python request.get()返回一个空字符串 [英] python requests.get() returns an empty string

问题描述

当我运行以下代码时，它返回一个空字符串

When I run the below code it returns an empty string

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放在浏览器中，它将显示我的json信息.我确实在调试时注意到，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，则会显示空白网页.因此，我的理论是它必须在不处理http请求的情况下做点什么，但是我不在这里.

but if I put the url in my browser it'll show my the json information. I did notice while debugging the browser must have the plugin tamper data installed to view the json. If a browser doesn't have the plug in a blank web page will appear. So, my theory is it has to do something with out the http request is being handed but I'm not where to go from here.

任何帮助都会很棒.

您需要打开

You need to open up a session, visit the main page to get the cookies set and then make the XHR request to "processing_us.php":

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())
