'''
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:\Users\wangzhiqiang\Desktop\desktop\duoceshi_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
