python requests实现multipart/form-data 请求

使用python的requests 发送multipart/form-data 请求实现模拟登录

设置请求头

headers = {

    "Accept": "application/json, text/javascript, */*; q=0.01",
    "Accept-Encoding": "gzip, deflate, br",
    "Accept-Language": "zh-CN,zh;q=0.9",
    "Connection": "keep-alive",
    "Content-Length": "797",
    # "Content-Type": "multipart/form-data; boundary=----WebKitFormBoundarywapmYW7C1gSTBbpK",
    "Cookie": "PHPSESSID=xxxxxxxxxxxxxxxxxxxxxxx",
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36",
    "X-Requested-With": "XMLHttpRequest"
}

data={
        "username": "username",
        'nickname': "password",
}

发起post请求、获取返回消息,python3 requests方法中内置json参数。

    res = requests.post(url, json=data, headers=headers)
    print(res)
    print(res.text)

总结

当出现不成功时，发现其他的没什么问题，那就检查下Content-Type，Content-Length删掉或者增加。
