我试图通过客户端卷曲应用程序发送本地文件。我发现了一些使用表单中文件的例子。就我而言,我没有表格,只有本地文件。
$fileName = $_SERVER["DOCUMENT_ROOT"]."/www/images/test.pdf";
if(!file_exists($fileName)) {
$out['status'] = 'error';
$out['message'] = 'File not found.';
exit(json_encode($out));
}
$data = array('name' => 'Foo', 'file' => '@'.$fileName);
$cURL = curl_init("http://myapi/upload-images");
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
curl_setopt($cURL, CURLOPT_POST, 1);
curl_setopt($cURL, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($cURL);
$error = curl_error($cURL);
curl_close($cURL);
die($response);
有了这个,我没有错误,但在服务器中$ _POST和$ _SERVER数组是空的。
我试过了,这次在发送之前创建了一个Curl文件:
// Mime type of file
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$finfo = finfo_file($finfo, $fileName);
$cFile = new CURLFile($fileName, $finfo, "file");
//var_dump($cFile);
//CURLFile Object
//(
// [name] => C:/.../test.pdf
// [mime] => application/pdf
// [postname] => file
// )
$cURL = curl_init("http://myapi/upload-images");
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
curl_setopt($cURL, CURLOPT_POST, true);
curl_setopt($cURL, CURLOPT_POSTFIELDS,
array(
'file' => $cFile
));
$response = curl_exec($cURL);
curl_close($cURL);
die($response);
相同的回应。 $ _FILES是空的。
答案 0 :(得分:3)
最后我找到了问题的原因。包含文件数据的数组必须具有filedata和filename密钥。
我们可以在文件名之前传递'@'并使用完整路径,但不推荐使用此选项。
$data = array( "filedata" => '@'.$fileName, "filename" => basename($fileName));
在这种情况下,我添加了一个Curl对象:
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$finfo = finfo_file($finfo, $fileName);
$cFile = new CURLFile($fileName, $finfo, basename($fileName));
$data = array( "filedata" => $cFile, "filename" => $cFile->postname);
完整的代码是:
$fileName = $_SERVER["DOCUMENT_ROOT"]."/www/images/test.pdf";
$fileSize = filesize($fileName);
if(!file_exists($fileName)) {
$out['status'] = 'error';
$out['message'] = 'File not found.';
exit(json_encode($out));
}
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$finfo = finfo_file($finfo, $fileName);
$cFile = new CURLFile($fileName, $finfo, basename($fileName));
$data = array( "filedata" => $cFile, "filename" => $cFile->postname);
$cURL = curl_init("http://myapi/upload-images")
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
// This is not mandatory, but is a good practice.
curl_setopt($cURL, CURLOPT_HTTPHEADER,
array(
'Content-Type: multipart/form-data'
)
);
curl_setopt($cURL, CURLOPT_POST, true);
curl_setopt($cURL, CURLOPT_POSTFIELDS, $data);
curl_setopt($cURL, CURLOPT_INFILESIZE, $fileSize);
$response = curl_exec($cURL);
curl_close($cURL);
die($response);
