在nodejs中运行http请求以测试我的rest api时，它停止了，为什么？

Question

I have a rest api working perfectly and now instead of manually testing it with postman I have written http requests in order to test CRUD operations. I know for a fact that all the requests are working as they give me status codes of 200.

My problem is when running the tests command line will show it ran through nearly all of them but it will not go beyond some of the GET requests (even though I have the same code for requests of the same type earlier in the code.

When I comment out the GET request where it gets stuck, it runs the requests after that one with no problem.

This is the code I have for my GET requests:

var options = {
    host: 'localhost',
    port: 4000,
    path: '/api/services/00001/method/01/args/01'
};
http.get(options, function(res) {
   console.log("Got response: " + res.statusCode+"\nGET argument 01 for user 00001 method 01.\n\n ");
}).on('error', function(e) {
   console.log("Got error: " + e.message);
});

Am I missing something that will occasionally get the code to stop running? Any help is appreciated.

I can add code for my other operations as well if needed(POST, PUT, DELETE).

After running my entire code with nothing commented out, I realized that it also stops in my second delete request, code is as follows:

var options = {
   host: 'localhost',
   port: 4000,
   path: '/api/services/00001/method/01',
   method: 'DELETE'
};

http.get(options, function(res) {
  console.log("Got response: " + res.statusCode +"\nDELETE method 01 for user 00001.\n\n ");
}).on('error', function(e) {
  console.log("Got error: " + e.message);
});

The solution could be one or both of:

• Setting agent: false in your request options . This prevents the request from using the global http agent socket pool, meaning the request will get its own new socket every time. I have seen strange things where requests never start because of node's http agent implementation. The one thing you should be aware of though is your OS user's (the one the process is running under) file descriptor limits. If you do a lot of concurrent requests using agent: false , you may need to up that OS limit.

• Use res.resume() in your request callback to drain any response data from the server whenever you don't care about it. Doing so may ensure that a socket from the http agent socket pool is available for use by another request.
