本节尝试从client发送json到服务器，然后服务器根据内容响应

１.测试客户端发送与接收输出

import json,falconclass ObjRequestClass: def on_get(self,req,resp): resp.status = falcon.HTTP_200 data = json.loads(req.stream.read()) content = { 'name':'falcon', 'age':30 } resp.body=json.dumps(data)api = falcon.API()api.add_route('/test',ObjRequestClass())

req.stream.read() #读取客户端请求内容

发送测试请求，我用httpie，喜欢用postman的在Body,raw中添加即可。

http get localhost:8080/test name="hello"

注意发送时用双引号，不要用单引号。单引号会报错。

一切正常能看到如下输出：

HTTP/1.1 200 OKContent-Length: 17Content-Type: application/jsonDate: Fri, 08 Nov 2019 03:39:59 GMTServer: waitress{ "name": "hello"}２.尝试根据发送内容获取不同结果

{"method":"get-name"}

import json,falconclass ObjRequestClass: def on_get(self,req,resp): resp.status = falcon.HTTP_200 data = json.loads(req.stream.read()) content = { 'name':'falcon', 'age':30 } value={} if data["method"]=="get-name": value['value']=content['name'] else: value['value']=None resp.body=json.dumps(value)api = falcon.API()api.add_route('/test',ObjRequestClass())

httpie测试

http get localhost:8080/test falcon_test:api method="get-name" #结果正常http get localhost:8080/test falcon_test:api method="get-names" #结果为null３.添加不同http状态

import json,falconclass ObjRequestClass: def on_get(self,req,resp): resp.status = falcon.HTTP_200 data = json.loads(req.stream.read()) content = { 'name': 'falcon', 'age': 30 } value = {} if "method" not in data: #检测内容是否包含请求信息 resp.status == falcon.HTTP_501 else: if data["method"] == "get-name": value['value'] = content['name'] elif data["method"] == "get-age": value['age'] = content['age'] else: resp.status = falcon.HTTP_404 value['value'] = None resp.body = json.dumps(value)api = falcon.API()api.add_route('/test',ObjRequestClass())

req.stream 可用
