Go 如何以文件为主体复制cURL命令,go,curl,generator,hootsuite,Go,Curl,Generator,Hootsuite,有人能帮我把这个cURL命令转换成Go吗 curl -X PUT -H 'Content-Type: image/jpg' \ -H "Content-Length: 132093" \ -T "/Users/ikmal/Downloads/catcute.jpg" \ "https://hootsuite-video.s3.amazonaws.com/production/18395606_a9245dd7-73d6-4392-af4a-1cd9bf359cfb.

有人能帮我把这个cURL命令转换成Go吗

curl -X PUT -H 'Content-Type: image/jpg' \
     -H "Content-Length: 132093" \
     -T "/Users/ikmal/Downloads/catcute.jpg" \
     "https://hootsuite-video.s3.amazonaws.com/production/18395606_a9245dd7-73d6-4392-af4a-1cd9bf359cfb.jpg?AWSAccessKeyId=AKIAIM7ASX2JTE3ZFAAA&Expires=1543304067&Signature=n9sZkQ%2BF1DGuiYHqixrrvmoxIXQ%3D"
我已经试过了，比如：

它创建了如下Go代码：

req, err := http.NewRequest("PUT", "https://hootsuite-video.s3.amazonaws.com/production/18395606_a9245dd7-73d6-4392-af4a-1cd9bf359cfb.jpg?AWSAccessKeyId=AKIAIM7ASX2JTE3ZFAAA&Expires=1543304067&Signature=n9sZkQ%2BF1DGuiYHqixrrvmoxIXQ%3D", nil)
if err != nil {
    // handle err
}
req.Header.Set("Content-Type", "image/jpg")
req.Header.Set("Content-Length", "132093")

resp, err := http.DefaultClient.Do(req)
if err != nil {
    // handle err
}
defer resp.Body.Close()

但两者都没有给我正确的代码，因为当我在project上运行这些代码时，它会返回一些错误，因为它不会生成此部分：

-T "/Users/ikmal/Downloads/catcute.jpg"
并将其生成为“nil”

更新：

我对此问题所做的是添加以下代码：

file, err := os.Open("/Users/ikmal/Downloads/catcute.jpg")
if err != nil {
    panic(err)
}
defer file.Close()
所以我将变量“file”放入body请求中，下面是我的最终代码：

func main(){
    file, err := os.Open("/Users/ikmal/Downloads/catcute.jpg")
    if err != nil {
        panic(err)
    }
    defer file.Close()

    client := &http.Client{}
    req, err := http.NewRequest("PUT", "https://hootsuite-video.s3.amazonaws.com/production/18395606_a9245dd7-73d6-4392-af4a-1cd9bf359cfb.jpg?AWSAccessKeyId=AKIAIM7ASX2JTE3ZFAAA&Expires=1543304067&Signature=n9sZkQ%2BF1DGuiYHqixrrvmoxIXQ%3D", file)
    if err != nil {
        log.Fatal(err)
    }
    req.Header.Set("Content-Type", "image/jpg")
    req.Header.Set("Content-Length", "132093")
    resp, err := client.Do(req)
    if err != nil {
        log.Fatal(err)
    }
    bodyText, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("%s\n", bodyText)
}
然后，当我构建并运行该程序时，它会返回如下响应：

// Generated by curl-to-Go: https://mholt.github.io/curl-to-go

req, err := http.NewRequest("PUT", "https://hootsuite-video.s3.amazonaws.com/production/18395606_a9245dd7-73d6-4392-af4a-1cd9bf359cfb.jpg?AWSAccessKeyId=AKIAIM7ASX2JTE3ZFAAA&Expires=1543304067&Signature=n9sZkQ%2BF1DGuiYHqixrrvmoxIXQ%3D", nil)
if err != nil {
    // handle err
}
req.Header.Set("Content-Type", "image/jpg")
req.Header.Set("Content-Length", "132093")

resp, err := http.DefaultClient.Do(req)

    // handle err

defer resp.Body.Close()

package main

这个错误似乎来自标题问题，但我确信我键入的标题是正确的。我错过了什么吗？

您必须使用
多部分上传图像内容


f, err := os.Open("./Users/ikmal/Downloads/catcute.jpg")
if err != nil{
    log.Fatal(err)
}
defer f.Close()

var buf = new(bytes.Buffer)
writer := multipart.NewWriter(buf)

part, _ := writer.CreateFormFile("image", "dont care about name")
io.Copy(part, f)

writer.Close()

req, _ := http.NewRequest("POST", "https://hootsuite-video.s3.amazonaws.com/production/18395606_a9245dd7-73d6-4392-af4a-1cd9bf359cfb.jpg?AWSAccessKeyId=AKIAIM7ASX2JTE3ZFAAA&Expires=1543304067&Signature=n9sZkQ%2BF1DGuiYHqixrrvmoxIXQ%3D", buf)
req.Header.Set("Content-Type", writer.FormDataContentType())

client := &http.Client{}
res, _ := client.Do(req)
defer res.Body.Close()
b, _ := ioutil.ReadAll(res.Body)
fmt.Println(string(b))
