your 'www' directory should be in the same directory of 'your-source.py' 150 | ``` 151 | 152 | ## Documentation 153 | 154 | For normal usages, you only need to know `class EasyPyServer`, `class Method`, `class Request`,`class Response`, `class ResponseConfig` 155 | .You can easily import them by 156 | ```python 157 | from easy_py_server import EasyPyServer, Method, Request, Response, ResponseConfig 158 | ``` 159 | 160 | ### Creating Server 161 | ```python 162 | from easy_py_server import EasyPyServer 163 | # create 164 | eps = EasyPyServer(listen_address="0.0.0.0", port=8090) 165 | # run 166 | eps.start_serve(blocking=True) 167 | ``` 168 | 169 | ### Registering Service 170 | 171 | You can register a service by adding a decorator such as `@route`, `@get`, `@post` to your function. Feel free 172 | to use these decorators, they will register your functions as callback without changing the original code of your definition. Among them, decorator `@route` has full support for different methods: 173 | 174 | ```python 175 | @eps.route(path="/path/to/your/api", methods=[Method.GET]) 176 | def f(request: Request): 177 | return Response() 178 | ``` 179 | You can bind `GET`/`POST` methods with a simpler `@get`/`@post` like it's shown in the demo code: 180 | ```python 181 | @eps.get("/api") 182 | def demo(a: int, b: int): 183 | return dict(success=True, content="%d + %d = %d" % (a, b, a + b)) 184 | ``` 185 | You can use the decorators to specify the response's `Content-Type` or customize headers. For example, you can set `Access-Control-Allow-Origin: *` to enable cross site accessing. 186 | ```python 187 | @eps.post("/cross", ResponseConfig(headers={'Access-Control-Allow-Origin': '*'})) 188 | def cross_access(): 189 | return "post allow" 190 | ``` 191 | 192 | > note: Decorators are the recommended way to register your service, but you can also 193 | > use the naive .add_request_listener() to do it. 194 | 195 | 196 | ```python 197 | from easy_py_server import EasyPyServer, Method 198 | def func(): 199 | pass 200 | httpd = EasyPyServer() 201 | httpd.add_request_listener("/",[Method.GET],func) 202 | 203 | ``` 204 | ### Parameter Injection 205 | 206 | Parameters such as `a`, `b` and `request` shown above can be automatically injected to your service function when it is requested. 207 | These parameters will be parsed from the HTTP request depending on the names of your variables. For instance, you can 208 | access `demo` function (shown above) and inject parameters `a` and `b` by visiting the URL: 209 | ```text 210 | http://:/api?a=1&b=12 211 | ``` 212 | The value of parameter `a` will be parsed as 1 and as 12 for `b`. 213 | 214 | #### Specifying Types 215 | The parameters will be interpreted as `string` object by default. You can change this behavior by specifying explict 216 | types to make them automatically converted to your desired types. 217 | ```python 218 | # post multipart file 219 | @httpd.post("/multipart") 220 | def post(save_name: str, file: MultipartFile): 221 | save_path = '{}.txt'.format(save_name) 222 | file.save(save_path) 223 | return dict(success=True, message="save to {}".format(save_path)) 224 | ``` 225 | #### Special types 226 | * `Request`: http request object, encapsulating `session`, `parameters` ,`cookies` 227 | * `MultipartFile`: supporting for uploading files. 228 | 229 | #### Access session and cookies 230 | They are encapsulated inside the `Request` object, so you can get them by getting a `Request` object first. It's defined in `datastruct.py`, you can check this file for more details. 