我想要使用HTTP協議獲取OrientDb
數據庫的列表。但我無法得到預期的迴應,我可以在瀏覽器中獲得。列表使用HTTP協議和golang的OrientDb數據庫
如果我在瀏覽器地址欄中輸入http://localhost:2480/listDatabases
然後我有 響應:
{"@type":"d","@version":0,"databases":["MaximDB","GratefulDeadConcerts"],"@fieldTypes":"databases=e"}
?我怎樣才能使用golang
一樣嗎?
我的代碼:
package main
import (
"encoding/json"
"fmt"
"net/http"
)
func main() {
client := &http.Client{}
req, err := http.NewRequest("GET", "http://localhost:2480/listDatabases", nil)
req.SetBasicAuth("root", "1")
resp, err := client.Do(req)
if err != nil {
fmt.Printf("Error : %s", err)
}
fmt.Println("resp")
fmt.Println(ToJson(resp))
}
func ToJson(obj interface{}) string {
b, err := json.MarshalIndent(&obj, "", " ")
if err != nil {
fmt.Printf("Error : %s", err)
}
strJson := string(b)
return strJson
}
它在輸出控制檯:

雖然您可以嘗試['client.Go'](http://golang.org/pkg/net/http/#Client.Get),但對我來說看起來並不像'go'問題。而不是'client.Do'。服務器日誌中的任何錯誤? –
