PUT vs. POST for Uploading Files - RESTful API to be Built Using Zend Framework

problem ：

I'm building a RESTful API using Zend Framework via the Zend_Rest_Route. I'm passing Zend_Rest_Route Use Zend Framework Construct a RESTful API.For uploading of files, should I use PUT or POST to handle the process? For uploaded files , I should use PUT still POST To handle the process ？I'm trying to be as consistent as possible with the definition of the REST verbs. I try to be as close as possible to REST The definitions of verbs are consistent .Please refer to: PUT or POST: The REST of the Story . see also ： PUT or POST： The rest of the story .

The way I understand this is that I should use PUT if and only if I'm updating the full content of the specified resource. My understanding is that , If and only if I update the entire content of the specified resource , I should use PUT.I'll have to know the exact URL to use PUT. I must know how to use PUT Exact URL.On the other hand, I should use POST if I'm sending a command to the server to create a subordinate of the specified resource, using some server-side algorithm. On the other hand , If I use some server-side algorithms to send commands to the server to create children of a specified resource , I should use POST.

Let's assume this is a REST API for uploading images. Suppose this is a for uploading images REST API.Does that mean I should use POST if the server is to manipulate the image file (ie create thumbnail, resize, etc); Does this mean that if the server wants to manipulate image files （ That is, create thumbnails 、 Resize, etc ）, I should use POST Do you ？and use PUT if I just want to save the raw image file to the server? If I just want to save the original image file to the server , Please use PUT？

If I use PUT to handle a file upload, should the process be as follows: If I use PUT To handle file uploads , The process should be as follows ：

1. The user sends a GET request to retrieve the specific URL to upload the file by PUT. The user sends GET Request to retrieve a specific URL In order to pass the PUT Upload files .
2. Then the user sends a PUT request to that URL. Then the user sends the URL send out PUT request .
   The file being uploaded is raw - exactly the one the user uploaded. The uploaded file is the original file - It is the file uploaded by the user .

I'm quite new to this stuff; I am very strange to this thing ;so hopefully I'm making sense here... So I hope I'm meaningful here ......
