ObjectiveAfter the request is sent on the network, it is often judged by the request's status code that the successful failure or not, the common status code is 200,404,500.But do you think there are only so many status codes for HTTP requests? is actually much more than this.Let's take a look at the status codes commonly used in HTTP requests today in this article.HTTP status Code2xx-Request succeededThe s

BCD code is often used in PLC Data conversion. What is BCD code and compressed BCD code? What is the difference between the two? In a digital system, all kinds of data must be converted to binary code for processing. People are used to using decimal numbers. Therefore, the input and output of the digital system still use decimal numbers, in this way, a four-digit binary number is used to represent a single-digit decimal number. The binary code used to represent a decimal number is called binary

In 1953, David A. Huffman published his paper "A Method for the construction of Minimum-redundancy Codes", and hence print Ed his name in the history of computer science. as a professor who gives the final exam problem on Huffman codes, I Am encountering a big problem:the Huffman codes is not unique. for example, given a string "Aaaxuaxz", we can obse Rve that th

This article describes how to use PHP to crack the website verification code. For more information, see the verification code function. it is generally set to prevent malicious registration, brute force cracking, or batch posting. The so-called verification code is to generate an image with a string of randomly generated numbers or symbols, and add some interference pixels to the image (preventing OCR). The user can identify the verification code information with the naked eye, enter a form to s

In the 3rd chapter of the HTTP authoritative guide, when explaining the 30X status code, it is not clear why there should be 302, 303, 307, and their relationship, a "problem in HTTP/1/1" Let me confused, inexplicably, and the fifth chapter in the redirect response, did not say that now very common 302 , instead of 303 and 307 that I've never met. Very confusing, for these 3 status codes, Wiki and RFC documents are detailed, the following I think in m
