Warning
Info
Was trying to use graphql_client (GitHub - graphql-rust/graphql-client: Typed, correct GraphQL requests and responses in Rust) to work with github API, however I was unable to get either of the documented methods of use to work.
One method is to use the provided post_graphql function:
use graphql_client::{reqwest::post_graphql_blocking as post_graphql, GraphQLQuery};
use reqwest::blocking::Client;
let client = Client::builder()
.user_agent("graphql-rust/0.10.0")
.default_headers(
std::iter::once((
reqwest::header::AUTHORIZATION,
reqwest::header::HeaderValue::from_str(&format!("Bearer {}", PERSONAL_ACCESS_TOKEN))
.unwrap(),
))
.collect(),
)
.build()?;
let variables = github::project_id::Variables {
number: 1,
organization: organization.into()
};
let response_body =
post_graphql::<github::ProjectId, _>(&client, github_api, variables)?;
This does not work because the graphql_client provides it's own version of reqwest somehow which conflicts with the one I have in my project. I could not find a way to use the version used by graphql_client. They also do not appear to be conflicting versions, ">=0.11, <=0.12" and 0.12.23, so I don't even know what caused this issue.
error[E0308]: mismatched types

148 | post_graphql::<github::ProjectId, _>(&client, "https://api.github.com/graphql", variables).unwrap();
| ------------------------------------ ^^^^^^^ expected `reqwest::blocking::client::Client`, found `reqwest::blocking::Client`
| |
| arguments to this function are incorrect
|
note: two different versions of crate `reqwest` are being used; two types coming from two different versions of the same crate are different types even if they look the same
The other method
let query = github::ProjectId::build_query(variables);
let response = client.post(github_api).body(&query).send()?;
also does not work because graphql_client does not implement the required trait for reqwest.
error[E0277]: the trait bound `reqwest::blocking::Body: From<&QueryBody<Variables>>` is not satisfied
--> src/main.rs:149:49

149 | let response = client.post(github_api).body(&query).send()?;
| ---- ^^^^^^ the trait `From<&QueryBody<Variables>>` is not implemented for `reqwest::blocking::Body`
| |
| required by a bound introduced by this call

= help: the following other types implement trait `From<T>`:
`reqwest::blocking::Body` implements `From<&[u8]>`
`reqwest::blocking::Body` implements `From<&str>`
`reqwest::blocking::Body` implements `From<File>`
`reqwest::blocking::Body` implements `From<Vec<u8>>`
`reqwest::blocking::Body` implements `From<bytes::bytes::Bytes>`
`reqwest::blocking::Body` implements `From<std::string::String>`
= note: required for `&QueryBody<Variables>` to implement `Into<reqwest::blocking::Body>`
I eventually got it to work by manually serializing the query, but it feels like both of the other two approaches should have worked. Did I miss something obvious or is this crate kind of broken?
let b = serde_json::to_value(
&query
)?.to_string();
let response = client.post(github_api).body(b).send()?;
let response_body: Response<github::project_id::ResponseData> = response.json()?;
