目前不需要注册开发者，只需要申请apikey apikey申请流程： 1.先注册账户 2.在设置页面，绑定GA 3.在设置页面，申请api，两个字段都必须填写，IP地址目前限制 limit：限价 market：市价

api文档： https://developer.fcoin.com/zh.html#32c808cbe5

交易手续费： https://support.fcoin.com/hc/zh-cn/articles/360003715514-%E4%BA%A4%E6%98%93%E6%89%8B%E7%BB%AD%E8%B4%B9%E5%8F%8A%E8%AE%A2%E5%8D%95%E8%A7%84%E5%88%99%E8%AF%B4%E6%98%8E

以下3个参数，需要放在headers中 FC-ACCESS-KEY FC-ACCESS-SIGNATURE FC-ACCESS-TIMESTAMP

websocket： def get_market_price(symbol): ws = create_connection("wss://ws.fcoin.com/api/v2/ws") ws.recv() s = "ticker.{}".format(symbol['name']) req = { 'cmd':'req', 'args':[s], 'id':'1' } ws.send(json.dumps(req)) r = json.loads(ws.recv()) ws.close() return r['data']['ticker'][0]

深度订阅，实际发送的内容是：{"cmd":"sub","args":["depth.L100.btcusdt"],"id":"1"}

获取订单列表中： 至少传symbol和state

git地址： https://github.com/FCoinCommunity

Post请求时一定要加json头： 'content-type': 'application/json;charset=UTF-8' 请求的body要传json格式

可以查询以提交和部分成交的数据： submitted, partial_filled, partial_canceled, filled, canceled 这些状态，可以同时传，中间用逗号隔开

Post签名前的字符串： POSThttps://api.fcoin.com/v2/orders1528532934527amount=1000&price=0.192011&side=buy&symbol=ftusdt&type=limit Get签名前的字符串： GEThttps://api.fcoin.com/v2/orders?limit=20&states=submitted,partial_filled&symbol=ethusdt1528532959168

获取订单接口中before和after表示时间戳，只能有1个时间戳，limit最大支持100

public是要传给服务器的，secret是用来签名的

1002 system busy 是因为下单太快了

获取行情深度接口中，只有L20，L150，full

python版本的签名代码： def sort_payload(self, payload): keys = sorted(payload.keys()) result = '' for i in range(len(keys)): if i != 0: result += '&' + keys[i] + "=" + str(payload[keys[i]]) else: result += keys[i] + "=" + str(payload[keys[i]]) return result

# 对请求数据进行加密编码
def encrypt_data(self, HTTP_METHOD, HTTP_REQUEST_URI, TIMESTAMP, POST_BODY, secret):
    payload_result = ''
    if POST_BODY != '':
        payload_result = self.sort_payload(POST_BODY)
    data = HTTP_METHOD + HTTP_REQUEST_URI + TIMESTAMP + payload_result
    print(data)
    data_base64 = base64.b64encode(bytes(data, encoding='utf8'))
    # print(data_base64)
    data_base64_sha1 = hmac.new(bytes(secret, encoding='utf8'), data_base64, hashlib.sha1).digest()
    data_base64_sha1_base64 = base64.b64encode(data_base64_sha1)
    # print(data_base64_sha1_base64)
    return str(data_base64_sha1_base64, encoding='utf-8')

def create_headers(self, HTTP_METHOD, HTTP_REQUEST_URI, TIMESTAMP, POST_BODY, public_key, secret_key):
    signature = self.encrypt_data(HTTP_METHOD, HTTP_REQUEST_URI, str(TIMESTAMP), POST_BODY, secret_key)
    self.headers['FC-ACCESS-KEY'] = public_key
    self.headers['FC-ACCESS-TIMESTAMP'] = str(TIMESTAMP)
    self.headers['FC-ACCESS-SIGNATURE'] = signature

Php版本的签名代码： // 获取毫秒时间戳 function get_millisecond() { list($t1, $t2) = explode(' ', microtime()); return (float)sprintf('%.0f', (floatval($t1) + floatval($t2)) * 1000); } //hmac_sha1算法 function getSignature($str, $key) { $signature = ""; if (function_exists('hash_hmac')) { $signature = base64_encode(hash_hmac("sha1", $str, $key, true)); } else { $blocksize = 64; $hashfunc = 'sha1'; if (strlen($key) > $blocksize) { $key = pack('H*', $hashfunc($key)); } $key = str_pad($key, $blocksize, chr(0x00)); $ipad = str_repeat(chr(0x36), $blocksize); $opad = str_repeat(chr(0x5c), $blocksize); $hmac = pack( 'H*', $hashfunc( ($key ^ $opad) . pack( 'H*', $hashfunc( ($key ^ $ipad) . $str ) ) ) ); $signature = base64_encode($hmac); } return $signature; } // 组合参数 function bind_param($param) { if($param){ $u = []; $sort_rank = []; foreach($param as $k=>$v) { $u[] = $k."=".urlencode($v); $sort_rank[] = ord($k); } asort($u); return implode('&', $u); }else{ return ''; }

}

    $this->access_timestamp = $this->get_millisecond();
    $sign_param_1 = $this->req_method.$this->sign_url.$this->api_method.$this->access_timestamp.$this->bind_param($param);
