get 请求示例

// Create a Resty Client
client := resty.New()

resp, err := client.R().
    EnableTrace().
    Get("https://httpbin.org/get")

// Explore response object
fmt.Println("Response Info:")
fmt.Println("  Error      :", err)
fmt.Println("  Status Code:", resp.StatusCode())
fmt.Println("  Status     :", resp.Status())
fmt.Println("  Proto      :", resp.Proto())
fmt.Println("  Time       :", resp.Time())
fmt.Println("  Received At:", resp.ReceivedAt())
fmt.Println("  Body       :\n", resp)
fmt.Println()

// Explore trace info
fmt.Println("Request Trace Info:")
ti := resp.Request.TraceInfo()
fmt.Println("  DNSLookup     :", ti.DNSLookup)
fmt.Println("  ConnTime      :", ti.ConnTime)
fmt.Println("  TCPConnTime   :", ti.TCPConnTime)
fmt.Println("  TLSHandshake  :", ti.TLSHandshake)
fmt.Println("  ServerTime    :", ti.ServerTime)
fmt.Println("  ResponseTime  :", ti.ResponseTime)
fmt.Println("  TotalTime     :", ti.TotalTime)
fmt.Println("  IsConnReused  :", ti.IsConnReused)
fmt.Println("  IsConnWasIdle :", ti.IsConnWasIdle)
fmt.Println("  ConnIdleTime  :", ti.ConnIdleTime)
fmt.Println("  RequestAttempt:", ti.RequestAttempt)
fmt.Println("  RemoteAddr    :", ti.RemoteAddr.String())
