【Python - 接口测试】05实例百度翻译接口测试

接口测试的基本步骤：
1.拿到接口的 url 地址；
2. 查看接口时用什么方式发送
3.添加请求头、请求体
4.发送查看返回结果，校验返回结果是否正确

1.以测试百度翻译接口为例，更多的百度翻译的接口 API 可在百度翻译官网获取到：

import requests
import unittest
import random
import hashlib
import urllib
import json

word = input('请输入你要翻译的词语：')

class BaiduTranslate(unittest.TestCase):

    def setUp(self) -> None:
        # url = 'http://fanyi.baidu.com/v2transapi'
        self.q = word
        self.fromLang = 'en'
        self.toLang = 'zh'

        my_url = '/api/trans/vip/translate'
        # appid 和 secretKey 注册百度翻译开发者可在用户控制台获取到
        self.appid = 'xxxxxxx'
        self.secretKey = 'xxxxxxxx'
        self.salt = random.randint(32768, 65536)
        self.sign = self.appid + self.q + str(self.salt) + self.secretKey

        m1 = hashlib.md5()
        m1.update(self.sign.encode('utf-8'))
        self.sign = m1.hexdigest()
        self.my_url = my_url + '?appid=' + self.appid + '&q=' + urllib.request.quote(self.q) + '&from=' + \
                      self.fromLang + \
                      '&to=' + self.toLang + '&salt=' + str(self.salt) + '&sign=' + self.sign

    def test_translate(self):
    	# 百度翻译的示例文档中用的是 urllib 库，建议使用第三方库 requests 方便点
        r = requests.request('post', url='http://api.fanyi.baidu.com' + self.my_url)
        print('\nr_text_type: ', type(r.text))
        print('r_text: ', r.text)
        r_json = json.loads(r.text)
        print('r_json_type: ', type(r_json))
        print('r_json: ', r_json)

    def tearDown(self) -> None:
        print("测试固件销毁......")

if __name__ == "__main__":
    unittest.main(verbosity=2)

2. 生成测试报告
