Instruction

install python 3

```
borrow the book you want to download

start downloading
```
python src\download.py [options]
```
There 3 pairs of options you can use:
- c/i: use Cached cookie and request example OR let user Input cookie and request example [default]
- r/n: Restore to downlaod pages in fail.log OR download a New book with a page range [default]
- p/d: use Proxy to download [default] OR Directly download

here are some examples:

python src\download.py        (download a new book)
python src\download.py cr     (download pages that weren't download correctly last time)
python src\download.py d      (download without using proxy)

NOTE: Using proxy is set by DEFAULT. You can config your proxy in the source code:

PROXY = {
    'http': 'http://127.0.0.1:4780', # replace with your own proxy
    'https': 'http://127.0.0.1:4780', # replace with your own proxy
}

So, If you don't want to use proxy, don't forget to add option d in the command.

if you download a new book, for example, you type python src\download.py in the command line. You will be asked to input cookie and request example:
```
cookie > (you paste your cookie here)
request example > (you paste your request example url here)
page range > (you type your the page range here [format: begin-end]. note that the `begin` can be omit)
```
Then, the script will start downloading. You can take a cup of coffee till it finishes.
