mule - Flow Vars getting lost after Facebook Authorize in MuleStudio -


i have simple flow authorize facebook , post message. 

<flow name="drupal-esbflow2" doc:name="drupal-esbflow2">     <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" doc:name="http"/>     <set-variable variablename="facebookmsg" value="#[message.inboundproperties['msg']]" doc:name="variable"/>     <facebook:authorize config-ref="facebook" doc:name="authorize"/>     <set-session-variable variablename="accesstokenid" value="#[flowvars['oauthaccesstokenid']]" doc:name="get oauthaccesstokenid"/>     <facebook:publish-message config-ref="facebook" msg="#[flowvars['facebookmsg']]" profile_id="100001574667695" accesstokenid="#[sessionvars['accesstokenid']]" doc:name="publish message"/>     <json:object-to-json-transformer doc:name="object json"/> </flow>

the idea want hit endpoint localhost:8082?msg=mymessage. want safe inboundproperties['msg'] in flow variable , use in facebook connector. seems variables gets lost in transport...

i have read known issue (mule facebook - flow variable), there no walk around or something?

well answer sort of alludes to, seems authorize mp intended called in complete isolation of other logic , return access token id via http:response-builder. client responsible sending access token id flow other processing:

<flow name="authorizationandauthenticationflow">     <http:inbound-endpoint host="localhost" port="8080" path="oauth-authorize"/>     <facebook:authorize/>     <http:response-builder status="200">         <http:set-cookie name="accesstokenid" value="#[flowvars['oauthaccesstokenid']]"/>         <set-payload value="you have authorized connector. access token id #[flowvars['oauthaccesstokenid']]"/>     </http:response-builder> </flow>

i can sort of see why, makes architect app in specific way.

the other options use "state" parameter. depends on on types of data you're in flow vars. example:

<facebook:authorize state="#[flowvars.myvalue]"/>

this returned in callback inbound property can retrieved via:

#[message.inboundproperties['state']]

etc.

alternatively @ persisting values, possibly in mule object-store.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
