我是否需要 HTTP GET 请求的内容类型标头? [英] Do I need a content-type header for HTTP GET requests?
问题描述
据我所知，有两个地方可以设置内容类型:
As far as I understood there are two places where to set the content type:
- 客户端为他发送到服务器的正文设置内容类型(例如，用于发布)
- 服务器为响应设置内容类型.
这是否意味着我不必或不应该为我的所有获取请求(客户端)设置内容类型.如果我可以或应该是什么内容类型?
Does this mean I don't have to or should not set a content type for all my get requests (client side). And if I can or should what content type would that be?
我还在一些帖子中读到，客户端的内容类型指定了客户端想要接收的内容类型.所以也许我的第 1 点是不对的?
Also I read in a few posts that the content type of the client specifies what type of content the client would like to receive. So maybe my point 1 is not right?
推荐答案
生成包含有效负载正文的消息的发送者应该在该消息中生成一个 Content-Type 标头字段，除非发送者不知道封闭表示的预期媒体类型.如果 Content-Type 头域不存在，接收者可以假设媒体类型为application/octet-stream"；([RFC2046]，第 4.5.1 节)或检查数据以确定其类型.
A sender that generates a message containing a payload body SHOULD generate a Content-Type header field in that message unless the intended media type of the enclosed representation is unknown to the sender. If a Content-Type header field is not present, the recipient MAY either assume a media type of "application/octet-stream" ([RFC2046], Section 4.5.1) or examine the data to determine its type.
这意味着 Content-Type HTTP 头应该只为 PUT 和 POST 请求设置.
It means that the Content-Type HTTP header should be set only for PUT and POST requests.
