RPC static class: The RPC method only mentions the role of the method, but the specific implementation is not mentioned. The specific implementation involves the static RPC class. The RPC class has five static internal classes: Rpc. clientcache:Used to cache c

do not advertise, just do it quietly. Because it is your own business, others do not know your situation, it is almost impossible to help you achieve the dream. Never show off vanity, and don't give up your dreams because of the comments of others. In fact, the best state, is to adhere to their own dreams, listen to the advice of the predecessors, as far as possible less detours and fewer wrong steps. Few people will really understand you, do not be

Less-6The difference between LESS6 and LESS5 is that the ID parameter is processed by the LESS6 when the ID parameter is passed to the server. This can be seen from the source code.$id = ' "'. $id. '";$sql = "SELECT * from users WHERE id= $id LIMIT 0,1";So our strategy in this relationship is the same as the LESS5. You just need to ' replace '.Here we demonstrate one of the payloadHttp://127.0.0.1/sqllib/

the Mount namespace by switching to Rootfs, but the other namespaces still have only the default content. In the actual container, we need to configure the container's entire environment before it can run the user process. For example, we need to set up the network, switch to the correct UID before running the process, and set some other necessary restrictions (such as the ability to use dropping and set rlimits), and so on. These jobs may make our program more than 100 lines of code.Fifth Step

20 regular expressions are required (you can write less than 1,000 lines of code), and rows of Regular Expressions A regular expression (regular expression) describes a string matching pattern, it can be used to check whether a string contains a seed string, replace matched substrings, or retrieve substrings that meet certain conditions from a string. In the column directory, *. txt in dir *. txt or ls *. t

We set the Mount namespace by switching to Rootfs, but the other namespaces still have only the default content.

You can write less than 1000 lines of code if you know the 20 regular expressions. Regular Expressions, a very old and powerful text processing tool, can quickly implement a very complex business logic by simply using a very short expression statement. Mastering regular expressions can greatly improve your development efficiency. The following are the 20 regular expressions that are frequently used in front
