ASP.NET webAPI< - > Dojo上传者的响应格式错误 [英] ASP.NET webAPI <--> Dojo uploader response format is wrong

问题描述

我有使用dojo上传文档的问题。
我使用dojox / form / Uploader来上传一个文件，不支持模式。上传后，以特殊格式响应服务器。上传者只有在我发送时才有效：

i have a problem with uploading documents with dojo. I´m using the dojox/form/Uploader to upload a file withiframe mode. After uploading there is a response from the server in a special format. The uploader only works when i send it like this:

服务器：'{name：file.png，file：filename，type ：form-data}'

Server: '{"name":"file.png","file":"filename","type":"form-data"}'

但答案是：
客户端：'{\name \：\ .png \，\file\：\filename \，\type\：\form-data\}'

But the answer is: Client: "'{\"name\":\"file.png\",\"file\":\"filename\",\"type\":\"form-data\"}'"

所以我认为有两种可能的方法来解决这个问题：

So i think there are two possible ways to solve this problem:

A。修复它在客户端
B.修复它在服务器端

A. Fixing it on the client side B. Fixing it on the server side

我找不到一个解决方案B.我使用ASP.NET webAPI并创建这样的回复：

I could not find a solution for B. I´m using ASP.NET webAPI and create the reponse like that:

Dim msg = "<textarea>'{" + Chr(34) + "name" + Chr(34) + ":" + Chr(34) + fileName + Chr(34) + "," + Chr(34) + "file" + Chr(34) + ":" + Chr(34) + returnData.Item1 + Chr(34) + "," + Chr(34) + "type" + Chr(34) + ":" + Chr(34) + returnData.Item3 + Chr(34) + "}'</textarea>"
Dim response = Request.CreateResponse(Of String)(HttpStatusCode.Created, msg)
response.Content.Headers.ContentType = New MediaTypeHeaderValue("text/html")
Return response

看起来很奇怪，但答案必须由html标签包含，内容是json。

Looks weird but the answer has to be enclosed by a html tag, the content is json.

也许有一种方法可以告诉webAPI不要将这些额外的斜线放在响应中？
我放弃了，决定在客户端执行。

Maybe there is a way to tell webAPI not to put those extra slashes into the response ? I gave up and decided to do it on the client side.

问题是，我不得不更改dojo库中的iframe.js文件，非常糟糕。

Problem is, i had to change the iframe.js file in the dojo library which is very bad.

推荐答案

我自己解决了这个问题，这里是服务器端解决方案：

I solved the problem by myself, here is the server side solution:

json = System.Web.HttpUtility.HtmlEncode(json)
Dim msg = "<textarea>" + json + "</textarea>"

dojo文件上传器现在可以理解响应，并可以正确解析。

The dojo file uploader now understands the response and can parse it correctly.
