How to Write Files or Folder to IPFS via the HTTP API
问题
我对IPFS的HTTP API文档感到困惑。以下是其中的一部分。
/api/v0/add
将文件或目录添加到IPFS。
//但是如何使用golang添加目录呢？看起来很简单，但没有一个示例来完成它
#cURL示例
curl -X POST -F file=@myfile "http://127.0.0.1:5001/api/v0/add?quiet=
英文:
I'm confused about the HTTP API docs of IPFS。next is part of it。
/api/v0/add
Add a file or directory to IPFS.
//but how to add a directory by golang? it look like so simple but no a example to finish it
#cURL Example
curl -X POST -F file=@myfile "http://127.0.0.1:5001/api/v0/add?quiet=<value>&quieter=<value>&silent=<value>&progress=<value>&trickle=<value>&only-hash=<value>&wrap-with-directory=<value>&chunker=size-262144&pin=true&raw-leaves=<value>&nocopy=<value>&fscache=<value>&cid-version=<value>&hash=sha2-256&inline=<value>&inline-limit=32"

我在同一个问题上工作过，并找到了这个可行的Shell解决方案：
https://community.infura.io/t/ipfs-http-api-add-directory/189/8
你可以用Go重新构建这个解决方案
package main
import (
"bytes"
"github.com/stretchr/testify/assert"
"io"
"io/ioutil"
"mime/multipart"
"net/http"
"os"
"strings"
"testing"
)
func TestUploadFolderRaw(t *testing.T) {
ct, r, err := createForm(map[string]string{
"/file1": "@/my/path/file1",
"/dir": "@/my/path/dir",
"/dir/file": "@/my/path/dir/file",
})
assert.NoError(t, err)
resp, err := http.Post("http://localhost:5001/api/v0/add?pin=true&recursive=true&wrap-with-directory=true", ct, r)
assert.NoError(t, err)
respAsBytes, err := ioutil.ReadAll(resp.Body)
assert.NoError(t, err)
t.Log(string(respAsBytes))
}
func createForm(form map[string]string) (string, io.Reader, error) {
body := new(bytes.Buffer)
mp := multipart.NewWriter(body)
defer mp.Close()
for key, val := range form {
if strings.HasPrefix(val, "@") {
val = val[1:]
file, err := os.Open(val)
if err != nil { return "", nil, err }
defer file.Close()
part, err := mp.CreateFormFile(key, val)
if err != nil { return "", nil, err }
io.Copy(part, file)
} else {
mp.WriteField(key, val)
}
}
return mp.FormDataContentType(), body, nil
}
或者使用https://github.com/ipfs/go-ipfs-http-client，这似乎是一个更好的方法。我正在研究它，等我知道如何使用它时会告诉你。

I worked on the same issue and found this working shell solution:
https://community.infura.io/t/ipfs-http-api-add-directory/189/8
you can rebuild this in go
package main
import (
"bytes"
"github.com/stretchr/testify/assert"
"io"
"io/ioutil"
"mime/multipart"
"net/http"
"os"
"strings"
"testing"
)
func TestUploadFolderRaw(t *testing.T) {
ct, r, err := createForm(map[string]string{
"/file1": "@/my/path/file1",
"/dir": "@/my/path/dir",
"/dir/file": "@/my/path/dir/file",
})
assert.NoError(t, err)
resp, err := http.Post("http://localhost:5001/api/v0/add?pin=true&recursive=true&wrap-with-directory=true", ct, r)
assert.NoError(t, err)
respAsBytes, err := ioutil.ReadAll(resp.Body)
assert.NoError(t, err)
t.Log(string(respAsBytes))
}
func createForm(form map[string]string) (string, io.Reader, error) {
body := new(bytes.Buffer)
mp := multipart.NewWriter(body)
defer mp.Close()
for key, val := range form {
if strings.HasPrefix(val, "@") {
val = val[1:]
file, err := os.Open(val)
if err != nil { return "", nil, err }
defer file.Close()
part, err := mp.CreateFormFile(key, val)
if err != nil { return "", nil, err }
io.Copy(part, file)
} else {
mp.WriteField(key, val)
}
}
return mp.FormDataContentType(), body, nil
}
or use https://github.com/ipfs/go-ipfs-http-client which seems to be a better way. I'm working on it and tell you when I know how to use it
