CURL调用未将文件从本地上传到远程服务器PHP [英] CURL call not uploading the file from local to remote server PHP
问题描述
我有以下CURL调用，它将把本地文本文件上传到另一个位置，到目前为止，仅在本地主机中（即，出于测试目的，一旦成功运行，我将推送服务器位置）。但是问题是本地文本文件没有被发布。有什么方法可以发布文件。
Hi I am having the following CURL call which will upload the local text file to another location, as of now in localhost only (ie. for testing purpose, once it runs successfully I will push the server location). But the problem is the local text file is not getting posted. Is there any way to POST the file.
注意-我不想通过 file_get_contents 或 FTP 上传。甚至我提到了其他问题，但都没有解决我的问题。
NOTE - I dont want to do this by file_get_contents or FTP upload. Even I referenced other question but didn't solve my problem.
<?php
/* CURL Initilization */
$curl = curl_init();
/* Setting the remove URL */
curl_setopt($curl, CURLOPT_URL, 'http://127.0.0.1/php_training/get_curl_call.php');
/* I want to return the transfer and store in data instead of outputing on screen */
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
/* To upload safely */
curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
/* Enable sending the data as POST data */
curl_setopt($curl, CURLOPT_POST, true);
/* Sending the data using @ is before 5.5, now I am using curl_file_create */
/* realpath - will get the absolute path of the .txt file */
curl_setopt($curl, CURLOPT_POSTFIELDS, array(
'log_file' => curl_file_create(realpath('websites.txt'))
)
);
/* Store the response of curl execution */
$response = curl_exec($curl);
print_r($response, curl_error($curl));
curl_close($curl);
以下是 get_curl_call.php
<?php
// $filename = $_POST['log_file'];
print_r($_POST);exit;
以下是 websites.txt 文件的内容

我无法纠正文件未上传的原因。
I am not able to rectify why the file is not getting uploaded. Any help really appreciated.
推荐答案
尝试以下代码，我已根据您的需要对其进行了更新。同样，当我们发布文件时，它不会像您一样使用 $ _ POST 显示，而是要查看文件，您需要打印 $ _ FILES
Try the following code, I have updated it according to your need. Also when we post a file it will not be displayed using $_POST as you are doing, instead to see files you need to print $_FILES
我尚未测试您的代码，但对我来说，这似乎还不错。您的主要错误是您正在使用 $ _ POST 打印上传文件。文件上传位于 $ _ FILES 数组中。尝试打印该文件。
I have not tested your code, but to me, it seems fine. Your major mistake is that you are printing the upload file using $_POST. File uploads are available in $_FILES array. Try to print that.
上传文件：（即使旧版本的PHP都兼容）
请注意，出于兼容性目的，当CURLFile不是可用（对于低于5.5的PHP）我使用过file_get_contents。
Upload file: (This is compatible even with older versions of PHP) Please note that, for compatibity purpose, when CURLFile is not available (for PHP less than 5.5) I have used file_get_contents.
<?php
$file = "websites.txt";
upload_with_compatibility($file);
function upload_with_compatibility($file){
if (version_compare(phpversion(), '5.5', '>=')) {
echo "Upload will be done using CURLFile\n";
upload($file); //CURL file upload using CURLFile for PHP v5.5 or greater
}else{
echo "Upload will be done without CURLFile\n";
compatibleUpload($file); //CURL file upload without CURLFile for PHP less than v5.5
}
}
//Upload file using CURLFile
function upload($file){
$target = "http://localhost:8888/upload_file.php";
$host = parse_url($target);
$cFile = new CURLFile($file,'text/plain', $file);
$data = array(
'log_file' => $cFile,
);
