But there's a problem.
Although JS is very handy for decoding JSON, coding does not seem to be a good idea ...
In the spirit can lazy is lazy, not lazy also as lazy as possible principle, the old dog a bit
It really made me find out.
PHP directly with Json_decode can be decoded, it is very convenient to use
Copy Code code as follows:
function Json_encode_js (AAA) {
Function je (str) {
var a=[],i=0;
var pcs= "abcdefghijklmnop

Specific: You need to learn more about base64 encoding and decoding.

C # base64 decoded binary output
Regarding the pack in PHP, how can the HET hexadecimal stream be decoded? I tried to use PHP for a dht Crawler. because data transmission uses bencode, this is okay and can be correctly decoded. However, if find_node data is sent, there is a nodes in the obtained data, which is a binary stream encoded using the struct structure. according to the dht protocol, it is: 20-byte node id + 4-byte ip address + 2-b

1. Issue backgroundWhen crawling Web Data using URLLIB2 module, if you want to use how to request headers, reduce the amount of data transferred. The returned data is gzip compressed. Directly following Content.decode ("UTF8"), the decoding will be an exception, and the actual encoding type of the Web page data cannot be detected.2. Problem analysisBecause HTTP requests, if the request header contains "accept-encoding": "gzip, deflate", and the Web server side supports, the returned data is comp
When my colleague used prototype. js for Ajax applications, the script always prompts "the decoded URI is not legally encoded" when the GET request contains Chinese parameters, asking me to solve the problem. This issue has something to do with URL encoding. But in the specific debugging process, it still encountered some trouble and took some detour. Fortunately, it was solved smoothly. My colleague tried to pass unencoded Chinese parameters directly
, otherwise, javac will incorrectly encode your file. at this time, the character string of the bytecode file itself is incorrect, and the output is not used;

6.1 The servlet/JSP file encoding must be consistent with the content-type output; otherwise, additional encoding and decoding steps must be added;
6.2, HTTP/POST and encodeURI encoding are passed in UTF-8;

PHP based on Base64 decoded image and encrypted image restore instance,
This paper describes the implementation of PHP based on Base64 decoded image and encrypted image restoration. Share to everyone for your reference. The implementation method is as follows:
In this case, $data is a base64 encoded image. The specific code is as follows:
Copy CodeThe code is as follows: File name: base64.php$data = "/9j/4
This article mainly introduces the methods for restoring php base64-based decoded images and encrypted images, and describes the usage of the base64_decode function as an example, for more information about how to restore encrypted and base64-decoded php images, see the following example. Share it with you for your reference. The specific implementation method is as follows:
In this example, $ data is a ba
When python requests html data using gzip headers, the response content is garbled and cannot be decoded. pythongzip1. Background
When using the urllib2 module to capture web data, if you want to use the request header, you can reduce the amount of data during transmission. The returned data is compressed by gzip. Directly following content. decode ("utf8"), decoding will result in exceptions and the actual encoding type of webpage data cannot be dete
FFmpeg has very powerful features including video capture, video format conversion, video capture, video watermarking, etc. The use of these features on the Internet is mostly based on the command line. This is not conducive to our in-depth study of customized FFmpeg, in the future I will write a series of code to implement these features of the tutorial for everyone to learn. The first part of this series I am going to write on the implementation of Windows, after the partial write porting to A

Coded Triangle NumbersProblem 42The nth term of the sequence of triangle numbers are given by, TN =? n (n+1); So the first ten triangle numbers is:1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...By converting a word to a number corresponding to its alphabetical position and adding these values we form A word value. For example, the word value for SKY is + one + + = = T10. If the word value is a triangle number then we shall call the word a triangle word.Using Words.txt (Right click and ' Save link/targe
, as shown in, The expression for T in the array is the English letter, and the value of the array is the result.Similarly, it is possible to store more tables in memory according to other requirements, to calculate the logical result of the judgment beforehand, and to get the array value directly is the result. Table-driven mode is often used to replace many if-else, switch-case logic judgments, and its use is helpful to improve the readability and maintainability of code. The ASCII table drive
