在GraphQL中，我可以发送内容类型为application/graphql的变量吗? [英] in GraphQL, Can I send variables with Content-Type: application/graphql?

问题描述

我尝试将变量与graphql一起使用，但似乎无法通过'application/graphql'发送变量.

I've tried to use variables with graphql, but it seems impossible to send variables with 'application/graphql'.

我是否必须继续使用Content-Type:'application/json'?

Should i have to move on to Content-Type: 'application/json'?

推荐答案

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

标准GraphQL POST请求应使用application/json内容类型，并包括以下形式的JSON编码主体:

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和变量是可选字段.仅当查询中存在多个操作时，才需要operationName.

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

除上述内容外，我们建议支持其他两种情况:

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

...如果存在"application/graphql" Content-Type标头，则将HTTP POST正文内容视为GraphQL查询字符串.

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

据我了解， Content-Type:"application/graphql" 是不带变量的查询的简写.

In my understanding, Content-Type: "application/graphql" is Shorthand for Querying without variables.

所以我的回答是是的，如果我想使用变量字段，则必须使用 Content-Type:"application/json" 标头

So my answer is "Yes, If I want to use variables field, I have to use Content-Type: "application/json" header
