使用Google表格,我已将我的api_key和api_secret分别存储在用户信息的属性服务部分" api_key"和api_secret"。
我想从我的帐户中获取钱包信息。我写的代码如下:
function wallet() {
var api_key = PropertiesService.getScriptProperties().getProperty('api_key');
var api_secret = PropertiesService.getScriptProperties().getProperty('api_secret');
var response = UrlFetchApp.fetch("https://api.bitfinex.com/v2/auth/r/wallets", api_key, api_secret);
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("sheet");
var result = JSON.parse(response.getContentText());
var wallet_btc = result.BALANCE
}
当我在调试模式下运行时,错误消息是:
Cannot find method fetch(string,null,null). (line 13, file "Code")
这种做法是错误的,代码错了,还是两者兼而有之?
非常感谢。
答案 0 :(得分:1)
以下修改如何?
UrlFetchApp.fetch()
的参数为UrlFetchApp.fetch(url, params)
。 params
是一个对象。
Cannot find method fetch(string,null,null). (line 13, file "Code")
。api_key
,api_secret
,nonce
,body
和signature
创建请求正文。并且signature
由HMAC_SHA_384加密并转换为无符号十六进制的字符串。https://api.bitfinex.com/v2/auth/r/wallets
端点的样本如下。这来自API reference。https://api.bitfinex.com/v2/auth/r/wallets
request.post(
`${url}/auth/r/wallets`,
headers: { /* auth headers */ },
body: {},
json: true,
(error, response, body) => console.log(body)
)
当以上几点反映到您的脚本时,修改后的脚本如下所示。
function wallet() {
var api_key = PropertiesService.getScriptProperties().getProperty('api_key');
var api_secret = PropertiesService.getScriptProperties().getProperty('api_secret');
var apiPath = "v2/auth/r/wallets";
var nonce = Date.now().toString();
var body = {};
var rawBody = JSON.stringify(body);
var signature = "/api/" + apiPath + nonce + rawBody;
signature = Utilities.computeHmacSignature(Utilities.MacAlgorithm.HMAC_SHA_384, signature, api_secret)
.map(function(e) {
var v = (e < 0 ? e + 256 : e).toString(16);
return v.length == 1 ? "0" + v : v;
}).join("");
var url = "https://api.bitfinex.com/" + apiPath;
var options = {
method: 'POST',
contentType: "application/json",
headers: {
'bfx-nonce': nonce,
'bfx-apikey': api_key,
'bfx-signature': signature
},
payload: rawBody
};
var response = UrlFetchApp.fetch(url, options);
var result = JSON.parse(response.getContentText());
Logger.log(result)
// var wallet_btc = result.BALANCE // I couldn't confirm whether this key exists.
}
我无法确认这是否有效。如果这不起作用,你能告诉我情况吗?我想修改。
如果您希望0.0957596
的结果为[["exchange", "USD", 14.81076629, 0, null], ["exchange", "BTC", 0.0957596, 0, null], ["funding", "BTC", 4.13E-6, 0, null], ["funding", "ETH", 3.50186961, 0, null], ["exchange", "OMG", 5.9E-7, 0, null]];
,则可以使用以下脚本。
function wallet() {
var api_key = PropertiesService.getScriptProperties().getProperty('api_key');
var api_secret = PropertiesService.getScriptProperties().getProperty('api_secret');
var apiPath = "v2/auth/r/wallets";
var nonce = Date.now().toString();
var body = {};
var rawBody = JSON.stringify(body);
var signature = "/api/" + apiPath + nonce + rawBody;
signature = Utilities.computeHmacSignature(Utilities.MacAlgorithm.HMAC_SHA_384, signature, api_secret)
.map(function(e) {
var v = (e < 0 ? e + 256 : e).toString(16);
return v.length == 1 ? "0" + v : v;
}).join("");
var url = "https://api.bitfinex.com/" + apiPath;
var options = {
method: 'POST',
contentType: "application/json",
headers: {
'bfx-nonce': nonce,
'bfx-apikey': api_key,
'bfx-signature': signature
},
payload: rawBody
};
var response = UrlFetchApp.fetch(url, options);
var result = JSON.parse(response.getContentText());
// Logger.log(result)
// var wallet_btc = result.BALANCE // I couldn't confirm whether this key exists.
var balance = 0;
for (var i in result) {
if (result[i][0] == "exchange" && result[i][1] == "BTC") {
balance = result[i][2];
break;
}
}
Logger.log(balance)
}
WALLET_TYPE
,CURRENCY
和BALANCE
的索引始终为0
,1
和{{1分别在响应中的每个元素。
