今天遇到几个PUT上传的点,但是都没利用起来。一怒之下,在自己本地试了一下。步骤如下:
一、环境:
首先,根据 配置Apache服务器支持向目录PUT文件 更新一下httpd.conf文件,重启所有服务。
二、HTTP - PUT
PUT的前提,是了解HTTP协议。下面给出HTTP - PUT的一个模板:
PUT /test.txt HTTP/1.1
Accept: */*
Accept-Language: en-US
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32)
Host: test.com:8080hello world
要注意如下几个点:
① PUT方法是HTTP 1.1协议中才出现的。
② HTTP协议对空格敏感,每行数据的结尾不能出现空格
③ HTTP头部和数据中间要空一行,即HTTP头部是以\r\n\r\n结尾的。
④ 端口号直接跟在HOST后面
三、第一次PUT
好了,现在可以PUT了。用Linux下的nc命令来进行连接。
nc -v www.baidu.com 80
root@bb:/etc# nc -v 192.168.163.1 8080 nc: 192.168.163.1 (192.168.163.1) 8080 [http-alt] open
/*在得到如上输出之后,再将PUT包的内容贴到命令行中,回车*/ PUT /test.txt HTTP/1.1 Content-Length: 11 Accept-Language: en-US User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32) Host: 192.168.163.1:8080hello world
/*发送的PUT包到此为止,以下为收到的数据包*/ HTTP/1.1 500 Internal Server Error Date: Wed, 29 Apr 2015 09:15:18 GMT Server: Apache/2.2.21 (Win64) PHP/5.3.10 DAV/2 Content-Length: 535 Connection: close Content-Type: text/html; charset=iso-8859-1<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>500 Internal Server Error</title> </head><body> <h1>Internal Server Error</h1> <p>The server encountered an internal error or misconfiguration and was unable to complete your request.</p> <p>Please contact the server administrator, admin@localhost and inform them of the time the error occurred,and anything you might have done that may have caused the error.</p> <p>More information about this error may be available in the server error log.</p> </body></html>
好像不对啊,500是服务器内部错误啊。好吧好吧,我们去看看主机的Apache日志。
四、再次配环境
主机用的是WAMP,日志在/wamp/logs/apache_error.log。找到对应的那一条:
通过浏览器搜索,又找到一篇日志。Linux(CentOS) 服务端搭建与配置,原来用HTTP - PUT还要添加一个什么锁。
所以解决方法是:在Apache配置文件中,也就是httpd.conf,增加一行,设定webDAV锁位置。再次重启所有服务。
DavLockDB DavLock #目录没有就创建(DavLock 为文件名,应该有的目录结构是\wamp\bin\apache\Apache2.2.21\DavLock)
五、终于成功PUT
root@bb:/etc# nc -v 192.168.163.1 8080 nc: 192.168.163.1 (192.168.163.1) 8080 [http-alt] open PUT /test.txt HTTP/1.1 Content-Length: 11 Accept-Language: en-US User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Win32) Host: 192.168.163.1:8080hello world HTTP/1.1 201 Created Date: Wed, 29 Apr 2015 09:25:24 GMT Server: Apache/2.2.21 (Win64) PHP/5.3.10 DAV/2 Location: http://192.168.163.1:8080/test.txt Content-Length: 181 Content-Type: text/html; charset=ISO-8859-1<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>201 Created</title> </head><body> <h1>Created</h1> <p>Resource /test.txt has been created.</p> </body></html>
