Graphql 帖子正文“必须提供查询字符串". [英] Graphql post body "Must provide query string."

问题描述

我使用 Express-graphql 中间件.我在正文行中发送以下请求:

I use Express-graphql middleware. I send the following request in the body line:

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
      }
    }
}

并且有错误

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

在 graphql 中，我可以在 URL 中发送更新.

in graphql i can send update in URL.

网址字符串太短.我必须像

URL string is too short. i must send update model like

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

我认为它必须在请求正文中.我如何发送更新"查询或我做错了什么?

i think its must be in request body. How can i send 'update' query or that i'm doing wrong?

推荐答案

Post 请求需要管理 headers 信息.

Post request needs to manage headers info.

1. 使用 Http 客户端:Content-Type application/json

1. Using Http client: Content-Type application/json

使用 Postman 客户端:Content-Type 应用程序/graphql

Using Postman client: Content-Type application/graphql

但请求正文看起来像字符串

but request body looks like string

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