How to use Graphql query with Talend?

[hiba1]

Hi Talend Team,

I want to use graphQL query with talend.

I use tRest component. at first, it works.

This is the body:

"{ \"query\": \"query { hotelX { hotels(criteria: { access: \\\"21962\\\", maxSize: 500, hotelCodes: [\\\"\\\"] }, token: \\\"\\\", relay: {}) { token edges { node { code hotelData { hotelCode hotelCodeSupplier hotelName categoryCode rank location { address city zipCode country coordinates { latitude longitude } } medias { code order type updatedAt url texts { text language } } } } } } } }\" }"

The problem is that the token should be dynamic.

it tries this :

"{ \"query\": \"query { hotelX { hotels(criteria: { access: \\\"21962\\\", maxSize: 500, hotelCodes: [\\\"\\\"] }, token: \\\"\\\", relay: {}) { token edges { node { code hotelData { hotelCode hotelCodeSupplier hotelName categoryCode rank location { address city zipCode country coordinates { latitude longitude } } medias { code order type updatedAt url texts { text language } } } } } } } }\" }"

But it returns | Body    | {"data":null,"errors":[{"message":"Expected ',' or '}' after property value in JSON at position 138"}]} |

| ERROR_CODE | 400

Any help please on this .

Thanks in advance

Hi

I don't see the difference between the first body string and second body string? You want to pass a dynamic token value to the body string?

Hi @Shicong Hong​ ,

You want to pass a dynamic token value to the body string? ==> Yes

I try this one but I got an error:

"{ \"query\": \"query { hotelX { hotels(criteria: { access: \\\"21962\\\", maxSize: 500, hotelCodes: [\\\"\\\"] }, token: \\\"\" + (String)globalMap.get(\"token\") + \"\\\", relay: {}) { token edges { node { code hotelData { hotelCode hotelCodeSupplier hotelName categoryCode rank location { address city zipCode country coordinates { latitude longitude } } medias { code order type updatedAt url texts { text language } } } } } } }\" }"

Hi @hiba chaieb​ 

It seems this json is malformed. Here's some things I've noticed:

1. Its first element is encapsulated between quotes correctly (i.e.: \"query\"), while many other element names aren't.
2. There are too many escaped backslashes in some places like access: \\\"21962\\\". I suggest you use this instead: \"access\": \"21962\" ...
3. The String is not closing correctly to concatenate the token stored in globalMap. Try this instead: token: \"" + (String)globalMap.get("token") + "\", ...
