I want to get mesos log dir like this
mesos-master --zk=zk://localhost:2181/mesos --log_dir=/Users/wangyao/WorkAndLog/mesos/log
/Users/wangyao/WorkAndLog/meoso/log
How could i get this in my code?
I try it with do GetRequest in my code like this
GetRequestHandler requestHandler = new GetRequestHandler() {
#Override
public String doGetRequestCallBack(HttpResponse response) throws IOException {
return EntityUtils.toString(response.getEntity());
}
};
Map<String, String> httpParams = new HashMap<String, String>();
String obj = HttpClientUtils.doGetRequest("http", "localhost", 5050, "/master/state.json", httpParams,
requestHandler);
in this way I can get the log_dir in the obj.
but I knew that the application server and mesos server is not using the same machine ,so I can't do the request with 'localhost', Generally it's not a viable way.
is there any way to get the log_dir?

I am not sure if it is possible to write a Test case that can mock the "http://localhost:8888/setup" site, so the above code can hit it and I want to check if the "http://localhost:8888/setup" received the inputStream correctly.
InputStream inputStream = //got the inputStream;
SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
requestFactory.setBufferRequestBody(false);
restTemplate.setRequestFactory(requestFactory);
InputStreamResource inputStreamResource = new InputStreamResource(inputStream){
#Override
public String getFilename(){
return filename;
}
#Override
public long contentLength(){
return -1;
}
}
MultiValueMap<String, Object> body = new LinkedMultiValueMap<>():
body.add("file", inputStreamResource);
HttpHeader headers = new HttpHeader();
headers.setContentType(MediaType.MULTIPART_FORM_DATA)LinkedMultiValueMap
HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(body, headers);
String url = "http://localhost:8888/setup";
restTemplate.postForObject(url, requestEntity, String.class);
Try using Wiremock!
Many ways of using it, back then when I used it, I used to run a JAR (wiremock jar) and it spawns up a program on your localhost with your port specified. Henceforth, you can test by hitting that localhost on the port it's up!

i have laravel site and i want create android app for this site
and im beginner in java .
In summary...
for authentication api route i use one middleware .
this middleware have one token .
in the postman program all thing is good...
but when i want send one post request with header token in volley android
my function cant give username or some variable ...
please help me to resolve this problem
this is my function send volly , dont forget all thing is good in postman request
int selectedId = statusregister.getCheckedRadioButtonId();
radioselect=(RadioButton)findViewById(selectedId);
send=0;
String url="my http api site...";
requestQueue= Volley.newRequestQueue(RegisterActivity.this);
StringRequest stringRequest=new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("response",response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("HttpClient", "error: " + error.toString());
}
}){
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>(); params.put("username",username.getText().toString().trim());
params.put("email",mailuser.getText().toString().trim());
params.put("password",password.getText().toString().trim());
params.put("status",radioselect.getText().toString().trim());
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params2 = new HashMap<String, String>();
params2.put("Content-Type", "application/json; charset=UTF-8");
params2.put("APP_KEY", "7ACFdsd328BEA81sssdfgg556B91");
return params2;
}
};
requestQueue.add(stringRequest);
}
401 erorr ...
when i remove middleware its ok ...
this is screenshot begore set APP_KEY in header
enter image description here
and this screenshot after set APP_KEY in header
enter image description here
401 is an authorization issue
The default API token name in laravel is access_token not APP_KEY
params2.put("access_token", "7ACFdsd328BEA81sssdfgg556B91");
The API_KEY is an environment variable used for encryption in Laravel and you're sending it as a header in a post request
I am using Google's Volley library for my application project , that targets minimum api level 14.So, Volley library uses HttpURLConnection as the NetworkClient.
Therefore , there should not be any issue related to Removal of Apache HTTPClient. However, I have done the configuration required for 6.0 Sdk i.e compileSdkVersion 23, build-tool-version 23.0.1 and build:gradle:1.3.1' and even tried adding useLibrary 'org.apache.http.legacy'. Have updated the same for Volley library project in my application.
Recently ,I tried to run my app on Android 6.0 (MarshMallow), my project compiles and runs. But those requests that require authentication headers are failing on MarshMallow with:
BasicNetwork.performRequest: Unexpected response code 401 com.android.volley.AuthFailureError
However the same is running on all Api level below 23.
