NodeJS + miekal/request:如何中止请求? [英] NodeJS + miekal/request : How to abort a request?

问题描述

我一直在试图中止请求几个小时，有人可以帮我吗?

I had been trying to abort a request for hours, can anyone help me please?

这就是我所拥有的:

app.get('/theUrl', function (req, resp) {

  var parser = new Transform();
  parser._transform = function(data, encoding, done) {
    var _this = this;
    // Process data here
  }.on("error", function(err){
    console.log(err);
  });

  var theRequest = request({
    'method' : 'GET',
    'url': '/anotherUrl',
    'headers' : {
      "ACCEPT"  : "text/event-stream"
    }
  }, function (error, response, body){
    if (error) {
      //Throw error
    }
  }).pipe(parser).pipe(resp);

  req.on("close", function(){
    parser.end();
    theRequest.abort(); //Doesn't work
  });
});

您可以看到它有点像流代理，因此，如果客户端取消了请求，我将捕获该请求，并且需要关闭或中止转发请求(theRequest).

As you can see its kinda a streaming proxy, so if clients cancels the request I catch it and need to close or abort the forwarding request (theRequest).

有什么想法吗?

谢谢！

推荐答案

从 https://github.com/mikeal/request/issues/772#issuecomment-32480203 :

从文档中

pipe()返回目标流

pipe() returns the destination stream

，因此您不再使用Request对象.在这种情况下，您要在ServerResponse上调用abort().改为执行此操作:

so you are no longer working with a Request object. In this case you're calling abort() on a ServerResponse. Do this instead:

var theRequest = request({ ... });
theRequest.pipe(parser);
theRequest.abort();

一切正常.
