Question

我正在尝试为Falcon框架编写一些pytests，并遵循here的说明。我想模拟一个POST请求。但是，我一直收到以下错误

测试/ test_app.py：29：   _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ .. / .. / harvester-venv / lib / python2.7 /site-packages/falcon/testing/client.py:170：   在json       return json.loads（self.text）/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/init.py:338：   在负载       return _default_decoder.decode（s）/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py:366：   在解码中       obj，end = self.raw_decode（s，idx = _w（s，0）.end（））

self =，s =''，idx =   0
def raw_decode(self, s, idx=0):
    """Decode a JSON document from ``s`` (a ``str`` or ``unicode``
        beginning with a JSON document) and return a 2-tuple of the Python
        representation and the index in ``s`` where the document ended.

        This can be used to decode a JSON document from a string that may
        have extraneous data at the end.

        """
    try:
        obj, end = self.scan_once(s, idx)
    except StopIteration:
      raise ValueError("No JSON object could be decoded") E           ValueError: No JSON object could be decoded
/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py:384： ValueError异常

这是我试图写的猎鹰测试。当我验证我在JSONlint.com上的data变量中放入的JSON时，它向我显示数据是有效的，因此问题似乎与格式不符。

import json

import pytest
from falcon import testing

from harvester.app import api


@pytest.fixture()

    return testing.TestClient(api)

    }
    result = client.simulate_post('/v1/track/analytics', body=json.dumps(data))
    print result.json

为什么会发生这种情况的任何线索？

Answer 1

不熟悉猎鹰。但在这里猜测：在你的灯具中你只需要传递api类/函数定义，但你不是在调用api()或调用api.create()。尝试：

@pytest.fixture()
def client():
    return testing.TestClient(api())  # or api.create() ?

同样错误的是您将积分发布到第29行，但您发布的代码段只包含27行。

Answer 2

调用result.json而不是触发验证错误的POSTed JSON。据推测，您正在测试的弹性搜索端点正在发回非JSON错误文档。

https://github.com/falconry/falcon/blob/master/falcon/testing/client.py#L153

如果结果不能解析为JSON，那么文档会说result.json会抛出错误，但这肯定会更清楚！

Answer 3

第一步是在标题中设置{“ Content-Type”：“ application / json”}。

此外，您可以如下调整发送有效载荷的方式：

import urllib.parse import urlencode

data = urlencode({
        "Type": "SubscriptionConfirmation",
        "MessageId": "0a069ec4-2e6f-4436-9f1d-aa55c3b048f9",
        "Token": "2336412f37fb68751e6e241d59b68cb9ca332001818266bdd4984dd60a76ff2c8a43220b28241ad0ae6659d6313bb2336e98d19bdbc52e0c99578ad43934324b5e73a20e9ad517741cf14a57793d052e9986038ee688a059b34e49746d106bcd597f18f7ff3560be204ef8cd339a3c5276bfa3cc784a7904c8720519387a0",
        "TopicArn": "arn:aws:sns:ap-south-1:141592612890",
        "SubscribeURL": "https://sns.ap-south-1.amazonaws.com/?Action=ConfirmSubscription&TopicArn=arn:aws:sns:ap-south-1:141592612890:harvester_test&Token=2336412f37fb687f5d51e6e241d59b68cb9ca332001818266bdd4984dd60a76ff2c8a41ad0ae6659d6313bb2336e98d19bdbc52e0c99578ad43934324b5e73a20e9ad517741cf14a57793d052e9986038ee688a059b34e49746d106bcd597f18f7ff3560be204ef8cd339a3c5276bfa3cc784a7904c8720519387a0",
        "Timestamp": "2017-06-01T13:22:49.849Z",
        "SignatureVersion": "1",
        "Signature": "Pj9F8PrgqPkSuLjHtrJ9pmh3ZH3kZBaLs5Ywx1C0rrOc4PJp3hYiria9SZr1Xm8uE549khxDFIdAsnGee9fSeO7tZWSNI3W3gRLVnIJ0uAjxU0oicj3P7NnGQ5kUnihKva//Q39RlZOIr4OsxTvOrXnag6M32aC3pEFdBaXJqO0iJJOokT+mmoWa9BWfHXnb/ORAigo50BXsVNSN92PRZAZ7qTeypZSU70EF1+vKNt7mbxrOE2/wpOtb7uDfg/ZW8yZQQqr100bnQVfStDSp6MzID+vupQhM2PR/gS84INA+VdOUhxll/kEkDE98tR9OrNz/PITts5XSg==",
        "SigningCertURL": "https://sns.ap-south-1.amazonaws.com/SimpleNotificationService-b95095beb82e8f6a04.pem"
})

headers = {"Content-Type": "application/json"}
result = client.simulate_post('/v1/track/analytics', body=data, headers=headers)

然后，这应该可以解决问题。让我知道。
