Folks
Now that HttpClient 5.2 runs I would like to deprecate a decade old way
of handling responses in favor of HttpClientResponseHandler functional
interface approach:
This common pattern should be discouraged going forward
```
try (final CloseableHttpResponse response = httpclient.execute(httppost)) {
System.out.println("----------------------------------------");
System.out.println(response.getCode() + " " +
response.getReasonPhrase());
System.out.println(EntityUtils.toString(response.getEntity()));
}
```
and be replaced by this one:
```
httpclient.execute(httppost, response -> {
System.out.println("----------------------------------------");
System.out.println(response.getCode() + " " +
response.getReasonPhrase());
System.out.println(EntityUtils.toString(response.getEntity()));
return null;
});
```
There are several advantages to the functional interface based approach:
1. it eliminates the entire class of resource leaks due sloppy exception
handling in the application code.
2. it would make it easier to implement a classic i/o compatibility
layer on top of the async APIs should we ever decide to build such a thing.
On the downside some users might not like the fact that they would need
to adjust their existing HTTP response handling logic, but that is the
case with all new things.
Please let me know what you think.
