JS调用接口数据，返回来的是json格式

项目返回值用json格式，还给链接，再有的是用户名还有密码，如何调用数据？

转换成JSONObject，再获取相应的值
比如:
String a = "{'id':111,'name':'男','age':12}";
JSONObject obj = JSONObject.fromObject(a);
String id = obj.getString("id");
如果是JsonArray格式的数据，则用如下代码
String s1 = "[{'werks':'3000','matnr':'122300100','pono':'4500393609','poitem':'00020','ztsl':'2000.0'},"
+"{'werks':'3000','matnr':'13190063B','pono':'4500346258','poitem':'00010','ztsl':'15200.0'},"
+"{'werks':'1300','matnr':'111300379','pono':'4500443908','poitem':'00010','ztsl':'5700.0'}]";
JSONArray array = JSONArray.fromObject(s1);
JSONArray res = new JSONArray();
for (int i = 0; i < array.size(); i++) {
JSONObject object = array.getJSONObject(i);
String werks = object.getString("werks");
String matnr = object.getString("matnr");
String pono = object.getString("pono");
String poitem = object.getString("poitem");
String ztsl = object.getString("ztsl");
System.out.println("werks:"+werks+",matnr:"+matnr+",pono:"+pono+",poitem:"+poitem+",ztsl:"+ztsl);
}
如果对你有帮助，记得采纳哦，哈哈。

都不知道你在问什么

后太获取前台json值
String bankdata = request.getParameter("bankdata"); //获取 bank json数据
