Question

我创建的字典不是我想要的输出，我不知道我的代码有什么问题。

代码如下：

hostInfoDict = {
'192.168.247.62': {80: 'http', 8080: 'http-proxy'}, 
'192.168.247.64': {80: 'http', 8080: 'http-proxy'}, 
'192.168.247.74': {80: 'http', 8080: 'http-proxy'}
}

for host, hostInfo in hostInfoDict.items():

    httpHostStatusDict = {}

    for port in hostInfo.keys():
        urls = 'http://' + host + ":" + str(port) + '/thredds/catalog.html'
        #print(urls)
        try:
            r = requests.get(urls, timeout=0.5, allow_redirects=False)
            #print(urls, r.status_code)
        except requests.exceptions.HTTPError:
            """An HTTP error occurred."""
            pass
        except requests.exceptions.ConnectionError:
            """A Connection error occurred."""
            pass
        except requests.exceptions.Timeout:
            """
            The request timed out while trying to connect to the remote server.

            Requests that produced this error are safe to retry.
            """
            pass
        except requests.exceptions.RequestException:
            """
            There was an ambiguous exception that occurred while handling your request.
            """
            pass

        try:
            if urls not in httpHostStatusDict:
                httpHostStatusDict[urls] = str(r.status_code)
        except:
            pass
    print(httpHostStatusDict)

以上代码的输出如下所示。它们是分开的，而不是整个字典。

{'http://192.168.247.62:80/thredds/catalog.html': '200', 'http://192.168.247.62:8080/thredds/catalog.html': '200'}
{'http://192.168.247.64:80/thredds/catalog.html': '404', 'http://192.168.247.64:8080/thredds/catalog.html': '404'}
{'http://192.168.247.74:80/thredds/catalog.html': '200', 'http://192.168.247.74:8080/thredds/catalog.html': '200'}

预期输出为

{
 {'http://192.168.247.62:80/thredds/catalog.html': '200'},
 {'http://192.168.247.62:8080/thredds/catalog.html': '200'},
 {'http://192.168.247.64:80/thredds/catalog.html': '404'}, 
 {'http://192.168.247.64:8080/thredds/catalog.html': '404'},
 {'http://192.168.247.74:80/thredds/catalog.html': '200'}, 
 {'http://192.168.247.74:8080/thredds/catalog.html': '200'}
}

这是一个Python REQUEST项目：）我认为这是一个代码问题，因此我认为您不需要安装该库。感谢您的帮助。

您应该在第一个for循环之前放置httpHostStatusDict = {}，并在整个第一个for循环之后打印。
