前言
汇率API是一种关键工具,汇率API为开发人员和企业提供了实时的汇率数据,以便进行货币兑换和汇率报价。在今天的全球化经济中,汇率波动对国际贸易和金融交易至关重要。因此,了解并及时获取准确的汇率数据对于决策者来说至关重要,货币兑换依然如此。
在开发应用程序或网站时,集成汇率API是一项重要任务。通过使用汇率API,开发人员可以轻松地获取最新的汇率数据,并将其应用于货币兑换计算、汇率报价和其他相关功能。这种接口的灵活性使开发人员能够根据自己的需求进行逐笔报价、批量订阅以及获取历史日K线、周K和月K等汇率数据。
汇率API的接入方法相对简单,只需按照提供的文档和示例代码进行操作。首先,开发人员需要获取访问API的凭证或密钥,这通常需要向相关机构或服务提供商注册并获得授权。获得凭证后,可以通过API的请求接口发送HTTP请求,以获取所需的汇率数据。
汇率数据对于进行货币兑换操作至关重要。无论是个人旅行还是跨国企业,都需要及时准确的汇率数据来计算和预估货币兑换的成本。通过使用汇率API,用户可以实时查询最新的汇率数据,并根据当前市场情况进行货币兑换。
此外,汇率报价也是使用汇率API的常见功能之一。金融机构、外汇交易商和企业需要根据实时市场行情提供汇率报价。通过集成汇率API,这些机构可以实时获取最新的汇率数据,并根据自己的业务需求进行相应的报价操作。

二、逐笔报价查询
逐笔报价功能允许您获取最新的汇率数据,包括买入、卖出、最高、最低等详细信息。通过订阅相关频道,您可以实时获取汇率变动的信息。请看下面实例代码:
import time import requests import json # Extra headers test_headers = { 'Content-Type': 'application/json' } ''' # Special Note: # GitHub: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api # Token Application: https://alltick.co # Replace "testtoken" in the URL below with your own token # API addresses for forex, cryptocurrencies, and precious metals: # https://quote.tradeswitcher.com/quote-b-ws-api # Stock API address: # https://quote.tradeswitcher.com/quote-stock-b-ws-api Encode the following JSON and copy it to the "query" field of the HTTP query string {"trace": "python_http_test1", "data": {"code": "700.HK", "kline_type": 1, "kline_timestamp_end": 0, "query_kline_num": 2, "adjust_type": 0}} {"trace": "python_http_test2", "data": {"symbol_list": [{"code": "700.HK"}, {"code": "UNH.US"}]}} {"trace": "python_http_test3", "data": {"symbol_list": [{"code": "700.HK"}, {"code": "UNH.US"}]}} ''' test_url1 = 'https://quote.tradeswitcher.com/quote-stock-b-api/kline?token=testtoken&query=%7B%22trace%22%20%3A%20%22python_http_test1%22%2C%22data%22%20%3A%20%7B%22code%22%20%3A%20%22700.HK%22%2C%22kline_type%22%20%3A%201%2C%22kline_timestamp_end%22%20%3A%200%2C%22query_kline_num%22%20%3A%202%2C%22adjust_type%22%3A%200%7D%7D' test_url2 = 'https://quote.tradeswitcher.com/quote-stock-b-api/depth-tick?token=testtoken&query=%7B%22trace%22%20%3A%20%22python_http_test2%22%2C%22data%22%20%3A%20%7B%22symbol_list%22%3A%20%5B%7B%22code%22%3A%20%22700.HK%22%7D%2C%7B%22code%22%3A%20%22UNH.US%22%7D%5D%7D%7D' test_url3 = 'https://quote.tradeswitcher.com/quote-stock-b-api/trade-tick?token=testtoken&query=%7B%22trace%22%20%3A%20%22python_http_test3%22%2C%22data%22%20%3A%20%7B%22symbol_list%22%3A%20%5B%7B%22code%22%3A%20%22700.HK%22%7D%2C%7B%22code%22%3A%20%22UNH.US%22%7D%5D%7D%7D' resp1 = requests.get(url=test_url1, headers=test_headers) time.sleep(1) resp2 = requests.get(url=test_url2, headers=test_headers) time.sleep(1) resp3 = requests.get(url=test_url3, headers=test_headers) # Decoded text returned by the request text1 = resp1.text print(text1) text2 = resp2.text print(text2) text3 = resp3.text print(text3)
三、批量订阅
批量订阅功能允许您同时查询多个货币对的汇率数据,节省了频繁发送请求的时间和资源消耗。您可以根据需求订阅感兴趣的货币对,获取实时的批量数据。请看下面实例代码:
import json import websocket # pip install websocket-client ''' # Special Note: # GitHub: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api # Token Application: https://alltick.co # Replace "testtoken" in the URL below with your own token # API addresses for forex, cryptocurrencies, and precious metals: # wss://quote.tradeswitcher.com/quote-b-ws-api # Stock API address: # wss://quote.tradeswitcher.com/quote-stock-b-ws-api ''' class Feed(object): def __init__(self): self.url = 'wss://quote.tradeswitcher.com/quote-stock-b-ws-api?token=testtoken' # Enter your websocket URL here self.ws = None def on_open(self, ws): """ Callback object which is called at opening websocket. 