js warning: Resource interpreted as Script but transferred with MIME type text/plain
提问by tom81
i′m firing an ajax/jsonp request to my cloudant app:
我正在向我的 Cloudant 应用程序发出 ajax/jsonp 请求：
var obj = $.ajax({
url: "http://xyz",
dataType: 'jsonp',
success: function(data) {
//SOME CODE
},
error: function() {
//SOME CODE
}
});
the response is ok and i can read out my data. but I′m getting the following js warning:
响应正常，我可以读出我的数据。但我收到以下 js 警告：
Resource interpreted as Script but transferred with MIME type text/plain.
i need to make this request an jsonp request (cross domain policy), AFAIK jsonp returns as a script and gets executed by the browser. do i have to set a request header? I tried it with the 'accepts' and 'converters' options, but didn't make it work yet. (I′m using GoogleChrome, but also happens in Safari/FF)
我需要将此请求设为 jsonp 请求（跨域策略），AFAIK jsonp 作为脚本返回并由浏览器执行。我必须设置请求标头吗？我尝试了“接受”和“转换器”选项，但还没有让它工作。（我使用的是 GoogleChrome，但也发生在 Safari/FF）
cheers, tom
干杯，汤姆
PS: I want to get rid of the warning as this ajax request gets triggered every 2 seconds. So the console looks pretty bad...
PS：我想摆脱警告，因为此 ajax 请求每 2 秒触发一次。所以控制台看起来很糟糕......

The server should send a Content-Typeheader set to text/javascriptwhen it sends the JSONP script.
服务器应该在发送 JSONP 脚本时发送一个Content-Type设置为的标头text/javascript。

CouchDB itself is sending the text/plain content-type. The only other type you can convince it to send is 'application/json' if you send 'Accept: application/json' as a header.
CouchDB 本身正在发送文本/纯内容类型。如果您将“接受：应用程序/json”作为标题发送，您可以说服它发送的唯一其他类型是“应用程序/json”。
It seems that CouchDB should send text/javascript if delivering a jsonp response, though. If you could file a ticket I'm sure it would get done.
不过，如果提供 jsonp 响应，CouchDB 似乎应该发送文本/javascript。如果你能提交一张票，我相信它会完成。

Are you sending any encoding information in the headers? I had a problem with CouchDB responses and discovered that adding charset=utf-8to my Acceptor Content-Typeheading resulted in CouchDB returning the text/plaincontent instead of the application/jsonI was expecting. Perhaps you can solve this by altering your header if the case is similar enough.
您是否在标头中发送任何编码信息？我遇到了 CouchDB 响应的问题，发现添加charset=utf-8到我的Accept或Content-Type标题会导致 CouchDB 返回text/plain内容而不是application/json我期望的内容。如果情况足够相似，也许您可以通过更改标题来解决此问题。

Problem is on target server, because it's setting Content-Type: Text/plain
问题出在目标服务器上，因为它正在设置 Content-Type: Text/plain
You can't enforce it without access to target server. It should be Content-Type: text/javascript
您无法在无法访问目标服务器的情况下强制执行它。它应该是Content-Type: text/javascript
