使用CURL和PHP的麻烦，通过代理获取Google搜索结果 [英] Having Trouble Using CURL and PHP to Get Google Search Results Through a Proxy

问题描述

此脚本在获取google.com时可正常运行，但不能通过google.com/search?q=test运行。当我不使用CURLOPT_FOLLOWLOCATION，我得到一个302移动。当我使用它，我得到一个页面，要求我输入一个验证码。我试过几个不同的美国代理，并改变了用户代理字符串。有没有什么我在这里失踪？

This script works fine when getting google.com but not with google.com/search?q=test. When I don't use CURLOPT_FOLLOWLOCATION, I get a 302 Moved. When I do use it, I get a page asking me to input a captcha. I've tried several different U.S. based proxies and have varied the user agent string. Is there something I'm missing here?

function my_fetch($url,$proxy,$user_agent='Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.8) Gecko/2009032609 Firefox/3.0.8') 
{ 
    $ch = curl_init(); 
    curl_setopt ($ch, CURLOPT_URL, $url); 
    curl_setopt ($ch, CURLOPT_PROXY, $proxy);
    curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent); 
    curl_setopt ($ch, CURLOPT_HEADER, 0);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_REFERER, 'http://www.google.com/'); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

    curl_setopt ($ch, CURLOPT_TIMEOUT, 20);
    $result = curl_exec ($ch); 
    curl_close ($ch); 
    return $result; 
}

$url = 'http://www.google.com/search?q=test';

$proxy = '152.26.53.4:80';
echo my_fetch($url,$proxy);

请勿回应建议使用API​​。

Please don't respond with suggestions to use the API instead. The API is not sufficient for my needs.

推荐答案

您可以尝试使用PhantomJS：

You can try to do that with PhantomJS:

var page = require("webpage").create();
var homePage = "http://www.google.com/";

page.open(homePage);
page.onLoadFinished = function(status) {
 var url = page.url;

console.log("Status:  " + status);
console.log("Loaded:  " + url);


page.includeJs("http://code.jquery.com/jquery-1.8.3.min.js", function() {
  console.log("Loaded jQuery!");
  page.evaluate(function() {
    var searchBox = $(".lst");
    var searchForm = $("form");

    searchBox.val("your query");
    searchForm.submit();
  });
});

window.setTimeout(
        function () {
          page.render( 'google.png' );
          phantom.exit(0);
        },
        1000 // wait 5,000ms (5s)
      );


};
