Question

我正在尝试对我的机器上运行的Laravel（5.2）应用程序进行简单的简单卷曲：

curl -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:7.0.1) Gecko/20100101 Firefox/7.0.1" http://192.168.1.65:8000/pt

结果如下：

请求标题：

*   Trying 192.168.1.65...
* Connected to 192.168.1.65 (192.168.1.65) port 8000 (#0)

> Host: 192.168.1.65:8000
> Accept: */*
> User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

响应标题和正文：

我觉得这很奇怪，因为如果我使用来自python 3.x的lib请求：

import requests

headers = {'User-Agent' : 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:7.0.1) Gecko/20100101 Firefox/7.0.1'}
req = requests.get('http://192.168.1.65:8000/pt', headers=headers)
print(req.text)

响应是页面中的所有html（这就是要发生的事情）

PS：我还在-L使用了curl标记，因此它可以暂停重定向，但它似乎最终会进入无限循环（curl: (47) Maximum (50) redirects followed）

为什么这是hapening？怎么解决？

Answer 1

您正在设置Cookie，如果该Cookie不存在，您可以使用302 Found将用户重定向到同一页面。具体而言，您需要检查lang Cookie。

虽然Python请求（显然）在重定向时保留了cookie，但curl默认情况下不会这样做。您可以通过添加cookie jar（存储cookie的文件，-c cookies.txt）或手动设置cookie（-b lang=pt）来启用此功能。

例如：

$ curl -c cookies.txt -A 'Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0' -LI lemos.migueldvl.com/pt

Curl和Laravel，总是重定向
