Google表格：解析JSON结果

Question

前言：我是JS的新手，并且已经尝试使用谷歌搜索我的解决方案几个小时。

我正在使用Google表格（在脚本编辑器中）对公共端点进行API调用。这是我目前的代码：

function getMaterials() {
    var myUrl = "https://api.guildwars2.com/v2/account/materials?access_token=[my_access_token]";
    var jsonData = UrlFetchApp.fetch(myUrl);
    var jsonString = jsonData.getContentText();
    return jsonString;
}

以下是返回内容的片段：

[
  {
    "id": 12134,
    "category": 5,
    "count": 14
  },
  {
    "id": 12238,
    "category": 5,
    "count": 0
  },
  {
    "id": 12147,
    "category": 5,
    "count": 6
  },
  {
    "id": 12142,
    "category": 5,
    "count": 12
  },
  {
    "id": 12135,
    "category": 5,
    "count": 0
  },
  {
    "id": 12246,
    "category": 5,
    "count": 1
  }
]

以下是我正在与之交互的特定API的文档：

没有真正的方法来过滤掉我的电话，或者我非常乐意使用它。

我希望查询“id”值，但只返回同一查询中的“count”值。我已尝试过各种网站的多种方式，但无法到达任何地方。帮助

Answer 1

我最终找到了其他一些能够满足我需要的JS代码。

它允许我通过将数据格式化为列的函数来提供API。我可以将这些数据放在其他工作表中，然后将其输入我的主页。

Answer 2

我找不到该端点的API文档，但我想您可以将数据转换为使用id作为键的对象。根据您的使用情况，最好只查询API以获取特定密钥（即，如果您只需要少量数据），如果可能的话，这会减少接收的数据量和内存使用量。但是如果没有这个，那应该会有所帮助！

var data = getMaterials(); 

// Map each object by ID
function getMaterialIdMap(data){
  var materials = {}; 
  for(var i = 0; i < data.length; i++ ){
    var material = data[i]; 
    if(material.hasOwnProperty('id')){ // Ensure we only get objects with ids
      materials[material.id] = material;
    }
  } 
  return materials
}

// Map just the count to id
function getIdToCountMap(data){
  var materials = {}; 
  for(var i = 0; i < data.length; i++ ){
    var material = data[i]; 
    if(material.hasOwnProperty('id') && material.hasOwnProperty('count')){ // Ensure we only get objects with counts and ids
      materials[material.id] = material.count; 
    }
  } 
  return materials
}

// For the full object by id
var materialMap = getMaterialIdMap(data);

// For just the counts 
var materialCountMap = getIdToCountMap(data);

// For use in the sheet =countFromId(12134)   //14
function countFromId (id){
   return materialCountMap[id];
}

function getMaterials(){
  // Just a dummy data function for live snippet replace me with your version that performs the actual request and returns data as an array of objects.
   return [
  {
    "id": 12134,
    "category": 5,
    "count": 14
  },
  {
    "id": 12238,
    "category": 5,
    "count": 0
  },
  {
    "id": 12147,
    "category": 5,
    "count": 6
  },
  {
    "id": 12142,
    "category": 5,
    "count": 12
  },
  {
    "id": 12135,
    "category": 5,
    "count": 0
  },
  {
    "id": 12246,
    "category": 5,
    "count": 1
  }
]

}var data = getMaterials(); 

// Map each object by ID
function getMaterialIdMap(data){
  var materials = {}; 
  for(var i = 0; i < data.length; i++ ){
    var material = data[i]; 
    if(material.hasOwnProperty('id')){ // Ensure we only get objects with ids
      materials[material.id] = material;
    }
  } 
  return materials
}

// Map just the count to id
function getIdToCountMap(data){
  var materials = {}; 
  for(var i = 0; i < data.length; i++ ){
    var material = data[i]; 
    if(material.hasOwnProperty('id') && material.hasOwnProperty('count')){ // Ensure we only get objects with counts and ids
      materials[material.id] = material.count; 
    }
  } 
  return materials
}


var materialMap = getMaterialIdMap(data);


// For just the counts 
var materialCountMap = getIdToCountMap(data);

// For the full object by id
function countFromId (id){
   return materialCountMap[id];
}

function getMaterials(){
  // Just a dummy data function for live snippet
   return [
  {
    "id": 12134,
    "category": 5,
    "count": 14
  },
  {
    "id": 12238,
    "category": 5,
    "count": 0
  },
  {
    "id": 12147,
    "category": 5,
    "count": 6
  },
  {
    "id": 12142,
    "category": 5,
    "count": 12
  },
  {
    "id": 12135,
    "category": 5,
    "count": 0
  },
  {
    "id": 12246,
    "category": 5,
    "count": 1
  }
]
