Question

我想在下面的响应中获得第一个具有In [37]: np.multiply(vec1,vec2) Out[37]: array([ 32.4, -87.8, -0. , -52.2, -24.4])的项目。在这种情况下，预期响应应为"shipping":"ABC"

我不太擅长用Postman编写Javascript测试。

谢谢。

Answer 1

这将返回带有"shipping": "ABC"的第一项：

// convert response data to array of key-value pairs
const entries = Object.entries(response);

// reduce array to the first matching object
const reducer = (acc, [key, val]) => {
  return (acc === null && val.shipping === "ABC") ?
    (acc = { [key]: val }) : null;
};

// return the found object or null
const found = entries.reduce(reducer, null);
/*
  {
    '37': {
       shipping_id: 37,
       position: 0,
       status: 'D',
       shipping: 'ABC',
       delivery_time: '24h-72h'
    }
  }
*/

工作示例：

const res = {
  "37": {
    shipping_id: 37,
    position: 0,
    status: "D",
    shipping: "ABC",
    delivery_time: "24h-72h"
  },
  "36": {
    shipping_id: 36,
    position: 0,
    status: "D",
    shipping: "DEF",
    delivery_time: ""
  },
  "28": {
    shipping_id: 28,
    position: 0,
    status: "D",
    shipping: "GHI",
    delivery_time: ""
  }
};

const entries = Object.entries(res);

const reducer = (acc, [key, val]) => {
  return (acc === null && val.shipping === "ABC") ?
    (acc = { [key]: val }) : null;
};

const found = entries.reduce(reducer, null);
console.log(found);

Answer 2

我从另一篇文章中找到了解决方法：

var response = JSON.parse(responseBody);

const result = Object.keys(response).find(v => response[v].shipping === 'ABC');

//your object keys are equal to id, you can just return key
console.log(result);

// if your object keys can be different from id you can do this
console.log(response[result].shipping_id);
