Question

在通过邮递员感觉舒适测试Box API后，我现在正在努力运行来自php文件的curl请求。我可以运行其中一些，但我无法弄清楚如何转换https://developers.box.com/docs/#files-upload-a-file中描述的文件上传请求。上述链接提供的示例请求是：

curl https://upload.box.com/api/2.0/files/content \
  -H "Authorization: Bearer ACCESS_TOKEN" -X POST \
  -F attributes='{"name":"tigers.jpeg", "parent":{"id":"11446498"}}' \
  -F file=@myfile.jpg

我写的是：

<?php
$folder_id = "2934811551"; //fake
$accessToken = "QxYtOeSUCdlu5PwMwxUJSD5BeMP9AaoZ"; //fake
$file_out = "\home\box\upload.json";  //store the JSON response
$file_up = "\home\box\uploadfile.txt"; //file to upload

$curl_url = 'https://upload.box.com/api/2.0/files/content';

$params = array('name' => '@' . $file_up,
                'parent' => array('id' => $folder_id)
               );
$params_json = json_encode($params);


//execute CURL 
$fp = fopen($file_out, "w"); //output file

$ch = curl_init();
$options = array(
         CURLOPT_URL            => $curl_url,           
         CURLOPT_RETURNTRANSFER => true,
         CURLOPT_HTTPHEADER     => array("Authorization: Bearer " . $accessToken),          
         CURLOPT_POST           => true,
         CURLOPT_POSTFIELDS     => $params_json,
         CURLOPT_VERBOSE        => true,
         CURLOPT_FILE           => $fp,     
        );
curl_setopt_array($ch, $options);
$result = curl_exec($ch);

print_r (curl_getinfo($ch));
echo curl_error($ch);

curl_close($ch);

fclose($fp);

?>

结果是：

如果我添加echo $params_json;，我会：

{"name":"@\\home\\dianna\\box\\uploadfile.txt","parent":{"id":"2934811551"}}

如果不是CURLOPT_POSTFIELDS => $params_json,处的jkson编码字符串，而是使用CURLOPT_POSTFIELDS => $params,传递数组，我会得到failed creating formpost data。如果此时我编辑$ file_up var来存储要上传的文件的相对url（$file_up = "uploadfile.txt";这个文件和我的php文件在同一文件夹中），我的php文件的输出变为：

现在将content-Type设置为multipart / form-data，但响应仍为400。我已经在这里阅读了关于这个主题的所有答案，以及关于curl的PHP页面手册页，但这是我已经得到的...（顺便说一句，如果它有助于我使用PHP 5.3.3）

任何帮助将不胜感激！

Answer 1

看看这个。我已经成功使用它并发现它是box-api和php的最佳框架https://github.com/golchha21/BoxPHPAPI

Answer 2

这是我使用方框API上传图片的方式。

$attributes = array('name'=>time().'.jpg','parent'=>array('id'=>$parent_id));

$params = array('attributes' => json_encode($attributes), 'file' => "@".realpath($filename));
$headers = array("Authorization: Bearer ".$accesstoken);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
$data = curl_exec($ch); 
curl_close($ch);

Answer 3

上周我花了很多时间在同一个问题上挣扎。这里发布的另外两个答案对我们不起作用。我也找不到任何与PHP相关的建议。最后决定调用运行curl的外部unix脚本：

#!/bin/bash
#upload.sh
ACCESS_TOKEN="$1"
FOLDER_ID="$2"
FILE="$3"
HEADER="Authorization: Bearer $ACCESS_TOKEN"

STATUS=`curl "https://upload.box.com/api/2.0/files/content" -H "$HEADER" -F parent_id=${FOLDER_ID} -F filename=@${FILE} -i -s | grep HTTP/1.1 | tail -1 | awk {'print $2'}` > /dev/null

if [ $STATUS == 201 ]
then
    #OK
else
    #Upload failed
fi

PHP中的调用格式为：

$result = shell_exec("upload.sh $box_token $folder_id $file_name");

不满意，但确实有效。只有建议我可以考虑为什么PHP CURL不起作用是管道中的东西弄乱了令牌。这是在PHP 5.5.15。
