Graphql post body "Must provide query string."

Question

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       }     } } 

and have error

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

in graphql i can send update in URL.

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   } } 

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

Answer 1

Post request needs to manage headers info.

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

2. Using Postman client: Content-Type application/graphql

but request body looks like string

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

Answer 2

If you are using graphql and want to test it using postman or any other Rest client do this.

In postman, select POST method and enter your URL and set Content-Type as application/graphql then pass your query in the body.

Example:

http://localhost:8080/graphql Mehtod: POST Content-Type: application/graphql Body:    query{     FindAllGames{     _id     title     company     price     year     url    }  } 

Thats it you will get the response.
