如何在 android studio 中通过 okhttps 仅上传最后一个文件上传多个文件

Question

我正在使用 okhttps 3 将多个文件上传到服务器 但它总是上传最后一个文件而不是所有文件 我的代码在

下面

解释码：-

1.get 用户 ID 形式共享偏好

2.create okhttps 客户端

3 检查文件是否为空

4.create multipartbody 添加参数和数据

5.create 一个 for 循环附加参数

中的文件

6.call 请求正文并获取响应

public static void TaskAdd(final Activity activity, final String task_title, final String employees, final String priority, final String add_due_date, final String task_detail, final File[] file, final FragmentManager fragmentManager, final Dialog dialog) {

您正在通过传递相同的名称覆盖相同的文件，将其也更改为 file[] 或传递为 file1 和 file2

 for (int i = 0; i < file.length; i++) {
                    Log.d(TAG, "TaskAdd: File " + file[i]);
                    if (file[i].exists()) {
                        Log.d(TAG, "TaskAdd: "+i);
                        //body.addPart()
                        body.addFormDataPart("files["+i+"]", file[i].getName(), RequestBody.create(MediaType.parse("Image/*"), file[i]));

                        Log.d(TAG, "TaskAdd: "+ body.getClass().getName());
                    } else {
                        Log.d(TAG, "TaskAdd: No file found");
                    }
                }
