如何使用curl下载IP2Location数据库

如何解决如何使用curl下载IP2Location数据库

我正在尝试使用他们提供的curl命令从IP2Location下载数据库。我已经注册，所以我有一个有效的令牌。他们给出的命令是

    curl -o {LOCAL_FILE_NAME} "https://www.ip2location.com/download?token={DOWNLOAD_TOKEN}&file={DATABASE_CODE}"

这是我使用的代码，除了令牌：

    $curl = curl_init();
    curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($curl,CURLOPT_URL,"https://www.ip2location.com/download?token={mytoken}&file={DB1LITEBIN}");

    $dbfile = curl_exec($curl);

    if (curl_errno($curl)) {
     echo 'err '.curl_errno($curl);
    }                  

    curl_close($curl);

    $file = 'db_download.bin';  
    $mode = 'w';

     if (($fp = fopen($file,$mode))) {    
       $fout = fwrite($fp,$dbfile);
       fclose($fp);  
    }  

脚本运行无错误，但下载的文件只是其站点的未找到页面。如果在浏览器中使用该网址，则会得到找不到相同页面的信息。有人可以指出我的错误吗？

解决方法

请尝试以下方法。请注意，您将下载一个包含bin文件的zip文件。

<?php

//The resource that we want to download.
$fileUrl = 'https://www.ip2location.com/download?token=XXXXXXXXXX&file=DB1LITEBIN';

//The path & filename to save to.
$saveTo = 'db_download.zip';

//Open file handler.
$fp = fopen($saveTo,'w+');

//If $fp is FALSE,something went wrong.
if($fp === false){
    throw new Exception('Could not open: ' . $saveTo);
}

//Create a cURL handle.
$ch = curl_init($fileUrl);

//Pass our file handle to cURL.
curl_setopt($ch,CURLOPT_FILE,$fp);

//Timeout if the file doesn't download after 20 seconds.
curl_setopt($ch,CURLOPT_TIMEOUT,20);

curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);

//Execute the request.
curl_exec($ch);

//If there was an error,throw an Exception
if(curl_errno($ch)){
    throw new Exception(curl_error($ch));
}

//Get the HTTP status code.
$statusCode = curl_getinfo($ch,CURLINFO_HTTP_CODE);

//Close the cURL handler.
curl_close($ch);

//Close the file handler.
fclose($fp);

if($statusCode == 200){
    echo 'Downloaded!';
} else{
    echo "Status Code: " . $statusCode;
}