I have checked the headers many times.Strangely, those requests that do not require authentication are giving response with 200 OK.
Right now I am totally clueless what is breaking the requests, does anybody have any idea what has changed in new Version that HttpURLConnection request fails for only Api level 23? Is anybody else using Volley and facing similar issue?
Here is my CustomRequest Class
public class CustomRequest extends Request<Void> {
int id, cmd;
Map<String, String> params;
BaseModel model;
public CustomRequest(int method, int cmd, String url, Map<String, String> params, int id, BaseModel model) {
super(method, url, null);
this.id = id;
this.cmd = cmd;
this.params = params;
this.model = model;
if (method == Method.GET) {
setUrl(buildUrlForGetRequest(url));
}
Log.v("Volley", "Making request to: " + getUrl());
}
private String buildUrlForGetRequest(String url) {
if (params == null || params.size() == 0) return url;
StringBuilder newUrl = new StringBuilder(url);
Set<Entry<String, String>> paramPairs = params.entrySet();
Iterator<Entry<String, String>> iter = paramPairs.iterator();
newUrl.append("?");
while (iter.hasNext()) {
Entry<String, String> param = iter.next();
newUrl
.append(param.getKey())
.append("=")
.append(param.getValue());
if (iter.hasNext()) newUrl.append("&");
}
return newUrl.toString();
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<String, String>();
headers.put("X-Api-Version", Contract.API_VERSION);
headers.put("X-Client", "android");
String accessToken = APP.getInstance().getToken();
if (!accessToken.equals("")) {
headers.put("Authorization", "Bearer " + accessToken);
}
return headers;
}
#Override
protected Response<Void> parseNetworkResponse(NetworkResponse response) {
Exception ex;
try {
String jsonString = new String(
response.data, HttpHeaderParser.parseCharset(response.headers));
JsonNode json = new ObjectMapper().readTree(jsonString);
if (model != null) model.parse(id, json);
EventBus.getDefault().post(new EventResponse(cmd, true, null));
return Response.success(null, HttpHeaderParser.parseCacheHeaders(response)); //Doesn't return anything. BaseModel.parse() does all the storage work.
} catch (NoMoreDataException e) {
ex = e;
EventBus.getDefault().post(new NoMoreDataModel(cmd, e));
EventBus.getDefault().post(new EventResponse(cmd, false, null));
return Response.success(null, HttpHeaderParser.parseCacheHeaders(response));
} catch (Exception e) {
ex = e;
Log.e("CustomRequest", Log.getStackTraceString(e));
String message = APP.getInstance().getString(R.string.failedRequest);
if (!TextUtils.isEmpty(e.getMessage()))
message = e.getMessage();
EventBus.getDefault().post(new ErrorEventModel(cmd, message, e));

Only difference I found between Api 23 and others is the HostNameVerifier.
For Api level 23 : com.android.okhttp.internal.tls.OkHostnameVerifier
For Api level <23 : javax.net.ssl.DefaultHostnameVerifier.
After checking the Server side of my application, found the reason behind the issue.
For Android 6.0(MarshMallow) the headers were becoming empty and this was not the case with other versions.
So the fix that worked for me:
Created and Added a new custom header X-Proxy-No-Redirect => 1 and passed along with other headers.
Theory behind it:
There is a API server to which we send request, then the API server redirects the request to corresponding site based on the oAuth token
While redirecting
For the redirection to happen, there are two ways to do that
1 - We just send a response back to the caller stating to redirect to a certain page. Then the caller(Networking library) takes care of redirection
2 - API server will itself makes the redirect request and get the response and then pass to caller
Earlier we were using the Method 1.
On Android 6.0 - The networking lib(Volley) doesn't seem to set all the headers while making the redirection request.
Once this new header is set, Method 2 will come into effective.
P.S This fix was applicable for my application project , maybe not for others.Just providing what was wrong and what helped me.
The scenario is: "Have adapters that work for HTTP, been asked to add FTP support" - sounds reasonable.
Is there a way to do it in an equally reasonable timeframe?
Or a similar mechanism/customized Volley library to swap Volley for?
The FTP is password-protected, if this makes any difference.
