[转载]python 自动卖出京东黄金 上个月看到虎友买卖京东积存金的，我也随手买了点。金价一直在 385 上下波动，我在 381 元时买入了两次，然后 388 左右卖出（并不推荐这样做，投机短线交易不可取），都小赚了一点点。老是看金价或者关注自动推送（是的，我还简单弄了个钉钉机器人监控价格哈哈）的话还是有点累，就想着拿 python 写个自动交易卖出的。看了请求加密一堆参数也懒得分析了，selenium 开干。大致如下，自行改造吧。简单写写，写的比较乱。只做了卖出，买入还是谨慎些，没考虑做。需要 Python3 环境，需要修改的地方就是那些 xxxxxxxxxxxxxxx。建议单步调试代码，看一下大致逻辑再使用。或者仅供参考，自己重新实现。20210201 11:00 成功自动卖出import json import sys import traceback from selenium import webdriver import time, requests def getLatestPrice(): url = 'https://api.jdjygold.com/gw/generic/hj/h5/m/latestPrice?reqData=%7B%7D' response = requests.get(url=url) print(response) print(response.headers) jsonRes = json.loads(response.content) price = float(jsonRes['resultData']['datas']['price']) print(time.strftime("%Y-%m-%d %H:%M:%S ", time.localtime()), '最新价', price) return price def openJdjyGold(): webdriverPath = "C:\Program Files\Google\Chrome\Application\chromedriver.exe" # webdriver路径 activityUrl = "https://m.jdjygold.com/finance-gold/newgold/index" sellGoldUrl = "https://m.jdjygold.com/finance-gold/newgold/sellGold/" # 如果直接去卖金的地方，可能来不及注入cookie browser = webdriver.Chrome(executable_path=webdriverPath) browser.set_window_size('400', '700') browser.get(activityUrl) browser.delete_all_cookies() # 读取cookie写入。第一次使用时注释掉这段，手动登陆一次后用下面的更新存储。自行改造啦。 with open('cookies.json', 'r', encoding='utf-8') as f: listCookies = json.loads(f.read()) for cookie in listCookies: browser.add_cookie({ 'domain': cookie['domain'], 'name': cookie['name'], 'value': cookie['value'], 'path': '/', 'expires': None }) # 更新一下文件存储的cookie cookies = browser.get_cookies() jsonCookies = json.dumps(cookies) with open('cookies.json', 'w') as f: f.write(jsonCookies) browser.get(sellGoldUrl) return browser def sellGold(): print('开始卖出') browser = openJdjyGold() time.sleep(2) # 已经到卖出的页面了 # 全部卖出的文字按钮，可以优化为 find_elements_by_class_name sellAllBtn = browser.find_elements_by_css_selector( "#app > div > div.inputBox > div.input_content > div.input-row.flex.flex-align-center > p") sellAllBtn[0].click() # 点一下卖全部，填入数量 time.sleep(0.5) # 勾选我已阅读xxx checkIHaveReadRules = browser.find_element_by_class_name("check-icon") checkIHaveReadRules.click() time.sleep(0.5) # 卖出页面下方的 立即卖出 startSellBtn = browser.find_element_by_class_name("jrm-common-btn") startSellBtn.click() time.sleep(2) # 然后是输入密码，找到全部密码按键存到dict passwordBtnDict = {} allPasswordBtn = browser.find_elements_by_class_name("sys-itemW") for btnItem in allPasswordBtn: if btnItem.text != '': # 有两个按键用不上 passwordBtnDict[btnItem.text] = btnItem payPassword = "xxxxxxxxxxxxxxx" # 支付密码，不要泄露了............................. for bitPwd in payPassword: passwordBtnDict[bitPwd].click() # 输入完最后一位，就自动确定了 # 然后忘了还有没有进一步的确定。。。。。。 time.sleep(10) sendDingtalkNotify('完成卖出') browser.quit() def autoSellGold(expectPrice): while True: try: latestPrice = getLatestPrice() if latestPrice > expectPrice: sendDingtalkNotify('''最新价{}元/g，高于预期的{}元/g，准备全部卖出'''.format(latestPrice, expectPrice)) sellGold() sys.exit(0) else: print('未达预期', expectPrice, '，不卖') except Exception as e: traceback.print_exc() sendDingtalkNotify('京东积存金自动交易出错，需要处理') sys.exit(1) finally: time.sleep(30) def sendDingtalkNotify(msg): print('sendDingTalkMsg', msg) url = 'https://oapi.dingtalk.com/robot/send?access_token=xxxxxxxxxxxxxxx' headers = { 'Content-Type': 'application/json' } data = { "msgtype": "text", "text": { "content": "[bot]" + msg + "@xxxxxxxxxxxxxxx" }, "at": { "atMobiles": ["xxxxxxxxxxxxxxx"], "isAtAll": False } } response = requests.post(url=url, headers=headers, json=data) print(response.content) if __name__ == '__main__': buyPrice = 383 # 买入价格，如果想不亏的话，需要的涨幅应该是手续费0.3% minimumPrice = round(buyPrice * 1.003, 3) print('''{}买入的话，最少应该{}才能卖'''.format(buyPrice, minimumPrice)) expectPrice = minimumPrice * 1.01 # 期望价格，可以自己改一下 autoSellGold(expectPrice)
