用了些requests模块，主要是requests.request、requests.get和requests.post

import jsonimport requestsurl='http://localhost:8888/'response=requests.get(url)#打印响应内容print('response.text:',response.text)print('response.content.decode():',response.content.decode())print('response.content:',response.content)print('response.json():',response.json())print('----------------------------------')#打印相应内容类类型print('response.text:',type(response.text))print('response.content.decode():',type(response.content.decode()))print('response.content:',type(response.content))print('response.json():',type(response.json()))print('----------------------------------')#判断相应内容是否相等print(response.text==response.content.decode())print(response.json()==response.content.decode())print(json.loads(response.content.decode())==response.json())

运行结果：

response.text: {"name": 1, "age": 18}

response.content.decode(): {"name": 1, "age": 18} response.content: b'{"name": 1, "age": 18}' response.json(): {'name': 1, 'age': 18} ---------------------------------- response.text: <class 'str'> response.content.decode(): <class 'str'> response.content: <class 'bytes'> response.json(): <class 'dict'> ---------------------------------- True False True

------------------------------------------------------------------------------------------------------------------

关于json方法：

服务端返回内容有限制，不然response.json()方法会报错

客户端代码：

import tornado.ioloopimport tornado.webclass MainHandler(tornado.web.RequestHandler):    # 定义tornado的get方法    def get(self):        # self.write('{"name":1,"age":18}')#可以用json        # self.write({"name":1,"age":18})#可以用json        self.write({'name':1,'age':18})#可以用json        # self.write("{'name':1,'age':18}")#json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)        # self.write("{'name':1,'age':18}")#json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)        # self.write("test")#json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)        # self.write('test')#json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)        # self.write([1,2,3])#json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)        # self.write(123)#json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)    #定义tornado的post方法    def post(self, *args, **kwargs):        self.write({'name':1,'age':18})#可以用jsondef make_app():    return tornado.web.Application([        (r"/", MainHandler),    ])if __name__ == "__main__":    app = make_app()    app.listen(8888)    tornado.ioloop.IOLoop.current().start()

对比requests.request方法和requests.get、requests.post方法的区别，感觉requests.request就是两这个汇总，手动传方法就行了

import jsonimport requestsurl='http://localhost:8888/'response=requests.get(url)response2=requests.request('get',url)response3=requests.request('post',url)#判断response和response2print('response.text:',response.text==response2.text)print('response.content.decode():',response.content.decode()==response2.content.decode())print('response.content:',response.content==response2.content)print('response.json():',response.json()==response2.json())#判断response和response3print('response.text:',response.text==response3.text)print('response.content.decode():',response.content.decode()==response3.content.decode())print('response.content:',response.content==response3.content)print('response.json():',response.json()==response3.json())

运行结果：

response.text: True

response.content.decode(): True response.content: True response.json(): True response.text: True response.content.decode(): True response.content: True response.json(): True

这个结果是返回结果完全一样的，但是有api接口返回竟然是随机的。。。

比如天气api的这个接口

代码如下：

import jsonimport requestsurl='http://v.juhe.cn/weather/index'data={'cityname':'北京','key':'4ddab89a84997b92d16be8451a877a71'}response=requests.get(url,params=data)response1 = requests.request('GET', url, params=data)print(response.json() == response1.json())
