请求正文方法 PATCH 覆盖给出错误"attributes missing"

Question

我正在尝试通过他们的API和Google应用程序脚本更新名为3Commas的服务上的交易机器人程序。我正在尝试根据某些条件不时更新它使用的对(BTC_ETH、BTC_MANA等)。目前，我不知道为什么在调用中没有读取有效载荷信息。

最初我尝试了一个查询字符串，但失败了。通过阅读，我发现请求主体最适合POST/PUT操作。所以我现在用一个请求体来尝试它。通过PATCH进行呼叫。根据我所读到的内容，您需要在GAS中使用POST方法和PATCH的标头覆盖。我已经在"botParams"中包含了所有强制参数。以下是3commas文档：3commas

谢谢你的帮助。

这次修改怎么样？

修改要点：

• 在脚本中，botParams用于查询参数和请求体
• 当使用botParams作为查询参数时，需要转换为查询参数
• 通过这个'method': 'POST',，请求变成POST方法

当以上几点反映到您的脚本中时，它变成如下。

修改的脚本：

在这个修改后的脚本中，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：

• 这个修改后的脚本假设editBots、botParams、key和secret是正确的值

我无法对此进行测试。所以，当这不起作用时，我道歉。届时，您能否提供响应值的详细信息？

编辑1:

在该修改中，JSON.stringify()仅用于作为对象的pairs和strategy_list。这样，其他值就不会被双引号括起来。

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：

虽然我不确定API的规范，但你能尝试一下这个修改吗？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。

为了测试这一点，请按如下方式修改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 ? "&" : "");
