具有多个输入的Web废料并收集所需的总保证金 [英] Web scrap with multiple inputs and collect Total Margin required

问题描述

我的网络链接为:

url = "zerodha.com/margin-calculator/SPAN"

此处提供带有示例值的输入参数，供您参考，如下所示:

Here input parameters with sample values for reference mentioned below:

Exchange - NFO
Product - Options
Symbol - DHFL 27-JUN-19
Option Type - Calls
Strike Price - 120
Net Qty appears automatically as 1500, 

并使用 SELL 按钮，然后单击 ADD 按钮.

and Use SELL Button then Click ADD Button.

我想收集显示在右端的所需总保证金(在上述情况下为 Rs 49,308 ).

I want to collect the Total Margin required (in above case its Rs 49,308) which appears in the right end.

推荐答案

您可以只使用请求.如果观察到您的网络，则可以看到它正在使用选定的有效负载发出POST请求.这就是我的方法:

You can just use requests. If you observe your network, you can see that it is making a POST requests with selected payload. This is how I would do it:

from requests import Session

BASE_URL = 'https://zerodha.com/margin-calculator/SPAN'

payload = {'action': 'calculate',
            'exchange[]': 'NFO',
            'product[]': 'FUT',
            'scrip[]': 'DHFL19AUG',
            'option_type[]': 'CE',
            'strike_price[]':120, 
            'qty[]': 4000,
            'trade[]': 'sell'
}



session = Session()

res = session.post(BASE_URL, data=payload)

data = res.json()

print(data)

我从观察网络获得了URL和有效载荷.这就是您将获得的json形式的数据.

I got the URL and Payload from observing network. This is what you will get as data in json form.

Chrome和python中的结果

Results in chrome and python

只需观察chrome或firefox如何发送和接收数据.然后根据您的要求进行逆向工程.

Just observe how chrome or firefox send and receive data. And reverse engineer with your requests.
