wolfram-mathematica - 通过 Mathematica 上传到 ifile.it

Question

我想知道是否可以将文件从 Mathematica 上传到 ifile.it。我见过API ifile.it，但是，我仍然不知道它是如何工作的。此外，我在 Mathematica 中看到的最接近的例子是' Twittering with Mathematica '，但我不清楚，如何使用该示例中的 GET 请求。

提前致谢

Answer 1

设置 Java HttpClient 库。

<< JLink`

client = JavaNew["org.apache.commons.httpclient.HttpClient"]
(*
Out[3]= JLink`Objects`vm1`JavaObject17955866594508801
*)

确定要使用的服务器。

method = JavaNew["org.apache.commons.httpclient.methods.GetMethod", 
  "http://ifile.it/upload:api_fetch_upload_server"]

(*
Out[4]= JLink`Objects`vm1`JavaObject3301364646019073
*)

client@executeMethod[method]  

(*
Out[5]= 200
*)

id = "server_id" /. ImportString[method@getResponseBodyAsString[], "JSON"]

(*
Out[6]= "55"
*)

使用带有 FilePart 的 MultipartRequestEntity 通过 POST 请求将文件上传到服务器。

method = JavaNew["org.apache.commons.httpclient.methods.PostMethod", 
  "http://s" <> ToString[id] <> ".ifile.it/upload?apikey=" <> apikey]

(*
Out[7]= JLink`Objects`vm1`JavaObject25911718337052673
*)

filename = NotebookFileName[];

file = JavaNew["java.io.File", filename]

(*
Out[9]= JLink`Objects`vm1`JavaObject27844190972936193
*)

part = JavaNew["org.apache.commons.httpclient.methods.multipart.FilePart", 
  file@getName[], file]

(*
Out[10]= JLink`Objects`vm1`JavaObject17546309972000769
*)

part@setContentType["application/vnd.wolfram.mathematica"]

part@setName["Filedata"]

entity = JavaNew[
  "org.apache.commons.httpclient.methods.multipart.MultipartRequestEntity", 
{part}, method@getParams[]]

(*
Out[13]= JLink`Objects`vm1`JavaObject22100383232950273
*)

method@setRequestEntity[entity]

client@executeMethod[method]

(*
Out[15]= 200
*)

ImportString[method@getResponseBodyAsString[], "JSON"]

(*
Out[16]= {"file_key" -> "b8em0dc", 
 "file_md5" -> "acc9b7b3910b1e40188cf26ae3f20b80", 
 "file_mime" -> "text/plain", "file_name" -> "ifile.it.nb", 
 "file_size" -> "10473", "hash" -> "ca3d886713f64af6e9ffe6c3843d2eec", 
 "status" -> "ok", "url" -> "http://ifile.it/b8em0dc/ifile.it.nb"}
