Curl PHP文件上传 [英] Curl PHP File Upload

问题描述

嘿，试图使用curl发布文件，一切都很好。我有一个问题。我不能在我的post_file（）函数之外声明我的文件。

Hey, trying to post a file using curl and all is working great. I have one problem. I can't declare my file outside of my post_file() function. I call this function in my application many times so want it to be reusable.

这样就可以工作了：

function call_me(){
    $file_path = "/home/myfile.mov";
    $url = "http://myurl.com";
    $this->post_file($url, $file_path);
}
function post_file($url, $file_path){
    $data['Filedata'] = "@".$file_path;
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
    $response = curl_exec($ch);
    return $response;
}

但这不会：

function call_me(){
    $file_path = "/home/myfile.mov";
    $url = "http://myurl.com";
    $data['Filedata'] = "@".$file_path;
    $this->post_file($url, $data);
}
function post_file($url, $data){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
    $response = curl_exec($ch);
    return $response;
}

任何想法？干杯。

推荐答案

我真的没有看到两个代码集之间的差异（重新可用性）。 ＃2 的唯一好处是你传递了整个 $ data 对象 - 如果这是一个好处，你的CURL post的安全问题...所以这真的比每次创建一个新的 $ data 对象（每＃1 ）？使用函数名 post_file ，预期行为将是＃1 - 将单个文件发布到URL，而代码＃2 可以被利用/用于其他类型的东西。 ＃1的可用性增强可能是：

I don't really see a difference (for re-usability) between the two code sets. The only benefit of #2, is you're passing in the whole $data object - if that's a benefit at all... it leads to security issues with your CURL post... so is this really better than creating a new $data object each time (per #1)? With the function name post_file the expected behaviour would be per #1 - post a single file to the URL, while code #2 could be exploited/used for other kinds of things. Perhaps a usability enhancement of #1 would be:

function post_files($url,$files) {
    //Post 1-n files, each element of $files array assumed to be absolute
    // path to a file.  $files can be array (multiple) or string (one file).
    // Data will be posted in a series of POST vars named $file0, $file1...
    // $fileN
    $data=array();
    if (!is_array($files)) {
      //Convert to array
      $files[]=$files;
    }
    $n=sizeof($files);
    for ($i=0;$i<$n;$i++) {
      $data['file'+$i]="@".$files[$i];
    }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
    $response = curl_exec($ch);
    return $response;
}

至于为什么它不适合你现在 - 我猜在某处有错别字。这个代码是否完全复制，或者是你为我们改写？在 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ data）; 行之前尝试 print_r（$ data）;

As to why it's not working for you right now - I'm guessing there's a typo in there somewhere. Is this code copied exactly or are you paraphrasing for us? Try a print_r($data); just before the curl_setopt($ch, CURLOPT_POSTFIELDS, $data); line.

函数无法知道对象是在函数（＃1 ）中创建还是传入（ 2 ）。

There's no way for a function to know if the object was created within the function (#1) or passed in (#2).