231 | ```python 232 | @httpd.get("/") 233 | def index(req: Request): 234 | req.get_session() 235 | req.set_cookie() 236 | return None 237 | ``` 238 | 239 | ### Automatic Response Construction 240 | You can return a python object without explicitly constructing `Response` object. They'll be automatically converted a correct HTTP response to the client. The supporting objects are listed as following: 241 | 242 | * dict -> json 243 | * string -> text 244 | * PIL -> image 245 | * bytes -> octet-stream 246 | * other -> octet-stream 247 | 248 | As an example, you can easily return a PIL image: 249 | ```python 250 | from PIL import Image 251 | @httpd.get("/show_image") 252 | def show_image(image_path: str): 253 | try: 254 | img = Image.open(image_path, mode='r') 255 | except IOError as e: 256 | return None 257 | return img 258 | ``` 259 | 260 | 261 | ## More 262 | * Supporting for `ipv6` and `https` will come soon. 263 | -------------------------------------------------------------------------------- /test/test_server.py: -------------------------------------------------------------------------------- 1 | import unittest 2 | from easy_py_server import EasyPyServer, Method, Request, ResponseConfig 3 | import requests 4 | import multiprocessing as mt 5 | 6 | 7 | def mock_func(): 8 | print("ok") 9 | 10 | 11 | class TestEasyPyServer(unittest.TestCase): 12 | def test_reuse_address(self): 13 | self.assertTrue(EasyPyServer.allow_reuse_address) 14 | 15 | def test_add_listener(self): 16 | class Mock(object): 17 | def __init__(self): 18 | self.listeners_dic = {} 19 | 20 | mock = Mock() 21 | url = "/i" 22 | EasyPyServer.add_request_listener(mock, url, [Method.GET, Method.OPTIONS], mock_func) 23 | # print(mock.listeners_dic) 24 | self.assertTrue(len(mock.listeners_dic) == 1) 25 | self.assertTrue(mock.listeners_dic[url][Method.GET][0] == mock_func) 26 | self.assertTrue(Method.POST not in mock.listeners_dic[url]) 27 | self.assertTrue(mock.listeners_dic[url][Method.OPTIONS][0] == mock_func) 28 | 29 | 30 | class FunctionalTest(unittest.TestCase): 31 | 32 | def setUp(self) -> None: 33 | if hasattr(self, 'server') and self.server is not None: 34 | return 35 | self.port = 8999 36 | self.addr = 'localhost' 37 | self.server = EasyPyServer(self.addr, port=self.port) 38 | 39 | def set(data, r: Request): 40 | r.set_session_attribute('data', data) 41 | return "ok" 42 | 43 | @self.server.get('/get') 44 | def get(r: Request): 45 | return r.get_session_attribute('data') 46 | 47 | @self.server.get('/sum_2/:a/and/:bb') 48 | def sum_2(a: int, bb: int): 49 | return a + bb 50 | 51 | @self.server.get('/sum_list') 52 | def sum_list_get(arr: list): 53 | return "get" + str(sum(arr)) 54 | 55 | @self.server.post('/sum_list') 56 | def sum_list_post(arr: list): 57 | arr = [float(a) for a in arr] 58 | return "post" + str(sum(arr)) 59 | 60 | # 自定义header 61 | @self.server.post("/cross", ResponseConfig(headers={'Access-Control-Allow-Origin': '*'})) 62 | def cross_access(): 63 | return "post allow" 64 | 65 | self.server.add_request_listener('/set', [Method.GET], set) 66 | self.thread = self.server.start_serve(blocking=False) 67 | 68 | def test_static(self): 69 | base_url = f'http://{self.addr}:{self.port}' 70 | 71 | def test_file(url, expect_text, expect_content_type='text/html'): 72 | rst = requests.get(url) 73 | self.assertEqual(rst.status_code, 200) 74 | self.assertEqual(rst.headers['Content-Length'], str(len(rst.text))) 75 | self.assertEqual(rst.headers['Content-Type'], expect_content_type) 76 | self.assertEqual(rst.text, expect_text) 77 | 78 | def test_file_not_exist(url): 79 | rst = requests.get(url) 80 | self.assertEqual(rst.status_code, 404) 81 | self.assertEqual(rst.headers['Content-Type'], 'text/html;
