Question

我正在尝试通过其API和Google Apps脚本更新名为3Commas的服务上的交易机器人。我正在尝试根据某些条件不时更新其使用的对（BTC_ETH，BTC_MANA等）。此刻，我迷失了为什么呼叫中未读取有效负载信息的原因。

最初，我尝试了一个失败的查询字符串。通过阅读，我发现请求正文最适合POST / PUT操作。因此，我现在正在尝试使用请求正文。呼叫是通过PATCH。据我所读，您需要使用POST方法和GAS中PATCH的标头替代。我已经将所有强制性参数包括在“ botParams”中。这是3个逗号的文档：3commas

感谢您的帮助。

  var totalParams = endPoint + payload; 
  Logger.log(totalParams)
  var signature = Utilities.computeHmacSha256Signature(totalParams, secret);

此修改如何？

修改点：

在脚本中，botParams用于查询参数和请求正文。
使用botParams作为查询参数时，需要转换为查询参数。
通过此'method': 'POST',，该请求成为POST方法。

当以上几点反映到您的脚本中时，它如下所示。

修改后的脚本：

在此修改后的脚本中，请求botParams作为查询参数。

var editBots = "/ver1/bots/250549/update";
var baseUrl = "https://3commas.io";
var endPoint = "/public/api"+editBots+"?";
var botParams = {
  "name": "cqstoshi",
  "pairs": ["BTC_MANA","BTC_TRX","BTC_WAN"],
  "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": 2,
  "active_safety_orders_count": 1,
  "safety_order_step_percentage": 2.5,
  "take_profit_type": "total",
  "strategy_list": [{"strategy":"cqs_telegram"}],
  "bot_id": 250549
};
var keys = Object.keys(botParams); // Added
var totalParams = keys.reduce(function(q, e, i) { // Added
  q += e + "=" + encodeURIComponent(JSON.stringify(botParams[e])) + (i != keys.length - 1 ? "&" : ""); // Modified
  return q;
}, endPoint);
Logger.log(totalParams)
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 = { // Modified
  'APIKEY': key,
  'Signature': signature,
};
var params = { // Modified
  'method': 'PATCH',
  'headers': headers,
  muteHttpExceptions: true
};
var data = UrlFetchApp.fetch(baseUrl + totalParams, params).getContentText(); // Modified
var json = JSON.parse(data);
Logger.log(json)

注意：

此修改后的脚本假定editBots，botParams，key和secret是正确的值。

我无法测试。因此，如果这样做不起作用，我深表歉意。那时，您可以提供响应值的详细信息吗？

编辑1：

在此修改中，JSON.stringify()仅用于作为对象的pairs和strategy_list。这样，其他值不会被双引号引起来。

发件人：

q += e + "=" + encodeURIComponent(JSON.stringify(botParams[e])) + (i != keys.length - 1 ? "&" : ""); // Modified

收件人：

q += e + "=" + (typeof botParams[e] == "object" ? encodeURIComponent(JSON.stringify(botParams[e])) : encodeURIComponent(botParams[e])) + (i != keys.length - 1 ? "&" : "");

编辑2：

尽管我不确定API的规格，您可以尝试这种修改吗？是pairs=BTC_MANA&pairs=BTC_TRX&pairs=BTC_WAN。对于botParams，请不要从"pairs": ["BTC_MANA","BTC_TRX","BTC_WAN"],进行修改。

要对此进行测试，请按如下所示修改q +=...的行。

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 ? "&" : "");

请求正文方法PATCH覆盖给出错误“属性缺失”
