requests 提交form-data

一个网站的数据是form-data形式提交的

直接post会失败，实现

def get_after_data(before_data):
    headers = {
        'Content-Type': 'multipart/form-data; boundary=----WebKitFormBoundaryuILbHAxyzWMIAXn2'
    }
    params = OrderedDict([
        ("type", (None, 'jyzs')),
        ("val[]", (None, 1111111)),
        ("val[]", (None, None)),
    ])
    res = requests.post('http://ajuntools.hz.taeapp.com/mainIndex/getdata.html', files=params).json()

请求成功，返回结果为：

{"data":["30187443"],"code":"200","type":"jyzs"}

第二种方式，使用urllib3的encode_multipart_formdata方法

from collections import OrderedDict
from urllib3 import encode_multipart_formdata

params = OrderedDict([("username", (None, '130533193203240022', 'multipart/form-data')),
                      ("password", (None, 'qwerqwer', 'multipart/form-data')),
                      ('captchaId', (None, 'img_captcha_7d96b3cd-f873-4c36-8986-584952e38f20', 'multipart/form-data')),
                      ('captchaWord', (None, 'rdh5', 'multipart/form-data')),
                      ('_csrf', (None, '200ea95d-90e9-4789-9e0b-435a6dd8b57b', 'multipart/form-data'))])
m = encode_multipart_formdata(params, boundary='----WebKitFormBoundaryKPjN0GYtWEjAni5F')

print(m[0])

输出结果：

b'------WebKitFormBoundaryKPjN0GYtWEjAni5F\r\nContent-Disposition: form-data; name="username"\r\nContent-Type: multipart/form-data\r\n\r\n130533193203240022\r\n------WebKitFormBoundaryKPjN0GYtWEjAni5F\r\nContent-Disposition: form-data; name="password"\r\nContent-Type: multipart/form-data\r\n\r\nqwerqwer\r\n------WebKitFormBoundaryKPjN0GYtWEjAni5F\r\nContent-Disposition: form-data; name="captchaId"\r\nContent-Type: multipart/form-data\r\n\r\nimg_captcha_7d96b3cd-f873-4c36-8986-584952e38f20\r\n------WebKitFormBoundaryKPjN0GYtWEjAni5F\r\nContent-Disposition: form-data; name="captchaWord"\r\nContent-Type: multipart/form-data\r\n\r\nrdh5\r\n------WebKitFormBoundaryKPjN0GYtWEjAni5F\r\nContent-Disposition: form-data; name="_csrf"\r\nContent-Type: multipart/form-data\r\n\r\n200ea95d-90e9-4789-9e0b-435a6dd8b57b\r\n------WebKitFormBoundaryKPjN0GYtWEjAni5F--\r\n'

第二种方法较为完善，可以自由添加分隔符
