将查询字符串转换为请求正文响应错误

Question

我正在尝试将有效的查询字符串转换为请求正文，但我收到一个错误，提示我缺少一个属性。我从另一篇文章中获得了@Tanaike 的帮助，该文章提供了将参数分解为编码格式的编码 URI 函数。但是，当我的“pairs”参数中有 30-50 对时，URLFetch 会出现查询字符串长度限制错误。所以我尝试将其作为请求正文发送。

var botParams = {
"name": "TestBot",
"base_order_volume": 0.001,
"take_profit": 1.5,
"safety_order_volume": 0.001,
"martingale_volume_coefficient": 2,
"martingale_step_coefficient": 1,
"max_safety_orders": 1,
"active_safety_orders_count": 1,
"safety_order_step_percentage": 2.5,
"take_profit_type": "total",
"stop_loss_percentage": 0,
"cooldown": 0,
"pairs": [
  "BTC_ADA",
  "BTC_TRX"
],
"trailing_enabled":"true",
"trailing_deviation":0.5,
"strategy_list": [
  {
    "strategy":"cqs_telegram"
  }
]
  };    
  
  try {

//    var totalParams = keys.reduce(function(q, e, i) {
//      q += (e == "pairs" ? botParams[e].reduce(function(s, f, j) {
//        s += e + "[]=" + f + (j != botParams[e].length - 1 ? "&" : "");
//        return s;
//      },"") : e + "=" + (typeof botParams[e] == "object" ? 
//encodeURIComponent(JSON.stringify(botParams[e])) : 
//encodeURIComponent(botParams[e]))) + (i != keys.length - 1 ? "&" : "");
//      return q;
//    }, endPoint); //Thanks to Tanaike


//Call
//Base
var baseUrl = "https://3commas.io";        
//Total Endpoint
var endPoint = "/public/api/ver1/bots/274339/update?";


//Convert Bot Params + endPoint to Encoded URI
var keys = Object.keys(botParams);
var totalParams = keys.reduce(function(q, e, i) {
  q += e + "=" + (typeof botParams[e] == "object" ? encodeURIComponent(JSON.stringify(botParams[e])) : encodeURIComponent(botParams[e])) + (i != keys.length - 1 ? "&" : "");
  Logger.log(encodeURIComponent(botParams[e]))
  return q;
},endPoint);

Logger.log(totalParams)   

//Create Signature
var signature = Utilities.computeHmacSha256Signature(totalParams, secret);    
//Convert from byte
signature = signature.map(function(e) {return ("0" + (e < 0 ? e + 256 : e).toString(16)).slice(-2)}).join("");

var headers = {
  "APIKEY": key,
  "Signature": signature,
};
var params = {
  "method": "PATCH",
  "headers": headers,     
  "payload" : totalParams,
  //Show full exceptions      
   muteHttpExceptions: true
};  

var finalURL = baseUrl + "/public/api/ver1/bots/274339/update";

Logger.log(finalURL)
//https://3commas.io/public/api/ver1/bots/274339/update

// Call final URL with params
var data = UrlFetchApp.fetch(finalURL, params).getContentText();
var json = JSON.parse(data);
Logger.log(json)
  } catch (err) {Logger.log(err)}
}

我收到的当前错误是{error_attributes={name=[is missing]}, error_description=Invalid parameters, error=record_invalid} 所以由于某种原因它无法识别我的姓名属性。当我记录结果时，我看到名称是作为字符串传递的。

记录结果：/public/api/ver1/bots/274339/update?name=TestBot&base_order_volume=0.001&take_profit=1.5&safety_order_volume=0.001&martingale_volume_coefficient=2&martingale_step_coefficient=1&max_safety_orders=1&active_safety_orders_count=1&safety_order_step_percentage=2.5&take_profit_type=total&stop_loss_percentage=0&cooldown=0&pairs=%5B%22BTC_ADA%22%2C%22BTC_TRX%22%5D&trailing_enabled=true&trailing_deviation=0.5&strategy_list=%5B%7B%22strategy%22%3A%22cqs_telegram%22%7D%5D

