This article mainly introduces how golang realizes http request weather, the introduction in the article is very detailed, has certain reference value, interested friends must read it!

I. Preparation:

1. Register a developer account and apply for a key

2, golang development tools LiteIDE (can be Baidu).

Or www.jb51.net/softjc/119086.html

3. Understand the basic grammar of golang.

Second, direct code

Because the code comments are very detailed, so directly on the code.

package mainimport ( "fmt" "io/ioutil" "net/http")func main() { rlt, err := doHttpGetRequest("https://restapi.amap.com/v3/weather/weatherInfo? key= Your Gaode key&city=110101") if err != nil { fmt.Println("net req error") } else { fmt.Println(rlt) }}//custom http get request function//input parameter: request url//return value: rlt, weather data. err, error message//network request func doHttpGetRequest(url string) (rlt string, err error) { // http.Get in net/http, so import "net/http" resp, err := http.Get(url) if err != nil { return "", err } else { //Use efer resp.Body.Close(). When doHttpGetRequest returns successfully, execute this line of statements. More for handle closure defer resp.Body.Close() // io Stream data read. Need to quote io/ioutil body, err := ioutil.ReadAll(resp.Body) if err != nil { return "", err } else { return string(body), err } }}

Note: My Gaode key: d2315f3b0b4e57bbf5428e755a73e692. For testing purposes
