我打算实施报价雅虎股票。当它运行时,程序没有连接到我输入的指定 url。
它在模拟器中显示一团糟white @ fault "redirect " response(301)
这是我连接到 url 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());
}
