Unix命令行CURL等效于CURL

Question

以下片段来自“http://pdfx.cs.man.ac.uk/usage”。这个非常棒的工具，它将PDF中的科学论文转换为xml。

curl --data-binary @"/path/to/my.pdf" 
    -H "Content-Type: application/pdf" 
    -L "http://pdfx.cs.man.ac.uk" 

此代码是unix命令行代码，我希望它的PHP版本。我曾尝试

$pdfFile = fopen('jucs_18_05_0623_0649_hasan.pdf', 'r'); 
$fileSize = filesize ('jucs_18_05_0623_0649_hasan.pdf'); 
$url="http://pdfx.cs.man.ac.uk"; 
$ch=curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 
curl_setopt($ch, CURLOPT_TIMEOUT, 100); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_PUT, true); 
curl_setopt($ch, CURLOPT_INFILE, $pdfFile); 
curl_setopt($ch, CURLOPT_INFILESIZE, $fileSize); 
curl_setopt($ch, CURLOPT_VERBOSE, true); 

$fp = fopen("test.xml", "w"); 
curl_setopt($ch, CURLOPT_FILE, $fp); 

if (! $res = curl_exec($ch)) 
    echo "Error: ".curl_error($ch); 
else { 
    echo "Success"; 
} 
curl_close($ch); 

的问题是输出到的test.xml是索引文件的HTML代码，而不是提供物品的转换XML版本。

感谢放没有必要的。内容长度需要。

<?php 
$pdfFile = fopen('1.pdf', 'r'); 
$fileSize = filesize ('1.pdf'); 
$url="http://pdfx.cs.man.ac.uk"; 
$ch=curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 
curl_setopt($ch, CURLOPT_TIMEOUT, 100); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/pdf","Content-length: ".$fileSize)); 
curl_setopt($ch, CURLOPT_INFILE, $pdfFile); 
curl_setopt($ch, CURLOPT_INFILESIZE, $fileSize); 
curl_setopt($ch, CURLOPT_VERBOSE, true); 

$fp = fopen("test.xml", "w"); 
curl_setopt($ch, CURLOPT_FILE, $fp); 

if (! $res = curl_exec($ch)) 
    echo "Error: ".curl_error($ch); 
else { 
    echo "Success"; 
} 
curl_close($ch); 
?>
