关于webservice的调用问题
在网上找到的例子 用delphi 基于webservice发送短信
新浪发送短信的Web Service地址是http://smsinter.sina.com.cn/ws/smswebservice0101.wsdl，该Web Service就只有一个方法，即string sendXml(carrier,userid,password,mobilenumber,content,msgtype)。各个参数全部为string类型，其含义基本如下（可能不正确）。
根据提供的例子 我点发送按钮的时候老是会出错不知道为什么，请求大侠指教 另一个是我写的很简单的主窗口文件
一个是用delphi WSDL Importer向导根据 新浪web service地址生成的文件

编译后点击按钮出现以下问题
[解决办法]
最好指定Addr给它 ，我以前调用都是指定webroot给它的Addr的，也就是指明服务来源.
[解决办法]
DELPHI7的WebService好像很难兼容最新的，改用DELPHI 2010
[解决办法]
我用的2010，做的Webservice客户端没问题
你提供的这个例子，我觉得有些问题，你能用 WSDL importer 自动生成吗？我这边是不行。
还有，调Webservice一定要注意编码格式的问题，什么UTF-8，GB2312啊，如果不注意，很搞人的。我觉得你的问题一个出在这里了。
另，你出的分真少……
[解决办法]
没有完全解决，但知道是Delphi在解析返回内容上出的问题了
我这边返回的内容如下：
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<HTML><HEAD>
<TITLE>500 Internal Server Error</TITLE>
</HEAD><BODY>
<H1>Internal Server Error</H1>
The server encountered an internal error or
misconfiguration and was unable to complete
your request.<P>
Please contact the server administrator,
webmaster@staff.sina.com.cn and inform them of the time the error occurred,
and anything you might have done that may have
caused the error.<P>
More information about this error may be available
in the server error log.<P>
<HR>
<ADDRESS>Apache/1.3.37 Server at smsinter.sina.com.cn Port 80</ADDRESS>
</BODY></HTML>
上面的内容不重要，因为我没有注册新浪无线的账号，返回错误很正常，但Delphi没有正确的抛出返回的错误，问题就在最上一行的<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
原因应该是Delphi默认的是禁用DTD的，所以如果找到启用DTD的方法，应该就可以解决了，暂时没有找到，下班了，明天再说吧
