1.URLError The reasons for the Urlerror: (1) No connection to the network, that is, the computer can not access (2) Not connected to a specific server (3) server does not exist Import urllib.request import urllib.error from urllib.request import Urlopen request= Urllib.request.Request (' http://www.xxxxxx.com ') try: urllib.request.urlopen (request) except Urllib.error.URLError as E: print (E.reason)D:\Anaconda3\python.exe d:/dazhongdianping/position.py [Errno 11004]

First of all, the HTTP exception handling problem. When Urlopen cannot handle a response, a urlerror is generated. However, the usual Python APIs such as Valueerror,typeerror can also be generated. Httperror is a subclass of Urlerror that is typically generated in a specific HTTP URL. 1.URLError Typically, urlerror occurs without a network connection (not routed to a specific server), or if the server does not exist. In this case, the exception also has the "reason" attribute, which is a t

Introduction: Learn about the pros and cons of tight coupling and loosely coupled Web Services, and the scale changes brought about by tight coupling. This article provides examples of criteria for determining the performance of tightly coupled Web Services during testing. Introduction My Developerworks series articles, use SLAs in a WEB services context, discuss how to eliminate the risks posed by vulnerabilities and how to integrate WEB services into a service level agreement AGREEMENT,SLA)

standardization of standards, the choice of manufacturer and product is transparent to system core code. Even upgrading or replacing specific system software (such as migrating Web servers from tomcat to resin) does not require changes to the core application modules.* Rich in both productsDevelopment or purchase ("Build or buy") is an important consideration when building a system. The use of off-the-shelf products can greatly shorten the system implementation cycle, this factor for the attrac

systems of communication and collaboration. Of course, the way to achieve this is far more than WCF one, such as in the Win32 era, often using mapped memory files to achieve interoperability between processes, and in Windows programs, the use of Windows Messaging WM can also achieve the communication problems between different processes, but these have limitations, Because they are not good at solving Cross-platform, cross network issues while WCF can.

Zero-Basic python crawler-based HTTP Exception Handling and python exception handling Let's talk about HTTP exception handling.When urlopen cannot process a response, urlError is generated.However, Python APIs exceptions such as ValueError and TypeError are also generated at the same time.HTTPError is a subclass of urlError, which is usually generated in a specific HTTP URLs. 1. URLErrorGenerally, URLError is generated when there is no network connection (no route to a specific server) or the se

Be able to access the MySQL database. Goapp cannot access the Javaapp application through Javaapp. Enter Javaapp and Goapp this container, can ping each other through. Problem analysis There are two key points in the phenomenon: In a container, all pings can be interconnected. Explain

components or environments can be configured or deployed in the installation package, but debugging will not be used directly in them anyway.(ii) similar to the "Ubuntu under the Pycharm run debugging Odoo 8.0 possible problems" way to set the Pycharm Debug configuration parameters.Because it is a temporary development environment, I did not download the source debugging, but use the green version, add the green version of the directory in Pycharm, and then debug debugging Openerp-server file.(

1.URLError First explain the possible causes of Urlerror: Network is not connected, that is, the computer cannot surf the internet Cannot connect to a specific server Server does not exist In the code, we need to surround and catch the corresponding exception with the try-except statement. Here's an example of how it's going to feel Import Urllib2 Requset = Urllib2. Request (' http://www.xxxxx.com ') Try: Urllib2.urlopen (requset) except URLLIB2. Urlerror, E: print E.reason

This article mainly introduces how to handle URLError exceptions in Python. This article also lists some common HTTPError situations. For more information, see 1. URLError First, explain the possible causes of URLError: No network connection, that is, the local machine cannot access the Internet The specified server cannot be connected. The server does not exist. In the code, we need to use the try-retry T statement to enclose and capture the corresponding exceptions. The following is a
