一、抓包内容

通过F12获取web网页中query-queue-rate的内容：

web抓取的包.png

二、分析

该包中包含：
General：通用信息
Response Headers：返回包头
Request Headers：请求包头
-Cookie：加密
-Host：对应的host
Form Data：请求的Data信息

三、python的request该如何填写

    DATA = {'exact_key': '091198',
            'sys_key': 'ipo',
            'biz_key': 'ipo_stock'}
    Cookie = 'uid=100001; locale=zh-cn; cipher_device_id=1600167818814682; device_id=1600167818814682; sensorsdata2015jssdkcross=%7B%22distinct_id%22%3A%22174917ebf429fd-09a06f098fff8e-3323767-2073600-174917ebf43114%22%2C%22first_id%22%3A%22%22%2C%22props%22%3A%7B%7D%2C%22%24device_id%22%3A%22174917ebf429fd-09a06f098fff8e-3323767-2073600-174917ebf43114%22%7D; web_sig=j%2FTZLVEClzkZoTylihiTTtjc2hqUJPLXLMvSZi4K3swNA2EqErrY4DX3H78lQ20q9F2EbzyETaRl994NVuZwFt37eAfDpciiVAtaSVDg6ptGmw0F1ak%2F6uFUm%2BYEK%2FLk'
    host = 'https://queue.futuhk.com/queue/query-queue-rate'
    r = requests.post(host, data=DATA, headers={'Host': 'queue.futuhk.com', 'Cookie': Cookie}, verify=False)

四、注意事项

• 1. Cookie、host需要以字典的形式写入到header里面
• 2. 不能将cookies作为字典形式，传入到request中

#错误写法
Cookie ={ 'Cookie': 'uid=100001; locale=zh-cn; cipher_device_id=1600167818814682; device_id=1600167818814682; sensorsdata2015jssdkcross=%7B%22distinct_id%22%3A%22174917ebf429fd-09a06f098fff8e-3323767-2073600-174917ebf43114%22%2C%22first_id%22%3A%22%22%2C%22props%22%3A%7B%7D%2C%22%24device_id%22%3A%22174917ebf429fd-09a06f098fff8e-3323767-2073600-174917ebf43114%22%7D; web_sig=j%2FTZLVEClzkZoTylihiTTtjc2hqUJPLXLMvSZi4K3swNA2EqErrY4DX3H78lQ20q9F2EbzyETaRl994NVuZwFt37eAfDpciiVAtaSVDg6ptGmw0F1ak%2F6uFUm%2BYEK%2FLk'}
requests.post(host, data=DATA, cookies=Cookie, headers={'Host': 'queue.futuhk.com'}, verify=False)

此时服务器那边因为字段对应不上，uid会解析错误

• 3. 不能将cookies以字符产形式，传入到request中

#错误写法
Cookie ='uid=100001; locale=zh-cn; cipher_device_id=1600167818814682; device_id=1600167818814682; sensorsdata2015jssdkcross=%7B%22distinct_id%22%3A%22174917ebf429fd-09a06f098fff8e-3323767-2073600-174917ebf43114%22%2C%22first_id%22%3A%22%22%2C%22props%22%3A%7B%7D%2C%22%24device_id%22%3A%22174917ebf429fd-09a06f098fff8e-3323767-2073600-174917ebf43114%22%7D; web_sig=j%2FTZLVEClzkZoTylihiTTtjc2hqUJPLXLMvSZi4K3swNA2EqErrY4DX3H78lQ20q9F2EbzyETaRl994NVuZwFt37eAfDpciiVAtaSVDg6ptGmw0F1ak%2F6uFUm%2BYEK%2FLk'
requests.post(host, data=DATA, cookies=Cookie, headers={'Host': 'queue.futuhk.com'}, verify=False)

此时接口会应为传入参数类型错误，报异常
