Why is my json file not found?
提问by B. Clay Shannon
I have a json file in a Content folder within my asp.net project:
我的 asp.net 项目的 Content 文件夹中有一个 json 文件：
<projectName>
\Content
NBCCJr.json
...and the code to access it:
...以及访问它的代码：
$.getJSON('~/Content/NBCCJr.json', function (data) {
$.each(data, function(i, dataPoint) {
// Bla
});
});
)
...but nothing happens when the code is called; the browser console says, "Failed to load resource: the server responded with a status of 404 (Not Found)"
...但是当代码被调用时什么也没有发生；浏览器控制台显示“加载资源失败：服务器响应状态为 404（未找到）”
Why is it not found? Isn't "tilde whack filename" the correct route to the file?
为什么找不到？“波浪号重击文件名”不是文件的正确路径吗？
UPDATE
更新
I also tried it with the "whacks" backwards:
我还用“重击”向后尝试了它：
$.getJSON('~\Content\NBCCJr.json', function (data) {
...and got the same result ("Failed to load resource: the server responded with a status of 404 (Not Found)")
...并得到相同的结果（“加载资源失败：服务器响应状态为 404（未找到）”）

Then I tried it sans a prepended whack thusly:
然后我尝试了它没有预先准备好的重击：
$.getJSON('Content/NBCCJr.json', function (data) {
...and I get this ambiguous message in the console:
...我在控制台中收到了这条模棱两可的消息：
*GET http://localhost:9702/Content/NBCCJr.json 404 (Not Found) jquery.js:8724
XHR finished loading: "http://localhost:9702/Content/NBCCJr.json".*
So it was not found and yet loaded anyway?
所以它没有被找到并且仍然被加载？

When I attempted to navigate to the file in the browser by changing:
当我尝试通过更改导航到浏览器中的文件时：
http://localhost:9702/Default.cshtml
...to:
...到：
http://localhost:9702/Content/NBCCJr.json
I got an informative WSOD message from Vint Cerf, Tim Berners-Lee, and/or Al Gore saying:
我收到了来自 Vint Cerf、Tim Berners-Lee 和/或 Al Gore 的信息丰富的 WSOD 消息：
HTTP Error 404.3 - Not Found The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.
HTTP 错误 404.3 - Not Found 由于扩展配置，无法提供您请求的页面。如果页面是脚本，则添加处理程序。如果应该下载文件，请添加 MIME 映射。

I had to add this to Web.Config:

</staticContent>
</system.webServer>

Have you tried removing the ~?
你有没有试过删除~？
As in:
如：
$.getJSON('/Content/dumboJr.json', function (data) {
$.each(data, function(i, dataPoint) {
// Bla
});
});
)
To allow the IIS to serve JSON files, try adding this to your web.config:
要允许 IIS 提供 JSON 文件，请尝试将其添加到您的 web.config：
<staticContent>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>

Solution is you need to add json file extension type in MIME Types
解决方法是需要在MIME Types中添加json文件扩展名
Method 1
方法一
Go to IIS, Select your application and Find MIME Types
转到 IIS，选择您的应用程序并查找 MIME 类型
Click on Add from Right panel
单击右侧面板中的添加
File Name Extension = .json
文件扩展名 = .json
MIME Type = application/json
MIME 类型 = 应用程序/json
After adding .jsonfile type in MIME Types, Restart IISand try to access json file
在MIME Types 中添加.json文件类型后，重启 IIS并尝试访问 json 文件
Method 2
方法二
Go to web.config of that application and add this lines in it
转到该应用程序的 web.config 并在其中添加此行
<system.webServer>
<staticContent>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
</system.webServer>

Try putting the *.json file in the webRoot, not in a sub folder. And then reference it like:
尝试将 *.json 文件放在 webRoot 中，而不是放在子文件夹中。然后像这样引用它：
$.getJSON('NBCCJr.json', function (data) {This of course requires the previous inclusion and instantiation of the jQuery system object from: jquery.min.jsor the JSON structure from: json2-1.0.min.js
这当然需要jQuery的系统对象的从以前的夹杂物和实例：jquery.min.js从或JSON结构：json2-1.0.min.js

I Changed .json to .txt and request is working fine. I am not sure about the consequence .txt can cause.
我将 .json 更改为 .txt 并且请求工作正常。我不确定 .txt 可能导致的后果。

If you use ASP.NET Core, just put the file in wwwrootbut if you use ASP.NETframework, this allows JSON extension from web.config as follows:
如果您使用ASP.NET Core，只需将文件放入wwwroot但如果您使用ASP.NET框架，这将允许来自 web.config 的 JSON 扩展，如下所示：
<staticContent>
<mimeMap fileExtension=".json" mimeType="application/json" />
</staticContent>
and
和
<location path="Content">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
