android的Retrofit 2无法同时发送头部和分块

import okhttp3.Interceptor;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

OkHttpClient.Builder builder = new OkHttpClient.Builder();
builder.addInterceptor(new Interceptor() {
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request originalRequest = chain.request();
        Request modifiedRequest = originalRequest.newBuilder()
                .header("Custom-Header", "header value")
                .build();
        return chain.proceed(modifiedRequest);
    }
});

OkHttpClient client = builder.build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/")
        .client(client)
        .build();

// 创建API接口
MyApiService apiService = retrofit.create(MyApiService.class);

// 发起请求
Call<ResponseBody> call = apiService.uploadFile(file);
call.enqueue(new Callback<ResponseBody>() {
    // 处理响应
    // ...
});
