javascript - 如何通过 webhook 将 json 格式的字符串作为有效负载传递给 iron.io worker？

Question

如何使用 webhook 将 json 格式的字符串提交到以下脚本？

下面是我想要读取负载的 iron.io 脚本。

import sys, json

sys.argv[8]

payload_file = None
payload = None


    for i in range(len(sys.argv)):

        if sys.argv[i] == "-payload" and (i + 1) < len(sys.argv):
            payload_file = sys.argv[i + 1]
            with open(payload_file,'r') as f:
                payload = json.loads(f.read())
                print "printing resulting payload: " + str(payload)
            break

当我在平台内对一个 json 格式的字符串进行排队时，我得到了想要的结果，您可以在下面看到:

我输入的json格式字符串

{u'env': u'production'}

Iron.io 中显示的日志

printing resulting payload: {u'env': u'production'}

我想通过使用以下 javascript 的 webhook 调用来完成相同的结果。

post('https://worker-aws-us-east-1.iron.io/2/projects/PROJECTKEY/tasks/webhook?code_name=CODENAME&oauth=OAUTH', {
    payload: {
        "tasks": [{
            "code_name": "firebase_email_webhook",
            "payload": "{u'env': u'production'}"
        }]
    }
})


function post(path, params, method) {
    method = method || "post"; // Set method to post by default if not specified.

    var form = document.createElement("form");
    form.setAttribute("method", method);
    form.setAttribute("action", path);

    for (var key in params) {
        if (params.hasOwnProperty(key)) {
            var hiddenField = document.createElement("input");
            hiddenField.setAttribute("type", "hidden");
            hiddenField.setAttribute("name", key);
            hiddenField.setAttribute("value", params[key]);

            form.appendChild(hiddenField);
        }
    }

    document.body.appendChild(form);
    form.submit();
}

webhook 调用工作正常，但问题是我收到以下错误:

Traceback (most recent call last):
  File "firebase_email_webhook.py", line 32, in <module>
    payload = json.loads(f.read())
  File "/usr/lib/python2.7/json/__init__.py", line 326, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 384, in raw_decode
    raise ValueError("No JSON object could be decoded")

Webhook 端点接收未修改的 POST 内容作为负载。只需发送 json 即可。

代码借自https://stackoverflow.com/a/6587249/1758892

var arr = { City: 'Moscow', Age: 25 };
$.ajax({
    url: 'Ajax.ashx',
    type: 'POST',
    data: JSON.stringify(arr),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    async: false,
    success: function(msg) {
        alert(msg);
    }
});