1 argument: @ ws: the WebSocketApp object """ print('A new WebSocketApp is opened!') # Start subscribing (an example) sub_param = { "cmd_id": 22002, "seq_id": 123, "trace":"3baaa938-f92c-4a74-a228-fd49d5e2f8bc-1678419657806", "data":{ "symbol_list":[ { "code": "700.HK", "depth_level": 5, }, { "code": "UNH.US", "depth_level": 5, } ] } } # If you want to run for a long time, you need to modify the code to send heartbeats periodically to avoid disconnection, please refer to the API documentation for details sub_str = json.dumps(sub_param) ws.send(sub_str) print("depth quote are subscribed!") def on_data(self, ws, string, type, continue_flag): """ 4 arguments. The 1st argument is this class object. The 2nd argument is utf-8 string which we get from the server. The 3rd argument is data type. ABNF.OPCODE_TEXT or ABNF.OPCODE_BINARY will be came. The 4th argument is continue flag. If 0, the data continue """ def on_message(self, ws, message): """ Callback object which is called when received data. 2 arguments: @ ws: the WebSocketApp object @ message: utf-8 data received from the server """ # Parse the received message result = eval(message) print(result) def on_error(self, ws, error): """ Callback object which is called when got an error. 2 arguments: @ ws: the WebSocketApp object @ error: exception object """ print(error) def on_close(self, ws, close_status_code, close_msg): """ Callback object which is called when the connection is closed. 2 arguments: @ ws: the WebSocketApp object @ close_status_code @ close_msg """ print('The connection is closed!') def start(self): self.ws = websocket.WebSocketApp( self.url, on_open=self.on_open, on_message=self.on_message, on_data=self.on_data, on_error=self.on_error, on_close=self.on_close, ) self.ws.run_forever() if __name__ == "__main__": feed = Feed() feed.start()
四、历史K线查询
API还支持历史K线查询,包括日K线、周K线和月K线。您可以根据时间范围和货币对进行查询,获取特定时间段内的汇率走势图。请看以下代码:
import time import requests import json # Extra headers test_headers = { 'Content-Type': 'application/json' } ''' # Special Note: # GitHub: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api # Token Application: https://alltick.co # Replace "testtoken" in the URL below with your own token # API addresses for forex, cryptocurrencies, and precious metals: # https://quote.tradeswitcher.com/quote-b-ws-api # Stock API address: # https://quote.tradeswitcher.com/quote-stock-b-ws-api Encode the following JSON and copy it to the "query" field of the HTTP query string {"trace": "python_http_test1", "data": {"code": "700.HK", "kline_type": 1, "kline_timestamp_end": 0, "query_kline_num": 2, "adjust_type": 0}} {"trace": "python_http_test2", "data": {"symbol_list": [{"code": "700.HK"}, {"code": "UNH.US"}]}} {"trace": "python_http_test3", "data": {"symbol_list": [{"code": "700.HK"}, {"code": "UNH.US"}]}} ''' test_url1 = 'https://quote.tradeswitcher.com/quote-stock-b-api/kline?token=testtoken&query=%7B%22trace%22%20%3A%20%22python_http_test1%22%2C%22data%22%20%3A%20%7B%22code%22%20%3A%20%22700.HK%22%2C%22kline_type%22%20%3A%201%2C%22kline_timestamp_end%22%20%3A%200%2C%22query_kline_num%22%20%3A%202%2C%22adjust_type%22%3A%200%7D%7D' test_url2 = 'https://quote.tradeswitcher.com/quote-stock-b-api/depth-tick?token=testtoken&query=%7B%22trace%22%20%3A%20%22python_http_test2%22%2C%22data%22%20%3A%20%7B%22symbol_list%22%3A%20%5B%7B%22code%22%3A%20%22700.HK%22%7D%2C%7B%22code%22%3A%20%22UNH.US%22%7D%5D%7D%7D' test_url3 = 'https://quote.tradeswitcher.com/quote-stock-b-api/trade-tick?token=testtoken&query=%7B%22trace%22%20%3A%20%22python_http_test3%22%2C%22data%22%20%3A%20%7B%22symbol_list%22%3A%20%5B%7B%22code%22%3A%20%22700.HK%22%7D%2C%7B%22code%22%3A%20%22UNH.US%22%7D%5D%7D%7D' resp1 = requests.get(url=test_url1, headers=test_headers) time.sleep(1) resp2 = requests.get(url=test_url2, headers=test_headers) time.sleep(1) resp3 = requests.get(url=test_url3, headers=test_headers) # Decoded text returned by the request text1 = resp1.text print(text1) text2 = resp2.text print(text2) text3 = resp3.text print(text3)
