Incorporating Secured REST Services

KennethLyons

I'm having an issue with incorporating a REST Service that requires a username/password in order to view. I've attempted to use the "Generate Token" option and that has worked for me in the past, however, I'm having no luck this time around.

Is there something that I'm missing when inputting the code? below is the URL with token that was generated from the site.

url="https://www.oagisargissvr.beta.state.pa.us/ArcGIS/rest/services/DMVA_SAFER_AVL/MapServer/1?token=UW1YruC4rYGjqW1seJhog8c4R2IEEdpeY29jpccDxeMOvMxMlZDoE-JJ-zMvluaygFejhkoJnADl7vvPWJr2CNW4yMhH4h4ecowaDm2T8PlZlfBnHftjtSBVl34QRE7Ap1O9MaehAo4iMgKOiNy0_P-950euu8OQ9oVO7jsPVBw.">

I've tried several variations of this (http/https, with/without "1?" before "token") even generated tokens for each variation. I must be missing something because this wasn't that difficult in the past.

thanks in advance for your assistance.

Ken,

As far as the popups I believe the issue is that you have the popupconfig as a child tag of the layer tag and it is suppose to be an attribute of the layer tag.

            <layer label="Fires" type="feature" visible="false" alpha="1.0"                    popupconfig="popups/PopUp_Fires.xml"                    url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/FeatureServer/0"/>

Ken,

Yes, Sorry it should have been "picSymbol2"

KennethLyons

var uvVal1:UniqueValueInfo = new UniqueValueInfo(picSymbol,"HMV");
                            infoArr.push(uvVal1);
                            var uvVal2:UniqueValueInfo = new UniqueValueInfo(picSymbol,"Transport");
                            infoArr.push(uvVal1);

Should the "picSymobol" for Transport read "picSymbol2" as to identify a separate icon for a different value?

Ultimately I'm just not sure how to assign separate icons to different values in the "TYPE" attribute.

Thanks

RobertScheitlin__GISP

Ken,

In the MapManager.mxml find the addLayerToMap function and make the indicated changes:

                    case "feature":
                    {
                        var featureLayer:FeatureLayer = new FeatureLayer(url);
                        featureLayer.addEventListener(FlexEvent.HIDE, featureLayer_hideHandler);
                        featureLayer.alpha = alpha;
                        featureLayer.id = label;
                        featureLayer.name = label;
                        featureLayer.maxAllowableOffset = maxAllowableOffset;
                        featureLayer.outFields = [ '*' ]; // TODO: be smarter
                        featureLayer.token = token;
                        featureLayer.visible = visible;
                        featureLayer.useMapTime = useMapTime;
                        featureLayer.clusterer = clusterer;
                        if (useAMF)
                        {
                            featureLayer.useAMF = (useAMF == "true");
                        }
                        if (mode)
                        {
                            featureLayer.mode = mode;
                        }
                        if (definitionExpression)
                        {
                            featureLayer.definitionExpression = definitionExpression;
                        }
                        if (proxyUrl && useProxy)
                        {
                            featureLayer.proxyURL = proxyUrl;
                        }
                        // example for hard-coding layer symbology, e.g. for pre-10.0 ArcGIS Servers
                        /* if (label == "Traffic Cameras") // the layer label in main configuration file
                        {
                            var picSymbol:PictureMarkerSymbol = new PictureMarkerSymbol("assets/images/i_camera.png",30,30,0,0,0);
                            var rend:Renderer = new SimpleRenderer(picSymbol);
                            featureLayer.renderer = rend;
                        } */
//Added Code
                        if(label == "DMVA Inactive"){
                            var picSymbol:PictureMarkerSymbol = new PictureMarkerSymbol("assets/images/excel.png",30,30,0,0,0);
                            var picSymbol2:PictureMarkerSymbol = new PictureMarkerSymbol("assets/images/ru.png",30,30,0,0,0);
                            var infoArr:Array = [];
                            var uvVal1:UniqueValueInfo = new UniqueValueInfo(picSymbol,"HMV");
                            infoArr.push(uvVal1);
                            var uvVal2:UniqueValueInfo = new UniqueValueInfo(picSymbol,"Transport");
                            infoArr.push(uvVal1);
                            var uvRend:UniqueValueRenderer = new UniqueValueRenderer("TYPE",null,infoArr);
                            featureLayer.renderer = uvRend;
                        }
//End Added Code
                        layerObject.layer = featureLayer;
                        featureLayer.addEventListener(LayerEvent.LOAD_ERROR, layer_loadErrorEvent);
                        featureLayer.addEventListener(LayerEvent.LOAD, layer_loadEvent);
                        map.addLayer(featureLayer);
                        break;
                    }

