HTML encoding ° degree symbol extra space
提问by Zac
<div id="a">°F</div>$.get("http://blah.com/go",{'TU':$('#a').text()});- IIS server logs show the following params:
99.5% of the time: TU=%C2%B0F
0.5% of the time: TU=%C2%B0+F - server subsequently crashes because it doesn't know what '° F' is. Admittedly one of the flaws is that we are scraping text out of the DOM & sending it to our server. This is where I suspect the problem is, but I would like to understand more.
<div id="a">°F</div>$.get("http://blah.com/go",{'TU':$('#a').text()});- IIS 服务器日志显示以下参数：
99.5% 的时间：TU=%C2%B0F
0.5% 的时间：TU=%C2%B0+F - 服务器随后崩溃，因为它不知道“° F”是什么。不可否认，其中一个缺陷是我们正在从 DOM 中抓取文本并将其发送到我们的服务器。这是我怀疑问题所在，但我想了解更多。
Other info: the 0.5% of the time has been both IE8 & Chrome. All IP's geolocated to Columbia, which makes it seem like a local issue, but we've been unable to replicate it.
其他信息：0.5% 的时间是 IE8 和 Chrome。所有 IP 都在地理定位到哥伦比亚，这使它看起来像是一个本地问题，但我们一直无法复制它。
Ideas??
想法？？

So the problem is that sometimes there is a space between the °and the F, that space gets translated into a +, and the server doesn't accept it? If so, why not strip out the space before sending it?
所以问题是有时在°和之间有一个空格F，该空格被转换为 a +，而服务器不接受它？如果是这样，为什么不在发送之前去掉空格？
$.get("http://blah.com/go",{'TU':$('#a').text().replace(' ', '')});
// Or a more granular fix
$.get("http://blah.com/go",{'TU':$('#a').text().replace(/°\sF/, '°F')});

How is the text being put into the div? You should output that before checking the server value. I don't think it's likely that you're getting a different encoding of the same text. It's probably something to do with how you're putting it into the page.
文本是如何放入 div 中的？您应该在检查服务器值之前输出它。我认为您不太可能获得相同文本的不同编码。这可能与您如何将其放入页面有关。
Also try setting the page encoding on the server before you get the query string, it could be that different browsers are using a different encoding. UTF-8 is the encoding suggested by w3.org. In Java, you have to make sure you set the encoding before any calls to read anything from the client.
还可以尝试在获取查询字符串之前在服务器上设置页面编码，可能是不同的浏览器使用不同的编码。UTF-8 是 w3.org 建议的编码。在 Java 中，您必须确保在任何从客户端读取任何内容的调用之前设置编码。
