How can i get only index name from response generated by calling _cat/indices using java. Using EntityUtils i am getting the response as string which gives me information in the way how it looks when called using CURL command. I am using rest low level client for fetching the response.
String responseBody = EntityUtils.toString(response.getEntity());
How should i process the responseBody to get only index name ?
ClusterStateResponse response = client.admin().cluster().prepareState().execute().actionGet();
String[] indices = response.getState().getMetaData().getConcreteAllIndices();
You will get the list of indices.

I am trying to connect to a REST API (Not my own so I can't fix their issues) but when I send a GET request, Rest Assured is reprocessing my URI causing the call to fail.
Here is the code to build the request:
Call rest = new Call("https://rest.test.com"); // Custom class to simplify REST calls.
JSONObject searchCriteria = new JSONObject();
searchCriteria.put("textSearchType", "SEARCHNAME");
searchCriteria.put("textSearchString", "joe blow");
String header = "Lead Inline Quick Search";
StringBuilder resource = new StringBuilder("/api/v1/search?");
resource.append("searchCriteria=")
.append(URLEncoder.encode(searchCriteria.toString()))
.append("&header=")
.append(URLEncoder.encode(header));
System.out.println("REST call: " + resource.toString());
rest.get(resource.toString(), 200); // Perform a get on the query, expect a 200 response
When I look at the output, the request is correct:
REST call: /api/v1/search?searchCriteria=%7B%22textSearchString%22%3A%22joe+blow%22%2C%22textSearchType%22%3A%22SEARCHNAME%22%7D&header=Lead+Inline+Quick+Search
However when I look at the debug for Rest Assured, it reprocesses the request causing the call to fail:
Request method: GET
Request URI: https://rest.test.com/api/v1/search?searchCriteria=%257B%2522textSearchString%2522%253A%2522joe%2Bblow%2522%252C%2522textSearchType%2522%253A%2522SEARCHNAME%2522%257D&header=Lead%2BInline%2BQuick%2BSearch
Note:
'{' is correctly converted to '%7B' from the Net encoding and looks right in the resource, but Rest Assured then further converts all the '%' to '%25' making the json invalid ({ becomes %257B).
The '+' in the header is converted to '%20' for some reason. While technically the same, there is no reason to "fix" it.
If I don't encode the values when building the resource, the get call fails because it sees the spaces.
IllegalArgumentException-Invalid number of path parameters. Expected 1, was 0. Undefined path parameters are: "textSearchString":"joe blow","textSearchType":"SEARCHNAME".
So what is the proper way to encode the values? Or get Rest Assured not to monkey with the string it's sent?
The comment from #Hypino put me on the right track.
Adding .urlEncodingEnabled(false) to the .given() did not change the results (call was still double processed). But adding .setUrlEncodingEnabled(false) to the RequestSpecBuilder() gave the correct results.
private RequestSpecBuilder build = new RequestSpecBuilder().setUrlEncodingEnabled(false);
The logged call and the actual call are now the same:
REST call: /api/v1/search?searchCriteria=%7B%22textSearchString%22%3A%22joe+blow%22%2C%22textSearchType%22%3A%22SEARCHNAME%22%7D&header=Lead+Inline+Quick+Search
Request method: GET
Request URI: https://rest.test.com/api/v1/search?searchCriteria=%7B%22textSearchString%22%3A%22joe+blow%22%2C%22textSearchType%22%3A%22SEARCHNAME%22%7D&header=Lead+Inline+Quick+Search
I want to write a JUnit class for a REST endpoint.
This is my REST method. It works fine.
#POST
#Path("create")
#Produces(APPLICATION_JSON)
public String create(#QueryParam("parentId") String parentId, #QueryParam("name") String name) {
//do sth.
return "{\"status\": \"SUCCESS\"}";
}
Now my JUnit test looks like that, which doesn't work, because I don't know how to POST my data in the right way:
#Test
public void testCreate() {
Client client = ClientBuilder.newClient();
WebTarget wt = client.target(REST_MENU_URL + "create");
String queryParams = "parentId=1&name=NEW_JUnit_NEW";
// In the line below, I want to POST my query parameters, but I do it wrong
Response response = wt.request().post(Entity.entity(queryParams, APPLICATION_JSON), Response.class);
// The response has a 500, because the query parameters are all NULL!
assertEquals("Http code should be 200", 200, response.getStatus());
}
So how do I have to change the line with the 'Response' to make it work?
The problem is, that the query parameters (parentId and name) don't get transmitted (response = wt.request().post(...)).
I tried to POST form parameters too, but no success here either. Just like that:
Form form =new Form().param("parentId", "4").param("name", "NEW_JUnit_NEW");
Response response = wt.request().post(Entity.entity(form, APPLICATION_JSON), Response.class);
Thanks,

Check out the Jersey Client documentation, in particular section 5.3.4 on targeting resources.
