while using http adapter I need to call first service that return XML,
after receiving the response I want to change values and send back to anther service,
how can I do it ?
do http adapter has json to xml function ?
WL adapter will automatically convert XML to JSON for you, however it doesn't have any manual JSON<->XML conversion APIs.
In your case possible solution might be to retrieve XML as plaintext by supplying returnedContentType:"plain" in invocation options. Alter whatever you need using regex/string replace. Use resulting string in 2nd procedure invocation as post body.
Alternatively, you can use 3rd party library to parse/convert/do whatever you need with XML, e.g. http://www.json.org/java/ (more info about how to use it in your adapter - http://public.dhe.ibm.com/software/mobile-solutions/worklight/docs/v506/04_08_Using_Java_in_adapters.pdf)
After checking number of solutions, I state the the http result will be a plain text,
then made a call to java function sending the xml as String, and used
javax.xml to hold and alter the XML.
XPath to retrieve the correct node using org.w3c.dom.*
Hope this will help you too.

Hi i am new to API connect ... i have a use case where i have to merge responses coming from two endpoints in XML format based on certain conditions.
My flow in the assemble section is like this
1) INVOKE
(i make my
first service call
and capture the response
in a custom 'Response
object varibale' -XMLResponse1
2) INVOKE
(i make my
second service call
and here i am not using any
custom 'Response object varibale'
Instead i am using apim.getvaribale('message.body') to get the response
3)GATEWAYSCRIPT
Here i want to write my script for parsing the xml and merging the two responses
and send back the merged response to the consumer
I observed that the xml response is not getting captured in a custom Response object variable when i try to capture it like below
var test1= apim.getvariable('XMLResponse1');
test1.item(0).childNodes
it throws me an exception like this
test1.item is not a function
now for the second response like below where i am not capturing the response in a custom Response object variable it works well
var test2= apim.getvariable('message.body');
My question:
1)How do i capture the xml responses in a custom Response object variable?
2)How can i parse the response into a javascript object? are there any libraries supported in api connect?
Below is the samples found from IBM community. Hope this may help you.
**** Sample XML ****
<Routing>
<partner name="Partner A" key="1">
<from_ID>PartnerA-KEY1-INT</from_ID>
<to_ID>PartnerA-KEY1-EXT</to_ID>
<destination>PartnerA-KEY1-DESTINATION</destination>
</partner>
<partner name="Partner B" key="2">
<from_ID>PartnerB-KEY2-INT</from_ID>
<to_ID>PartnerB-KEY2-EXT</to_ID>
<destination>PartnerB-KEY2-DESTINATION</destination>
</partner>
<partner name="Partner C" key="3">
<from_ID>PartnerC-KEY3-INT</from_ID>
<to_ID>PartnerC-KEY3-EXT</to_ID>
<destination>PartnerC-KEY3-DESTINATION</destination>
</partner>
</Routing>
**** Corresponing Gateway Script *****
var response = apim.getvariable('XMLResponse1.body');
var objType = response.item(0);
var string = objType.getElementsByTagName("partner").item(0).getElementsByTagName("from_ID").item(0).textContent;
output ---> string = PartnerA-KEY1-INT
Why do you want to merge them in a GatewayScript node??
You could merge them in a mapping node, in wich you have 2 variables as input (refered to the output objects of your invokes) and one XML object as output...
If you have to apply some conditions or comparisons, you could do them in the code part of the mapping nodes
A parse server cloud function is defined via
Parse.Cloud.define("hello", function(request, response) {..});
on the response, I can call response.success(X) and response.error(Y), and that sets the http response code and the body of the response.
But how do I define a different code, like created (201)?
And how do I set the headers of the response?
thanks, Tim
You are allowed to return any valid JSON from response.success(). Therefore, you could create an object with fields such as code, message, and value, so you can set the code, give it a string descriptor, and pass back the value you normally would, if there is one. This seems to accomplish what you need, though you will have to keep track of those codes across your platforms. I recommend looking up standard http response codes and make sure you don't overlap with any standards.
For a SP using For Xml returns a xml as response, If this sp was consumed by a WCF receive location, we can specify the Polling as XmlPolling to let adapter keep the responsed xml "as-is". But for a wcf-sql Solicit-Response Send port, It seems no same way to do it. Currently, the best result I can get is let adapter treat the xml response as a CDATA. Like below:
<usp_MySPResponse xmlns="http://schemas.microsoft.com/Sql/2008/05/TypedProcedures/dbo">
<StoredProcedureResultSet0>
<StoredProcedureResultSet0 xmlns="http://schemas.microsoft.com/Sql/2008/05/ProceduresResultSets/dbo/usp_MySP">
<UnNamedColumn0><![CDATA[ <!-- The XML content of sp returned goes here -->
....
Assuming the Stored Procedure uses the FOR XML clause, there are two binding properties you must set for the result to be recognized as Xml:
XmlStoredProcedureRootNodeName
XmlStoredProcedureRootNodeNamespace
It's these two properties that tell the Adapter it's a FOR XML Stored Procedure. These are essentially the same as the legacy SQL Adapter.
Details here: http://msdn.microsoft.com/en-us/library/dd787898.aspx
There is no way around this so your BizTalk Schema must match these values.
