如何处理移动设备发送的图像？ [英] How to handle images sent by a mobile device?

问题描述

我的同行正在开发一个iPhone应用程序，允许用户通过我的API在我的网站上发布图片。我正在构建将接受和处理图像的API的一部分。

手机开发人员正在发送这样的头文件：

  Content-Disposition：form-data; NAME = photo_1; filename =photo_1.jpg
 Content-Type：application / octet-stream 
  

寻找发送的图像，这是正常的HTML表单相同的方法？我应该寻找$ _FILES吗？

或者，使用PHP，我将如何找到他的图片？

解决方案

不显示它是通过一个表单发送，即< form enctype = multipart / form-data> 和< input type =file> ，所以 $ _ FILES 数组将不会被填充。 >

您可能需要阅读：

  $ HTTP_RAW_POST_DATA 
  

或do：



  $ rawPost = file_get_contents（php：// input）; 
  

从 manual ：



php：// input允许你从请求体中读取原始的
数据，如果是
的POST请求，它最好是
$ HTTP_RAW_POST_DATA，因为它不包含
取决于特殊的php.ini指令
此外，对于
$ HTTP_RAW_POST_DATA不是p在默认情况下使用
，这是一个潜在的更少的
内存密集型替代
激活
always_populate_raw_post_data。
php：//输入不可用于
enctype =multipart / form-data。

A peer of mine is developing an iPhone application that will allow users to post images on my site via my API. I am building the part of the API that will accept and process the images.

The mobile developer is sending headers like such:

Content-Disposition: form-data; name="photo_1"; filename="photo_1.jpg"
    Content-Type: application/octet-stream

When looking for the images sent, is it the same method as with normal HTML forms? Should I look for $_FILES?

Or, using PHP, how would I find his image?

解决方案

Doesn't appear it's being sent via a form, i.e., <form enctype=multipart/form-data"> and <input type="file">, so the $_FILES array won't be populated.

You'll probably need to read:

$HTTP_RAW_POST_DATA

or do:

$rawPost = file_get_contents("php://input");

From the manual:

php://input allows you to read raw data from the request body. In case of POST requests, it preferrable to $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".
