英文:
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 mainimport ("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 requestsurl = "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 mainimport ("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。

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:
