javascript - 如何使用 sailsjs-nodejs 连接/合并两个 json 对象

Question

您好，我是 Sailsjs-Nodejs 的新手。在我的 Controller 中，我有两个需要合并/连接的 JSON 对象，这样我就可以创建第三个对象来发送响应

res.send(obj1) 输出

[
  {
    total_fare: "376",
    arrival_to: "ABV"
  },
  {
    total_fare: "312",
    arrival_to: "ACC"
  },
  {
    total_fare: "432",
    arrival_to: "BFN"
  }
]

res.send(obj2)输出

[
  {
    url: "nigeria.php",
    country: "Nigeria",
    city_code: "ABV"
  },
  {
    url: "ghana.php",
    country: "Ghana",
    city_code: "ACC"
  },
  {
    url: "south-africa.php",
    country: "South Africa",
    city_code: "BFN"
  }
]

这是我的预期结果 res.send(obj3) 应该输出

[
  {
    url: "nigeria.php",
    country: "Nigeria",
    city_code: "ABV",
    total_fare: "376",
    arrival_to: "ABV"
  },
  {
    url: "ghana.php",
    country: "Ghana",
    city_code: "ACC",
    total_fare: "312",
    arrival_to: "ACC"
  },
  {
    url: "south-africa.php",
    country: "South Africa",
    city_code: "BFN",
    total_fare: "432",
    arrival_to: "BFN"
  }
]

Answer 1

您可以执行以下操作，而无需修改源数组；

var arr = [{total_fare: "376",arrival_to: "ABV"},
           {total_fare: "312",arrival_to: "ACC"},
           {total_fare: "432",arrival_to: "BFN"}],
    brr = [{url: "nigeria.php",country: "Nigeria",city_code: "ABV"},
           {url: "ghana.php",country: "Ghana",city_code: "ACC"},
           {url: "south-africa.php",country: "South Africa",city_code: "BFN"}],
 merged = arr.map((o,i) => Object.assign({},o,brr[i]));
 console.log(merged);
