Golang Parsing HTML files

Because JSON is needed in the project, Https://github.com/bitly/go-simplejson.git is used

Download to the configuration of the &gopath path under SRC

The address of the connection is:

"Http://lengxiaohua.com/lengxiaohuaapi/joke?action=getJokes&interval=weekly&sort=popular&type=text %7cimage&start=0&limit=20 "

The steps are simple.

1. Connect URL to get page content

2. Convert page content to JSON

3. Parse JSON, print to console

The code is simple as follows, and it can be run directly

</pre><pre name= "code" class= "CPP" >//Testgocommand project Main.gopackage mainimport ("Encoding/json" " FMT "Go-simplejson"//For JSON get//"gopkg.in/mgo.v2"//"Gopkg.in/mgo.v2/bson" "Io/ioutil" "net/http"//"regexp"//" StrConv ") Func Get (URL string) (content string, StatusCode int) {resp, err1: = http. Get (URL) if err1! = Nil {StatusCode = -100return}defer resp. Body.close () data, err2: = Ioutil. ReadAll (resp. Body) if err2! = Nil {StatusCode = -200return}js, err: = Simplejson.

Print (weilist) StatusCode = resp. Statuscodecontent = return}/**interface coercion type conversion **/func Prase (M1 interface{}) (Wei Weidata) {var dat map[ String]interface{}dat = M1. (map[string]interface{}) Wei = weidata{dat["uri"]. ( string), dat["user_name"]. (string), dat["content". (string), String (dat["Jokeid"]. ( Json. Number))}fmt. Println ("", Wei) return}type weidata struct {URL stringtitle stringcontent stringkey string}func Main () {FMT. PRINTLN (' Get index ... ') _, StatusCode: = Get ("http://lengxiaohua.com/lengxiaohuaapi/joke?action=getjokes& Interval=weekly&sort=popular&type=text%7cimage&start=0&limit=20 ") if statusCode! = + (Return}}

Operation Result:
