How to call a https request by use DispatchHttpCall

This is my code:

cluster := "outbound|443||httpbin.org"
headers := [][2]string{
    {":scheme", "https"},
    {":method", "GET"},
    {":path", "/get"},
    {":authority", "httpbin.org"},
    {"accept", "*/*"},
}
data, err := proxywasm.DispatchHttpCall(
    cluster,
    headers,
    nil,
    nil,
    1000,
    func(numHeaders, bodySize, numTrailers int) {
	    resp, _ := proxywasm.GetHttpCallResponseBody(0, 10000)
	    r := string(resp)
	    proxywasm.LogCriticalf("response: %v", r)
	    proxywasm.ResumeHttpRequest()
    })
