Question

我正在使用tastypie。当我想将数据发布到我的服务器时，我得到了：

“全局名称'http'未定义”

错误讯息。

我的curl命令是

curl --dump-header - -H "Content-Type: application/json" -X POST --data '{{"shop" : "/api/shop/1/","transactions" : [{"item" : "/api/item/53/","note" : "Normal"}]}' http://localhost:5000/api/order/

回溯：

{"error_message": "global name 'http' is not defined", "traceback": "Traceback (most recent call last):\n\n  File \"/Users/burakkilic/Documents/Projects/FineDine/Server/Django/finedine/venv/lib/python2.7/site-packages/tastypie/resources.py\", line 195, in wrapper\n    response = callback(request, *args, **kwargs)\n\n  File \"/Users/burakkilic/Documents/Projects/FineDine/Server/Django/finedine/venv/lib/python2.7/site-packages/tastypie/resources.py\", line 426, in dispatch_list\n    return self.dispatch('list', request, **kwargs)\n\n  File \"/Users/burakkilic/Documents/Projects/FineDine/Server/Django/finedine/venv/lib/python2.7/site-packages/tastypie/resources.py\", line 458, in dispatch\n    response = method(request, **kwargs)\n\n  File \"/Users/burakkilic/Documents/Projects/FineDine/Server/Django/finedine/venv/lib/python2.7/site-packages/tastypie/resources.py\", line 1317, in post_list\n    deserialized = self.deserialize(request, request.body, format=request.META.get('CONTENT_TYPE', 'application/json'))\n\n  File \"/Users/burakkilic/Documents/Projects/FineDine/Server/Django/finedine/finedine/api.py\", line 203, in deserialize\n    raise ImmediateHttpResponse(response=http.HttpBadRequest(e.message))\n\nNameError: global name 'http' is not defined\n"}

我把地址放在引号中，但没有任何改变。

我也把它写到我的资源中：

def deserialize(self, request, data, format='application/json'):
    try:
        return super(OrderResource, self).deserialize(request, data, format=format)
    except Exception as e:
        # if an exception occurred here it must be due to deserialization
        raise ImmediateHttpResponse(response=http.HttpBadRequest(e.message))

有什么问题？

Answer 1

该资源中的异常处理程序期望http位于本地名称空间中：

    raise ImmediateHttpResponse(response=http.HttpBadRequest(e.message))

如果您的代码中前面没有from tastypie import http之类的内容，则会失败。

顺便说一下，对于像这样的小事，我通常更喜欢使用像from tastypie.http import HttpBadRequest这样的东西，使用像pyflakes或flake8这样的工具立即捕捉错误的名字。如果对HttpBadRequest的唯一引用是在except块之类的不经常执行的代码中，那么在您发现此类问题之前可能需要一段时间。

为什么我要获得全球名称＆＃39; http＆＃39;没有定义错误？
