我正在尝试通过 POSTMAN 通过 BOX API 下载图像文件。文件编号为 6917417032

我的代码是： https ://api.box.com/2.0/files/6917417032/content 我在标题中指定了授权码

文档状态：返回 如果文件可供下载，则响应将是 302 Found 到 dl.boxcloud.com 上的 URL。客户端需要遵循重定向才能实际下载文件。除非文件 ID 无效或用户无权访问，否则返回文件的原始数据。

我在 POSTMAN 中的回复是“200，OK” dl.boxcloud.com 没有 302。POSTMAN 还会预览空白缩略图。如果我对 word 文档执行相同的操作，POSTMAN 会显示文档中的下一个。我期待的是一个文件下载对话框，或者上一段中描述的 url。

注意，curl 示例代码和响应也不同于描述返回的段落：

方法

获取 /files/{文件 ID}/内容

示例请求

curl -L https://api.box.com/2.0/files/FILE_ID/content **强文本** -H "授权：Bearer ACCESS_TOKEN"

示例响应我刚刚下载的文本文件的原始文本（所以下载成功）

有两件事混淆了这里发生的事情：

  1. POSTMAN 跟踪 GET 请求的重定向，但不提供有关请求历史记录的信息（例如，如果我说 GET URL1 并被重定向到 GET URL2，它只会告诉我我原来的 GET URL1，即使它提供了 GET URL2 的结果）

  2. 文档中的 cURL 示例包含一个 -L 标志，它告诉 cURL 遵循重定向。cURL 不以提供明确要求之外的任何信息而闻名，这是另一种情况。

如果您想查看实际发生的情况，可以通过添加 'v 标志将 cURL 置于详细模式并查看发生的所有情况，例如：

curl -v -L https://api.box.com/2.0/files/FILE_ID/content -H "Authorization: Bearer TOKEN"

解决方案

获取 box.com 文件的直接下载链接

您需要为此使用 Curl

<?php


    $token = "<accsess_token>"; 

//setup the request, you can also use CURLOPT_URL
$ch = curl_init('https://api.box.com/2.0/files/FILE_ID_HERE/content');//Enter File id

// Returns the data/output as a string instead of raw data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//Set your auth headers
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
   'Content-Type: application/json',
   'Authorization: Bearer ' . $token
   ));

// get stringified data/output. See CURLOPT_RETURNTRANSFER
$response = curl_exec($ch);

// get info about the request
$info = curl_getinfo($ch);
// print_r($info->getBody());
// $header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
// $header = substr($response, 0, $header_size);
// $body = substr($response, $header_size);
echo '<pre>'; print_r($info['redirect_url']);
// close curl resource to free up system resources
curl_close($ch);
?>
