Test concurrent requests to a REST based web server

Question

如何向基于 REST 的 Web 服务器模拟数以千计的 GET 和 PUT 请求？是否有可用的工具？如果有，有哪些可用的工具？

Answer 1

ab - Apache HTTP server benchmarking tool http://httpd.apache.org/docs/2.0/programs/ab.html

This is a great tool for testing REST APIs.

Example:

ab -c 100 -n 100 http://service/path/to/resource

In this example:

• "-c 100" means 100 concurrent requests and
• "-n 100" means 100 requests

I know its an old question however I needed a simple AJAX based Script to Test Multiple Concurrent Connections. If any of you have similar requirements then you can also use like this one for your tests.

Please take a look the this js fiddle link or See attached (whichever suits you as both points to the same javascript code)

 var interval; var queue = []; var globalElapsedTime; function getUrl() { return $.trim($("#txtAjayUrl").val()); } $("#btnLaunchRequests").on("click", function () { queue = []; $("#divTimeElapsed").html("<i>calculating</i>"); globalElapsedTime = window.performance.now(); $("#divRequestStatus").show(); $("#btnLaunchRequests").prop("disabled", true); var totalRequests = 50; var inputValue = $("#txtNumberOfConcurrentRequests").val(); totalRequests = inputValue.trim(); $("#divTotalNumberOfProcessed").html(totalRequests.toString()); if (interval != null && interval != undefined) { clearInterval(interval); } interval = window.setInterval(function () { $("#divNumberOfCurrentRequests").text(queue.length); }, 500); for (let i = 1; i <= totalRequests; i++) { console.log("Loop No. " + i); if (i == totalRequests) { $.get(getUrl(), function (data) { queue.push("1"); $("#btnLaunchRequests").prop("disabled", false); $("#divNumberOfCurrentRequests").text(queue.length); //clearInterval(interval); }).always(function () { $("#btnLaunchRequests").prop("disabled", false); globalElapsedTime = window.performance.now() - globalElapsedTime; globalElapsedTime = Math.round((globalElapsedTime / 1000) * 100) / 100; console.log("%cLast Result Processed in " + globalElapsedTime + " Seconds.", "color:green"); $("#divTimeElapsed").text(globalElapsedTime + " seconds"); }); } else { $.get(getUrl(), function (data) { queue.push("1"); }); } } });

试试jmeter，有第三方REST插件： http : //smartrics.blogspot.co.uk/2009/04/jmeter-to-test-robustness-of-system.html

几乎任何 HTTP 性能测试工具，无论是商业的还是开源的，都可用于对 REST 接口进行性能测试。
