JWeb: Java Http Connection

JWeb is a Java library for connecting to Http servers and fetch html or json data.

Getting start

Maven

Add JitPack to maven repositories:

<repositories>
	<repository>
	    <id>jitpack.io</id>
	    <url>https://www.jitpack.io</url>
	</repository>
</repositories>

Add the dependency:

<dependency>
    <groupId>com.github.sadeghpro</groupId>
    <artifactId>jweb</artifactId>
    <version>0.9.0</version>
</dependency>

Gradle

Add this in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://www.jitpack.io' }
	}
}

and then in dependencies:

dependencies {
    implementation 'com.github.sadeghpro:jweb:0.9.0'
}

Example

Fetch the Wikipedia homepage:

JWeb web = new JWeb();
Response response = web.connect("https://en.wikipedia.org/wiki/Main_Page")
    .setMethod(Method.GET)// optional default is GET
    .addHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36")
    //.setBody("username=name&password=pass") // set body
    .setTimeout(1000)
    .exec();
System.out.println(response.getStatusCode() + ":" + response.getBody());

Set default header and default url:

JWeb web = new JWeb();
Map<String, String> headers = new HashMap<>();
headers.put("Content-Type", "application/json");
web.setDefaultHeaders(headers);
web.setDefaultUrl("https://en.wikipedia.org/wiki"); // only work when use JWeb.connect with string parameter
web.connect("/Main_Page").exec();

You can deserialize response body:

JWeb web = new JWeb();
Response response = web.connect("/products").exec();
List<Product> products = r.deserializeJsonArray(Product.class);
response = web.connect("/products/1").exec();
Product product = r.deserializeJsonObject(Product.class);
