cURL没有将文件发送到API CALL [英] cURL not sending file to API CALL

问题描述

我正在构建一个通过API运行的移动站点，并拥有一个API CALL处理程序类，该类可以执行我从主函数文件运行的所有调用.

I am building a mobile site that runs from an API and have an API CALL handler class which does all the calls which I run from a primary functions file.

这里的问题是我的文件未发送到API，并且无法识别什么是文件，并返回文件不存在的错误.

The issue here is my files are not being sent through to the API and it's not recognising what is a file and is returning a file not present error.

注意:问题已解决且工作代码如下

以下代码:

表格

<form id="uploadPhoto" action="<?php uploadStreamPhoto(); ?>" method="post" enctype="multipart/form-data">
    <input type="file" name="streamPhotoUpload" id="streamPhotoUpload" />
    <input type="submit" name="streamPhotoUploadSubmit" id="streamPhotoUploadSubmit" value="Upload" />
</form>

上传功能

function uploadStreamPhoto()
{

    if(isset($_POST['streamPhotoUploadSubmit']))
    {

        $apiHandler = new APIHandler();
        $result = $apiHandler->uploadStreamPhoto($_FILES['streamPhotoUpload']['tmp_name']);
        $json = json_decode($result);
        var_dump($json);

        //header('Location: '.BASE_URL.'stream-upload-preview');

    }

}

处理方法

public function uploadStreamPhoto($file)
{

    $result = $this->request(API_URL_ADD_PHOTO, array(
    'accessToken' => $this->accessToken,
    'file' => "@$file;filename=".time().".jpg",
    'photoName' => time(),
    'albumName' => 'Stream'
    )); 

    return $result;

}

CURL请求方法

/**
* Creates a curl request with the information passed in post fields
*
* @access private
* @param string $url
* @param array $postFields
* @return string
**/
private function request($url, $postFields = array())
{

    $curl = curl_init();

    //Check the SSL Matches the host
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);

    if($this->debug == true)
    {

        //Prevent curl from verifying the certificate
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);

    }

    //Set the URL to call
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HEADER, 0);

    //Set the results to be returned
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    //Set the curl request as a post
    curl_setopt($curl, CURLOPT_POST, 1); 

    //Set the post fields
    curl_setopt($curl, CURLOPT_POSTFIELDS, $postFields); 

    $result = curl_exec($curl);

    if($result === false)
    {

        $result = 'Curl error: '.curl_error($curl);

    }

    curl_close($curl);

    return $result;

}

推荐答案

好，我发现了问题所在，希望该解决方案将对很多不想更改代码方式的人有所帮助.别人.

OK I have found out what the issue was, hopefully the solution will help a lot of people who don't want to change how their code is in lieu of someone elses.

cURL没有检测到它应该以多部分形式发送，因此它以默认编码发送帖子，这意味着另一端没有收到$ _FILES变量.

cURL was not detecting that it was supposed to send this form as a multipart so it was sending the post as a default encoding meaning the other end wasn't receiving the $_FILES variable.

要解决此问题，您需要将postdata作为数组提供，我正在创建要发送的字符串，我已经删除了它，并为CURLOPT_POSTFIELDS提供了一个数组.

To solve this you need to give the postdata as an array, I was creating the string for the send, I have removed this and am giving the CURLOPT_POSTFIELDS an array.

使用cURL直接从表单上载时，另一个重要的事情是将文件的信息与实际文件一起包括在内.

Another important thing when uploading directly from a form using cURL is to include the information for your file along with the actual file.

我的API调用处理程序现在创建数组如下:

My API Call handler now created the array as follows:

public function uploadStreamPhoto($file)
{

    $result = $this->request(API_URL_ADD_PHOTO, array(
    'accessToken' => $this->accessToken,
    'file' => "@$file;filename=".time().".jpg",
    'photoName' => time(),
    'albumName' => 'Stream'
    )); 

    return $result;

}

请注意，$ file变量为$ _FILES ['tmp_name']，然后还必须定义文件名.我将使用解决方案来更新问题.

Take note that the $file variable is $_FILES['tmp_name'] You then also have to define the file name. I will be updating the question with the solution.
