又开始倒腾webservice了，习惯性使用bcb6来弄，遇到了些问题，在这里记录一下：
1）按照其它文章描述的那样，需要考虑处理中文，增加UTF8相应设置，这里需要提示下部分主机会需要认证，处理的位置在rio->HTTPWebNode->UserName处：

_di_SamServicePortType GetSamServicePortType(AnsiString username, AnsiString passwd, bool useWSDL, AnsiString addr)
{
    static const char* defWSDL= "C:\Documents and Settings\Administrator\My Documents\samapi.xml";
    static const char* defURL = "http://192.168.13.19:8080/sam/services/samapi";
    static const char* defSvc = "SamService";
    static const char* defPrt = "SamServicePort";
    if (addr=="")
        addr = useWSDL ? defWSDL : defURL;
    THTTPRIO* rio = new THTTPRIO(0);
    if (useWSDL) {
        rio->WSDLLocation = addr;
        rio->Service = defSvc;
        rio->Port = defPrt;
    } else {
        rio->URL = addr;
    }
    rio->HTTPWebNode->UseUTF8InHeader = true;
    if(!(username=="" && passwd==""))
    {
        rio->HTTPWebNode->UserName = username;
        rio->HTTPWebNode->Password = passwd;
    }
    rio->Converter->Options<<soUTF8InHeader; 
    _di_SamServicePortType service;
    rio->QueryInterface(service);
    if (!service)
        delete rio;
    return service;
}

2）设置RegTypes
大部分文章提到要设置RegisterInvokeOptions，修改为ioDocument，这样是不够的，应该如下：

static void RegTypes()
{
  /* SamServicePortType */
  InvRegistry()->RegisterInterface(__interfaceTypeinfo(SamServicePortType), L"http://api.spl.ruijie.com/", L"UTF-8");
  InvRegistry()->RegisterDefaultSOAPAction(__interfaceTypeinfo(SamServicePortType), L"");
  InvRegistry()->RegisterInvokeOptions(__interfaceTypeinfo(SamServicePortType), ioDocument|ioLiteral|ioHasNamespace);
}

如果不设置ioHasNamespace，在上传参数时可能会出现提示参数不可为空，“Unmarshalling Error”之类的错误。
