Spring cloud builds the microservice architecture GateWay (API GateWay), springcloud Preface As mentioned in our previous blog, when service A needs to call service B, it only needs to obtain the registered instance of Service B from Eureka and then use Feign to call service B, ribbon is used to achieve load balancing. However, when we expose multiple services to the client at the same time, how does the cl

I. Table Data Gateway) The table data entry provides all the SQL statements used to access a single table or view (including join table queries). Generally, a table is a class. Other code uses it to achieve database interaction. Based on this feature, the table data entry is well integrated with the transaction script code and the table module. During query, the table data interface can return the dataset, DTO, or DTO list. The form of DTO and DTO is

Description1, NetworkManager tool is the Ubuntu desktop version of the GUI setup tool.2, this tool is recommended to operate directly on the GUI, it is not recommended to use the command line management, such as WiFi configuration.3, of course, this tool can have command line tools:nmcli, if the use of NetworkManager to configure the network, then IP, gateway, DNS can be queried through this tool.4, if the command line network settings are configured,

introduce A server (not necessarily a WEB server) is being used as a gateway or proxy to fulfill a request from a customer (such as your browser or our Checkupdown robot) to access the desired URL. To complete the request, this server accesses an upstream server but receives an invalid response. This usually does not mean that the upstream server is closed (no response to the gateway/proxy), but that the up

Recently, the phenomenon of server downtime more frequent, temporary work, G to hang up, 502 Bad Gateway Nginx, I can not help but remind me before the 504 gateway time-out, the two should be a bit of contact, we must find out. The implication of Nginx 504 Gateway time-out is that the requested gateway is not requested

Centos/linux How to view the gateway address/gateway address? There are many commands to view the gateway under Linux, but if the IP is obtained by DHCP, then some commands are not applicable, and there are also common query gateway commands.1.ifconfig-a and cat/etc/resolv.conf (main view ip/netmask and DNS)2.netstat-r

Problem descriptionThe troubleshooting steps in How to troubleshoot an application gateway that returns HTTP Code 502 or the client gets slow response from the application Gateway (a) can be judged as a response exception due to a WEB server's own problem.You can then turn on failed request tracing (the FRT McCartney) feature in IIS to track and analyze the cause of this response exception.The specific step

Session 1 ARP Proxy technology1. ARP ProxyThe ARP proxy feature is the L3 layer gateway device for all functions, routers or L3 layer switches. The ARP proxy function uses the ARP protocol's unreliability to replace the terminal to carry on the L3 layer forwarding, because Arp-requst broadcast is L3 layer isolation, therefore needs L3 layer gateway to replace the terminal to carry on the Arp-requst, when th

packets will be handed over to the default gateway for processing, this will inevitably increase the burden on the default gateway, resulting in reduced network efficiency. Therefore, the subnet mask should be set based on the network size. If a network has no more than 254 computers, you can use "255.255.255.0" as the subnet mask. Currently, most local networks will not exceed this number, therefore, "255

What is a gatewayThe term gateway is derived from the definition of the computer network, the gateway is also called the Inter-Network connector, protocol converter. The exact definition of a gateway is a connection between two computer programs or systems, and the gateway acts as a portal between two programs, allowin

Softswitch is a key technology for implementing next-generation networks. Media Gateway controller is a device that uses Softswitch technology to implement call control. This article mainly introduces the function and system structure of the Media Gateway controller, and discusses a solution for evolution from a circuit switch to a media gateway controller. I. So

can vary over time. Instances of the service or host+ ports may change dynamically. There are also several possible UI requirements for the front-end: Coarse-grained APIs, and microservices typically provide a fine-grained API, which is a big problem for the UI if you want to call a fine-grained API many times. Different client devices may require different data. Web,h5,app The network performance of different devices, for multiple APIs, this access needs to transfer t

A gateway is a computer system or device that acts as a conversion task. The gateway is a translator between two systems that use different communication protocols, data formats, languages, and even completely different architectures. Unlike the Net Bridge, the gateway repacks the received information to meet the needs of the target system. The