Tried so far:
HttpClientStack: Scheme 'ftp' not registered
HurlStack" libcore.net.url.FtpURLConnection cannot be cast to java.net.HttpURLConnection
attempted tunneling through a custom URLonnection (multiple difficulties, like libcore package not being public)
custom ImageCache that takes FTP handling off Volley's hands (what's the point, really?)
Only thing I've come up with thus far: override performRequest to do something completely different for ftp links.
Mind, the code here is bad, it just barely serves my purpose:
public class HurlStackFtp extends HurlStack {
#Override
public HttpResponse performRequest(Request<?> request, Map<String, String> additionalHeaders)
throws IOException, AuthFailureError {
String urlString = request.getUrl();
if (urlString != null && urlString.startsWith("ftp://")) {
return performFTPRequest(request, additionalHeaders);
} else {
return super.performRequest(request, additionalHeaders);
}
}
public HttpResponse performFTPRequest(Request<?> request, Map<String, String> additionalHeaders)
throws IOException, AuthFailureError {
String url = request.getUrl();
HashMap<String, String> map = new HashMap<String, String>();
map.putAll(request.getHeaders());
map.putAll(additionalHeaders);
// UrlRewriter not supported
InputStream input = getStreamFromFTP(url);
StatusLine responseStatus = new BasicStatusLine(new ProtocolVersion("HTTP", 1, 1),
/*connection.getResponseCode()*/200, /*connection.getResponseMessage()*/"OK");
BasicHttpResponse response = new BasicHttpResponse(responseStatus);
response.setEntity(makeEntity(input));
return response;
}
public static InputStream getStreamFromFTP(String url) throws IOException {
URL parsedUrl = new URL(url);
URLConnection cn = parsedUrl.openConnection();
cn.connect();
return cn.getInputStream();
}
private static HttpEntity makeEntity(InputStream inputStream) throws IOException {
BasicHttpEntity entity = new BasicHttpEntity();
entity.setContent(inputStream);
entity.setContentLength(inputStream.available());
entity.setContentType("binary/octet-stream"); // sigh...
return entity;
}
}
I am using Android Volley to cache requests this works fine when I was using GET but I switched to use POST for some reasons. Now I want to cache the same URL with different POST data.
Request 1 -> URL1, POST Data = "Cat=1"
Request 2 -> URL1, POST Data = "Cat=2"
Request 3 -> URL1, POST Data = "Cat=3"
is this can be done with Android Volley
as the Volley.Request.getCacheKey() returns the URL which in my case is the same; this did not work for me.
Instead I had to override getCacheKey() in my child class to return URL+POST(key=Value)
That way I was able to cache all the POST requests made to the same URL with different POST data.
when you try to retrieve the cached request you need to construct the cache key with the same way.
so here is a snapshot of my code:
public class CustomPostRequest extends Request<String> {
.
.
private Map<String, String> mParams;
.
.
public void SetPostParam(String strParam, String strValue)
{
mParams.put(strParam, strValue);
}
#Override
public Map<String,String> getParams() {
return mParams;
}
#Override
public String getCacheKey() {
String temp = super.getCacheKey();
for (Map.Entry<String, String> entry : mParams.entrySet())
temp += entry.getKey() + "=" + entry.getValue();// not do another request
return temp;
}
}
When ever you construct a new request you can use getCacheKey() to search for the cached request first before putting it in the requests queue.
I hope this helps.
Also if you don't want to use one of the existing Request classes you can follow this code (I'm using JsonArrayRequest here, you can use whatever you want)
Map<String, String> params = yourData;
JsonArrayRequest request = new JsonArrayRequest(Request.Method.POST, url,
new Response.Listener<JSONArray>() {
... Needed codes
},
new Response.ErrorListener() {
...
}
){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
return params;
}
#Override
public String getCacheKey() {
return generateCacheKeyWithParam(super.getCacheKey(), params);
}
};
and based on Mahmoud Fayez's answer, here the generateCacheKeyWithParam() method:
public static String generateCacheKeyWithParam(String url, Map<String, String> params) {
StringBuilder urlBuilder = new StringBuilder(url);
for (Map.Entry<String, String> entry : params.entrySet()) {
urlBuilder.append(entry.getKey()).append("=").append(entry.getValue());
}
url = urlBuilder.toString();
return url;
}
