以编码形式获取卷曲响应

Question

我正在使用 curl 来获取半径内的 Zipcode，我为此编写了 curl，它在 Shell 中运行良好，但是当我在 PHP 中转换它时，我得到了编码响应。我的代码如下

php代码是

$headers = array(
    'Referer:http://www.freemaptools.com/find-zip-codes-inside-radius.htm',
    'User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.94 Safari/537.36',
    'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'Accept-Encoding:gzip, deflate',
    'Accept-Language:en-US,en;q=0.5',
    'Connection:keep-alive',
    'Pragma:no-cache',
    'Cache-Control:no-cache',
    'Origin:http://www.freemaptools.com',
    'Content-Type:text/plain; charset=UTF-8'        
);


$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, 'http://www.freemaptools.com/ajax/get-all-zip-codes-inside.php?radius=50&lat=36.7017377&lng=-95.87759640000002&rn=8523');
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl_connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_handle, CURLOPT_HEADER, 1);
curl_setopt($curl_handle, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl_handle, CURLOPT_COOKIE, " __utma=126142042.1539287389.1412828292.1412828292.1412828292.1; __utmb=126142042.1.10.1412828292; __utmc=126142042; __utmz=126142042.1412828292.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utmt=1");


$buffer = curl_exec($curl_handle);


curl_close($curl_handle);


echo '<pre>'; print_r($buffer);

响应类似于

请帮助我的代码有什么问题，我们将不胜感激。

Answer 1

您将获得与您的 shell 脚本中相同的输出：

$headers = array(
    'Referer:http://www.freemaptools.com/find-zip-codes-inside-radius.htm',
    'User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.94 Safari/537.36',
    'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'Accept-Language:en-US,en;q=0.5',
    'Connection:keep-alive',
    'Pragma:no-cache',
    'Cache-Control:no-cache',
    'Origin:http://www.freemaptools.com',
    'Content-Type:text/plain; charset=UTF-8'    
);

$curl_handle = curl_init();
curl_setopt($curl_handle, CURLOPT_URL, 'http://www.freemaptools.com/ajax/get-all-zip-codes-inside.php?radius=50&lat=36.7017377&lng=-95.87759640000002&rn=8523');
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($curl_handle, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_handle, CURLOPT_HEADER, 1); 
curl_setopt($curl_handle, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl_handle, CURLOPT_COOKIE, " __utma=126142042.1539287389.1412828292.1412828292.1412828292.1; __utmb=126142042.1.10.1412828292; __utmc=126142042; __utmz=126142042.1412828292.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utmt=1");

$buffer = curl_exec($curl_handle);

$header_size = curl_getinfo($curl_handle, CURLINFO_HEADER_SIZE);
$body = substr($buffer, $header_size);

curl_close($curl_handle);

$body = strtr($body,array("<"=>"&lt;","&"=>"&amp;")); // for displaying html tags
echo($body);

在您的代码中，您也没有在结束时关闭“pre”标签，

$curl_connection

应该是

$curl_handle

Answer 2

添加

curl_setopt($curl_handle, CURLOPT_ENCODING, "gzip");

并将其设置为 0，这样您就不会返回 http 标头

curl_setopt($curl_handle, CURLOPT_HEADER, 0);

您告诉服务器您同意在可能的情况下使用Accept-Encoding:gzip, 接收压缩数据

结果将是响应的 HTTP 标头（如果 CURLOPT_HEADER = 0，则不存在）+ XML

<markers><marker zipcode="67333" lat="37.061924" lng="-95.875119" 
city="CANEY" county="MONTGOMERY" state="KS" timezone="6" /> and so on

当然你的浏览器不会显示它。制作echo hmltentities($buffer);（在这种情况下不需要pre），你会看到它。
