我刚开始从现有的网络库移植到Android的Volley.到目前为止,我已经成功实施了Volleys ImageLoader.现在,我正在尝试启动并运行我的第一个http调用,但是我发现了这个错误.

注意:我故意开始使用PATCH请求,因为我会经常使用它们.另外,我的Volley DOES版本支持补丁:https : //android.googlesource.com/platform/frameworks/volley/+/master/src/com/android/volley/Request.java https://android.googlesource.com /platform/frameworks/volley/+/master/src/com/android/volley/toolbox/HurlStack.java

堆栈跟踪:

补丁请求

    HashMap<String, …

我有一个简单的资源，我想执行DELETE。成功后，我想获取已删除对象的ID。根据文档，always_return_data- 指定所有HTTP方法（DELETE除外）应返回数据的序列化形式。

http://django-tastypie.readthedocs.org/en/latest/resources.html#always-return-data

class SimpleResource(resources.MongoEngineResource):
    class Meta:
        queryset = Simple.objects.all()
        resource_name = 'simple'
        allowed_methods = ('get', 'put', 'post', 'delete', 'patch')
        always_return_data = True

问题： 是否有序列化数据以返回已删除的对象？
