PHP cURL: how to set body to binary data?
提问by Nocklas
I'm using an API that wants me to send a POST with the binary data from a file as the body of the request. How can I accomplish this using PHP cURL?
我正在使用一个 API，它希望我发送一个 POST，其中包含来自文件的二进制数据作为请求的正文。如何使用 PHP cURL 完成此操作？
The command line equivalent of what I'm trying to achieve is:
相当于我想要实现的命令行是：
curl --request POST --data-binary "@myimage.jpg" https://myapiurl

You can just set your body in CURLOPT_POSTFIELDS.
你可以把你的身体放在CURLOPT_POSTFIELDS.
Example:
例子：
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://url/url/url" );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, "body goes here" );
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/plain'));
$result=curl_exec ($ch);
Taken from here
取自这里
Of course, set your own header type, and just do file_get_contents('/path/to/file')for body.
当然，设置你自己的header类型，只file_get_contents('/path/to/file')为body做。

This can be done through CURLFile instance:
这可以通过 CURLFile 实例完成：
$uploadFilePath = __DIR__ . '/resource/file.txt';
if (!file_exists($uploadFilePath)) {
throw new Exception('File not found: ' . $uploadFilePath);
}
$uploadFileMimeType = mime_content_type($uploadFilePath);
$uploadFilePostKey = 'file';
$uploadFile = new CURLFile(
$uploadFilePath,
$uploadFileMimeType,
$uploadFilePostKey
);
$curlHandler = curl_init();
curl_setopt_array($curlHandler, [
CURLOPT_URL => 'https://postman-echo.com/post',
CURLOPT_RETURNTRANSFER => true,
/**
* Specify POST method
*/
CURLOPT_POST => true,
/**
* Specify array of form fields
*/
CURLOPT_POSTFIELDS => [
$uploadFilePostKey => $uploadFile,
],
]);
$response = curl_exec($curlHandler);
curl_close($curlHandler);
echo($response);

Try this:
尝试这个：
$postfields = array(
'upload_file' => '@'.$tmpFile
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url.'/instances');
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);//require php 5.6^
curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$postResult = curl_exec($ch);
if (curl_errno($ch)) {
print curl_error($ch);
}
curl_close($ch);

You need to provide appropriate header to send a POST with the binary data.
您需要提供适当的标头以发送带有二进制数据的 POST。
$header = array('Content-Type: multipart/form-data');
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($resource, CURLOPT_POSTFIELDS, $arr_containing_file);
Your $arr_containing_file can for example contain file as expected (I mean, you need to provide appropriate expected field by the API service).
例如，您的 $arr_ contains_file 可以包含预期的文件（我的意思是，您需要通过 API 服务提供适当的预期字段）。
$arr_containing_file = array('datafile' => '@inputfile.ext');
