孤者浪人 提交于 2020-01-07 13:37:02
Nginx强制http跳转https访问有以下几个方法 nginx的rewrite方法 可以把所有的HTTP请求通过rewrite重写到HTTPS上 配置 方法一: server{ listen 80; server_name XXXXX.com; #你的域名 rewrite ^(.*)$ https://XXXXXX.com permanent; location ~ / { index index.html index.php index.htm; } } 方法二: server{ listen 80; server_name XXXXX.com; #你的域名 return 301 https://$server_name$request_uri; location ~ / { index index.html index.php index.htm; } } 方法三: server{ listen 80; server_name XXXXX.com; ##你的域名 rewrite ^(.*)$ https://$host$1 permanent; location ~ / { index index.html index.php index.htm; } } nginx的497状态码 497 – normal request was sent to HTTPS

Nginx核心配置详解

1 全局配置 user nginx nginx; # 启动nginx工作进程的用户和组,默认为nobody worker_processes auto; # 启动nginx工作进程的数量,默认为1 worker_cpu_affinity 0001 0010 0100 1000; #将Nginx⼯作进程绑定到指定的CPU核⼼,默认Nginx是不进⾏进程绑定的,绑定并不是意味着当前nginx进程独占⼀核⼼CPU,但是可以保证此进程不会运⾏在其他核⼼上,这就极⼤减少了nginx的⼯作进程在不同的cpu核⼼上的来回跳转,减少了CPU对进程的资源分配与回收以及内存管理等,因此可以有效的提升nginx服务器的性能,也可以设置为auto。 可以执行以下命令观察工作进程是否一致运行在同一核CPU上 [root@CentOS7-01 ~]#watch -n1 'ps axo pid,cmd,psr,user | grep nginx|grep -v grep' #错误⽇志记录配置,语法:error_log file [debug | info | notice | warn | error | crit | alert | emerg] #error_log logs/error.log; #error_log logs/error.log notice; error_log logs/error

问题 Xcode says that PHAsset doesn't have the 'location' member. What's the remedy for Swift? 回答1: Short answer: you might have forgotten to import CoreLocation; import Photos import CoreLocation let asset: AnyObject? = nil if let asset = asset as? PHAsset { let location = asset.location } When I remove the CoreLocation import, I can replicate your error. 来源: https://stackoverflow.com/questions/30249163/how-to-i-extract-a-phassets-location-property

和自甴很熟 提交于 2020-01-06 12:43:25
问题 My android application function is to track the user location when it walk/run or when he never moves(then location should not change)First, the location is inaccurate and red marker keeps popping out on the map even if i never move. the position where it pops out is also inaccurate. For those who did similar location tracking app before, the blue dot should be the same place as the latest red marker right? but my blue dot is always away most of the time. red marker shows a more accurate
