Python Eve：请求的资源上没有'Access-Control-Allow-Origin'标头

Question

我已经使用Python EVE框架编写了一个API。当试图从AngularJS应用程序访问API时，它显示了如下所示的错误：

XMLHttpRequest cannot load http://127.0.0.1:5000/user/jay3dec. Request header field Authorization is not allowed by Access-Control-Allow-Headers. 

X_DOMAINS = '*'
X_HEADERS = 'Authorization'

XMLHttpRequest cannot load http://127.0.0.1:5000/user/jay3dec. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access. 

    $scope.validate = function() {

    var encodedUserNameAndPassword = Base64.encode($scope.username + ':' + $scope.password);

    $http.defaults.headers.put = {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',
        'Access-Control-Allow-Headers': '*'
    };
    $http.defaults.headers.common['Authorization'] = 'Basic ' + encodedUserNameAndPassword;

    $http({
        method: 'GET',
        url: 'http://127.0.0.1:5000/user/jay3dec'
    }).
    success(function(data, status, headers, config) {
        console.log(data);
    }).
    error(function(data, status, headers, config) {
        alert(data);

    });
}

有什么问题吗

Answer 1

我也有类似的问题。

然后我了解到只有模式定义的API才会得到X_DOMAINS头的效果。使用app=Eve(settings=blah)和@app.route()这样的方法自行定义的api（如果有的话）不会受到X_DOMAINS头的影响。所以，在这种情况下，您需要编写自己的装饰器。
