#SyncHttpClient for Java by Callum Taylor
#Usage example
Note Because of the way SyncHttpClient works, only one instance can be created at a time. If one client makes 2 requests, the first request is canceled for the new request. You can either wait for the first to finish before making the second, or can create two seperate instances.
SyncHttpClient is a paramitized class which means the type you infer to it, is the type that gets returned when calling the method. When supplying a {@link Processor}, that processor must also paramitized with the same type as the SyncHttpClient instance.
##Example GET
SyncHttpClient<JsonElement> client = new SyncHttpClient<JsonElement>("http://example.com");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("key", "value"));
List<Header> headers = new ArrayList<Header>();
headers.add(new BasicHeader("1", "2"));
JsonElement response = client.get("api/v1/", params, headers, new JsonProcessor());##Example DELETE
SyncHttpClient<JsonElement> client = new SyncHttpClient<JsonElement>("http://example.com");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("key", "value"));
List<Header> headers = new ArrayList<Header>();
headers.add(new BasicHeader("1", "2"));
JsonElement response = client.delete("api/v1/", params, headers, new JsonProcessor());##Example POST - Single Entity
SyncHttpClient<JsonElement> client = new SyncHttpClient<JsonElement>("http://example.com");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("key", "value"));
List<Header> headers = new ArrayList<Header>();
headers.add(new BasicHeader("1", "2"));
JsonEntity data = new JsonEntity("{\"key\":\"value\"}");
GzippedEntity entity = new GzippedEntity(data);
JsonElement response = client.post("api/v1/", params, entity, headers, new JsonProcessor());##Example POST - URL Encoded post data
SyncHttpClient<JsonElement> client = new SyncHttpClient<JsonElement>("http://example.com");
RequestEntity entity = new RequestEntity();
entity.add("key", "value");
JsonElement response = client.post("api/v1/", params, entity, headers, new JsonProcessor());
});##Example POST - Multiple Entity + file
SyncHttpClient<JsonElement> client = new SyncHttpClient<JsonElement>("http://example.com");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("key", "value"));
List<Header> headers = new ArrayList<Header>();
headers.add(new BasicHeader("1", "2"));
MultiPartEntity entity = new MultiPartEntity();
FileBody data1 = new FileBody(new File("/IMG_6614.JPG"), "image/jpeg");
JsonEntity data2 = new JsonEntity("{\"key\":\"value\"}");
entity.addPart("image1.jpg", data1);
entity.addPart("content1", data2);
JsonElement response = client.post("api/v1/", params, entity, headers, new JsonProcessor());##Example PUT
SyncHttpClient<JsonElement> client = new SyncHttpClient<JsonElement>("http://example.com");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("key", "value"));
List<Header> headers = new ArrayList<Header>();
headers.add(new BasicHeader("1", "2"));
JsonEntity data = new JsonEntity("{\"key\":\"value\"}");
GzippedEntity entity = new GzippedEntity(data);
JsonElement response = client.put("api/v1/", params, entity, headers, new JsonProcessor());##Example custom processor
SyncHttpClient<String> client = new SyncHttpClient<String>("http://example.com");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("key", "value"));
String encodedResponse = client.get("api/v1/", params, new Processor()
{
private StringBuffer stringBuffer;
@Override public void onPublishedDownloadProgress(byte[] chunk, int chunkLength, long totalProcessed, long totalLength)
{
if (stringBuffer == null)
{
int total = (int)(totalLength > Integer.MAX_VALUE ? Integer.MAX_VALUE : totalLength);
stringBuffer = new StringBuffer(Math.max(8192, total));
}
if (chunk != null)
{
try
{
// Shift all the bytes right
byte tmp = chunk[chunk.length - 1];
for (int index = chunk.length - 2; index >= 0; index--)
{
chunk[index + 1] = chunk[index];
}
chunk[0] = tmp;
stringBuffer.append(new String(chunk, 0, chunkLength, "UTF-8").);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
@Override public String getContent()
{
return stringBuffer.toString();
}
});Because of the nature of REST, GET and DELETE requests behave in the same way, POST and PUT requests also behave in the same way.
