英文:
Read a post parameter sent through axios in golang
问题
我是你的中文翻译助手，以下是翻译好的内容：
我是Go语言的新手，正在尝试理解这段代码。我遇到了以下问题。
我正在使用axios发送POST请求，代码如下：
const options = {
data: {
test: this.state.value,
},
method: 'POST',
url: `/test`,
};
console.log(options)
axios.request(options).then(
() => {
console.log(this.state.value);
},
(error) => {
console.log(error);
},
);
现在在Go部分，我正在尝试读取它。但是我不知道如何在Go中读取它。我尝试了以下代码，但它不起作用。它只打印出test Value。有人可以帮帮我吗？谢谢。
func routetest(w http.ResponseWriter, r *http.Request) {
test, _ := param.String(r, "test")
fmt.Printf("test Value")
fmt.Printf(test)
fmt.Printf("test Value")
}
更新后的代码
func routeTest(w http.ResponseWriter, r *http.Request) {
type requestBody struct {
test string `json:"test"`
}
body := requestBody{}
decoder := json.NewDecoder(r.Body)
if err := decoder.Decode(&body); err != nil {
// 错误处理
return
}
defer r.Body.Close()
test := body.test
fmt.Printf(test)
}

I am new to golang and try to understand this. I facing the following problem.
I am sending axios post as below
const options = {
data: {
test: this.state.value,
},
method: 'POST',
url: `/test`,
};
console.log(options)
axios.request(options).then(
() => {
console.log(this.state.value);
},
(error) => {
console.log(error);
},
);
And now in the Go part, I am trying to read it. But I am not getting how to read it in Go. I am tried with the following code, but it is not working. It is printing only test Value. Can anyone help me? Thanks.
func routetest(w http.ResponseWriter, r *http.Request) {
test, _ := param.String(r, "test")
fmt.Printf("test Value")
fmt.Printf(test)
fmt.Printf("test Value")
}
Updated Code
func routeTest(w http.ResponseWriter, r *http.Request) {
type requestBody struct {
test string `json:"test"`
}
body := requestBody{}
decoder := json.NewDecoder(r.Body)
if err := decoder.Decode(&body); err != nil {
// some error handling
return
}
defer r.Body.Close()
test := body.test
fmt.Printf(test)
}

最简单的方法是将你的身体解码为类似JSON的结构，然后从中获取你的值。
import (
"encoding/json"
"fmt"
"net/http"
)
type requestBody struct {
Test string `json:"test"`
}
func routeTest(w http.ResponseWriter, r *http.Request) {
body := requestBody{}
decoder := json.NewDecoder(r.Body)
if err := decoder.Decode(&body); err != nil {
// 错误处理
return
}
defer r.Body.Close()
test := body.Test
fmt.Printf(test)
}
英文:
The easiest way is to decode your body to json-like struct and then just get your value from there
import (
"encoding/json"
"fmt"
"net/http"
)
type requestBody struct {
Test string `json:"test"`
}
func routeTest(w http.ResponseWriter, r *http.Request) {
body := requestBody{}
decoder := json.NewDecoder(r.Body)
if err := decoder.Decode(&body); err != nil {
// some error handling
return
}
defer r.Body.Close()
test := body.Test
fmt.Printf(test)
}
