从 JSON 文件中读取数据并将其作为发布请求发送

Question

如何从 json 文件中读取数据并将其作为发布请求发送到 uri 终结点。我目前正在学习Go语言，并从事我的第一个学习项目。这是我的示例数据// parent.json{"name":"Jade Copnell","age":16,"gender":"Agender","occupation":"Account Representative II","numbers":"178-862-5967","children":{"name":"Kayne Belsham","age":38,"gender":"Genderqueer","occupation":"Clinical Specialist","interest":"Re-engineered discrete methodology","number":"145-355-4123"},"friends":{"name":"Stephi Aries","age":74,"gender":"Genderqueer","occupation":"Senior Sales Associate","numbers":"873-726-1453","interests":"Self-enabling systematic function","methow":"24/7"}}这就是我写的，当我运行下面的脚本时，我倾向于得到一个类似于下面的数据作为输出，我也得到发送到数据库的空数据。"{\"name\":\"Jade Copnell\",\"age\":16,\"gender\":\"Agender\",\"occupation\":\"Account Representative II\",\"numbers\":\"178-862-5967\",\"children\":{\"name\":\"Kayne Belsham\",\"age\":38,\"gender\":\"Genderqueer\",\"occupation\":\"Clinical Specialist\",\"interest\":\"Re-engineered discrete methodology\",\"number\":\"145-355-4123\"},\"friends\":{\"name\":\"Stephi Aries\",\"age\":74,\"gender\":\"Genderqueer\",\"occupation\":\"Senior Sales Associate\",\"numbers\":\"873-726-1453\",\"interests\":\"Self-enabling systematic function\",\"methow\":\"24/7\"}}"func main() {    // Open the file.    f, _ := os.Open("./go_data/parent.json")    // Create a new Scanner for the file.    scanner := bufio.NewScanner(f)    // Loop over all lines in the file and print them.    for scanner.Scan() {        responseBody := scanner.Text()        postBody, _ := json.Marshal(responseBody)        //fmt.Println(postBody)        time.Sleep(2 * time.Second)        webBody := bytes.NewBuffer(postBody)        // fmt.Println(webBody)        resp, err := http.Post("http://127.0.0.1:5000/v1/parent", "application/json", webBody)        if err != nil {            log.Fatalf("An Error Occured %v", err)        }        time.Sleep(2 * time.Second)        defer resp.Body.Close()    }}

如果您改为这样做，该怎么办？第三个参数到 http。帖子是一个io。读取器接口 - 您的文件“f”实现。

package main

import (

    "bufio"

    "log"

    "net/http"

    "os"

    "time"

)

func main() {

    // Open the file.

    f, _ := os.Open("./go_data/parent.json")

    resp, err := http.Post("http://127.0.0.1:5000/v1/parent", "application/json", f)

    if err != nil {

        log.Fatalf("An Error Occured %v", err)

    }

    time.Sleep(2 * time.Second)

    defer resp.Body.Close()

}
