问题描述

我有一种情况需要发送数据,但我不需要

响应。在我看来,XMLHTTPRequest是发送

数据的最佳方式,但我不需要从服务器回复任何响应。


基本上,我正在将js错误写入服务器端的错误日志 -

并且无需通知用户错误已被记录。


问题是我不想坐在请求打开和放大等待

作为回复,当我不需要回复时。我想我可以

服务器响应只是OK或类似的东西,但是它的确是不相关的b $ b


我在考虑只是在readystate = 1中删除请求(在那个

点,服务器端脚本应该已经执行了,对吧?),但是

我想知道是否还有其他方法可以发送..


Thanx

I have a situation where I want to send data, but I have no need for a
response. It seems to me that XMLHTTPRequest is the best way to send the
data, but I don''t need any response back from the server.

Basically, I''m writing js errors to an error log on the server side -
and there is no need to inform the user that the error has been logged.

The problem is that I don''t want to sit with the request open & waiting
for a response, when I have no need for the response. I suppose I could
have the server respond with just "OK" or something like that, but it''s
really not relevant

I was thinking of just aborting the request on readystate=1 (at that
point, the server-side script should have executed already, right?), but
I was wondering if there were any other methods to JUST send..

Thanx

推荐答案




Not一个脚本问题。请参阅HTTP规范,204 /无内容响应



Not a script question. See HTTP specs, 204 / No Content response





否,XMPHTTPRequest不是发送数据的最佳方式。特别是

,因为你不需要回复。


myVar = new Image();

myVar.src = " pathToServerSideScript.ext" + errorMessage;


然后服务器端脚本执行,没有任何响应。

No, XMPHTTPRequest is not the best way to send the data. Especially
since you don''t need the response.

myVar = new Image();
myVar.src = "pathToServerSideScript.ext?" + errorMessage;

Then the server side script executes and nothing is done with the response.

This is so widely asked that its in the FAQ:

这个老技巧总能奏效,但这只是一个技巧,我认为XHR是正确的方式

这样做。除了查询字符串也有一个

大小限制这一事实,所以这个技巧也不是发送数据的最佳方式。


如果你不需要发送大量数据,或者如果你需要

与旧浏览器的兼容性,那么......使用查询字符串。


否则我全都是XHR \ o /,因为对我来说这显然是正确的方式,

如果回复对你没关系,甚至不会产生它!由于

你只需要检查标题(有一种方法可以在这个XHR对象上获取

标题,但我认为它不存在于IE,搜索一下

小嘿嘿)。
