Read data from a JSON file and send it as a Post request

问题

你好！以下是你提供的代码的翻译：

如何从 JSON 文件中读取数据并将其作为 POST 请求发送到 URI 终点。
我目前正在学习 Go 语言，并且正在进行我的第一个学习项目。

这是我的示例数据：

  1. // parent.json
  3. {"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"}}

这是我编写的代码，当我运行下面的脚本时，我得到的输出数据类似于下面的内容，并且我还会将空数据发送到数据库中：

  1. "{\"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\"}}"
  1. func main() {
  2. 	// 打开文件。
  3. 	f, _ := os.Open("./go_data/parent.json")
  4. 	// 为文件创建一个新的 Scanner。
  5. 	scanner := bufio.NewScanner(f)
  6. 	// 循环遍历文件中的所有行并打印它们。
  7. 	for scanner.Scan() {
  8. 		responseBody := scanner.Text()
  10. 		postBody, _ := json.Marshal(responseBody)
  11. 		//fmt.Println(postBody)
  12. 		time.Sleep(2 * time.Second)
  13. 		webBody := bytes.NewBuffer(postBody)
  14. 		// fmt.Println(webBody)
  16. 		resp, err := http.Post("http://127.0.0.1:5000/v1/parent", "application/json", webBody)
  18. 		if err != nil {
  19. 			log.Fatalf("An Error Occured %v", err)
  20. 		}
  21. 		time.Sleep(2 * time.Second)
  22. 		defer resp.Body.Close()
  23. 	}
  24. }

How can i read data from a json file and send it as a post request to a uri endpoint.
I am currently learning the Go language and working on my first learning project.

This is my sample data

  1. // parent.json
  3. {"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"}}

This is what I have written, when i run the below script, I tend to get a data similar to the below as output and I also get empty data sent to the database.

  1. "{\"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\"}}"
  1. func main() {
  2. 	// Open the file.
  3. 	f, _ := os.Open("./go_data/parent.json")
  4. 	// Create a new Scanner for the file.
  5. 	scanner := bufio.NewScanner(f)
  6. 	// Loop over all lines in the file and print them.
  7. 	for scanner.Scan() {
  8. 		responseBody := scanner.Text()
  10. 		postBody, _ := json.Marshal(responseBody)
  11. 		//fmt.Println(postBody)
  12. 		time.Sleep(2 * time.Second)
  13. 		webBody := bytes.NewBuffer(postBody)
  14. 		// fmt.Println(webBody)
  16. 		resp, err := http.Post("http://127.0.0.1:5000/v1/parent", "application/json", webBody)
  18. 		if err != nil {
  19. 			log.Fatalf("An Error Occured %v", err)
  20. 		}
  21. 		time.Sleep(2 * time.Second)
  22. 		defer resp.Body.Close()
  23. 	}
  24. }

如果你这样做会怎样呢？http.Post的第三个参数是一个io.Reader接口，你的文件"f"实现了这个接口。

  1. package main
  3. import (
  4. 	"bufio"
  5. 	"log"
  6. 	"net/http"
  7. 	"os"
  8. 	"time"
  9. )
  11. func main() {
  12. 	// 打开文件。
  13. 	f, _ := os.Open("./go_data/parent.json")
  15. 	resp, err := http.Post("http://127.0.0.1:5000/v1/parent", "application/json", f)
  17. 	if err != nil {
  18. 		log.Fatalf("发生错误 %v", err)
  19. 	}
  20. 	time.Sleep(2 * time.Second)
  21. 	defer resp.Body.Close()
  22. }
英文:

What if you do this instead. The third argument to http.Post is an io.Reader interface - that your file "f" implements.

  1. package main
  3. import (
  4. 	"bufio"
  5. 	"log"
  6. 	"net/http"
  7. 	"os"
  8. 	"time"
  9. )
  11. func main() {
  12. 	// Open the file.
  13. 	f, _ := os.Open("./go_data/parent.json")
  15. 	resp, err := http.Post("http://127.0.0.1:5000/v1/parent", "application/json", f)
  17. 	if err != nil {
  18. 		log.Fatalf("An Error Occured %v", err)
  19. 	}
  20. 	time.Sleep(2 * time.Second)
  21. 	defer resp.Body.Close()
  22. }
