我写了个WEBSERVICE,并发布在远程服务器上,里面的接口主要是用来取和写远程服务器上的数据库内容,现在有个情况就是,客户端都是内网的,无法连接WEBSERVICE服务,所以我打算在内网服务器上再发布个同样接口的WEBSERVICE,利用这个内望发布的服务函数去调用远端发布的服务函数,我不知道这样是否可行,因为我也是新手但测试后发现内望发布的WEBSERVCE在调用远端发布的服务的时候总是报错:vWSObj := CreateOleObject('MSSOAP.SoapClient');
vWSObj.mssoapinit('http://xx.xx.xx.x/DataSynch/Ds.dll/wsdl/IDataSynch');
try
try
vWSObj.HandShake;
except
Result := 1;
end;
finally
vWSObj := Unassigned;
end;
在创建CreateOleObject('MSSOAP.SoapClient');时总是报,错误类型的字符串,我已经引用了COMOBJ而且我单独在EXE里调用远端服务又都是OK的,随知道为什么?
