Question

我一直在阅读http://www.mobify.com/blog/http-requests-are-hard/，其中讨论了请求可能遇到的各种类型的错误。本文着重于捕捉每一个。我想在发生任何错误时简单地打印出错误类型。在文章中，一个例子是：

selectAll = function (event) {
        var self = this;
        $('.template-item-select').each(function () {
            this.checked = self.checked;
        });
    }

有没有办法用伪代码重写最后2行：

url = "http://www.definitivelydoesnotexist.com/"

try:
    response = request.get(url)
except requests.exceptions.ConnectionError as e:
    print "These aren't the domains we're looking for."

Answer 1

来自my other answer：

请求明确提出的所有异常都来自 requests.exceptions.RequestException 。

所以这应该抓住一切：

try:
    response = requests.get(url)
except requests.exceptions.RequestException as e:
    print e

Answer 2

所有请求异常都从requests.exceptions.RequestException继承，因此您可以：

try:
    ....
    ....
except requests.exceptions.RequestException as e:
    # Do whatever you want to e
    pass

使用请求库打印出错误
