上传文件与改造2 [英] Upload file with Retrofit 2

问题描述

我试图做几天，我真的做了所有的事情。
以下是Postman中的请求：

我相信所有的GET参数都能正确写入。我想如何发送文件上传的问题。

 映射< String，RequestBody> map = new HashMap<>（）; 
 File file = new File（/ storage / emulated / 0 / ConstructSecure / d1940b05-76d1-4d98-b4b4-b04b8247c8cb.png）; 
 RequestBody requestBody = RequestBody.create（MediaType.parse（image / png），file）; 
 String fileName = file.getName（）; 
 map.put（attachment \; filename = \+ fileName +\，requestBody）; 
 
 // GET参数
 Map< String，String> params = new HashMap< String，String>（）; 
 params.put（inspectionUUID，inspectionUUID）; 
 params.put（noteUUID，noteUUID）; 
 params.put（attachmentUUID，attachmentUUID）; 
 params.put（noteType，noteType）; 
 params.put（modifiedTime，modifiedTime）; 
 
 Call< ; ResponseBody> call = service.upload（access_token，params，map）; 
 call.enqueue（）.... 
  

接口：

  @Multipart 
 @POST（api / MediaFiles / AddMediaFile ）
调用< ResponseBody>上传（
 @Header（Authorization）字符串授权，
 / * GET params * / @QueryMap Map< String，String> params，
 @ PartMap地图< Strin g，RequestBody>地图
）; 
  

任何人都可以帮忙吗？

解决方案我花了大量的时间进行搜索，如何发送文件作为字节流，因为所有的答案在Web解释上传通过RequestBody，但它不适用于我的情况。
所以，这里是解决方案：

  InputStream in = new FileInputStream（file）; 
 byte [] buf = new byte [in.available（）]; （in.read（buf）！= -1）; 
 while（in.read（buf）！= -1）; 
 RequestBody requestBodyByte = RequestBody 
 .create（MediaType.parse（application / octet-stream），buf）; 
 String content_disposition =attachment; filename = \+ fileName +\; 
 
 // GET参数
 Map< String，String> params = new HashMap< String，String>（）; 
 params.put（inspectionUUID，inspectionUUID）; 
 params.put（noteUUID，noteUUID）; 
 params.put（attachmentUUID，attachmentUUID）; 
 params.put（noteType，noteType）; 
 params.put（modifiedTime，modifiedTime）; 
 
呼叫< ResponseBody> call = service.upload（access_token，content_disposition，requestBodyByte，params）; 
  

接口：

  @POST（api / MediaFiles / AddMediaFile）
呼叫< ResponseBody>上传（
 @Header（Authorization）字符串授权，@ Header（Content-Disposition）字符串content_disposition，@Body RequestBody photo，
 / * GET params * / @QueryMap Map< String，String> ; params 
）; 
  

I trying to do that a few days, and I really did everything.. Here is how request looks in Postman:

I am sure, that all GET parameters were writing correctly. The problem in how I sending a file to upload, I suppose.

            Map<String, RequestBody> map = new HashMap<>();
            File file = new File("/storage/emulated/0/ConstructSecure/d1940b05-76d1-4d98-b4b4-b04b8247c8cb.png");
            RequestBody requestBody = RequestBody.create(MediaType.parse("image/png"), file);
            String fileName = file.getName();
            map.put("attachment\"; filename=\"" + fileName + "\"", requestBody);

            //GET parameters
            Map<String, String> params = new HashMap<String, String>();
            params.put("inspectionUUID", inspectionUUID);
            params.put("noteUUID", noteUUID);
            params.put("attachmentUUID", attachmentUUID);
            params.put("noteType", noteType);
            params.put("modifiedTime", modifiedTime);

            Call<ResponseBody> call = service.upload(access_token,params,map);
            call.enqueue()....

Interface:

@Multipart
    @POST("api/MediaFiles/AddMediaFile")
    Call<ResponseBody> upload(
            @Header("Authorization") String authorization,
            /* GET params */ @QueryMap Map<String, String> params,
            @PartMap Map<String, RequestBody> map
    );

Could anyone help me ?

解决方案

I spent a lot of time for search, how to send file as byte-stream, because all answers in web explain upload via RequestBody, but it's not working for my case. So, here is the solution:

InputStream in = new FileInputStream(file);
    byte[] buf = new byte[in.available()];
    while (in.read(buf) != -1) ;
    RequestBody requestBodyByte = RequestBody
            .create(MediaType.parse("application/octet-stream"), buf);
    String content_disposition = "attachment; filename=\"" + fileName + "\"";

    //GET parameters
    Map<String, String> params = new HashMap<String, String>();
    params.put("inspectionUUID", inspectionUUID);
    params.put("noteUUID", noteUUID);
    params.put("attachmentUUID", attachmentUUID);
    params.put("noteType", noteType);
    params.put("modifiedTime", modifiedTime);

    Call<ResponseBody> call = service.upload(access_token, content_disposition, requestBodyByte, params);

Interface:

 @POST("api/MediaFiles/AddMediaFile")
    Call<ResponseBody> upload(
            @Header("Authorization") String authorization,@Header("Content-Disposition") String content_disposition, @Body RequestBody photo,
            /* GET params */ @QueryMap Map<String, String> params
    );
