java如何在json中获得具有相同变量名的值

Question

我必须在这个json数组中获取值

{"certificates":[
{"alias":"CSTQUE","hsm":"HSM2","cf":"XXXXX","email":"xxx@xxx.it","cell":"+12345678"},
{"alias":"AXO","hsm":"HSM2","cf":"XXXXX","email":"xxxx@xxx.it","cell":"+12345678"}]}

如何在Java中获得所有同名变量？我可以迭代它们，还是可以执行getString（“别名”）并获取这两个值

Answer 1

你必须先迭代抛出它们，然后才能访问每个对象中的变量 像这样

JSONArray array = theNameOfYourJsonObject.getJSONArray("certificates");
for(int i = 0; i < array.lengh; i++){
JSONObject object = arrey.get(i);
//now you have an object of the array
String alias = object.getString("alias");
}
