This article mainly explains "how to deal with HTTP 302 in Linux curl command". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn how to deal with HTTP 302 in the Linux curl command.

When using the curl command on a Linux system, you occasionally encounter some URL jumping to the new URL, that is, 3XX in HTTP (redirection, redirection, such as HTTP 302).

$curl-s-I $URL > log

At this point, in the returned message, there is a Location field indicating the new URL.

$cat log HTTP/1.1 302 Found Expires:-1 Cache-Control: private, max-age=0Pragma: no-cache Location: http://182.118.2.11/youku/557186***52945820CFCE162719/03000811074CDDB614769602996C24421AE8D8-C2A3-1BD9-74AC-F5B071A94E33.MP4 Content-type: text/html Connection: close Date: Tue, 0***pr 2011 08:37:07 GMT Server: F_LIGHTY_TJ8

When I try to get this new URL and then curl it, I always report HTTP 400 (Bad Request, wrong request).

$URL= `cat log | grep'^ Location' | cut-f2-d '`$curl-s-I $URL > log $cat log HTTP/1.1 400 Bad RequestContent-Type: text/html Content-Length: 349 Connection: close Date: Tue, 0***pr 2011 08:32:04 GMT Server: YOUKU.ZZ

Print the new URL directly, copy and paste it, and then curl it, but there's no problem.

Curl-s-I http://182.118.2.11/youku/557186***52945820CFCE162719/03000811074CDDB614769602996C24421AE8D8-C2A3-1BD9-74AC-F5B071A94E33.MP4 HTTP/1.1 200 OK Content-Type: video/MP4 Accept-Ranges: bytes ETag: "392853628" Last-Modified: Fri, 12 Nov 2010 21:48:23 GMT Content-Length: 19971197 Connection: close Date: Tue, 0***pr 2011 08:41:18 GMT Server: YOUKU.ZZ

I don't understand!

***. It is found that the new $URL is not exactly the same as "http://182.118.2.11/youku/557186***52945820CFCE162719/03000811074CDDB614769602996C24421AE8D8-C2A3-1BD9-74AC-F5B071A94E33.MP4"," with an extra'0A 'line break at the end of $URl.
