java - OKHTTP:如何测量请求和响应中的总字节数？

Question

正在使用 okhttp3 将 POST 一个 JSON 负载发送到网络服务器。我们想知道请求的总字节数和 POST 请求的响应。最终，我们想要获得数据吞吐量。这是代码:

OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
    .url(url)
    .post(body)
    .build();    
mBytesSent += request.body.contentLength();  // Payload byte count
mBytesSent += request.headers().size();
mBytesSent += request.tag().toString().length();

Response response = client.newCall(request).execute()  

mBytesRecd += response.body().contentLength();
mBytesRecd += response.headers().toString().length();
mBytesRecd += response.message().length();

这是 POST 的完整字节数吗？

如果您对估算结果满意，可以为此使用 EventListener

        override fun requestHeadersEnd(call: Call, request: Request) {
            bytesTransferred += request.headers.byteCount()
        }

        override fun requestBodyEnd(call: Call, byteCount: Long) {
            bytesTransferred += byteCount
        }

        override fun responseHeadersEnd(call: Call, response: Response) {
            bytesTransferred += response.headers.byteCount()
        }

        override fun responseBodyEnd(call: Call, byteCount: Long) {
            bytesTransferred += byteCount
        }