Reading the link https://learn.microsoft.com/en-us/biztalk/adapters-and-accelerators/adapter-sql/execute-stored-procedures-having-a-for-xml-clause-in-sql-server-using-biztalk carefully, it says that the request schema must be generated selecting from "Procedures", undeniably not "TypedProcedures". The request message will therefore be in the namespace http://schemas.microsoft.com/Sql/2008/05/Procedures/dbo which is not explicitly mentioned in
https://learn.microsoft.com/en-us/biztalk/adapters-and-accelerators/adapter-sql/message-schemas-for-procedures-and-functions but the action for a "for xml"-typed procedure is specified there. To summarize: A request message is thus:
<YOURSPNAME xmlns="http://schemas.microsoft.com/Sql/2008/05/Procedures/dbo" />
and the port configuration action header is
<BtsActionMapping xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Operation Name="YOURSPNAME" Action="XmlProcedure/dbo/YOURSPNAME" />
</BtsActionMapping>
Note the discrepancy between the request message's namespace and the operation action, only the action has "Xml" in it. And don't forget to specify the (FOR XML) binding parameters, as answered by Johns-305.
I am testing RESTapi with (json format) using (HTTP Request sampler) in jmeter. I am facing problems with the PUT calls for update operation.
The PUT call with parameters don't work at all using (HTTP Request sampler), so now i am using the post body to pass the Json.
How can i pass the extracted values from the previous response to next PUT request in thread group? Passing the 'Regex veritable' to PUT call in Post body don't work, it doesn't take ${value} in Post body.
How do i carry out UPDATE operations using (HTTP Request sampler) in Jmeter?
Check that your regexp extractor really worked using a debug sampler to show extracted value.
Check your regexp extractor is scoped correctly.
See this configuration:
A Variable:
Its use with a PUT request:

Can Flash be used together with SQL? I have a Flash form and I need to connect it to SQL. If there is any example on the net about this topic. I can't find it.
You don't use ActionScript directly with an SQL database. Instead you make http requests from ActionScript to a server, specifying the correct parameters. A typical opensource setup, is a PHP script communicating with a MySQL DB, but you can use Java with Oracle, Ruby with CouchDB, .NET with SQL or any other possible configuration. The important point is that you must be able to call a server script and pass variables... typically a Restful setup.
Once your PHP script has been properly configured, you can use http POST or http GET to send values from ActionScript.
PHP:
<?php
$updateValue = $_POST["updateValue"];
$dbResult = updateDB( $updateValue ); //This should return the db response
echo( $dbResult );
?>
To call this script from ActionScript, you need to create a variables object.
var variables:URLVariables = new URLVariables();
variables.updateValue = "someResult";
The variable name .updateValue, must match the php variable exactly.
now create a URLRequest Object, specifying the location of your script. For this example the method must be set to POST. You add the variable above to the data setter of the request.
var request:URLRequest = new URLRequest( "yourScript.php" );
request.method = URLRequestMethod.POST;
request.data = variables;
Now create a URLLoader and add an event listener. Do not pass the request created above to the constructor, but to the load method.
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onComplete );
loader.load( request );
The handler would look something like this.
private function onComplete( e:Event ) : void
{
trace( URLLoader( e.target ).data.toString() );
}
This example shows how to update and receive a response from a server / db combo. However, you can also query a DB through the script and parse the result. So in the PHP example above, you can output JSON, XML or even a piped string, and this can be consumed by ActionScript.
XML is a popular choice, as ActionScript's e4x support treats XML like a native object.
To treat the response above like an XML response, use the following in the onComplete handler.
private function onComplete( e:Event ) : void
{
var result:XML = XML( URLLoader( e.target ).data );
}
This will throw an error if your xml is poorly formed, so ensure the server script always prints out valid XML, even if there is a DB error.
The problem with this is giving someone a flash file that directly accesses SQL server is very insecure. Even if it's possible, which I have seen SOCKET classes out there to do so for MySQL (though never used it), allowing users to remotely connect to your DB is insecure as the user can sniff the login information.
In my opinion, the best way to do this is to create a Client/Server script. You can easily do this with PHP or ASP.net by using SendAndLoad to send the data you need to pass to SQL via POST fields. You can then send back the values in PHP with:
echo 'success='.+urlencode(data);
With this, flash can access the data via the success field.
I don't personally code flash but I work with a company who develops KIOSK applications for dozens of tradeshow companies, and my job is to store the data, return it to them. This is the method we use. You can make it even cleaner by using actual web services such as SOAP, but this method gets the job done if its just you using it.
You should look into Zend Amf or even the Zend Framework for server side communication with Flash. As far as I know Zend Amf is the fastest way to communicate with PHP ( therefore your database ) also you can pass & return complex Objects from the client to the server and vice versa.
Consider this , for instance. You have a bunch of data in your database , you implement functions in ZF whereas this data is formatted and set as a group of Value Objects. From Flash , you query ZF , Zf queries the database , retrieve & formats your data, return your Value Objects as a JSON string ( for instance ). In Flash, you retrieve you JSON string , decode it and assign your Value Objects to whatever relevant classes you have.
There are plenty of tutorials out there regarding Flash communication with the Zend Framework.
