我有以下json。
for (var key in post) {
var one = post[key];
console.log(one);
break;
}
我使用volley获取json响应。像 {
"status": 1,
"value": {
"details": [
{
"shipment_no": "60178000059574",
"shipment_ref_no": "VAPL/EXP/19",

"empid": "60097000005728"
},

}
}
Following is my code to parse json.
for (int i = 0; i < numberOfItems; i++) {
JSONObject jsonObjects = details.getJSONObject(i);
String shipmentNo = jsonObjects.getString("shipment_no");
JSONObject empId = jsonObject.getJSONObject("point_of_contact");
JSONObject productId = jsonObject.getJSONObject("products");
Iterator<String> iterator = empId.keys();
Iterator<String> productIterator = productId.keys();
while (iterator.hasNext()){
String key = iterator.next();
Log.d(TAG,empId.optString(key));
}
while (productIterator.hasNext()){
String key = iterator.next();
Log.d(TAG,.optString(key));
}
}
这样的键和emp_id中的键是动态的。因此，我遍历json以获取键和值。但是，它会抛出一条错误消息products和no value exists for pointOfContact。为什么我会收到此错误？
