Android: okhttp uploads mp4 files through post and carries parameters

Main method

Just pass two parameters

 protected void post_file(final String url,File file) {
        OkHttpClient client = new OkHttpClient();
        MultipartBody.Builder requestBody = new MultipartBody.Builder().setType(MultipartBody.FORM);
        if(file != null){
            RequestBody body = RequestBody.create(MediaType.parse("mp4/*"),file);
            String filename = file.getName();
            requestBody.addFormDataPart("file",file.getName(),body).addFormDataPart("type","event");
        }
        }
        Request request = new Request.Builder().url(url).post(requestBody.build()).tag(EventsReportedActivity.this).build();
        // readTimeout("请求超时时间",时间单位);
        client.newBuilder().readTimeout(5000,TimeUnit.MILLISECONDS).build().newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call,IOException e) {
                Log.i("lfq","onFailure");
            }
            @Override
            public void onResponse(Call call,Response response) throws IOException {
                if (response.isSuccessful()) {
                    String str = response.body().string();
                    Log.i("post_file：：",response.message() + ",body " + str);
                } else {
                    Log.i("post_file：：",response.message() + " error : body " + response.body().string());
                }
            }
        });
    }

transfer

The mp4 file corresponding to the path is real

 File   file = new File("/storage/emulated/0/DCIM/ZyfVideo/VID_20210316_175950.mp4");
post_file("url地址",file);
