Golang API
Golang NET package has a very convenient API for us to use, this API can be divided into Addr,listen,connection,dialer,ip and other network APIs, such as DNS API, etc. There are no other Web APIs (mainly self-study _).
Addr mainly have ipaddr,tcpaddr,udpaddr and unixaddr, the main is different address, this is the basis of network programming, no address i
Php simply queries the database and returns json data, while php returns json data. Php simply queries the json data returned by the database. Code 1 of the sample code returned by the php database: Set the returned json format header (content-type: applicationjson; charsetutf8 ); connect to php to query the database and return json data. The php database returns json data.
Sample Code 1:

} Because the selected "test function" only satisfies the displacement boundary condition, the selection condition of "test function" is very broad. However, it is very important to choose a reasonable test function for different test functions to obtain the final result. For example, for pure curved simply-supported beams, the displacement boundary condition is zero at 0 and L, and the displacement shape should be in the middle, and then gradually re

Simply talk about Unicode and UTF8 encoding in PHP, Unicodeutf8
Re-recognize Unicode and UTF8 encoding
Until today, to be exact, I just knew that UTF-8 encoding and Unicode encoding are not the same, there is a difference between the embarrassingThere is a certain connection between them, to see the difference between them:The length of the UTF-8 is not necessarily, it can be 1, 2, 3 bytesUnicode length must be 2 bytes (USC-2)UTF-8 can and Unicode co
Simply talk about the include, include_once, require, and require_once statements in PHP, Requireonceinclude
1.include statements
Use the Include statement to tell PHP to extract a specific file and load its entire contents
2.include_once statements
Each time you use the INCLUDE statement, it will re-import the requested file, even if the file has already been imported. For example Assuming that the fileinfo.php file contains many functions, we use
Use Lua to simply encrypt or decrypt files. Note that the decrypted key is the reverse order of the encrypted key:
1 require ‘bit‘ 2 3 local encode = function(inpath, outpath, key) 4 local inf = assert(io.open(inpath, "rb")) 5 local outf = assert(io.open(outpath, "wb")) 6 7 if (type(key) ~= "string") or (string.len(key) == 0) then 8 key = "x" 9 end10 11 local temp = nil12 local data = inf:read(1)13 while data do1
Simply talk about the difference between Ob_flush and flush in PHP, Ob_flushflush
Ob_flush/flush's description in the manual, is to refresh the output buffer, and also need to be used, so it will cause many people confused ...
In fact, the two of them are different objects, in some cases, flush does not do anything at all.
The Ob_* series function is the output buffer that operates PHP itself.
So, Ob_flush is the buffer that refreshes PHP itself.

Hive itself does not have a specific data storage format and does not index the data, only the column separators and row separators in the hive data are told when the table is created, and hive can parse the data. So importing data into a hive table simply moves
