我嘗試通過發出獲取請求從 kibana 服務器獲取 csv 數據。在此服務器向我發送帶有數據的響應后，我編寫csv文件并保存在某個地方。每次 csv 文件都有一行“掛起”。Kibana日志顯示狀態代碼503但是如果我把網址放在瀏覽器中，我可以得到帶有正確數據的csv文件?？赡芪倚枰却鄟碜曰图{的回應。從我的角度來看，問題就在下一個：服務器可以向我發送帶有單行“待處理”的響應，這意味著它需要更多時間來準備正確的響應。我試圖增加客戶時間，但它不起作用client := http.Client{    Timeout: 10 * time.Second,}接下來是帶有go例程和通道/等待組的想法：他們強制Get請求等待獲取正確的數據，而不是“待定”和503狀態代碼import (    "encoding/json"    "errors"    "fmt"    "io/ioutil"    "log"    "net/http"    "sync")type KibanaReportResponse struct {    Path string `json:"path"`}var urlKibanaBase = "http://localhost:5601"var urlKibanaPost = urlKibanaBase + "/api/reporting/generate/csv_searchsource?"var urlParameters = "jobParams=%28browserTimezone%3AEurope%2FBerlin%2Ccolumns%3A%21%28%29%2CobjectType%3Asearch%2CsearchSource%3A%28fields%3A%21%28%28field%3A%27%2A%27%2Cinclude_unmapped%3Atrue%29%29%2Cindex%3Aec074c00-1f62-11ec-8056-8d208a1f6e77%2Cparent%3A%28filter%3A%21%28%29%2Cindex%3Aec074c00-1f62-11ec-8056-8d208a1f6e77%2Cquery%3A%28language%3Akuery%2Cquery%3A%27%27%29%29%2Csort%3A%21%28%28_score%3Adesc%29%29%2CtrackTotalHits%3A%21t%2Cversion%3A%21t%29%2Ctitle%3A%27Discover%20search%20%5B2021-09-27T09%3A19%3A44.977%2B02%3A00%5D%27%29"var urlWithParam = urlKibanaPost + urlParametersfunc main() {    var wg sync.WaitGroup    wg.Add(1)    pathCsvFile := getCsvPathFromKibana(urlWithParam)    go getCsvFile(urlKibanaBase, pathCsvFile, &wg)    defer wg.Wait()}func getCsvPathFromKibana(urlKib string) string {    resKibana := KibanaReportResponse{}    client := &http.Client{}    if req, err := http.NewRequest("POST", urlKib, nil); err != nil {        log.Println("Given a method, URL, andoptional body are wrong", err)    }
