浏览器支持多部分响应 [英] Browser support of multipart responses
问题描述
我想使用multipart / mixed创建HTTP响应，但我不确定哪些浏览器支持它;从客户的角度来看，如果它听起来那么方便。
说实话，我不需要专门的内容类型。我只想在同一个响应中传输多个文件;也许还有更多使用的内容类型。
I would like to create a HTTP response, using multipart/mixed, but I'm not sure which browsers support it; and if it's as convenient as it sounds, from the client's point of view. To be honest, I do not need specifically that content type. I just want to transmit more than one file in the same response; maybe there's another content-type more used.
推荐答案
我已经测试了它，使用自制服务器和简单的响应。不确定响应是否格式正确，因为没有浏览器100％理解它。但结果如下：
I've tested it, with a home-made server and a simple response. Not sure if the response is well-formed because no browser understands it 100% OK. But here are the results:
- Firefox 3.5 ：仅渲染最后一部分，其他部分将被忽略。
- IE 8 ：将所有内容显示为文本/纯文本，包括边界。
- Chrome 3 ：将所有内容保存在一个文件中，不会呈现任何内容。
- Safari 4 ：将所有内容保存在一个文件中，没有渲染。
- Opera 10.10 ：奇怪的东西。开始将第一部分渲染为纯文本/文本，然后清除所有内容。加载进度条挂起31％。
- Firefox 3.5: Renders only the last part, others are ignored.
- IE 8: Shows all the content as if it were text/plain, including the boundaries.
- Chrome 3: Saves all the content in a single file, nothing is rendered.
- Safari 4: Saves all the content in a single file, nothing is rendered.
- Opera 10.10: Something weird. Starts rendering the first part as plain/text, and then clears everything. The loading progress bar hangs on 31%.
这是完整的回复，如果有人发现任何错误，请告诉我，我会再试一次：
