从未调用过AngularJS $ http错误函数

Question

我有简单的代码：

$http.get("/api/test")
    .success(function (data, status, headers, config) {
        console.log(data);
        return data;
    }).error(function (data, status, headers, config) {
        alert("error");
        return status;
});

它工作正常，但即使我从服务器返回404（未找到），也永远不会调用错误函数…在这种情况下，它会调用状态为404的“成功”函数…

那是对的吗？

谢谢

Answer 1

问题出在您的Web服务器上，它将content-length设置为0，这意味着这是一个有效值，如您在HTTP /
1.1规范中
所见。

我还在JSFiddle上举了一个例子，展示了错误和成功的例子。看这里。
