Python请求 - 没有连接适配器

Question

我正在使用Requests:HTTP for Humans library,我得到了这个奇怪的错误,我不知道是什么意思.

No connection adapters were found for '192.168.1.61:8080/api/call'

有人有想法吗？

Answer 1

您需要包含协议方案:

'http://192.168.1.61:8080/api/call'

没有该http://部分,requests不知道如何连接到远程服务器.

Answer 2

还有一个原因,也许你的网址包含一些隐藏字符,例如'\n'.

如果您定义如下所示的网址,则此异常将引发:

url = '''
http://google.com
'''

因为字符串中有'\n'隐藏.网址实际上变成:

\nhttp://google.com\n

Answer 3

就我而言，当我重构 url 时收到此错误，留下错误的逗号，从而将我的 url 从字符串转换为元组。

我的确切错误消息：

    741         # Nothing matches :-/
--> 742         raise InvalidSchema("No connection adapters were found for {!r}".format(url))
    743 
    744     def close(self):

InvalidSchema: No connection adapters were found for "('https://api.foo.com/data',)"

这个错误是这样产生的：

    741         # Nothing matches :-/
--> 742         raise InvalidSchema("No connection adapters were found for {!r}".format(url))
    743 
    744     def close(self):

InvalidSchema: No connection adapters were found for "('https://api.foo.com/data',)"
