上传文件时发生错误“创建表单数据失败” [英] Curl error when uploading file "failed creating formpost data"

问题描述

当我尝试使用php和curl上传文件时，会出现创建表单数据失败的错误。我知道文件路径不正确时会出现错误

When I trying to upload a file with php and curl, an error occurs "failed creating formpost data". I know that error occur when file path incorrect

test.php
...
$postcontent['files'] = '@test.jpg';
...

test.php和test.jpg。但如果我改变路径到物理路径，代码运行良好

test.php and test.jpg in the same folder. But if I change path to physic path, code run well

test.php
...
$postcontent['files'] = '@F:\xampp\htdocs\upload\test.jpg';
...

推荐答案

一个绝对路径，就像你在第二个例子中所做的一样。

Try to always use an absolute path, like you did in your second example, which works.

当然，你不想硬编码路径，因此您需要使用：

Of course, you do not want to hard-code that physical path, so you will want to use either :

• dirname（__ FILE __）获取包含写入文件的目录的路径


• 或者，使用PHP> = 5.3： __ DIR __ 完全相同的路径。

• dirname(__FILE__) to get the path to the directory that contains the file in which this is written
• Or, with PHP >= 5.3 : __DIR__ which gives exactly the same path.

所以，在你的情况下，你可能会使用类似： / p>

So, in your case, you'd probably use something like :

$postcontent['files'] = '@' . __DIR__ . '/test.jpg';

5.3：

$postcontent['files'] = '@' . dirname(__FILE__) . '/test.jpg';
