TCnHttpClient Class
Provides a base class for sending HTTP requests and receiving HTTP responses from a resource identified by a URI.
type TCnHttpClient = class(TClrBaseComponent) end;
The TCnHttpClient type exposes the following members.
| Name | Description | |
|---|---|---|
 | Create(TComponent) | Creates and initializes a TCnHttpClient instance. (Overrides TClrBaseComponent.Create(TComponent).) |
| Destroy | Frees the resources allocated with a TCnHttpClient instance. (Overrides TClrBaseComponent.Destroy.) |
| Name | Description | |
|---|---|---|
 | BaseAddress | Gets or sets the base address of Uniform Resource Identifier (URI) of the Internet resource used when sending requests. |
 | DefaultClrObject | Get the common language runtime object interface for this component. (Inherited from TClrBaseComponent.) |
| DefaultRequestHeaders | Gets the headers which should be sent with each request. |
| MaxResponseContentBufferSize | Gets or sets the maximum number of bytes to buffer when reading the response content. |
| Timeout | Gets or sets the timespan to wait before the request times out. |
| Name | Description | |
|---|---|---|
| CancelPendingRequests | Cancel all pending requests on this instance. |
| DeleteAsync(String) | Overloaded. Send a DELETE request to the specified Uri as an asynchronous operation. |
| DeleteAsync(String,_CancellationToken) | Overloaded. Send a DELETE request to the specified Uri with a cancellation token as an asynchronous operation. |
| DeleteAsync(_Uri) | Overloaded. Send a DELETE request to the specified Uri as an asynchronous operation. |
| DeleteAsync(_Uri,_CancellationToken) | Overloaded. Send a DELETE request to the specified Uri with a cancellation token as an asynchronous operation. |
| Dispose | Releases the unmanaged resources used by the HttpClient and optionally disposes of the managed resources. |
 | DoGetDefaultClrObject | Represents method |
| DoGetDotNetBaseComponent | Represents method |
| GetAsync(String) | Overloaded. Send a GET request to the specified Uri as an asynchronous operation. |
| GetAsync(String,THttpCompletionOption) | Overloaded. Send a GET request to the specified Uri with an HTTP completion option as an asynchronous operation. |
| GetAsync(String,THttpCompletionOption,_CancellationToken) | Overloaded. Send a GET request to the specified Uri with an HTTP completion option and a cancellation token as an asynchronous operation. |
| GetAsync(String,_CancellationToken) | Overloaded. Send a GET request to the specified Uri with a cancellation token as an asynchronous operation. |
| GetAsync(_Uri) | Overloaded. Send a GET request to the specified Uri as an asynchronous operation. |
| GetAsync(_Uri,THttpCompletionOption) | Overloaded. Send a GET request to the specified Uri with an HTTP completion option as an asynchronous operation. |
| GetAsync(_Uri,THttpCompletionOption,_CancellationToken) | Overloaded. Send a GET request to the specified Uri with an HTTP completion option and a cancellation token as an asynchronous operation. |
| GetAsync(_Uri,_CancellationToken) | Overloaded. Send a GET request to the specified Uri with a cancellation token as an asynchronous operation. |
| GetByteArrayAsync(String) | Overloaded. Send a GET request to the specified Uri with a cancellation token as an asynchronous operation. |
| GetByteArrayAsync(_Uri) | Overloaded. Send a GET request to the specified Uri and return the response body as a byte array in an asynchronous operation. |
| GetClrObject | Represents method |
| GetStreamAsync(String) | Overloaded. Send a GET request to the specified Uri and return the response body as a stream in an asynchronous operation. |
| GetStreamAsync(_Uri) | Overloaded. Send a GET request to the specified Uri and return the response body as a stream in an asynchronous operation. |
| GetStringAsync(String) | Overloaded. Send a GET request to the specified Uri and return the response body as a string in an asynchronous operation. |
| GetStringAsync(_Uri) | Overloaded. Send a GET request to the specified Uri and return the response body as a string in an asynchronous operation. |
| PostAsync(String,_HttpContent) | Overloaded. Send a POST request to the specified Uri as an asynchronous operation. |
| PostAsync(String,_HttpContent,_CancellationToken) | Overloaded. Send a POST request with a cancellation token as an asynchronous operation. |
| PostAsync(_Uri,_HttpContent) | Overloaded. Send a POST request to the specified Uri as an asynchronous operation. |
| PostAsync(_Uri,_HttpContent,_CancellationToken) | Overloaded. Send a POST request with a cancellation token as an asynchronous operation. |
| PutAsync(String,_HttpContent) | Overloaded. Send a PUT request to the specified Uri as an asynchronous operation. |
| PutAsync(String,_HttpContent,_CancellationToken) | Overloaded. Send a PUT request with a cancellation token as an asynchronous operation. |
| PutAsync(_Uri,_HttpContent) | Overloaded. Send a PUT request to the specified Uri as an asynchronous operation. |
| PutAsync(_Uri,_HttpContent,_CancellationToken) | Overloaded. Send a PUT request with a cancellation token as an asynchronous operation. |
| RegisterEventCallBack(ClrWString,Pointer) | Add an event to the instance using the specified event name and function pointer which is the event handler. The RegisterEventCallBack method does not directly add the event handler to the event. A hooking mechanism is used such that if the event is fired, the hook event is also fired which in turn calls the function pointer. (Inherited from TClrBaseComponent.) |
| RegisterEventSource | Register the Delphi object which will raise the .Net event handler. (Inherited from TClrBaseComponent.) |
| SendAsync(_HttpRequestMessage) | Overloaded. Send an HTTP request as an asynchronous operation. |
| SendAsync(_HttpRequestMessage,THttpCompletionOption) | Overloaded. Send an HTTP request as an asynchronous operation. |
| SendAsync(_HttpRequestMessage,THttpCompletionOption,_CancellationToken) | Overloaded. Send an HTTP request as an asynchronous operation. |
| SendAsync(_HttpRequestMessage,_CancellationToken) | Overloaded. Send an HTTP request as an asynchronous operation. |
| UnRegisterEventCallBack(ClrWString,Pointer) | Remove an event from the instance using the specified event name and function pointer which is the event handler. (Inherited from TClrBaseComponent.) |
| UnRegisterEventSource | Unregister the Delphi object which raised the .Net event handler. (Inherited from TClrBaseComponent.) |
