OkHttp的multipartBody怎么取出key，value数据？

Question

添加数据如：multipartBody.addFormDataPart("username", "张三")取数据： List<MultipartBody.Part> parts = multipartBody.parts();
for (MultipartBody.Part part : parts) {
 
}part只能添加，不能取kv数据啊？谁知道怎么处理吗？我用拦截器拦截请求，需要multipartBody的kv参数作处理。（不要回答处理后再传）

   MultipartBody multipartBody = (MultipartBody) request.body();
                List<MultipartBody.Part> parts=multipartBody.parts();                for (MultipartBody.Part part:parts) {
                    if(part.body().contentType().type().equals("text")){
                        Headers headers=part.headers();
                        for (int i = 0; i <headers.names().size() ; i++) {
                            Log.d("ParameterInterceptor","headers======value="+headers.value(i));
                            String value=headers.value(i);//valueform-data; name="article_type"
                            String replaceValue="form-data; name=";//这段在MultipartBody.Part源码中看到
                            if(value.contains(replaceValue)){
                                String key=value.replace(replaceValue,"").replaceAll("\"","");;
                                Log.d("ParameterInterceptor","MultipartBody======key="+key);
                                map.put(key,bodyToString(part.body()));
                                builder.addPart(part);
                                break;
                            }
                        }
                    }
                    Log.d("ParameterInterceptor","MultipartBody======"+bodyToString(part.body()));
                    Log.d("ParameterInterceptor","MultipartBody======type=="+part.body().contentType().type());
                }
