在Retrofit的请求中，需要手动添加所有要传递的头部参数到OkHttp的请求构建器中，例如：

val accessToken = "abcdef12345"
val userId = "12345"

val headers = HashMap()
headers["Authorization"] = "Bearer $accessToken"
headers["userId"] = userId

val okHttpClient = OkHttpClient.Builder()
    .addInterceptor { chain ->
        val originalRequest = chain.request()
        val requestBuilder = originalRequest.newBuilder()
            .headers(Headers.of(headers))
            .method(originalRequest.method(), originalRequest.body())
        chain.proceed(requestBuilder.build())
    }
    .build()

Retrofit.Builder()
    .baseUrl(BASE_URL)
    .client(okHttpClient)
    .addConverterFactory(GsonConverterFactory.create())
    .build()
    .create(ApiService::class.java)
    .makeApiCall()

在这个示例中，我们手动将“Authorization”和“userId”头部参数添加到OkHttp的请求构建器中，确保它们会被包含在请求中。
