This is my FQL. What it does is it receives the post based on post_id, and also returns if post was made by user or page. User or page is returned based on id of the one who posted the post, which is returned by first FQLQuery.
StringBuilder fqlQuery = new StringBuilder();
fqlQuery.append("SELECT "
+ FacebookGraphApi.FQL_STREAM_SELECT
+ " FROM stream WHERE post_id=\"");
fqlQuery.append(rmtId);
fqlQuery.append("\"");
HashMap<String, String> querys = new HashMap<String, String>();
querys.put("messages", fqlQuery.toString());
querys.put(
"users",
"SELECT "
+ FacebookGraphApi.FQL_USER_SELECT
+ " FROM user WHERE uid IN (SELECT actor_id FROM #messages)");
querys.put(
"pages",
"SELECT "
+ FacebookGraphApi.FQL_PAGE_SELECT
+ " FROM page WHERE page_id IN (SELECT actor_id FROM #messages)");
Now what i would like to do is the same using RESTFB Batch Request API
BatchRequest firstRequest = new BatchRequestBuilder(rmtId)).build();
BatchRequest secondRequest = new BatchRequestBuilder(poster_id).build();
List<BatchResponse> batchResponses =
facebookClient.executeBatch(firstRequest,secondRequest);
These are 2 batches that executes, first one returns the post, and it contains "from", that contains poster_id of the one who posted, but i dont know how to put that poster_id from first batch to second batch so it would return poster information.
Any help would be appreciated, thanks.
Just to post the answer,
first request should contain a name method on which u depend on the other request, and search on second request that depends on first ids like this.
?ids={result=name-of-method:$.data.id}

Similar to: I cannot query my dynamodb table from aws lambda due to wrong filterexpression? and DynamoDB update error Invalid UpdateExpression: An expression attribute value used in expression is not defined
I am trying to code a way to query DynamoDB tables using partial matches on Partition Key / Sort Key in Java.
The DynamoDB table I am trying to access has a Partition key of "Type" (A restricted key word in DynamoDB, I know, but not my choice) and a Sort key of "Id". I know the "Type" but not the full Id, so I have researched the Query method using AWS SDK 2.x source code and have implemented as shown below:
DynamoDBClient dynamoDbClient = DynamoDbClient.builder()
.region(Region.EU_WEST_1)
.credentialsProvider(StaticCredentialsProvider.create(awsCredentials))
.build();
String idKey = "wholeIdKey";
String idValue = "partialIdValue";
String typeValue = "typeValue";
Map<String, String> expressionNames = new HashMap<>();
expressionNames.put("#t", "Type");
QueryRequest request = QueryRequest.builder()
.tableName(tableName)
.keyConditionExpression("begins_with ( " + idKey + ", :" + idValue + " )
AND #t = :" + typeValue)
.expressionAttributeNames(expressionNames)
.build();
QueryResponse response = dynamoDbClient.query(request);
However, when I run this code, I get the following error message:
Exception in thread "main" software.amazon.awssdk.services.dynamodb.model.DynamoDbException:
Invalid KeyConditionExpression: An expression attribute value used in expression is not defined; attribute value: :typeValue
It's as if it's not recognizing the fact that I have told the code use the Expression Attribute Names feature to replace the "#t" with "Type" (Which is a reserved keyword in DynamoDB)
Can anyone help?

https://www.javadoc.io/static/software.amazon.awssdk/dynamodb/2.7.14/software/amazon/awssdk/services/dynamodb/model/QueryRequest.html#expressionAttributeNames--
The name is fine, but you're prefixing both values with ':'. That causes a lookup in ExpressionAttributeValues, which you did not provide.
Never try to write dynamic values directly into the query string.
Your expressionAttributeName looks fine, but you forgot to provide a value for :typeValue so dynamoDB cannot know what to look for.
