数据在表单发送时损坏，= \r\\\<br/>在每75个字符的数据中引入数据？ [英] Data gets corrupted on form send, =\r\n introduced in the data every 75 characters?

问题描述

我正在Google App Engine上进行Django nonrel的项目，虽然我有一种感觉，我的问题与这些直接无关。

我在一个模型中有一个隐藏的字段，定义如下：

  models.CharField（max_length = 400，null = True，blank = True，default ={}）
  

该字段旨在接收JSON数据来自我的管理员中的小部件，客户端的值会正确更改。

（正在发送的数据与我的问题无关 - 无论是字符串在该字段的值被损坏）

问题是 -
当我看到数据被传递到django保存功能，我看到每75个字符我得到数据字符串内的 = \r\\\
。这有效地打破了字符串，使我的数据无用。我不知道这是从哪里来的，或者是什么原因。

更有趣的点：

• 由于我使用GAE blobstore上传该表单中的文件，所以管理表单有 enctype ='multipart / form-data'
  
• 我正在使用 django-filetransfers 以方便使用blobstore


• 我已经检查了浏览器中出现的请求，出来的数据很干净


• Django将模型中的数据保存为UTF8

我没有发现任何远程接近我的问题在谷歌...

有没有人有解决方案？或者可能是从哪里开始寻找的方向？

解决方案

原来，问题是 Google App Engine中的此错误

我在这里找到我的解决方案：提交多部分/表单数据表单时，应用引擎中的编码问题

使用Andres Bossard中间件修复该问题已解决问题

I'm working on a project in Django nonrel, on Google App Engine, though I have a feeling my problem has nothing to do with either of these directly .

I have a hidden field in one of the models that is defined like so:

models.CharField(max_length=400, null=True, blank=True,default="{}")

The field is meant to receive JSON data from a widget in my admin, and in the client its value changes properly.

(Which data is being sent is irrelevant to my problem - whatever string is in the field value is being corrupted)

The problem is - when I look at the data as passed to the django save function , I see that every 75 characters I get =\r\n inside the data string. This effectively breaks the string, rendering my data useless. I have no idea where this is coming from, or what causes this.

More interesting points:

• The admin form has enctype='multipart/form-data', since I use GAE blobstore to upload a file in that form
• I'm using django-filetransfers to facilitate working with the blobstore
• I've checked the request going out of the browser, the data going out is clean
• Django saves the data in the model as UTF8

I haven't found anything remotely close to my problem on google...

Does anyone have a solution? Or maybe a direction on where to start looking?

解决方案

So it turns out the problem is a result of this bug in Google App Engine

I found my solution here: Encoding problem in app engine when submitting multipart/form-data forms

The problem was solved using Andres Bossard middleware fix in that thread
