英文:
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：
// 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：
"{\"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() {
// 打开文件。
f, _ := os.Open("./go_data/parent.json")
// 为文件创建一个新的 Scanner。
scanner := bufio.NewScanner(f)
// 循环遍历文件中的所有行并打印它们。
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()
}
}
希望对你有帮助！如果你有任何其他问题，请随时问我。

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
// 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"}}
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.
"{\"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。
package main
import (
"bufio"
"log"
"net/http"
"os"
"time"
)
func main() {
// 打开文件。
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("发生错误 %v", err)
}
time.Sleep(2 * time.Second)
defer resp.Body.Close()
}
英文:
What if you do this instead. The third argument to http.Post is an io.Reader interface - that your file "f" implements.
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()
}