In addition to what you did, you need to add an expressionAttributeValue where you can provide proper values. See documentation here
Fixed Code for whoever wants it in the future (Thanks to #aherve and #MattTimmermans)

I am using Couchbase 3.2 SDK, to query couchbase server. Like below
QueryResult result = cluster.query(
"SELECT *, Meta().id FROM bucketName USE KEYS ?",
queryOptions().parameters(JsonArray.from("pk")).readonly(true));
The response is like
[{"id":"pk","bucketName":"<binary (21 b)>"}]
My Document is a byte[], How can I get byte[] from the query response.
I have tried
parsing to custom object by doing
result.rowsAs(CustomClass.class)
Also tried
for (JsonObject row : result.rowsAsObject()) {
resposne.put((String) row.get("id"), ((String)row.get("ratingsAndReviewCollection")).getBytes("UTF-8"));
}
but both of them does not return the same doc that i had put.
This thread talks about this but does not give clear solution to this.
GetResult s = cluster.bucket("bucketName").defaultCollection().get("pk");
byte[] doc = s.contentAs(byte[].class);
It is not possible with N1QL, hence the solution in the referenced thread and the solution I provided to the specific question asked.
To pair arguments with results, get creative with reactor. The following is with spring-data-couchbase, where findById() returns Airport. Using the SDK replace findById() with get() which returns a GetResult.
Flux<Pair<String, Mono<Airport>>> pairFlux = Flux.fromIterable(list).map((airport) -> Pair.of(airport.getId(), airportRepository.findById(airport.getId())));
List<Pair<String, Mono<Airport>>> airportPairs = pairFlux.collectList().block();
for (Pair<String, Mono<Airport>> airportPair : airportPairs) {
System.out.println("id: " + airportPair.getFirst() + " airport: " + airportPair.getSecond().block());
}
i am doing api automation of hp-alm using rest assured n java.For test cases with multiple runs, im getting the below response in xml format.I want to know the list of id attributes with its values.
enter image description here
RequestSpecification httpRequest10 = RestAssured.given().cookies(loginCookies).cookies(sessionCookies).queryParam("query", "{cycle-id["+cycleId+"];test-id["+testCaseId+"]}");
Response testRunId = httpRequest10.request(Method.GET,"/qcbin/rest/domains/"+domain+"/projects/"+project+"/runs");
String testRunIdResponseBody = testRunId.getBody().asString();
//logger.info("testRunId Response Body is => " + testRunIdResponseBody);//test run details in xml format
statusCode = testRunId.getStatusCode();
//logger.info("The testRunId status code recieved: " + statusCode);
String stepID= testRunId.xmlPath().from(testRunIdResponseBody).get("**.find {it.#Name == 'id'}.Value");
List<String> runIds = testRunId.xmlPath().from(testRunIdResponseBody).getList("**.find {it.#Name == 'id'}.Value");
logger.info("stepID"+stepID);
Using the above code im able to the first id but not list of ids
I suppose **.find should be replaced with **.findAll:
List<String> runIds = testRunId.xmlPath().from(testRunIdResponseBody).getList("**.findAll {it.#Name == 'id'}.Value");
Using the RallyRestAPI, is there a way to query ScopedAttributeDefinition types? This appears to define custom datatypes in Rally. I am trying to build a data dictionary of the custom types we use in Rally and associate these custom types to the object they are attributes of. (In case that doesn't make sense, here's an example: We have a custom field called Enabler Lead on Rally PortfolioItems. I'd like to query Rally for all custom fields for PortfolioItem and get the Enabler Field, and its metadata, from the Rally REST API.)
I'm using the Java client.
I filed a github issue to add support for the ScopedAttributeDefinition: https://github.com/RallyTools/RallyRestToolkitForJava/issues/19
In the meantime though you can work around it by using the underlying http client directly. This code queries for all projects in your workspace and then finds the type definition for Portfolio Item and then for each project grabs all the custom attribute defs via the scopedattributedefinition endpoint and prints out their hidden/required status.
