python requests.get() 返回一个空字符串

Question

当我运行下面的代码时，它返回一个空字符串

url = 'http://www.allflicks.net/wp-content/themes/responsive/processing/processing_us.php?draw=5&columns[0][data]=box_art&columns[0][name]=&columns[0][searchable]=true&columns[0][orderable]=false&columns[0][search][value]=&columns[0][search][regex]=false&columns[1][data]=title&columns[1][name]=&columns[1][searchable]=true&columns[1][orderable]=true&columns[1][search][value]=&columns[1][search][regex]=false&columns[2][data]=year&columns[2][name]=&columns[2][searchable]=true&columns[2][orderable]=true&columns[2][search][value]=&columns[2][search][regex]=false&columns[3][data]=genre&columns[3][name]=&columns[3][searchable]=true&columns[3][orderable]=true&columns[3][search][value]=&columns[3][search][regex]=false&columns[4][data]=rating&columns[4][name]=&columns[4][searchable]=true&columns[4][orderable]=true&columns[4][search][value]=&columns[4][search][regex]=false&columns[5][data]=available&columns[5][name]=&columns[5][searchable]=true&columns[5][orderable]=true&columns[5][search][value]=&columns[5][search][regex]=false&columns[6][data]=director&columns[6][name]=&columns[6][searchable]=true&columns[6][orderable]=true&columns[6][search][value]=&columns[6][search][regex]=false&columns[7][data]=cast&columns[7][name]=&columns[7][searchable]=true&columns[7][orderable]=true&columns[7][search][value]=&columns[7][search][regex]=false&order[0][column]=5&order[0][dir]=desc&start=0&length=25&search[value]=sherlock&search[regex]=false&movies=true&shows=true&documentaries=true&rating=netflix&_=1451768717982'
print requests.get(url).text

但是如果我将 url 输入浏览器，它会显示我的 json 信息。我在调试时确实注意到浏览器必须安装插件篡改数据才能查看 json。如果浏览器没有该插件，则会出现空白网页。所以，我的理论是它必须在没有处理 http 请求的情况下做一些事情，但我不知道从这里去哪里。

任何帮助都会很棒。

您需要打开一个 session ，访问主页以获取cookie设置，然后向“processing_us.php”发出XHR请求:

url = "http://www.allflicks.net/wp-content/themes/responsive/processing/processing_us.php?draw=5&columns[0][data]=box_art&columns[0][name]=&columns[0][searchable]=true&columns[0][orderable]=false&columns[0][search][value]=&columns[0][search][regex]=false&columns[1][data]=title&columns[1][name]=&columns[1][searchable]=true&columns[1][orderable]=true&columns[1][search][value]=&columns[1][search][regex]=false&columns[2][data]=year&columns[2][name]=&columns[2][searchable]=true&columns[2][orderable]=true&columns[2][search][value]=&columns[2][search][regex]=false&columns[3][data]=genre&columns[3][name]=&columns[3][searchable]=true&columns[3][orderable]=true&columns[3][search][value]=&columns[3][search][regex]=false&columns[4][data]=rating&columns[4][name]=&columns[4][searchable]=true&columns[4][orderable]=true&columns[4][search][value]=&columns[4][search][regex]=false&columns[5][data]=available&columns[5][name]=&columns[5][searchable]=true&columns[5][orderable]=true&columns[5][search][value]=&columns[5][search][regex]=false&columns[6][data]=director&columns[6][name]=&columns[6][searchable]=true&columns[6][orderable]=true&columns[6][search][value]=&columns[6][search][regex]=false&columns[7][data]=cast&columns[7][name]=&columns[7][searchable]=true&columns[7][orderable]=true&columns[7][search][value]=&columns[7][search][regex]=false&order[0][column]=5&order[0][dir]=desc&start=0&length=25&search[value]=sherlock&search[regex]=false&movies=true&shows=true&documentaries=true&rating=netflix&_=1451768717982"
with requests.Session() as session:
    session.headers = {"User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36"}
    session.get("http://www.allflicks.net/")

    response = session.get(url, headers={"Accept" : "application/json, text/javascript, */*; q=0.01", 
                                         "X-Requested-With": "XMLHttpRequest", 
                                         "Referer": "http://www.allflicks.net/", 
                                         "Host": "www.allflicks.net"})
    print(response.json())
