I wondered if anyone knows how best to unmarshall a response from a JAX-RS/Jersey client that is returning a response from paypal. The response is URI encoded in name/value pairs. I ask because I've already written some code that unmarshalls a google geocode response, given a class hierarchy it automagically transforms the JSON response into objects, but alas I've not been able to do similar with this simpler problem.
TIMESTAMP=2011%2d06%2d03T13%3a22%3a17Z&CORRELATIONID=f708c43c1d078&ACK=Success&VERSION=56%
Thanks for any help.
You're going to need to do something like this: Parsing query strings on Android.

I am using the google/cloud-dialogflow library for php.
I can not get the data from $queryResult->getFulfillmentMessages(); I don't know how.
I have tried:
json_decode($queryResult->getFulfillmentMessages()->serializeToJsonString(), true);
But it shows me a error. I hope you can help me.
This solution worked for me. The response that is received from the queryResult is a protobuf repeated field. The payload that is required to be extracted can be accessed by calling the first element of the repeated field and serializing it to JSON string then decoding it.
json_decode($queryResult->getFulfillmentMessages()[0]->serializeToJsonString(), true);
This will give the payload in array format using which you can perform your operations on it.
I am developing ios app which is getting data from Google endpoint ,the data is base 64 encoded on the server to a custom java object, which is then returned by the endpoint method.
On the iOS side I am able to receive the data and print the data using the generated client code.
I am facing a problem and I am unable to decode the data back in to the GTL**** endpoint auto generated class.
The decoded data shows up with some hex numbers:
My Code:
let respo2 = GTLDecodeBase64(responce) as? GTLEndpointStatusCollection
I also tried decoding using the swift classes:
let respo = NSData(base64EncodedString: responce, options: NSDataBase64DecodingOptions(rawValue: 0))
The input is base64 encoded : rO0ABXNyABNqYXZhLnV0aWwuQXJyYXlMaXN0eIHSHZnHYZ......
The desired output should have been readable data,
but instead im getting:
<aced0005 73720013 6a617661 2e757469 6c2e4172 7261794c.....
I even tried encoding, decoding the base64 decoded data with NSUTF8
but no use.
What am I doing wrong? Is it possible for data encoded on Server in Java (with custom Java objects) to be decoded back ? (I understand Google endpoint does the serialization/deserialization in between)
Thanks in advance.
You should use JSON for serialization rather than manually converting the object to a bytestring and base64 encoding it. If you are using the Endpoints libraries this is automatically done for you, simply by returning the object in your method. See the docs here for an example and the rest of the Endpoints docs for more details. To consume the API you can use the generated iOS libraries which also do this for you as per the examples here. You won't actually see any JSON unless you inspect the HTTP traffic or use the API Explorer.
It sounds like you might just be doing more work than is needed by pre-encoding the object, rather than just letting Endpoints do it for you. If you really need to manually serialize an object to some property you can use a library on the Endpoints side like Jackson to serialize the object to a string property and NSJSONSerialization on the client to convert it back to an object.
I'm not able to receive plain text using RestyGWT. A very simple test service looks like this:
#GET
#Consumes(MediaType.TEXT_PLAIN)
#Produces(MediaType.TEXT_PLAIN)
void test(MethodCallback<String> callback);
On the client side I always get:
Response was NOT a valid JSON document
Looking at the HTTP response I'm seeing that content type is set correctly:
Content-Type:text/plain
What's the problem? Why RestyGWT tries to parse this as JSON? Am I doing smth wrong?
If you will use TextCallback instead of MethodCallback<String> you won't get this error.
It will set Accept header automatically to text/plain, so you don't have to use #Produces adnotation in your async interface.
Well, RestyGWT is a Json library, AFAIK it is not made to handle plain text, or XML, or anything else. "foo" isn't a valid Json data, should be ["foo"] or {"stuff": "foo"}.
Indeed, in our Rest API, we tried to send pure text (an id), but we finally made a simple object wrapping the id.
I'm really new with all this Scala/Spray. With some testing I was able to get parameters from a Get request using the parameters function. However I'm trying to fetch some parameters sent from a POST request on the body of the request. It seems like parameters function is unable to fetch those values.
As an example, I'm trying to get this values "name=john&lastname=smith" from the post request body. What is the best option to get these values?
Thank you
You could use [Form-Field-Filters] to extract parameters from POSTs
[Form-Field-Filters] https://github.com/spray/spray/wiki/Form-Field-Filters
Indeed, the parameters directive only handles things actually in the query-string and not parameters in the body of the request. To get things out of the body, you'll need to use the content directive and then unmarshal the content.
This spray-user thread may be helpful, as it includes some unmarshalling code doing precisely what you're looking for.
As of recent Spray versions, you need to use the Unmarshaller for FormData.
I am working with the iPhone SDK and I have to process a webservice response I receive from an external service.
The response data consists of an XML string that was UTF8-encoded to a byte array.
This byte array is converted to string
This string is put into a XML wrapper element
The wrapper is returned via an HTTP response
Therefore I need to know how to convert the response data back to the XML string it used to be. Unfortunately, I cannot change the way my response is created, so I have to deal with it somehow.
Example of the raw data I get from the webservice:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body><ExportBytesResponse xmlns="http://knowledgepark-ag.com/webservices/">
<ExportBytesResult>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</ExportBytesResult>
</ExportBytesResponse></s:Body>
How do I get back my old xml string representation hidden inside these raw bytes?
Any help is highly appreciated, I feel just stupid right now for not being able to come up with a solution.
Best Regards,
David
ExportBytesResponse is Base64 encoded, so you must first decode that node using something like this.
That will give you an NSString containing the XML. Then you can use NSXMLParser to parse your data.
