Form content type for a json HTTP POST?
提问by rmk
Just wanted a clarification of the form content types:
只是想澄清表单内容类型：
application/x-www-form-urlencoded: This is where you can send params encoded with the url.multipart/form-data: ??
application/x-www-form-urlencoded：这是您可以发送使用 url 编码的参数的地方。multipart/form-data: ??
I need to send a JSON in the post (so it would have the type: text/x-json, I guess).
So the question is, is multipart/form-datasuitable for this purpose / is application/x-www-form-urlencodedbetter?
我需要在帖子中发送一个 JSON（所以它的类型是：text/x-json，我猜）。所以问题是，multipart/form-data适合这个目的/application/x-www-form-urlencoded更好吗？
Also, would it be possible to send some params encoded in the url, and some data in the json?
另外，是否可以发送一些编码在 url 中的参数和一些 json 中的数据？

It looks like people answered the first part of your question (use application/json).
看起来人们回答了您问题的第一部分（使用 application/json）。
For the second part: It is perfectly legal to send query parameters in a HTTP POST Request.
对于第二部分：在 HTTP POST 请求中发送查询参数是完全合法的。
Example:
例子：
POST /members?id=1234 HTTP/1.1
Host: www.example.com
Content-Type: application/json
{"email":"[email protected]"}
Query parameters are commonly used in a POST request to refer to an existing resource. The above example would update the email address of an existing member with the id of 1234.
查询参数通常用于 POST 请求以引用现有资源。上面的示例将更新 ID 为 1234 的现有成员的电子邮件地址。

I have wondered the same thing. Basically it appears that the html spec has different content types for html and form data. Json only has a single content type.
我也想过同样的事情。基本上，html 规范似乎对 html 和表单数据具有不同的内容类型。Json 只有一种内容类型。
According to the spec, a POST of json data should have the content-type:
application/json
根据规范，json 数据的 POST 应该具有内容类型：
application/json
