I am trying to get xml data from apache ranger using it's rest api. Here is my code
val httpclient = new DefaultHttpClient()
val auth=new AuthScope(host,AuthScope.ANY_PORT)
val credentials=new UsernamePasswordCredentials(username, password)
httpclient.getCredentialsProvider()
.setCredentials(auth, credentials)
val httpget = new HttpGet("http://localhost:6080/service/public/api/repository/1")
httpget.setHeader("Accept", "application/xml")
val response = httpclient.execute(httpget)
val entity = response.getEntity
if (entity != null) {
val in = new BufferedReader(new InputStreamReader(entity.getContent()))
var line = in.readLine()
var response = new StringBuffer()
while (line != null) {
response.append(line)
line = in.readLine()
}
in.close()
println(response.toString())
}
If i hit this url from browser it shows result fine. But in case of code it returns html.
Any help?
Try this code
val httpclient = new DefaultHttpClient()
val httpget = new HttpGet("url")
httpget.addHeader(BasicScheme.authenticate(
new UsernamePasswordCredentials("user", "pass"),
"UTF-8", false))
httpget.setHeader("Accept", "application/json")
val response = httpclient.execute(httpget)
EntityUtils.toString(response.getEntity())
setting authentication in the request.
Thanks

I tried to send request to another service containing enum #RequestParam but it always fails.
Here's the example of my request;
fun upsertExclusionOverride(
request: request
): ExcOve? {
val builder = UriComponentsBuilder.fromUriString("/v1/p-b/e/bulk")
val httpEntity = RestTemplateUtils.getHttpEntityCustomHeaders(request, headers)
try {
val body = restTemplate
.exchange(
builder.toUriString(),
HttpMethod.POST,
httpEntity,
Response::class.java
)
.body
?: throw Exception("Fail")
return body.toDomain()
} catch (e: RestClientException) {
log.error(e.message)
throw Exception("Fail")
}
}
This is the other microservice;
#PostMapping("/e/bulk")
#ApiOperation("Exclude")
fun exclusionsInBulk(
#RequestParam(name = "operation", required = true) operation: Operation,
#RequestPart("file") #ApiParam(
value = "File",
required = true,
format = "byte"
) file: MultipartFile
): ResponseEntity<Response> {
.....
}
How should I prevent 400 Bad Request?
I added enum converter but it didn't work.
I expect it to not to get 400 Bad Request.
I am trying to modernize some calls to Moodle REST APIs.
Everything is doing OK as long as I use querystring, but I can't pinpoint why using a PutAsync doesn't work in this case (tested with Postman, it works):
using (var httpClient = _httpClientFactory.CreateClient())
{
var url = "http://127.0.0.1/moodle/webservice/rest/server.php";
var urlFunction = UrlFunction.core_user_create_users.ToString();
var urlFormat = UrlFormat.json.ToString();
var requestModel = new GetCoursesRequestModel()
{
wstoken = [token],
wsfunction = urlFunction,
moodlewsrestformat = urlFormat
};
var jsonRequest = JsonConvert.SerializeObject(requestModel);
var stringContentRequest = new StringContent(jsonRequest, Encoding.UTF8, "application/json");
var response = await httpClient.PutAsync(url, stringContentRequest);
response.EnsureSuccessStatusCode();
var courseDtos = await response.Content.ReadFromJsonAsync<List<MoodleAPIDtosCourseDto>>();
if (courseDtos is null)
throw new InputFormatterException(
$"Pb with response format.");
}
ยดยดยดยด
The error is generated when I try to read my response at await response.Content.ReadFromJsonAsync()
I'm making a distributed sorting system, where each machine (client) has a specific range of values (partition) to store. I don't have any problem sending and receiving data, but the synchronization is my problem. Before retrieving the wanted partition from the server, it must first arrive to the server from one of the other clients.
I've tried with delay and various other RPC calls to try to try to synchronize the clients and server, but the clients run out of synchronization, and the program breaks. I think I have to incorporate future or promise, but I'm not sure how.
Every client has a unique ID (from 0 and up), and will store partitions according to that number. One line of data looks like this: AsfAGHM5om 00000000000000000000000000000000 0000222200002222000022220000222200002222000000001111
EDIT: updated code for example
Client
val numberOfClients = 3
var sentPartitionsCounter = 0
while(sentPartitionsCounter < numberOfClients) {
if(sentPartitionsCounter != id){
sendUnwantedPartition("src/main/scala/testFile."+sentPartitionsCounter.toString) //"partition."+client.sentPartitionsCounter
sentPartitionsCounter += 1
}
client.getWantedPartition()
}
def sendUnwantedPartition(filename: String): Unit = {
val dataList = Source.fromFile(filename).getLines.toList
val dataSeq = for {
dataLine <- dataList
dataValues = dataLine.split(" ", 2)
} yield (Data(key = dataValues(0), value = dataValues(1)))
val partitionID = filename takeRight 1
val request = Dataset(data = dataSeq, partitionID = partitionID.toInt)
val response = blockingStub.getUnwantedPartitions(request)
print("sent partitions")
}
def getWantedPartition(): Unit = {
val request = ID(id = id)
val response = blockingStub.sendWantedPartitions(request)
val wantedPartitions = new File("clientFiles/wantedPartitions"+id.toString+".txt")
val printWriter: PrintWriter = new PrintWriter(new FileWriter(wantedPartitions, true));
if(!wantedPartitions.exists()){
wantedPartitions.createNewFile()

How to generate swagger document for akka http web socket route ?
I have able to write akka Http get,put,post,delete. for example
#Path("/postPing")
#ApiOperation(value = "Find a ping", notes = "Returns a pong",
httpMethod = "POST",response = classOf[String])
#ApiImplicitParams(Array(
new ApiImplicitParam(name = "data", value = "\"data\" to sum", required = true,
dataType = "string", paramType = "query"),
new ApiImplicitParam(name = "file", required = true,
dataType = "file", paramType = "query")
))
#ApiResponses(Array(
new ApiResponse(code = 404, message = "websocket not found"),
new ApiResponse(code = 200, message = "websocket found"),
new ApiResponse(code = 400, message = "Invalid websocket supplied")))
def postRoute = path("postPing") {
complete("post pong")
}
But I need for Akka web socket
def webSocketRoute: Route = path("websocket") {
handleWebSocketMessages(broadcast)
}
def broadcast: Flow[Message, Message, Any] = {
Flow[Message].mapConcat {
case tm: TextMessage =>
TextMessage(tm.textStream) :: Nil
}
}
For example
To connect with websocket server
/connect ws://echo.websocket.org/websocket
To send data to websocket server
/send Hello\ world
Thanks in Advance
