    1.请求的url地址:http://127.0.0.1:5000/duoceshi/upload
    2.post请求参数传递的几种方式:
    data:一般用来传递表单类型的参数、默认的请求头是Content-Type:application/x-www-form-urlencoded
    json:用来传递json类型的参数、默认的请求头是Content-Type:application/json
    files:用来上传文件的参数、默认的请求头是Content-Type:multipart/form-data
    3.参数名:(文件名、文件流、文件类型image/png)
    '''
    
    #组建接口的要素:url地址、接口的入参、请求头、接口的请求方法
    
    import requests   #做接口测试的库
    
    #1.定义url地址
    url = 'http://127.0.0.1:5000/duoceshi/upload'
    
    #2.定义接口的入参
    data = {
        'dcs_name':'多测师_王sir',
        'sex':'',
        'age':18
    }
    
    #3.接口的入参为文件  参数名:(文件名、文件流、文件类型image/png)
    file = {
        'pic':('duoceshi_api.png',open(r'C:UserswangzhiqiangDesktopdesktopduoceshi_api.png','rb'),'image/png')
    }
    
    #4.发送接口的请求
    response = requests.post(url=url,data=data,files=file)
    # print(response.text)
    # print(type(response.text))
    print(response.json())   #通过json函数把接口的返回数据转换为字典
    print(type(response.json()))
    运行环境和流程:
    1、前提安装好python
    2、安装flask
       cmd 执行命令 pip install flask
    3、运行http_service.py这个文件
    
    4、就可以通过http://127.0.0.1:5000/duoceshi/upload访问这个接口
       注意点:get请求返回的是上传文件的页面,post请求是上传文件
    5、通过打开upload_page.html进行测试
    6、通过postman或者编写测试代码进行测试
    7、通过Python+Requests库编写测试代码进行测试
