Code Snippets-golang implement a simple Web server

------------------------------the following piece of code to implement the simplest Web Server: compiled environment: Linux Mint Cinnamon 64-bit Golang 1.7------------------- -----------//main.gopackage mainimport ("fmt" "log" "net/http")//processing home page request Func index (w HTTP. responsewriter, R *HTTP. Request) {//writes The content to the client Fmt. fprintf (w, "Hello world!")} Func main () {http. Handlefunc ("/", index)//set access to the route err: = Http. Listenandserve (": 9090", Nil)//set The listening port if err! = Nil {log. Fatal ("listenandserve:", Err)}}------------------------------after Executing the above program, open the Web browser and enter in the address Bar: 127.0.0.1:9090 You will be able to access this server.　　It only implements the simplest single-page Output.　　Next we have the server accept the data entered by the client and then feed it back to the Client. first, We write a form page to the client so that the client has a place to fill in the data and submit the Data. You will then need to add a page handler function on the server to handle the data submitted by the User. The following is the beginning of the implementation of this Feature. ------------------------------//main.gopackage mainimport ("fmt" "log" "net/http")//write This data to the client so that the client can fill in the text and commit Var indexhtml = '
