如何使用curl下载IP2Location数据库

Question

我正试图使用他们提供的curl命令从IP2Location下载一个数据库。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}"

这是我正在使用的代码，除了我的代币：

$curl = curl_init();
curl_setopt($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);  
}  

脚本运行时没有错误，但下载的文件只是他们网站的未找到页面。如果我在浏览器中使用url，我会得到找不到的同一页面。有人能指出我的错误吗？

Answer 1

请尝试以下操作。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;
}

#!/bin/bash
fileUrl="https://www.ip2location.com/download?token=XXXXXXXXXX&file=DB1LITECVS"
saveTo="db_download.zip"
curl -o "$saveTo" -k "$fileUrl"
statusCode=$(curl -s -w "%{http_code}" -o /dev/null "$fileUrl")
if [ "$statusCode" == "200" ]; then
echo "Downloaded!"
else
echo "Status Code: $statusCode"
fi

添加curl_setopt($ch，CURLOPT_FOLLOWLOCATION，true(；它起作用了，谢谢
