1，放入FMZ调试工具，可以直接运行 2，获取币安usdt合约全币种名称及个数
function unique (str) {
var arr = str.split(',');
return Array.from(new Set(arr)).join(',')
}
function main() {
var exchange_info = JSON.parse(HttpQuery('https://fapi.binance.com/fapi/v1/exchangeInfo'));
var str = '';
exchange_info.symbols.forEach(function(exitem, index) {
if (exitem.symbol.indexOf('USDT') == -1) {return}
if (exitem.symbol.indexOf('BTCST') !== -1) {return}
if (exitem.symbol.indexOf('BTCDOM') !== -1) {return}
var content = ',';
if (index == exchange_info.symbols.length - 1) {
content = '';
}
str += exitem.baseAsset + content;
});
Log('全合约币种数量：', unique(str).split(',').length)
Log('全合约币种名称：',unique(str))
// return leverageBracket;
let leverageBracket = exchange.IO("api", "GET", "/fapi/v1/leverageBracket", "timestamp=" + new Date().getTime())
let newList = leverageBracket.map((item) => {
return {
symbol: item.symbol,
leverage: item.brackets[0].initialLeverage
}
})
let selectLeverage = 25;
newList = newList.filter((item) => {
return item.leverage >= selectLeverage;
})
Log('筛选币数量：' , newList.length);
let str2 = ''
newList.forEach(function(exitem, index) {
if (exitem.symbol.indexOf('USDT') == -1) {return}
if (exitem.symbol.indexOf('BTCST') !== -1) {return}
if (exitem.symbol.indexOf('BTCDOM') !== -1) {return}
var content = ',';
if (index == newList.length - 1) {
content = '';
}
str2 += exitem.baseAsset + content;
});
Log('筛选币名称：', str);
}
god 可以直接用 _.uniq([1, 2, 1, 4, 1, 3]); => [1, 2, 4, 3]
