android - OkHttp:如何将整个地图添加到单个键值参数中？

implementation 'com.squareup.okhttp3:okhttp:版本号'

OkHttpClient client = new OkHttpClient();

MultipartBody.Builder requestBodyBuilder = new MultipartBody.Builder()
        .setType(MultipartBody.FORM)
        .addFormDataPart("map", "map.jpg", RequestBody.create(MediaType.parse("image/jpeg"), mapData));

Request request = new Request.Builder()
        .url("请求URL")
        .post(requestBodyBuilder.build())
        .build();

try {
    Response response = client.newCall(request).execute();
    if (response.isSuccessful()) {
        // 处理成功响应
    } else {
        // 处理失败响应
    }
} catch (IOException e) {
    e.printStackTrace();
}
