Python mocking requests.get内容和iter_行（）

我试图模拟一个在内部使用它的对象的streamed requests.get函数

我特别需要测试以下方法：

class MyObject(object)
    def __iter__(self):
        payload = {"op": "OPEN"}
        response = requests.get("http://" + self.parsed_uri.uri_path, params=payload, stream=True)
        return response.iter_lines()

    def read(self, size=None):
        if not size or size < 0:
            payload = {"op": "OPEN", "offset": self.offset}
            self.offset = 0
        else:
            payload = {"op": "OPEN", "offset": self.offset, "length": size}
            self.offset = self.offset + size
        response = requests.get("http://" + self.parsed_uri.uri_path, params=payload, stream=True)
        return response.content

我正在尝试实现mocked_请求，但不幸的是，我无法让它工作。可以这样使用模拟库吗？模拟请求得到的

应该是什么样子？
UPD。如果没有完整的示例，就无法说出代码的真正错误。我如何使用
响应解决此问题
模块：

import requests
import unittest
import responses


class Foo(object):
    def __init__(self, uri):
        self.uri = uri

    def __iter__(self):
        payload = {"op": "OPEN"}
        response = requests.get("http://" + self.uri, params=payload,
                                stream=True)
        return response.iter_lines()


class TestFoo(unittest.TestCase):
    @responses.activate
    def test_iter_lines(self):
        responses.add(responses.GET, "http://local.host/", body='abc\n123')
        r = iter(Foo("local.host"))
        self.assertEqual(r.next(), "abc")
        self.assertEqual(r.next(), "123")

if __name__ == '__main__':
    unittest.main()

另外，在调用此函数之前，您是否希望返回迭代器

self.assertEqual(object.next(), "123")

它只包含
self.offset
，
self.parsed_uri
，没有其他内容。你是说
\uuuu init\uuu
？那么
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。现在唯一的问题是，它在Python3
b“abc”
中返回字节字符串，在Python2
“abc”
中返回普通字符串。
self.assertEqual(object.next(), "123")
