AJAX in Django rendering JSON

我正在尝试将JSON对象传递给视图。此视图将在模板中打印出 JSON 对象。这只是一个测试，看看我在 Django 中传递了哪些数据。

在发送 JSON 对象之前，我有 javascript 来验证正在发送的数据。如果验证通过，则通过 AJAX 发送数据。

我目前无法将任何内容发送到所需的视图。我正在为POST 403.

这是我的代码要点：https://gist.github.com/liondancer/a9df593daeeecce7f180

.JS：

$(document).ready(function() {
    // Data to describe what kind of test
    var testData = {
        "timestamp": "",
        "hive": 0,
        "hdfs": 0,
        // Contains a list of testData objects
        "beacons":[]
    };

    var testRun = document.getElementById("test-form");
    testRun.addEventListener('submit', function(event) {
        event.preventDefault();
        var selectedTest = document.querySelector('input[name=test-select]:checked');
        alert(selectedTest);
        var testType = selectedTest.id;
        if (testType == "hdfs-test") {
            testData["hdfs"] = 1;
            testData["hive"] = 0;
        } else if (testType == "hive-test") {
            testData["hdfs"] = 0;
            testData["hive"] = 1;
        } else if (testType == "hdfs-hive-test") {
            testData["hdfs"] = 1;
            testData["hive"] = 1;
        } else {
        //    null
        }
        var events = document.getElementById("event-textarea").value;
        // check in valid input
        var eventSource = events.replace("],[","],,,,[");
        // beaconLists allows users to submit --> [{beacon1}, {beacon2}, ...], [{beacon3}, {beacon4}, ...]
        var beaconLists = eventSource.split(",,,,");
        for (var i = 0; i < beaconLists.length; i++) {
            // inspect one list in beaconLists [{beacon1}, {beacon2}, ...]
            var beaconList = beaconLists[i];
            try {
                // list of JSON objects
                var beaconObjList = JSON.parse(beaconList);
                for (var j = 0; j < beaconObjList.length; j++) {
                    var beaconObj = beaconObjList[j];
                    if (beaconObj["data"] && beaconObj["application"]) {
                    //    successful parse to find events
                    //    describe beacon being tested
                        alert("yes");
                        var beacon = {

                        // append to testData
                        testData["beacons"].push(beacon);

                        beacon = {};
