen = ::MultiByteToWideChar(CP_ACP,0,(char *)lpGBKStr,-1,NULL,NULL); //獲取轉(zhuǎn)換到Unicode編碼后所需要的字符空間長(zhǎng)度
lpUnicodeStr = new WCHAR[nRetLen + 1]; //為Unicode字符串空間
nRetLen = ::MultiByteToWideChar(CP_ACP,0,(char *)lpGBKStr,-1,lpUnicodeStr,nRetLen); //轉(zhuǎn)換到Unicode編碼
if(!nRetLen) //轉(zhuǎn)換失敗則出錯(cuò)退出
return 0;

nRetLen = ::WideCharToMultiByte(CP_UTF8,0,lpUnicodeStr,-1,NULL,0,NULL,NULL); //獲取轉(zhuǎn)換到UTF8編碼后所需要的字符空間長(zhǎng)度
