如何通过邮递员发送图形查询？

There's a better way to do it using the REST client Insomnia

Docs are here, how to send graphql queries: https://support.insomnia.rest/article/61-graphql

Below are the steps for postman

Step 1.

Run the GraphiQL in Chrome, open the Chrome Dev Console, click the Network tab, and make the query from graphiql, when you make the query, network tab will show the graphql request...

Step 2.

From the graphql request copy the request query, Select the Copy as cURL (cmd)

Step 3.

Open Postman, In the Top-Left click on the Import button, after you click Import you have to click the Paste Raw Text, and paste the copied cURL request as done in step2 after it's done click the Import

Step 4.

Postman is ready to send the Graphql request, Just Click on the Send Button, you will see the Response in the Response Box in body as below

Step 5.

To see how the query is being sent click on the Body tab next to Headers, you will get know how to provide the fields from postman in JSON format.

e.g: edges {\n node {\n id\n jobId\n }\n, If you want to view another field then you need to add it in with the suffix \n

like if need name then : edges {\n node {\n id\n jobId\n name\n }\n

\n here just means to represent a new line. Instead, you can make it simpler by providing a clear and illustrative JSON like below

===========================================================================

Note: The body type must be raw with application/json content-type. So, the query must be a valid JSON with quotes ".."

{
"query":"{viewer {user {edges {node {id jobId name }}}}}"
}

===========================================================================

you can directly start from step 5 if you know how to send the query in body and other things too that needs to be required while making a request from postman

With simplified JSON

UPDATE 2:

It's not practical use POSTMAN, because the are working yet in a easy way to add headers, that take longtime, and i think POSTMAN is not made for work naturally with graphql,

you can follow the progress about that here: https://github.com/postmanlabs/postman-app-support/issues/1669

I recommend to use another packages plugin like:

the best (like postman , but profile and sync price 5$ monthly):
https://insomnia.rest/
others:
https://github.com/andev-software/graphql-ide
https://github.com/imolorhe

for graphiql (no add headers possibility) you need to set three things (it's not easy to type):

1. Header:

   Content-Type: application/json

2. Body:

   Choose Ray < optiongroup

   Choose JSON (application/json) < selectbox

3. Compose javascript object with "query" and the "value" of your graph query. Like all objects in js it'sneeded the propery and the value , in this case "quote" is the property, the value must be with double quotes. Inside the value (graphl string) you dont compose js objects, so you dont need use doble quotes, it's just a string.

   {"query":"{ allQuotes { text } }" }

   the problem is you need type all in a single line, no like grapIql... there is a post requirement in postman github so is easy work with graphql:

Adding this for anyone searching on the topic ... you can utilize and test GraphQL calls far better and more easily with Insomnia:

It's been fantastic for GraphQL development.

There's a simple way to do it. Use a pre-request script to stringify the payload (source).

Step 1.

In the body of the request put a placeholder for the payload.

{
"query":\{\{query}}
}

Step 2.

Create the payload in the pre-request script and store it in an environment variable.

postman.setEnvironmentVariable("query", JSON.stringify(
`
{
search(query: "test", type: ISSUE, first: 10) {
issueCount
edges {
node {
... on Issue {
title
id
state
closed
repository {
name
}
}
}
}
}
}
`
));

That's it.

You don't need INSOMNIA in case the GraphQL server responds to Content-type: application/graphql or postman.setEnvironmentVariable,

Just do it:

In Headers tab: Content-Type: application/graphql

In Body tab, "raw" selected, put your query

I faced the same problem when I try to used graphQl query using POSTMAN, In POSTMAN send data from the raw tab with json type.

Query Command:

{"query":"{user(id:902){id,username,DOB}}"}

Mutations Command:

{ "query": "mutation {createMutations(reviewer:36, comments:\"hello\",data_id: 1659, approved: true ){id}}" }


#commnent: String Type
#data_id:Int Type
#approved:Boolean Type

Checkout https://github.com/hasura/graphqurl - curl for GraphQL:

• CLI for making GraphQL queries with autocomplete
• Run GraphiQL locally against any endpoint (with custom headers)
• Use as a library with nodejs or from the browser
• Supports subscriptions

You can also use header Content-type: application/json on postman

And define the body with:

{
"query": "{ your_query }"
}

This is easily constructed on the client side to form a request payload.

e.g.

Output:

If you're using Visual Studio, I have written a plugin to convert GraphQL to Restful body

IF we can pass header type, Then add the header Content-type: application/graphql

Postman just released inbuilt GraphQL support in version 7.2.

This version supports

• Sending GraphQL queries in request body as POST requests
• Support for GraphQL variables
• Creating APIs in Postman with GraphQL schema type
• Query autocompletion integrated with user defined GraphQL schemas

Please give it a try and give us your feedback on the tracking thread on our community forum

Postman has recently launched its out of box support for GraphQL: https://blog.getpostman.com/2019/06/18/postman-v7-2-supports-graphql/

Below is the screenshot of testing GraphQL locally:

Note: Running GraphQL locally using spring-boot https://www.baeldung.com/spring-graphql

UPDATE 8-2019 - I know this is old, but regarding POSTMAN, if you haven't figured it out already, they do have a graphql (beta) option for posting body. There is no need to add any additional headers.

By adding header we can run graphql query in the postman

Content-type: application/graphql
