如何遍历Java中的json对象

您没有数组-您拥有名称为“ 000”等的 属性 。数组如下所示：

"array": [ {    "foo": "bar1",    "baz": "qux1"  }, {    "foo": "bar2",    "baz": "qux2"  }]

请注意，

[ ... ]

您可以遍历

JSONObject

keys()

// Unfortunately keys() just returns a raw Iterator...Iterator keys = jsonObject.keys();while (keys.hasNext()) {    Object key = keys.next();    JSonObject value = jsonObject.getJSonObject((String) key);    String component = value.getString("component");    System.out.println(component);}

要么：

@SuppressWarnings("unchecked")Iterator<String> keys = (Iterator<String>) jsonObject.keys();while (keys.hasNext()) {    String key = keys.next();    JSonObject value = jsonObject.getJSonObject(key);    String component = value.getString("component");    System.out.println(component);}
