Common methods of 1,http
Get gets the specified resource
POST 2M submits data to the specified resource for processing requests, and is used in the restful style for the new resource head to get the specified resource header information
Put replace specified resource (no browser action is supported)
Delete Deletes the specified resource
2, configure the server's put request mode:
Copy Code code as follows:
1>
N Open Terminal
P Cd/etc/apache2
P sudo vim httpd.conf
N Enter in vim
P/httpd-dav.conf
• Find httpd-dav.conf
P Press 0 to move the cursor to the beginning of the line p press X to remove the beginning of the line
P Input: Wq, save and exit
2>
Continue typing at terminal
Cd/etc/apache2/extra
sudo vim httpd-dav.conf
In Vim, change the digest of the first red position in the right figure to basic
Input: Wq, save and exit
Tips:
Modify the way that the user authorizes
The second red Spot is the file that holds the user's password (/USER/USER.PASSWD)
The third red position is the user name (Admin) that is able to use the put request
4>
In the terminal input P CD/USR
sudo htpasswd-c/usr/user.passwd admin
Ls-l
sudo chgrp www/usr/user.passwd
Ls-l
5>
Create the Var folder, save davlockdb related files n sudo mkdir-p/usr/var
sudo chown-r Www:www/usr/var
Build Upload folder: Uploads
sudo mkdir-p/usr/uploads
sudo chown-r www:www/usr/uploads
Restart Apache
sudo apachectl-k restart

The schematic diagram of the modified Ls-l view is as follows
If you can see these three, it means the configuration is correct.

Copy Code code as follows:
#import "KUViewController.h"
#import "KUProgress.h"
@interfaceKUViewController () <NSURLSessionTaskDelegate>
Download the progress class, Inherit UIView
@property (Weak, nonatomic) Iboutlet kuprogress *progressview;
@end
