Using Wicked HTTP Client Library in Wicked for Secure Connections

Using the Wicked HTTP Client Library in Wicked

The Wicked HTTP client library provides an easy-to-use interface for making HTTP requests to web servers.

To use the library, you need to include the necessary header files and initialize the library before making any HTTP requests.

Initializing the Library

The first step in using the Wicked HTTP client library is to initialize it by calling the `http_client_init` function.

This function takes two arguments: a pointer to an `http_client_config_t` structure and a callback function that will be called when an HTTP request is completed.

Making HTTP Requests

Once the library is initialized, you can make HTTP requests using the `http_client_request` function.

This function takes several arguments, including the URL of the web server, the HTTP method to use (e.g. GET, POST), and any additional headers or data that need to be sent with the request.

Handling Responses

When an HTTP request is completed, the callback function specified in the `http_client_init` function will be called.

This callback function will receive a pointer to an `http_response_t` structure, which contains information about the response from the web server.

Using Secure Connections

To use secure connections with the Wicked HTTP client library, you need to specify the `HTTP_UseTLS` flag when initializing the library.

This will cause the library to establish a TLS connection with the web server instead of a plain HTTP connection.

Verifying Server Identity

When using secure connections, it's also important to verify the identity of the web server.

This can be done by checking the server's certificate and ensuring that it matches the expected identity.

Example Code

The following code snippet shows an example of how to use the Wicked HTTP client library to make a GET request to a web server:

http_client_init(NULL, callback_function);
http_client_request("https://www.example.com", "GET", NULL, NULL, NULL);

Security Considerations

When using the Wicked HTTP client library, it's essential to consider security.

This includes verifying server identity, checking for man-in-the-middle attacks, and ensuring that sensitive data is encrypted.

Conclusion

The Wicked HTTP client library provides a powerful and easy-to-use interface for making HTTP requests to web servers.

By following the guidelines outlined in this article, you can use the library to build secure and reliable networked applications.

• Web browsers (e.g., Chrome, Firefox)
• Command-line tools (e.g., curl, wget)
• Mobile apps
• Desktop applications
• Server-side applications

• Sending HTTP requests (GET, POST, PUT, DELETE, etc.)
• Handling HTTP responses (including headers and body)
• Caching and caching control
• Connection management (e.g., keep-alive, connection pooling)
• Error handling and reporting

Introduction

What is Wicked HTTP Client Library?

Key Features

• Support for HTTPS and TLS protocols
• Automatic connection pooling and reuse
• Configurable timeouts and retry policies
• Support for HTTP/2 multiplexing and server push
• Easy-to-use API with fluent interface

Secure Connections with Wicked HTTP Client Library

To establish a secure connection with Wicked HTTP Client Library, developers can use the following code snippet:

WickedHttpClient client = new WickedHttpClient.Builder()
  .sslContext(SSLContexts.custom().build())
  .build();

Configuring Security Settings

For example, to configure the library to use only TLSv1.2 and AES encryption, developers can use the following code snippet:

WickedHttpClient client = new WickedHttpClient.Builder()
  .sslContext(SSLContexts.custom()
    .setProtocol("TLSv1.2")
    .setCipherSuites("TLS_AES_256_GCM_SHA384", "TLS_CHACHA20_POLY1305_SHA256")
    .build())
  .build();

Conclusion

By following the guidelines outlined in this article, developers can use Wicked HTTP Client Library to establish secure connections with servers and protect their users' data from unauthorized access.

import io.wicked.http.client.WickedHttpClient;
WickedHttpClient client = new WickedHttpClient();

import javax.net.ssl.SSLContext;
SSLContext sslContext = SSLContext.getDefault();
client.setSslContext(sslContext);

import io.wicked.http.client.HttpRequest;
HttpRequest request = HttpRequest.get("https://example.com");
request.setClient(client);
HttpResponse response = client.execute(request);

client.setConnectionTimeout(5000); // 5 seconds
client.setIdleConnectionTimeout(30000); // 30 seconds
client.setMaxConnectionsPerRoute(10);
client.setMaxTotalConnections(50);
