Multipart upload to S3 with custom fields in golang
问题
我是你的中文翻译助手,以下是你提供的代码的翻译:
我是golang的新手,我有以下类似于Python的代码:
package main
import (
"fmt"
"io/ioutil"
"log"
"net/http"
"os"
)
func SendPostRequest(url string, filename string) (string, []byte) {
client := &http.Client{}
data, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
req, err := http.NewRequest("POST", url, data)
req.Header.Set("Content-Type", "multipart/form-data")
if err != nil {
log.Fatal(err)
}
resp, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
content, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Fatal(err)
}
return resp.Status, content
}
func main() {
status, content := SendPostRequest("https://bucket.s3.amazonaws.com/", "what.html")
fmt.Println(status)
fmt.Println(string(content))
}
所以我从S3得到了以下错误:
"您的POST请求的主体不是格式正确的multipart/form-data。"
附注:我已经在S3存储桶策略中给予了完全访问权限,并且我正在尝试在没有任何凭据的情况下上传。稍后我将更新此代码,以便仅在我的VPC中工作。
英文:
I am new to golang , I have python code like below
import requests
url = "https://bucket.s3-us-east-1.amazonaws.com/"
data = { 'key': 'test.txt' }
files = { 'file': open('/tmp/test.txt', 'rb') }
r = requests.post(url, data=data, files=files)
print "status %s" % r.status_code
This works fine in python to upload a file , how do i do the same in GOlang , I tried something like below
package main
import (
"fmt"
"io/ioutil"
"log"
"net/http"
"os"
)
func SendPostRequest(url string, filename string) (string, []byte) {
client := &http.Client{}
data, err := os.Open(filename)
if err != nil {
log.Fatal(err)
}
req, err := http.NewRequest("POST", url, data)
req.Header.Set("Content-Type", "multipart/form-data")
if err != nil {
log.Fatal(err)
}
resp, err := client.Do(req)
if err != nil {
log.Fatal(err)
}
content, err := ioutil.ReadAll(resp.Body)
if err != nil {
log.Fatal(err)
}
return resp.Status, content
}
func main() {
status, content := SendPostRequest("https://bucket.s3.amazonaws.com/", "what.html")
fmt.Println(status)
fmt.Println(string(content))
}
So I got following error from S3
The body of your POST request is not well-formed multipart/form-data.
P.s : I have given full access to my S3 bucket policy and I am trying to upload without any credentials.Later I will update this to work only with my VPC .

我已经使用 aws-sdk-for-go 与 S3 进行交互。你可以尝试使用它。大多数 API 都有示例,所以很容易快速开始你的第一个版本。在这里查看 - https://docs.aws.amazon.com/sdk-for-go/api/service/s3/#S3.CreateMultipartUpload。

I have used aws-sdk-for-go for interacting with S3. You can try that. Most APIs have examples so it is fairly quick to get your first version going. Check here - https://docs.aws.amazon.com/sdk-for-go/api/service/s3/#S3.CreateMultipartUpload.

为您提供一种选择,您可以使用一个类似于Python的requests库的Go语言库。这将帮助您将Python代码转换为Golang。这是一个很棒的库:https://github.com/levigross/grequests。
您还可以在Awesome-Go上找到其他库的选择:https://github.com/avelino/awesome-go。
英文:
One option for you is to use a Go library which behaves like Python's requests library. This would help you in translating your Python code to Golang. Here is a wonderful library: https://github.com/levigross/grequests .
You can find other choices for libraries at Awesome-Go:
