先上代码:

@At
	@Ok("re:jsp:jsp.admin.rader")
	public NutMap rader(String id){
		//存储时间段
		String[] dateTime=new String[10];
		//存储图像路径
		String[] images=new String[10];
		HttpRequest request = HttpRequest.get("http://products.weather.com.cn/product/radar/index/procode/JC_RADAR_"+id+"_JB");
		String htmlBody=request.body();
		//截取数据
		htmlBody = htmlBody.substring(htmlBody.indexOf("<select name=\"slide3\""), htmlBody.indexOf("</form>"));
		Document doc = Xmls.xml(Lang.ins(htmlBody));
		NodeList optionNode = doc.getElementsByTagName("option");
		NutMap map=new NutMap();
		for (int i = 0; i < 10; ++i) {
			//截取10个option节点
			Element element = ((Element) optionNode.item(optionNode.getLength()-10+i));
			images[i] = element.getAttribute("value").replaceFirst("/l/", "/m/");
			dateTime[i] = element.getTextContent().substring(11);
			map.addv("dateTime",dateTime[i]);
			map.addv("images",images[i]);
		}

		return map;

异常信息:

用的ViewZone的话, 返回值只能是String的

@Ok("re:jsp:jsp.admin.rader")

你要返回对象到页面的话, 加上ViewModel参数

你这个也是咋来的??

@Ok改成我写的值

搞定 谢谢前辈！ 我能问一下原理吗？

@Ok("re:XXXXXX") 方法的返回值必须是String,你写成NutMap就不能这样用咯
