CentOS修改IP地址 # ifconfig eth0 192.168.1.80 这样就把IP地址修改为192.168.1.80(如果发现上不了网了，那么你可能需要把网关和DNS也改一下，后面会提到)，但是当你重新启动系统或网卡之后，还是会变回原来的地址，这种修改方式只适用于需要临时做IP修改。要想永久性修改，就要修改/etc/sysconfig/network-scripts/ifcfg-eth0这个文件，这个文件的主要内容如下（你的文件中没有的项，你可以手动添加）： # vi /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 #描述网卡对应的设备别名 BOOTPROTO=static #设置网卡获得ip地址的方式，选项可以为为static，dhcp或bootp BROADCAST=192.168.44.255 #对应的子网广播地址 HWADDR="00:0C:29:6B:2E:7B"#对应的网卡物理地址 IPADDR=192.168.44.137 #只有网卡设置成static时，才需要此字段 NETMASK=255.255.255.0 #网卡对应的网络掩码 NETWORK=192.168.44.0 #网卡对应的网络地址，也就是所属的网段 ONBOOT=yes #系统启动时是否设置此网络接口，设置为yes时，系统启动时激活此设备 CentOS修改网关 # route add default gw 192.168.1.1 dev eth0 这样就把网关修改为192.168.1.1了，这种修改只是临时的，当你重新启动系统或网卡之后，还是会变回原来的网关。要想永久性修改，就要修改/etc/sysconfig/network 这个文件，这个文件的主要内容如下（你的文件中没有的项，你可以手动添加）： # vi /etc/sysconfig/network NETWORKING=yes #表示系统是否使用网络，一般设置为yes。如果设为no，则不能使用网络。 HOSTNAME=centos #设置本机的主机名，这里设置的主机名要和/etc/hosts中设置的主机名对应 GATEWAY=192.168.1.1 #设置本机连接的网关的IP地址。 **********上面的文件修改完要重新启动一下网卡才会生效：# service network restart ******** CentOS修改DNS 上面的都修改完之后，当你ping一个域名是肯能不通，但ping对应的IP地址是同的，这时我们需要修改一下DNS。修改DNS要通过修改/etc/resolv.conf这个文件： # vi /etc/resolv.conf nameserver 8.8.8.8 #google域名服务器 nameserver 8.8.4.4 #google域名服务器 通过上面的所有设置，系统应该可以上网了。 如果centos系统建立在虚拟机之上，那么在设置虚拟机的网络时请选择‘网桥适配器’连接。 from:https://www.cnblogs.com/liuys635/p/11335594.html

View Details通过 Opw.HttpExceptions.AspNetCore 搞定了。 1）安装 nuget 包 Opw.HttpExceptions.AspNetCore
|
1 |
<PackageReference Include="Opw.HttpExceptions.AspNetCore" Version="2.3.0" /> |
2）Startup.ConfigureServices 中添加 AddHttpExceptions
|
1 |
services.AddControllers().AddHttpExceptions(); |
3）Startup.Configure 中添加 UseHttpExceptions
|
1 |
app.UseHttpExceptions(); |
