How to upload file using golang code
问题
使用golang代码将文件传输到远程服务,使用其API。他们的要求是请求不能使用multipart/form-data。我尝试了以下curl命令:
curl -i -X PUT -F filedata=@text.txt -H "Content-Type: text/plain" https://url.of.endpoint.com
由于它模拟了表单,所以它不起作用,但是这个命令:
curl -i -X PUT -T text.txt -H "Content-Type: text/plain" https://url.of.endpoint.com
可以正常工作。
我该如何将这个curl命令翻译成golang代码?

curl -i -X PUT -F filedata=@text.txt -H "Content-Type: text/plain" https://url.of.endpoint.com
it doesn't work since it simulates form, but this command:
curl -i -X PUT -T text.txt -H "Content-Type: text/plain" https://url.of.endpoint.com
works perfectly.
How can I translate this curl command to golang code?

你需要创建一个"PUT"请求,并将其请求体设置为文件的内容:
package main
import (
"log"
"net/http"
"os"
)
func main() {
data, err := os.Open("text.txt")
if err != nil {
log.Fatal(err)
}
defer data.Close()
req, err := http.NewRequest("PUT", "http://localhost:8080/test.txt", data)
if err != nil {
log.Fatal(err)
}
req.Header.Set("Content-Type", "text/plain")
client := &http.Client{}
res, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
defer res.Body.Close()
}
请注意,这是一个使用Go语言编写的示例代码,用于创建一个"PUT"请求并将文件内容发送到指定的URL。你需要将代码中的文件路径和URL替换为你自己的值。
英文:
You have to create a "PUT" request and set its request body to the contents of the file:
package main
import (
"log"
"net/http"
"os"
)
func main() {
data, err := os.Open("text.txt")
if err != nil {
log.Fatal(err)
}
defer data.Close()
req, err := http.NewRequest("PUT", "http://localhost:8080/test.txt", data)
if err != nil {
log.Fatal(err)
}
req.Header.Set("Content-Type", "text/plain")
client := &http.Client{}
res, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
defer res.Body.Close()
}

代码如下:
package main
import (
"fmt"
"net/http"
"net/http/httputil"
"os"
)
func main() {
// 打开一个文件。
f, err := os.Open("text.txt")
if err != nil {
panic(err)
}
defer f.Close()
// 将文件发送到指定的URL。
resp, err := http.Post("https://url.of.endpoint.com", "text/plain", f)
if err != nil {
panic(err)
}
defer resp.Body.Close()
// 将响应内容输出以进行调试。
b, err := httputil.DumpResponse(resp, true)
if err != nil {
panic(err)
}
fmt.Println(b)
}
希望对你有帮助!
英文:
It would be like this:
package main
import (
"fmt"
"net/http"
"net/http/httputil"
"os"
)
func main() {
// Open a file.
f, err := os.Open("text.txt")
if err != nil {
panic(err)
}
defer f.Close()
// Post a file to URL.
resp, err := http.Post("https://url.of.endpoint.com", "text/plain", f)
if err != nil {
panic(err)
}
defer resp.Body.Close()
// Dump response to debug.
b, err := httputil.DumpResponse(resp, true)
if err != nil {
panic(err)
}
fmt.Println(b)
}
