Converting from HttpClient 3 to 4

Question

I\'ve managed to make changes to everything but the following:

HttpClient client;
HttpPost method;   
client = new DefaultHttpClient();
method = new HttpPost(url         


        

Answer 1

Use EntityUtils and check the returned entity to be not null before consuming the entity:

InputStream rstream;
try {
    HttpResponse response = client.execute(HttpHost, method);

    rstream = Optional.ofNullable(httpResponse.getEntity())
    .map(e -> response.getContent()).orElse(null);

} catch (IOException e) {
    return BadSpot(e.getMessage()); 
}

NOTE: the InputStream here can be null and most of all you have to ensure that it's consumed before you actually close the response/release the connection.

Answer 2

The util class has some helpful methods:

EntityUtils.toString(response.getEntity());

There is also some useful stuff in the examples at apache's website

Answer 3

InputStream rstream;
try {
    HttpResponse response = client.execute(HttpHost, method);
    rstream = response.getEntity().getContent();
} catch (IOException e) {
    return BadSpot(e.getMessage()); 
}

above should do what you are asking.

Answer 4

HttpResponse.getEntity(), followed by HttpEntity.getContent()
