Graphql post body“必须提供查询字符串”。

Question

POST /graphql HTTP/1.1
Host: local:8083
Content-Type: application/graphql
Cache-Control: no-cache
Postman-Token: d71a7ea9-5502-d5fe-2e36-0ae49c635a29

{
   testing {
      pass(id: 1) {
        idn
      }
    }
}

{
  "errors": [
    {
      "message": "Must provide query string."
    }
  ]
}

mutation {
  update(id: 2, x1: "zazaza", x2: "zazaza", x3: "zazaza" ...(more more fields)...) {
    idn
  }
}

我想它一定是在请求体。我如何发送‘更新’查询或我做错了？

Answer 1

Post请求需要管理头信息。

使用Http客户端：Content-Type Application/JSON

使用邮递员客户端：Content-Type Application/GraphQL

{"query":"mutation{update(id:1,x1:\"zazaz\",x2:\"zazaz\"......){id x1 x2}}"}
