/*
* vertx创建服务接收请求并返回：
* 创建HttpServer-->server.requestHandler---》request.handler---》request.response()
*
* 处理表单请求
* 表单请求分为两种方式：
* 1 普通请求 application/x-www-form-urlencoded
* 2 多文件请求 multipart/form-data
* 对于普通请求，起参数均可以从URL中获取，可像处理一般请求一样处理
* 对于multipart/form-data请求
* server.requestHandler(request -> {
request.setExpectMultipart(true);
request.endHandler(v -> {
// The body has now been fully read, so retrieve the form attributes
MultiMap formAttributes = request.formAttributes();
});
});
处理文件上传
server.requestHandler(request -> {
request.setExpectMultipart(true);
request.uploadHandler(upload -> {
System.out.println("Got a file upload " + upload.name());
});
});

File uploads can be large we don’t provide the entire upload in a single buffer as that might result in
memory exhaustion, instead, the upload data is received in chunks:

request.uploadHandler(upload -> {
upload.handler(chunk -> {
System.out.println("Received a chunk of the upload of length " + chunk.length());
});
});
