OkHttp MultipartBody uploadFile 單張圖片和多張上傳 詳解

api文件編寫：
@Multipart
@POST("public/uploadFile/uploadFiles.api")//單張上傳圖片
Observable<Result<FileUploadRData>> upload(@Part MultipartBody.Part file);
@Multipart
@POST("public/uploadFile/uploadFiles.api")//多張上傳圖片
Observable<Result<FileUploadRData>> uploads( @Part List<MultipartBody.Part>  file);

HttpMethods文件編寫：

public Observable<FileUploadRData> upload(MultipartBody.Part doc) {
     return Direct.create(demoService.upload(doc));
 }
 public Observable<FileUploadRData> uploads(List<MultipartBody.Part>  doc) {
     return Direct.create(demoService.uploads(doc));
 }

實踐代碼模塊：

         單個文件上傳：

        File file = new File(cropImageUri.getPath());//文件路徑
//        //MediaType 有多種類型
        RequestBody requestBody = RequestBody.create(MediaType.parse("text/x-markdown; charset=utf-8"), file);
       //files 上傳參數
        MultipartBody.Part part= MultipartBody.Part.createFormData("files", file.getName(), requestBody);

        HttpMethods.getInstance().upload(part).subscribe(new MyObserver<FileUploadRData>() {......}

  多個文件上傳：

MultipartBody.Builder builder = new MultipartBody.Builder().setType(MultipartBody.FORM);
for (String path : paths) {//List<String> paths多個文件本地路徑地址
    Log.d("TAG", path);
    File file = new File(path);
    RequestBody requestBody = RequestBody.create(MediaType.parse("text/x-markdown; charset=utf-8"), file);
    builder.addFormDataPart("files",file.getName(),requestBody);//files 文件上傳參數
}
List<MultipartBody.Part> parts = builder.build().parts();

HttpMethods.getInstance().uploads(parts).subscribe(new MyObserver<FileUploadRData>() {.....}

文件FileUploadRData類是返回數據

/**
 * 返回文件url  外部訪問鏈接
 */
private List<String> fileName;

OK  ，是不是很簡單！
