将大型阵列传输到客户端

I need to transfer a large array of 16 bit integers to a client using an AJAX request to a web service. This array is essentially grey-scale pixel data for an image with some additional meta data.

我需要使用对Web服务的AJAX请求将大量16位整数传输到客户端。该阵列本质上是具有一些附加元数据的图像的灰度像素数据。

The original image is in a proprietary format that is not supported by browsers. A typical image is 2000px x 4000px so the array could contain 8,000,000+ 16bit values.

原始图像采用浏览器不支持的专有格式。典型图像为2000px x 4000px,因此阵列可包含8,000,000+ 16位值。

Is it acceptable to make one AJAX request and return this entire array in one response or should I split into into smaller chunks and request each individually? If it is an accepted practice to transfer the whole array in one response, would I have to handle unreliable connections during the request (or does that come 'out of the box' in the browsers)?

是否可以制作一个AJAX请求并在一个响应中返回整个数组,还是应该分成更小的块并单独请求每个?如果在一个响应中传输整个数组是公认的做法,我是否必须在请求期间处理不可靠的连接(或者在浏览器中是否“开箱即用”)?

We are writing both the client and the web service so we are entirely flexible on our approach.

我们正在编写客户端和Web服务,因此我们对方法完全灵活。

The data you need to transfer is more than 16 MB in size, but you should get a smaller size by using gzip given the fact that you're working with unarchived data. Also you should think about a very fast serialization format (because you will need a lot of processing both on the client and the server to serialize/deserialize the data).

您需要传输的数据大小超过16 MB,但考虑到您正在使用未归档数据这一事实,您应该使用gzip获得更小的大小。您还应该考虑一种非常快速的序列化格式(因为您需要在客户端和服务器上进行大量处理才能序列化/反序列化数据)。