只是寻找关于它可能是什么的建议。谢谢。

我认为在您的情况下，botParams 可能需要以表单形式发送，而查询参数需要从botParams 创建以创建签名。所以修改后的脚本如下。

修改脚本：

var key = 'apikey';
var secret = 'apisecret';
var editBots = "/ver1/bots/274339/update";
var baseUrl = "https://3commas.io";
var endPoint = "/public/api"+editBots;
var botParams = {
  "name": "TestBot",
  "base_order_volume": 0.001,
  "take_profit": 1.5,
  "safety_order_volume": 0.001,
  "martingale_volume_coefficient": 2,
  "martingale_step_coefficient": 1,
  "max_safety_orders": 1,
  "active_safety_orders_count": 1,
  "safety_order_step_percentage": 2.5,
  "take_profit_type": "total",
  "stop_loss_percentage": 0,
  "cooldown": 0,
  "pairs": ["BTC_ADA", "BTC_TRX"],
  "trailing_enabled": "true",
  "trailing_deviation": 0.5,
  "strategy_list": [{"strategy": "cqs_telegram"}]
};
var keys = Object.keys(botParams);
var totalParams = keys.reduce(function(q, e, i) {return q += (e == "pairs" ? botParams[e].reduce(function(s, f, j) {return s += e + "=" + f + (j != botParams[e].length - 1 ? "&" : "")},"") : e + "=" + (typeof botParams[e] == "object" ? encodeURIComponent(JSON.stringify(botParams[e])) : encodeURIComponent(botParams[e]))) + (i != keys.length - 1 ? "&" : "")}, endPoint + "?");
var signature = Utilities.computeHmacSha256Signature(totalParams, secret);
signature = signature.map(function(e) {return ("0" + (e < 0 ? e + 256 : e).toString(16)).slice(-2)}).join("");
var headers = {
  'APIKEY': key,
  'Signature': signature,
};
var params = {
  method: 'PATCH',
  headers: headers,
  payload: Object.keys(botParams).reduce(function(o, e) {
    o[e] = typeof botParams[e] == "object" ? JSON.stringify(botParams[e]) : e;
    return o;
  }, {}),
  muteHttpExceptions: true
};
var data = UrlFetchApp.fetch(baseUrl + endPoint, params).getContentText();
Logger.log(data)

注意：

• 我不确定 API 的规范。所以如果上面的脚本不起作用，你能向API的经理询问以下几点吗？
  1. 关于"pairs": ["BTC_ADA", "BTC_TRX"], 的botParams，在此脚本中，使用与创建查询参数相同的过程，如pairs=BTC_ADA&pairs=BTC_TRX。这是正确的吗？
  2. key 和 secret 是否需要包含在 botParams 中才能创建 signature？
  3. key 和 secret 是否需要包含在负载中？
  4. 是否需要同时满足 2 和 3 的要求？

编辑：

修改点：

从：

  payload: Object.keys(botParams).reduce(function(o, e) {
    o[e] = typeof botParams[e] == "object" ? JSON.stringify(botParams[e]) : e;
    return o;
  }, {}),

到：

  payload: Object.keys(botParams).reduce(function(o, e) {
    o[e] = typeof botParams[e] == "object" ? JSON.stringify(botParams[e]) : botParams[e];
    return o;
  }, {}),

Answer 2

我发现了这个问题。怀疑是编码问题。这就是最终的工作。

        var totalParams2 = keys.reduce(function(q, e, i) {
          q += (e == "pairs" ? botParams[e].reduce(function(s, f, j) {
            s += e + encodeURIComponent("[]")+"=" + f + (j != botParams[e].length - 1 ? "&" : "");            
            return s;
          },"") : e + "=" + (typeof botParams[e] == "object" ? encodeURIComponent(JSON.stringify(botParams[e])) : encodeURIComponent(botParams[e]))) + (i != keys.length - 1 ? "&" : "");
          return q;
        }, "");

添加 e + encodeURIComponent("[]")+ 特别是因为 API 的设置方式。我必须对我的对数组进行编码。
