按如下所示执行获取 URLresp, err := http.Get(path)事先，我打印了或多或少像这样变量pathhttp://localhost:8080/api/history/resources/count?startedAfter="2021-03-06T15%3A27%3A13.894415787%2B0200"当我点击链接时，它确实返回并得到有效的响应。200json但是，代码本身会失败并打印：<!doctype html><html><head><title>HTTP Status 400 – Bad Request</title>Invalid character found in the request target [/api/history/resources/count?startedAfter="2021-03-06T15%3A27%3A13.894415787%2B0200"].

查询参数中的引号似乎导致服务器出现错误。试试这样的东西
apiURL := "http://localhost:8080/api/history/resources/count"
req, err := http.NewRequest("GET", apiURL, nil)
if err != nil {
log.Fatal(err)
}
apiParams := req.URL.Query()
apiParams.Add("startedAfter", "2021-03-06T15:27:13.894415787+0200")
req.URL.RawQuery = apiParams.Encode()
res, err := http.DefaultClient.Do(req)
尝试并还原。
