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

Enter, press enter, and switch the input focus. The implementation idea is compatible with the codes of various browsers. Enter focus During project creation, the customer requires that the input (Focus) can be directly switched using the enter key, and the information can be submitted directly at the last time. The first idea is to copy a piece of code online and use it directly. However, Baidu and Google searched again and found the same code above

Detailed explanation of codes for Python Implementation of HOV and elliptic transformation, and python HOV In polar coordinates, the circle is expressed: X = x0 + rcos θ Y = y0 + rsin θ The center of the circle is (x0, y0), r is the radius, θ is the degree of rotation, and the value range is 0-359. If the center and radius are given, whether the other points are in the circle can be detected. In the image, we take each non-zero pixel as the center poi

Many of the scenarios where node is used for web development may encounter verification codes. Previously, I searched on github and found some class libraries such as node-captcha, they all need to rely on third-party graphics processing libraries or software. When I installed the cario graphics library, it was a great deal of effort, but we actually only used a little small feature of these graphics libraries, you can modify the cropping or productio

Exit and exit Status Codes Exit is used to end a script, just like in C. it also returns a value, which is passed to the parent process of the script. The parent process uses this value for further processing. Each command returns an exit status code (sometimes called return status ). A successful command returns 0, but an unsuccessful command returns a non-zero value. A non-zero value is usually interpreted as an error code. A good UNIX Command, prog
