Content-Disposition 值中 42 处的意外字符 0x662：表单数据；名称=“用户文件”；文件名="IMG_??????????_?????????.jpg"

Question

我在我的 android 应用程序中使用本地化

虽然语言设置为阿拉伯语，但在 okhttp (okhttp:3.12.0) 的文件上传过程中出现此错误

E/AndroidRuntime: FATAL EXCEPTION: main

我的代码块是

final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");
            formBody = new MultipartBody.Builder()
                    .setType(MultipartBody.FORM)
                    .addFormDataPart("action", "updateprofile")
                    .addFormDataPart("userfile", file.getName(), RequestBody.create(MEDIA_TYPE_PNG, file))
                    .addFormDataPart("userid", user.getId())
                    .addFormDataPart("name", name.getText().toString())
                    .build();

我该如何解决这个问题

Answer 1

尝试像这样编码文件名：

URLEncoder.encode(file.getName(), "utf-8")

这样你的代码就变成

final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/*");
        formBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("action", "updateprofile")
                .addFormDataPart("userfile", URLEncoder.encode(file.getName(), "utf-8"), RequestBody.create(MEDIA_TYPE_PNG, file))
                .addFormDataPart("userid", user.getId())
                .addFormDataPart("name", name.getText().toString())
                .build();
