graphql - 在GraphQL中，我可以使用Content-Type : application/graphql?发送变量吗

Question

我试过在graphql中使用变量，
但是用'application/graphql'发送变量似乎是不可能的。

我是否应该继续转到Content-Type:'application/json'？

Answer 1

http://graphql.org/learn/serving-over-http/#post-request

A standard GraphQL POST request should use the application/json content type, and include a JSON-encoded body of the following form:

{
  "query": "...",
  "operationName": "...",
  "variables": { "myVariable": "someValue", ... }
}

operationName and variables are optional fields. operationName is only required if multiple operations are present in the query.

In addition to the above, we recommend supporting two additional cases:

... If the "application/graphql" Content-Type header is present, treat the HTTP POST body contents as the GraphQL query string.

以我的理解， Content-Type: "application/graphql"是无变量查询的简写。

所以我的答案是“是的，如果我要使用变量字段，则必须使用 Content-Type: "application/json" header
