示例1: test_setdefault
# 需要导入模块: from tornado.httputil import HTTPHeaders [as 别名]
# 或者: from tornado.httputil.HTTPHeaders import setdefault [as 别名]
def test_setdefault(self):
headers = HTTPHeaders()
headers['foo'] = 'bar'
# If a value is present, setdefault returns it without changes.
self.assertEqual(headers.setdefault('foo', 'baz'), 'bar')
self.assertEqual(headers['foo'], 'bar')
# If a value is not present, setdefault sets it for future use.
self.assertEqual(headers.setdefault('quux', 'xyzzy'), 'xyzzy')
self.assertEqual(headers['quux'], 'xyzzy')
self.assertEqual(sorted(headers.get_all()), [('Foo', 'bar'), ('Quux', 'xyzzy')])示例2: set_default_headers

# 或者: from tornado.httputil.HTTPHeaders import setdefault [as 别名]
