Struct HttpRequestCanister 

pub struct HttpRequestCanister<'agent>(/* private fields */);

A canister that can serve a HTTP request.

Implementations

impl<'agent> HttpRequestCanister<'agent>

pub fn create(agent: &'agent Agent, canister_id: Principal) -> Self

Create an instance of a HttpRequestCanister interface pointing to the specified Canister ID.

pub fn from_canister(canister: Canister<'agent>) -> Self

Create a HttpRequestCanister interface from an existing canister object.

impl<'agent> HttpRequestCanister<'agent>

pub fn http_request<'canister: 'agent>( &'canister self, method: impl AsRef<str>, url: impl AsRef<str>, headers: impl IntoIterator<Item = HeaderField<'agent>, IntoIter = impl 'agent + Send + Sync + Clone + ExactSizeIterator<Item = HeaderField<'agent>>>, body: impl AsRef<[u8]>, certificate_version: Option<&u16>, ) -> impl 'agent + SyncCall<Value = (HttpResponse,)>

Performs a HTTP request, receiving a HTTP response.

pub fn http_request_custom<'canister: 'agent, H, T, C>( &'canister self, method: &str, url: &str, headers: H, body: &[u8], certificate_version: Option<&u16>, ) -> impl 'agent + SyncCall<Value = (HttpResponse<T, C>,)>

where H: 'agent + Send + Sync + Clone + ExactSizeIterator<Item = HeaderField<'agent>>, T: 'agent + Send + Sync + CandidType + for<'de> Deserialize<'de>, C: 'agent + Send + Sync + CandidType + for<'de> Deserialize<'de>,

Performs a HTTP request, receiving a HTTP response. T and C are the token and callback types for the streaming_strategy.

pub fn http_request_update<'canister: 'agent>( &'canister self, method: impl AsRef<str>, url: impl AsRef<str>, headers: impl 'agent + Send + Sync + Clone + ExactSizeIterator<Item = HeaderField<'agent>>, body: impl AsRef<[u8]>, ) -> impl 'agent + AsyncCall<Value = (HttpResponse,)>

Performs a HTTP request over an update call. Unlike query calls, update calls must pass consensus and therefore cannot be tampered with by a malicious node.

pub fn http_request_update_custom<'canister: 'agent, H, T, C>( &'canister self, method: &str, url: &str, headers: H, body: &[u8], ) -> impl 'agent + AsyncCall<Value = (HttpResponse<T, C>,)>

where H: 'agent + Send + Sync + Clone + ExactSizeIterator<Item = HeaderField<'agent>>, T: 'agent + Send + Sync + CandidType + for<'de> Deserialize<'de>, C: 'agent + Send + Sync + CandidType + for<'de> Deserialize<'de>,

Performs a HTTP request over an update call. Unlike query calls, update calls must pass consensus and therefore cannot be tampered with by a malicious node. T and C are the token and callback types for the streaming_strategy.

pub fn http_request_stream_callback<'canister: 'agent>( &'canister self, method: impl AsRef<str>, token: Token, ) -> impl 'agent + SyncCall<Value = (StreamingCallbackHttpResponse,)>

Retrieves the next chunk of a stream from a streaming callback, using the method from CallbackStrategy.

pub fn http_request_stream_callback_custom<'canister: 'agent, T>( &'canister self, method: impl AsRef<str>, token: T, ) -> impl 'agent + SyncCall<Value = (StreamingCallbackHttpResponse<T>,)>

where T: 'agent + Send + Sync + CandidType + for<'de> Deserialize<'de>,

Retrieves the next chunk of a stream from a streaming callback, using the method from CallbackStrategy. T is the token type.

Methods from Deref<Target = Canister<'agent>>

pub fn canister_id_(&self) -> &Principal

Get the canister ID of this canister. Prefer using canister_id instead.

pub fn canister_id(&self) -> &Principal

Get the canister ID of this canister.

pub fn update_<'canister>( &'canister self, method_name: &str, ) -> AsyncCallBuilder<'agent, 'canister>

Create an AsyncCallBuilder to do an update call. Prefer using update instead.

pub fn update<'canister>( &'canister self, method_name: &str, ) -> AsyncCallBuilder<'agent, 'canister>

Create an AsyncCallBuilder to do an update call.

pub fn query_<'canister>( &'canister self, method_name: &str, ) -> SyncCallBuilder<'agent, 'canister>

Create a SyncCallBuilder to do a query call. Prefer using query instead.

pub fn query<'canister>( &'canister self, method_name: &str, ) -> SyncCallBuilder<'agent, 'canister>

Create a SyncCallBuilder to do a query call.

pub async fn wait<'canister>( &'canister self, request_id: &RequestId, ) -> Result<Vec<u8>, AgentError>

Call request_status on the RequestId in a loop and return the response as a byte vector.

pub fn clone_with_(&self, id: Principal) -> Self

Creates a copy of this canister, changing the canister ID to the provided principal. Prefer using clone_with instead.

pub fn clone_with(&self, id: Principal) -> Self

Creates a copy of this canister, changing the canister ID to the provided principal.
