我正在使用 javascript,我想将两个 JSON 文件加入到一个包含所有属性的 JSON 对象中。现在这两个 JSON 文件有单独的信息,但我需要将它们合并起来。
Station Information JSON - 下面的示例:
{
"last_updated":1493307962,
"ttl":10,
"data":{
"stations":[
{
"station_id":"219",
"name":"Central Square - East Boston",
"short_name":"A32036",
"lat":42.37454454514976,
"lon":-71.03837549686432,
"region_id":10,
"rental_methods":[
"KEY",
"CREDITCARD"
],
"capacity":19,
"eightd_has_key_dispenser":false
},
{
"station_id":"220",
"name":"Test 1",
"short_name":"Test 1",
"lat":0,
"lon":0,
"rental_methods":[
"KEY",
"CREDITCARD"
],
"capacity":0,
"eightd_has_key_dispenser":false
}
]
}
}
Station Status JSON - 下面的示例:
{
"last_updated":1493308075,
"ttl":10,
"data":{
"stations":[
{
"station_id":"219",
"num_bikes_available":7,
"num_bikes_disabled":1,
"num_docks_available":11,
"num_docks_disabled":0,
"is_installed":1,
"is_renting":1,
"is_returning":1,
"last_reported":1493283725,
"eightd_has_available_keys":false
},
{
"station_id":"220",
"num_bikes_available":0,
"num_bikes_disabled":0,
"num_docks_available":0,
"num_docks_disabled":0,
"is_installed":0,
"is_renting":0,
"is_returning":0,
"last_reported":0,
"eightd_has_available_keys":false
}
]
}
}
具体来说,我查看了这篇文章( How to join two json object in javascript, without using JQUERY ),但是这两个 JSON 文件的结构更复杂,所以我无法使其工作。
任何建议将不胜感激。
最佳答案
此代码的行为类似于第二个对象上的联接(但可以扩展以执行完整的外部联接)
它通过将字符串 _conflict
附加到键名称来处理冲突
我写这个是为了帮助您入门,但您必须对其进行自定义以支持您的确切结构
组合后的对象不再是列表,但具有与数组相同的索引。
var obj1 = {
"conflicting_key":1493307962,
"concurrent_key":10,
"data":{
"listOfEvents":[
{
"event_id":219,
"name":"Central Square - East Boston",
"rental_methods":[
"KEY",
"CREDITCARD"
],
"capacity":19
},
{
"event_id":220,
"name":"Test 1",
"lat":0,
"lon":0,
"rental_methods":[
"KEY",
"CREDITCARD"
],
"capacity":0,
"eightd_has_key_dispenser":false
}
]
}
};
var obj2 = {
"conflicting_key":1493308075,
"concurrent_key":10,
"data":{
"listOfEvents":[
{
"event_id":219,
"num_bikes_available":7,
"num_bikes_disabled":1,
"last_reported":1493283725,
"eightd_has_available_keys":false
},
{

"num_bikes_disabled":0,
"num_docks_available":0,
"is_returning":0,
"last_reported":0,
"eightd_has_available_keys":false
}
]
}
};
function combine(obj1, obj2) {
var combinedObject = Object.assign({}, obj1);
for(var key in obj2) {
if(typeof obj2[key] !== "object") {
if(obj1[key] !== obj2[key]) {
var keyName = key;
if(key in obj1) {
keyName = keyName + "_conflict";
}
combinedObject[keyName] = obj2[key];
}
} else {
combinedObject[key] = combine(obj1[key], obj2[key]);
}
}
return combinedObject;
}
console.log(combine(obj1, obj2));
