使用Java将JSON文档流式传输到Rest Web服务

[英]Streaming a JSON document to a Rest web service with java

原文 2016-06-22 03:27:08 7 1 java/ json/ api/ rest/ streaming

I've seen examples where you can use a http://docs.oracle.com/javaee/6/api/javax/ws/rs/core/StreamingOutput.html from a Rest api so that the restful respones can be a Json stream. 我看到了一些示例，您可以在其中使用来自Rest api的http://docs.oracle.com/javaee/6/api/javax/ws/rs/core/StreamingOutput.html ，以便宁静的响应可以是Json流。 This makes it so you can start processing JSON tokens as they come in instead of waiting until the whole thing is there. 这样一来，您就可以开始处理传入的JSON令牌，而不必等到整个事情都在那里。

Now i'm interested in the other way. 现在我对另一种方式感兴趣。

The flow: 流程：

The client opens a stream to a Rest api endpoint. 客户端打开到Rest api端点的流。
The client starts sending data through the stream. 客户端开始通过流发送数据。
The server while reading the stream can start working on the data before client is fully done sending it. 在读取流时，服务器可以在客户端完全完成发送数据之前开始处理数据。

Does such a feature exist? 是否存在这样的功能？

The only idea I have come up with is to have the client stream to a local file then send the server a URL to that file to stream from. 我想出的唯一想法是让客户端流到本地文件，然后向服务器发送指向该文件的URL。

maybe you can use java.nio(or Socket) to create a server and clients. 也许您可以使用java.nio（或Socket）创建服务器和客户端。

client read data and send the data(json?string?) to server one by one(or any other definite quantity) 客户端读取数据并将数据（json？string？）一一（或任何其他确定数量）发送到服务器

when the data received by server then server start to process it. 当服务器接收到数据时，服务器开始处理它。 and client continue to read remaining data and continue to send it to server. 并且客户端继续读取剩余数据，并继续将其发送到服务器。
