我有
react应用程序尝试使用whatwg-fetch从其余的api获取数据.
var header = {"Content-Type": "multipart/form-data", 'Origin': 'https://foo.bar', 'Access-Control-Request-Method': 'GET', 'Access-Control-Request-Headers': 'X-Requested-With'};
var options = {method: 'GET', credentials: 'include', headers: header};
fetch('https://myrest.api/foo', options)...
但我说不能得到任何数据
Fetch API cannot load https://foo.bar.
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'https://foo.bar' is therefore not allowed access.
The response had HTTP status code 403.
If an opaque response serves your needs, set the request's mode to 'no-cors'
to fetch the resource with CORS disabled.
当我尝试使用curl获取数据时,它可以工作
curl -H "Origin: …我使用Python 3.4与Pyside 1.2.4和PyQt 4.8.7,当我尝试将信号连接到插槽时,它说:
'PySide.QtCore.Signal'对象没有属性'connect'
我正在使用MVC:
模型:
from PySide.QtCore import Signal
class Model(object):
def __init__(self):
self.updateProgress = Signal(int)
控制器:
class Controller(QWidget):
"""
MVC Pattern: Represents the controller class
"""
def __init__(self, parent=None):
super().__init__(parent)
self.model = Model()
self.model.updateProgress.connect(self.setProgress)
当我在Pycharm中查找Class时,通过按住CTRL并单击Signal类,它看起来如下所示:
class Signal(object):
""" Signal """
def __call__(self, *args, **kwargs): # real signature unknown
""" Call self as a function. """
pass
def __getitem__(self, *args, **kwargs): # real signature unknown
""" Return self[key]. """
pass
def __init__(self, *args, **kwargs): # real signature unknown …我得到了以下项目结构
project
-- build.gradle
-- gradle
| -- java.gradle
| -- artifacts.gradle
在我的root build.gradle中,我写道
apply from: 'gradle/artifacts.gradle'
在我的artifacts.gradle中,我构建了一个耳朵,并希望将war任务(也在artifacts.gradle)设置为部署依赖关系
project(path: ':myWar', configuration: 'myWar')
现在gradle抛出了我的错误 Project with path <path> could not be found in root project <project>.
我究竟做错了什么？
