无法通过php中的curl上传文件

我有一个HTML代码，允许我在服务器上成功上传文件

<form action="http://aa.bb.ccc.dd/xxx/upload.php" method="post" enctype="multipart/form-data">
        <label for="text">Campaign:</label>
        <input type="text" name="campaign" value="abcde" readonly="readonly"/><br/>
        <label for="file">Upload type:</label>
        <input type="text" name="filename" value="0.csv" readonly="readonly"/><br/>
        <label for="file">Filename:</label>
        <input type="file" name="file" id="file"/><br/>
        <input type="submit" name="submit" value="Submit" />
    </form>

结果也是1，但是当我签入服务器时，文件没有上传。我错过了什么？

任何帮助都将不胜感激

我对使用PHP“cURL”很感兴趣。这看起来是一个相当标准的要求

我看了一些“web上的cURL PHP示例”

事实上，使用你发布的代码，我看不出有什么不对劲

不管怎样，我使用了你的代码并创建了类似的脚本。唉，你没有发布你的“upload.php”脚本。我已经创建了一个PHP手册中提到的验证工具：

尽管此示例适用于“localhost”。我用一个“真正的”外部主机运行它，它运行得很好

使用PHP5.3.28在windows和Linux上的PHP5.3.18上进行测试

Html表单在“for”方面与标签有些混淆：

<form action="process_uploaded_file.php" method="post" enctype="multipart/form-data">
        <label for="text">Campaign:</label>
        <input type="text" name="campaign" value="abcde" readonly="readonly"/><br/>
        <label for="filetype">Upload type:</label>
        <input type="text" name="filetype" value="0.csv" readonly="readonly"/><br/>
        <label for="file">Filename:</label>
        <input type="file" name="file" id="file"/><br/>
        <input type="submit" name="submit" value="Submit" />
</form>

上载类型：


文件名：

卷曲脚本：

<?php
$target_url = 'http://localhost/testmysql/process_uploaded_file.php';
$full_path_to_source_file = __DIR__ .'/sourcefiles/testupload1.csv' ;
$post = array('campaign' => 'abcde', 'file'=>'@'. $full_path_to_source_file, 'filename' => 'curl1.csv');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);
var_dump($result);

您可以突出显示并整理您的代码吗，它似乎有重复的代码框。可以使用CURLOPT_SAFE_UPLOAD在PHP5.5中禁用文件上载的“@”符号（尽管默认情况下是允许的）。如果您已经使用了5.5，那么最好改用它。
<?php
$target_url = 'http://localhost/testmysql/process_uploaded_file.php';
$full_path_to_source_file = __DIR__ .'/sourcefiles/testupload1.csv' ;
$post = array('campaign' => 'abcde', 'file'=>'@'. $full_path_to_source_file, 'filename' => 'curl1.csv');

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);
var_dump($result);
