【问题描述】：

我正在尝试编写一个 python 脚本来帮助我远程安装主题。不幸的是，上传部分效果不佳，尝试使用请求的 POST 助手来完成。

成功上传的 HTTP 标头如下所示：

http://127.0.0.1/wordpress/wp-admin/update.php?action=upload-theme

为 WP 创建一个简单的会话，以便稍后用于上传：

global wp_session

def wpCreateSession(uname, upassword, site_link):
    """
    :param uname: Username for the login.
    :param upaswword: Password for the login. 
    :param site_link: Site to login on.
    :return: Returns a sessions for the said website.
    """
    global wp_session
    wp_session = requests.session()
    wp_session.post(site_link, data={'log' : uname, 'pwd' : upassword})

要将上述文件上传到 WP，使用 wp_session 全局：

def wpUploadTheme(file_name):

    global wp_session

    try:
        with open(file_name, 'rb') as up_file:
            r = wp_session.post('http://127.0.0.1/wordpress/wp-admin/update.php', files = {file_name: up_file})
            print "Got after try."
    finally:
        up_file.close()

最后一点是它不起作用的地方，上传不成功，我返回到 WordPress 的基本 404。

我也试过 requests_toolbelt MultiPart_Encoder 无济于事。

问题：'requests' POST 文件在尝试上传时失败

检查您的files dict，您的dict 无效

files = {file_name: up_file}

也许你需要一个完整的files dict，例如：

files = {'themezip': ('oedipus_theme.zip', 
                       open('oedipus_theme.zip', 'rb'), 
                      'application/octet-stream', {'Expires': '0'})}

来自docs.python-requests.org
files = {'file': open('test.jpg', 'rb')}
requests.post(url, files=files)
