In php, rawurlencode and rawurlencode both encode characters. next I will introduce the differences between urlencode and rawurlencode. if you need to know, refer to urlencode for encoding strings, except all the characters in the original string "-_".

Gob is a serialization/decoding tool with a data structure in the Golang package. In practical applications, there are already a lot of codec tools/packages/libraries, why Golang also need to develop a new Gob? Again a repeating wheel? What did Gob do? What are the advantages of GOB? This article has made a more compr
them from being transmitted to media (like some email systems) use character conversion. For example, if you want to include a password in an ftp url:
Example 1. rawurlencode () Example 1
The code is as follows:
Echo ''@ ftp.my.com/x.txt"> ';?>
Or, if you want to pass the information through the PATH_INFO component of the URL:
Example 2. rawurlencode () Example 2
The code is as follows:
Echo 'rawurlencode ('sales and marketing/Miami '),' "> ';?>
During decoding, you can use the co

We need to create a variable to hold we decode the JSON data and then calljson.Unmarshal方法,并把需要解码的数据和这个变量的指针,传递给该函数。
We must first create a place where the decoded data would be Stored,and call json.Unmarshal passing it a of []byte JSON data and a P Ointer tom
err := json.Unmarshal(b, m)
If B contains a valid JSON data and the structure matches m, then err will return nil, and the decoded
the plus sign ('+') as a space, while urldecode () can. The following is a detailed example: String urldecode (string str) Decodes any % # in the encoded string ##. Returns the decoded string.
Example 1. urldecode () example
$ A = explode ('', $ QUERY_STRING );$ I = 0;While ($ I $ B = split ('=', $ a [$ I]);Echo 'Value for parameter ', htmlspecialchars (urldecod

Here, the deflate function implements LZ compression, while inflate implements decompression.First, we use a small PL/SQL code to test the structure of the encrypted string. Here I will talk about
time you read four bytes from the input bytebuf, decode it into an int variable, and then add the decoded int variable to the list, and when no more objects are added to the list, Then the contents of the list will be sent to the next channelinboundhandler.The following code listing shows the code for the TointegerdecoderAlthough Bytetomessagedecoder can make this conversion mode very simple, you may find that every time you need to verify that there
}, Error:function(XMLHttpRequest, Textstatus, Errorthrown) {//Todo Failed method } })Background:QueryString This function is automatically decoded, so there is no need to write any decoded statements.It is also important to note that:
Escape () does not encode "+". But we know that when we submit a form, the page will be converted to a + character if there are any spaces.
, Urldecode () and rawurldecode () decoded strings are encoded in UTF-8 format, if the URL contains Chinese, and the page setting is not a UTF-8, the decoded string must be converted before it can be properly displayed.

This is a native Python serialization method. However, JSON has become popular in recent years, and Python has added support for it. Now you can use JSON for codec.Copy codeThe Code is as follows:Import json
Variable = ['hello', 42, [1, 'two'], 'apple']Print "Original {0}-{1}". format (variable, type (variable ))
# EncodingEncode = json. dumps (variable)Print "Encoded {0}-{1}". format (encode, type (enco
result is:
DATA: [{'A': 'A', 'C': 3.0, 'B' :( 2, 4)}] # python dict DATA is JSON Without sequential storage: [{"a": "A", "c": 3.0, "B": [2, 4]}]
Decoding
Decodingjson.loads()Function to convert the json format to dict.
Import jsondata = '{"a": "A", "B": [2, 4], "c": 3.0}' # json format decoded = json. loads (data) print "DECODED:", decoded
The output result is
On the JSP garbled problem resolution.1 The most basic garbled problem.This garbled problem is the simplest garbled problem. General Xinhui appears. is the page encoding inconsistency caused by garbled.I'm a good man. Three places of code.The first place in the encoding format is the storage format of the JSP file. Eclipse will save the file based on this encoded format. and compile the JSP file, including the Chinese characters inside.The second encoding is the decoding format. Because the file

cacheThe bitmap cache stores AndroidBitmapObjects. These are fully decoded images ready for display or postprocessing.On Android 4.x and lower, the bitmap cache's data lives in the ashmem heap, not in the Java heap. this means that images don't force extra runs of the garbage collector, slowing down your app.Android 5.0 has much improved memory management than earlier versions, so it is safer to leave the bitmap cache on the Java heap.When your app i
