Geometry to JSON Flex 2.4

FranciscoBereciartu

Hi,

I have a Geometry object result from the Geometry service of ArcGIS Server 10, and I want so send over that Geometry to do another process using a SOE in C# but the goetry is huge my questions are:
1.- Geometry this huge can be sent over using POST or can't be done? if the 1st was true, there is a method in Flex API to converte the geometry to JSON or it has to be manually?


Thanks in advance

Not sure if if makes sense in your case, but one feature that is often overlooked in general is the ability to send a URL that will return geometries instead of the actual geometries. Whether a GP or SOE, depending on your specific use case, you might want to just send a URL to something like (instead of retrieving, parsing, returning those three polygons):

http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer/buffer?geometries={"geometries":[{"x":1469510.0355645495,"y":7499622.6821904825}],"geometryType":"esriGeometryPoint"}&inSR=102100&outSR=102100&bufferSR=4326&distances=10,50,100&unit=9036&unionResults=false&f=json

Again, depending on your specific use case, this might or might not be a good idea 🙂

Thank you for yours answers.

bjorn,

I'm using JSON.encode to encode my Geometry object to pass it to a SOE, but when I encode the geometry the result is liek this {"rings":[[[341839.7316,7715308.5897],...., "spatialReference":{"wkid":31984}} and when I try to do a jsonObject.TryGetJsonObject(...) it gives me an error like it can't be found but all the string arrives because I do TryGetString and all the string arrives, I'm trying to retrevie that object an create an instance of that geometry in C#... am I missing something?? before I create the JSON, the geometry object has more attributes ... the flex builder documentation says in the encode method (Encodes a Flex object into a JSON string. Note that for a graphic, convertToJSON will convert attributes and geometry, but not the symbol) but I don't understand what does this mean (I'm newbie in arcGiS world)

Thanks in advance
