1.ajax发送get请求时，需要注意如下情况：
var uri="http://127.0.0.1:8071/springmvcdemo/bigdataapi/publishdata";
1）若URL不加“？”，则变成proxy+"http://127.0.0.1:8071/springmvcdemo/bigdataapi/publishdata"+"&udbPath=...&mapName=....."；即将uri当作一个参数
2）加上“？”，则将url看做一个完整的路径
也可以在拼接地址时直接加上参数，如url = proxy + "http://127.0.0.1:8010/style.set?layer=" + layerName + "&backColor=" + backColor + "&item=" + itemVal;
var proxy="/webframe/biz/httpproxy/httpproxy.jsp?url=";
var url=proxy+"http://127.0.0.1:8071/springmvcdemo/bigdataapi/publishdata?";
$.ajax({
url:url,
type:"GET",
data:{udbPath:udbPath,
mapName:mapName,
hdfsPath:hdfsPath
},
dataType:"text",
success:function(data){
//$(".stateInfo").html("");
//statecontainer="<span >发布完成，本次发布总共耗时60秒。</span>";
//$("#publishResultInfo").append(statecontainer);
},
error:function(x,e){
layer.alert("err");
}
})