Query parameters form a part of the URI of the resource, they're not part of the body of the document posted to the resource. You're seeing null in your resource because you're not filling in the query parameters in the URI, you're posting them as the body. You need to tell Jersey to put them in the URI...
WebTarget wt = client.target(REST_MENU_URL + "create").queryParam("parentId", 1).queryParam("name", "NEW_JUnit_NEW");
You'll also need to ensure that your POST request sets the Accept header to allow application/json (by calling the accept(...) method after calling request()) and you're going to need to construct some kind of Entity to pass to the post(...) method - the problem here is that your resource is not consuming the entity body but the client API expects you to send something - this is a code smell which suggests your API is not particularly ReSTful. You can probably get away with some kind of empty body constructed from an empty string. It should look a bit like this...
Response response = wt.request().accept(MediaType.APPLICATION_JSON).post(Entity.text(""))
Alternatively, you could look into converting your API so that it accepts a JSON document and move the query parameters into that document.
I am using the library http-request, from https://github.com/kevinsawicki/http-request
I need to make a GET request to server and get response code and response body separately, given a request.
How can I do that using this lib?
There is only examples retrieving one of them, like :
String response = HttpRequest.get("http://google.com").body();
System.out.println("Response was: " + response);
and
int response = HttpRequest.get("http://google.com").code();
Store the HttpRequest object in a variable
HttpRequest request = HttpRequest.get("http://google.com");
Invoke what you need
request.body();
request.code();
(It's weird to get the response body on a request object...I don't like this library.)
I'm trying to use Yahoo Content Analysis using a file containing text as input. So every character and length is possible.
This code works with a simple text String (no special characters, short text) however when I use longer texts or special characters I get a Bad Request error (HTTP 400) sometimes with an error message like "no viable alternative at character '['" or without an error message.
I encode every request and HTTP Post shouldn't have any limit as to the length.
Does the Yahoo service place a limit on the length of the request and/or are there any characters that it can't handle?
Any help to help this work is appreciated!
Here's my code (using commons-httpclient):
String fileInput = FileUtils.readFileToString(f);
StringBuilder builder = new StringBuilder();
builder.append("http://query.yahooapis.com/v1/public/yql?");
System.out.println(fileInput);
builder.append("q=")
.append(URLEncoder.encode("select * from contentanalysis.analyze where text='"+ fileInput +"'" , "UTF-8"))
.append("&format=json");
final String postUrl = builder.toString();
HttpClient client = new HttpClient();
PostMethod method = new PostMethod(postUrl);
// Send POST request
int statusCode = client.executeMethod(method);
I think the problem is that while you are sending the request as an HTTP POST, the YQL query and text are all included in the URL. YQL does not really have a way for you to make HTTP POST requests directly, so I can think of a couple options:
Directly use the Content Analysis web service with an HTTP POST (docs)
Create a custom YQL data table which uses the <execute> tag to run custom JavaScript which could do the POST (example)
Of these options I think the former would be easier.
I want a java way to extract the parameters of a URL regardless the way these parameters are written in it, in the regular way like( https://www.facebook.com/Doly.mohamed.Smile9?ref=stream&hc_location=stream ) it's so easy because all i have to do is :
URL url = new URL("www.blabla....etc");
String query = url.getQuery();
try{
String [] params = query.split("&");
for(int i= 0 ; i < params.length; i++){
String [] split = params[i].split("=");
parameters.put(split[0], split[1]);
}
}catch(NullPointerException ex){}
so the parameters values would be :
key = ref value = stream , key = hc_location value = stream
but what shall i do if the URL has parameters written in another way or if the URL does't has it's parameters written in it like in the case of the doPost() way.
and is there is a way to get the extraPathInfo from a URL without using servlets?
You could do that easily with Apache's HTTP utils.
URIBuilder uriBuilder = new URIBuilder(uriString);
List<NameValuePair> urlParameters = uriBuilder.getQueryParams();
String uriWithoutParameters = uriBuilder.clearParameters().toString();
Now you could, for example, easily convert the GET request to a POST request, using other classes from the http utils API.
There is a difference between GET and POST urls
In GET url, parameters are part of URL and in POST they are part of Request-body.
So in POST, the URL may or may not contain the request params, and unless you don't have them in the URL its not possible to extract.
The POST request method is designed to request that a web server
accept the data enclosed in the request message's body for storage.1
It is often used when uploading a file or submitting a completed web
form.
So unless you have the POST request's body. Its difficult to extract the Parameter.
Typically you need HTTP request parameters on HTTP server side. Java HTTP server will parse the request and pass it as ServletRequest object to Servlet.service method. ServletRequest has methods to access the request parameters.
