The reason for the error is NameResolutionError(self.host,self,e)frome, which is an exception type in the urllib3 library. The reason for this error is that DNS resolution failed, that is, the host name or IP address attempted to be resolved cannot be found. This may be caused by the entered URL address being incorrect or the DNS server being temporarily unavailable. How to solve this error There may be several ways to solve this error: Check whether the entered URL address is correct and make sure it is accessible Make sure the DNS server is available, you can try using the "ping" command on the command line to test whether the DNS server is available Try accessing the website using the IP address instead of the hostname if behind a proxy

The reason for the error is that the ProxySchemeUnknown(proxy.scheme) error of urllib3 is usually caused by the use of an unsupported proxy protocol. In this case, urllib3 does not recognize the proxy server's protocol type and therefore cannot use the proxy for network connections. To resolve this issue, you need to ensure that you are using a supported proxy protocol, such as HTTP or https. How to resolve To resolve this issue, you need to ensure that you are using a supported proxy protocol, such as HTTP or HTTPS. You can solve this problem by setting the proxy parameters of urllib3. If you are using an http proxy, the code example is as follows: importurllib3http

How to use the urllib.request.urlopen() function in Python3.x to send a GET request. In network programming, we often need to obtain data from a remote server by sending an HTTP request. In Python, we can use the urllib.request.urlopen() function in the urllib module to send an HTTP request and get the response returned by the server. This article will introduce how to use

How to use the urllib.request.urlopen() function in Python3.x to send a POST request. In network programming, it is often necessary to send a POST request through the HTTP protocol to interact with the server. Python provides the urllib.request.urlopen() function to send various HTTP requests, including POST requests. This article will introduce in detail how to use urllib.request.urlop

1. Create a new file called request.js and import Axios: importaxiosfrom'axios'; 2. Create a function called request and export it: This will create a function called request and export it Set up a new Axios instance with a base URL. To add timeout settings in a wrapped Axios instance, you can pass the timeout option when creating the Axios instance. exportconstrequest=axios.create({baseURL:'https://example.