QueryRequest projectQuery = new QueryRequest("project");
projectQuery.setLimit(Integer.MAX_VALUE);
QueryResponse projectResponse = restApi.query(projectQuery);
QueryRequest typeDefQuery = new QueryRequest("typedefinition");
typeDefQuery.setQueryFilter(new QueryFilter("Name", "=", "Portfolio Item"));
QueryResponse typeDefResponse = restApi.query(typeDefQuery);
JsonObject piTypeDef = typeDefResponse.getResults().get(0).getAsJsonObject();
for(JsonElement projectResult : projectResponse.getResults()) {
JsonObject project = projectResult.getAsJsonObject();
System.out.println("Project: " + project.get("Name").getAsString());
//Begin hackery (note we're not handling multiple pages-
// if you have more than 200 custom attributes you'll have to page
String scopedAttributeDefUrl = "/project/" + project.get("ObjectID").getAsLong() +
"/typedefinition/" + piTypeDef.get("ObjectID").getAsLong() + "/scopedattributedefinition" +
"?fetch=Hidden,Required,Name&query=" + URLEncoder.encode("(Custom = true)", "utf-8");
String attributes = restApi.getClient().doGet(scopedAttributeDefUrl);
QueryResponse attributeResponse = new QueryResponse(attributes);
//End hackery
for(JsonElement customAttributeResult : attributeResponse.getResults()) {
JsonObject customAttribute = customAttributeResult.getAsJsonObject();
System.out.print("\tAttribute: " + customAttribute.get("Name").getAsString());
System.out.print(", Hidden: " + customAttribute.get("Hidden").getAsBoolean());
System.out.println(", Required: " + customAttribute.get("Required").getAsBoolean());
}
System.out.println();
}
Any other info you'd like for each of those custom fields should be accessible just by querying the Attributes collection from the piTypeDef.
I am trying to run Bing search API. I used odata4j and tried the code provided here:
How to use Bing search api in Java
ODataConsumer c = ODataConsumers
.newBuilder("https://api.datamarket.azure.com/Bing/Search")
.setClientBehaviors(OClientBehaviors.basicAuth("accountKey", "{your account key here}"))
.build();
OQueryRequest<OEntity> oRequest = c.getEntities("Web")
.custom("Query", "stackoverflow bing api");
Enumerable<OEntity> entities = oRequest.execute();
After I registered in the bing service, I obtained the key and placed it inside the double quotation in the above code. I got the following error:
Exception in thread "main" java.lang.RuntimeException: Expected status OK, found Bad Request. Server response:

I could not figure out the problem.
All what you need is to set your query like that %27stackoverflow bing api%27
Here is my source code:
ODataConsumer consumer = ODataConsumers
.newBuilder("https://api.datamarket.azure.com/Bing/Search/v1/")
.setClientBehaviors(
OClientBehaviors.basicAuth("accountKey",
"{My Account ID}"))
.build();
System.out.println(consumer.getServiceRootUri() + consumer.toString());
OQueryRequest<OEntity> oQueryRequest = consumer.getEntities("Web")
.custom("Query", "%27stackoverflow%27");
System.out.println("oRequest : " + oQueryRequest);
Enumerable<OEntity> entities = oQueryRequest.execute();
System.out.println(entities.elementAt(0));
You can further try different queries with different filters by keep adding name-value pairs by using .custom("Type of parameter","parameter") of the oQueryrequest object.Say you want to search for indian food but you want only small square images.
ODataConsumer consumer = ODataConsumers
.newBuilder("https://api.datamarket.azure.com/Bing/Search/v1/")
.setClientBehaviors(
OClientBehaviors.basicAuth("accountKey",
"YOUR ACCOUNT KEY"))
.build();
System.out.println(consumer.getServiceRootUri() + consumer.toString());
OQueryRequest<OEntity> oQueryRequest = consumer.getEntities("Image")
.custom("Query", "%27indian food%27");
oQueryRequest.custom("Adult", "%27Moderate%27");
oQueryRequest.custom("ImageFilters", "%27Size:Small+Aspect:Square%27");
System.out.println("oRequest : " + oQueryRequest);
Enumerable<OEntity> entities = oQueryRequest.execute();
int count = 0;
Iterator<OEntity> iter = entities.iterator();
System.out.println(iter.next());
