摘要：
1.以MultipartBody.Part的形式上载文件（单文件上载）（表单模式）@Multipart@POST（“xxx/xxx”）调用上传（@PartMultipartBody.Partpart）；其中“photos”是服务器保留的文件参数名称。2.以RequestBody的形式上载文件（允许多次上载）/**上载多幅图像*/privatevoi
1.用MultipartBody.Part的方式上传文件（单文件上传）（表单方式）
@Multipart @POST("xxx/xxx") Call<ResponseBody> upload(@Part MultipartBody.Part part);
其中的“photos”是与服务器端预定的文件参数名
2.用RequestBody的方式上传文件（表单方式，可多上传）
/** * 多张图片上传 */ private void initUpateBitmap2() { //获取图片路径,这只是个简单的例子，项目开发中会有很多图片需要上传，一般从相册和相机里获取，并且保存到后台服务器时必须自己定义名字 // ，这样就不会发生图片替换（原因名字重复） File file = new File(Environment.getExternalStorageDirectory() + "/" + "retrofit/" + "ceshi.jpg"); File file2 = new File(Environment.getExternalStorageDirectory() + "/" + "retrofit/" + "ceshi2.jpg"); File file3 = new File(Environment.getExternalStorageDirectory() + "/" + "retrofit/" + "ceshi3.jpg"); File file4 = new File(Environment.getExternalStorageDirectory() + "/" + "retrofit/" + "ceshi4.jpg"); RequestBody requestBody = RequestBody.create(MediaType.parse("multipart/form-data"), file); RequestBody requestBody2 = RequestBody.create(MediaType.parse("multipart/form-data"), file2); RequestBody requestBody3 = RequestBody.create(MediaType.parse("multipart/form-data"), file3); RequestBody requestBody4 = RequestBody.create(MediaType.parse("multipart/form-data"), file4); RequestBody body = RequestBody.create(MediaType.parse("multipart/form-data"), file); //传一张图片就要增加一个参数 String name = "photo"; filename="ceshi.jpg""; String name2 = "photo"; filename="ceshi2.jpg""; String name3 = "photo"; filename="ceshi3.jpg""; String name4 = "photo"; filename="ceshi4.jpg""; HashMap<String, RequestBody> map = new HashMap<>(); map.put(name, requestBody); map.put(name2, requestBody2); map.put(name3, requestBody3); map.put(name4, requestBody4); RetrofitHelper.getInstance().uploadFile2(map, new RetrofitHelper.OnSuccessListener() { @Override public void onSuccess(Object o) { Log.e("", "成功"); } @Override public void onFaile() { Log.e("", "失败"); } }); }
通用的带参数和文件上传
接口定义，注意这个时候没有@Multipart @POST("upload") Call<ResponseBody> uploadFile(@Body RequestBody body);
RequestBody body=new MultipartBody.Builder().setType(MultipartBody.FORM) .addFormDataPart("userName","lange") .addFormDataPart("token","dxjdkdjkj9203kdckje0") .addFormDataPart("header",file.getName(),fileRQ) .build(); Call<ResponseBody> uploadCall = downloadService.uploadFile(body);
或者
@Multipart @POST("postFied") Call<Void> postFied(@PartMap Map<String,String> map, @Part MultipartBody.Part file); File file=new File("/sdcard/shumei.txt"); RequestBody body=RequestBody.create(MediaType.parse("application/octet-stream"),file); // RequestBody body=RequestBody.create(MediaType.parse("multipart/form-data"),file); MultipartBody.Part part =MultipartBody.Part.createFormData("file",file.getName(),body); Map<String, String> map = new HashMap<>(); map.put("name","123456"); Call<Void> liing = api.postFied(map,part);
