In addition to creation, comparison, and other methods, nsstring can also extract a character segment from the parent string to form a new substring. There are three methods used: Substringtoindex:If I enter 6 after this method, it means to intercept the first to sixth characters and form a new substring, similar to an open interval, (0 Substringfromindex:If I enter 5 after this method, it means to intercept the string from the fifth to the last one and form a new substring, similar to

URL. 302 Found Similar to 301, but the new URL should be treated as a temporary alternative, rather than permanent. Note that the status information corresponding to HTTP1.0 is "Moved Temporatily ". When this status code appears, the browser can automatically access the new URL, so it is a very useful status code. Note that this status code can be replaced with 301 sometimes. For example, if the browser mistakenly requests http: // host /~ If the user (with a slash missing), some

Note: Although the RFC 1945 and RFC 2068 specifications do not allow the client to change the method of the request during redirection, many existing browsers treat the 302 response as a

301, but the new URL should be treated as a temporary replacement instead of permanent. Note that the corresponding status information in HTTP1.0 is "Moved temporatily". When the status code appears, the browser can automatically access the new URL, so it is a useful status code. Note that this status code can sometimes be used with 301 substitutions. For example, if the browser mistakenly requests Http://host/~user (the trailing slash is missing), some servers return 301, and some return 302.
