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 have the following CQL apoc query in neo4j that works fine to get response payload from a rest GET request:
CALL apoc.load.jsonParams($uri, {Authorization: $Bearertoken}, null)
YIELD value
UNWIND value.items AS item
RETURN item
However, the uri uses pagenation and the next page uri is present in the response header. Therefore, I need a way to retrieve the response header along with the value. Please let me know if there is a way to do this.
Thanks in advance.
The apoc.load.jsonParams procedure does not support returning the response header.
You can write your own code instead. Here is an article that can help get you started.
I have seen several posts addressing this issue or similar to this issue for requests or GETs. I am not having this problem getting the data from the server, its solely on the POST.
The Errors I get are
The JSON request was too large to be deserialized.
or either
Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property. Parameter name: input
I haven't been able to consistently determine which actions result in which error, but it is predominately the latter one.
In an effort to get the value of the MaxJsonSize value, on the Index method of the controller, I get this data and dump it into a viewbag to write to console on the client side. Every time it comes back at 10k (102400).
If I reduce the data package size, and still serialize as previously, I get no errors.
In fiddler I can inspect the package and all the JSON is deserializable in fiddler, so I don't see an issue in my JSON. Additionally if I console.log(data) chrome sees no problems with it either.
The VM in the controller is the same for both POST and GET. With the exception there is more data with the POST than the GET. To test this I got a huge data set from the server;
GeoJSON data for all 50 states. Following was the result.
GET Content-Length: 3229309 return 200
POST Content-Length: 2975244 return 500
The POST failed in this scenario and returned the second error listed previously.
I only changed the data minimally (one string) and don't know why when sent back its smaller, but the JSON for both the GET and the POST is virtually identical.
I've tried changing the web.config file:
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="2147483644"/>
</webServices>
</scripting>
</system.web.extensions>
I just added this to the end of my config file just prior to
I've also added a parameter in Settings.config
<add key="aspnet:MaxJsonDeserializerMembers" value="2147483644" />
I have also verified that this param loads as part of the application settings in IIS.
Is there something else I can try to change to allow for these large data sets to be sent in a POST.
As a last resort, I was going to pull all of the GeoJSON data out of the POST. However when a user navigates back and they haven't changed what they were mapping, we'd have to find all the GeoJSON data again, causing undue work on the server etc. I thought if I only had to fetch it once that would be best from an efficiency perspective.
I struggled with this too, nothing I changed in web.config helped, despite several SO answers looking relevant. They helped with returning large JSON data, but the large JSON post kept failing. In the end I found this:
increase maxJsonLength for JSON POST and used the solution there, and it worked for me.
Quoting from there :
the MVC json serializer does not look at the webconfig to get the max length (thats for asp.net web services). you need to use your own serializer. you override ExecuteResult and supply you own json serializer. to override the input, create a new JsonValueProviderFactory, then override ValueProvider in the controller to return your new json factory when its a json request.
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.

Thanks for any help.
You're going to need to do something like this: Parsing query strings on Android.
When I try to parse ( http://www.roundmenu.com/webservices/index.cfm?ws=listrst&filter=featured ) webservice in json I encounter issues.
If any one can find out what the problem please let me know.
thanks in advance.
That’s not valid JSON. As usual, it’s useful to validate JSON input via http://jsonlint.com.
That particular JSON input fails to properly escape double quotes (\") inside strings.
Put the response in a json formatter like this one on curiousconcept.com. It yields many errors, does look like it's invalid json.
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>

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.

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.
