我正在尝试在我的 go 应用程序上使用 awx xray 来对服务进行 http 调用。我只是跟着这个,不确定我是否错过了什么,https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-go-httpclients.html
我像这样进行http调用:
payloadStr, _ := json.Marshal(dxPayload)
fmt.Println("size: ", int(unsafe.Sizeof(bytes.NewBuffer(payloadStr))))
clambda = &http.Client{}
//-------ADDED XRAY HERE-------//
xray.Client(clambda)
reqLambda, errReq := http.NewRequest("POST", lambdaurl, bytes.NewBuffer(payloadStr))
if errReq != nil {
log.Fatal("Request Error: ", errReq)
return
}
reqLambda.Header.Add("accept", "application/json;v=1")
reqLambda.Header.Add("cach-control", "no-cache")
reqLambda.Header.Add("content-type", "application/json")
reqLambda.Header.Add("authorization", "Bearer " + devexToken.AccessToken)
respLambda, errResp := clambda.Do(reqLambda)
if errResp != nil {
log.Fatal("Status Response Error ", errResp)
return
} else {
}
在我的main.go
文件中,我有这个func init()
func init() {
pConfig = createpConfig()
//aws xray config
ss, err := sampling.NewLocalizedStrategyFromFilePath("xray.json")
if err != nil {
panic(err)
}
xray.Configure(xray.Config{
SamplingStrategy: ss,
})
}
我的xray.json
配置如下所示:
{
"version": 1,
"rules": [
{
"description": "ehb",
"service_name": "ehb-kafka-push",
"http_method": "*",
"url_path": "/private/api/calllambda/*",
"fixed_target": 0,
"rate": 0.85
}
],
"default": {
"fixed_target": 1,
"rate": 0.1
}
}
现在,当我启动我的应用程序时......我的 api 调用正在通过,但我在 AWS xray 和本地的 xray 守护程序中看不到任何东西,我只在日志中看到:

我在这里想念什么?除了 X 射线部分,一切似乎都正常工作,为什么我没有收到任何数据或错误?
