在j2me中实施yahoo股票报价 - white @ fault“redirect”响应（301）

Question

我打算实施报价雅虎股票。运行时，程序无法连接到我输入的指定URL。

它显示了模拟器中的混乱，如white @ fault "redirect " response(301)

以下是我连接到网址的代码：

public String getQuote() throws IOException,NumberFormatException { 
String url ="http://quote.yahoo.com/d/quotes.csv?s=ibm&f=slc1wop"; 
HttpConnection c = null; 
c =(HttpConnection) Connector.open(url,Connector.READ_WRITE, true); 
c.setRequestMethod(HttpConnection.GET); 
InputStream is = c.openInputStream(); 
StringBuffer sb = new StringBuffer(); 
int ch; 
  while ((ch = is.read()) != -1) { 
    sb.append((char) ch); 
  } 
return (sb.toString()); 
}