Also at the top of the MapManager.mxml you need to ensure you have these two imports:

import com.esri.ags.renderers.UniqueValueRenderer;
            import com.esri.ags.renderers.supportClasses.UniqueValueInfo;

So far you have promoted most of my posts on this thread but have not marked it as answered. In case you are not sure how to do this look at this graphic:

Rob,

That did the trick for the popups.

Thanks!

RobertScheitlin__GISP

Ken,

As far as the popups I believe the issue is that you have the popupconfig as a child tag of the layer tag and it is suppose to be an attribute of the layer tag.

            <layer label="Fires" type="feature" visible="false" alpha="1.0"                    popupconfig="popups/PopUp_Fires.xml"                    url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Fire/Sheep/FeatureServer/0"/>

KennethLyons

Rob,

As far the popups, I verified that all the fields are accurate. However, when I click on them, the window does not open. Is this an issue again with the server being 9.3? or does it have to deal with the fact that its secure?

Thanks again.

KennethLyons

Rob,

Yes I have been working in FlashBuilder on the source code this whole time.

Please let me know what I need to do.

Thanks

RobertScheitlin__GISP

Ken,

Setting the symbology in the XML was not introduced until 3.1 in earlier version it has to be done in the code. Do you have access to Flash Builder where I can instruct you where to make the changes in the source code?

RobertScheitlin__GISP

Ken,

That would definitely be the issue but the MAIN issue is that you are using FV 2.5 and it DOES NOT support the layer symbology tags. What do you mean you can not access any of the attributes for that layer? Are you sure you are using the right field names? Have you double checked them against the Rest Service directory?

KennethLyons

Another thought. Could part of the issue be that I cannot access any of the attributes associated with each point. This would explain why the Unique Value Renderer isn't changing anything, because it can't access any values to assign.

If this is part of the problem. how do I go about addressing this?

thanks

KennethLyons

Rob,

I apologize for continuing this thread. It seems like this issue should have been handled by now. But the Unique Value Renderer lines of code aren't changing anything. Is it possible that the issue is steming from another area?

Here is what I have as far as the code goes,

<layer label="DMVA Inactive" type="feature" visible="false" alpha="1" 
                    url="https://www.oagisargissvr.beta.state.pa.us/ArcGIS/rest/services/DMVA_SAFER_AVL/MapServer/2?token=mq3pMZuiWDvMpOJeYoE5XbrWLwLpYVGB4dKeQxzfW7gVtL_YSLqs-YFM7pF8zPqffMWeBU83wjtHuFEm436NgA.."> 
                  <uniquevaluerenderer field="TYPE" fielddelimiter=",">                  
                       <uniquevalueinfo value="HMV" label="HMV">
                            <picturemarkersymbol height="20" width="20" url="assets/images/excel.png"/>                                  
                       </uniquevalueinfo>
                        
                       <uniquevalueinfo value="Transport" label="Transport">
                            <picturemarkersymbol height="20" width="20" url="assets/images/ru.png"/>         
                       </uniquevalueinfo>
                   </uniquevaluerenderer>
                   
             <popupconfig="popups/BFT/800MHz.xml"/>
            </layer>

Is this a function that is available as far back as Flex 2.5? That's the only other thing that I can think of that might cause an issue. If I can get one icon to change, I know I can make the rest work, but so far Ive been unsuccessful.

Thanks again for your assistance.

KennethLyons

Rob,

Based on what you've shown me. Here is what I have come up with so far. However, the icons are not changing when I run the program. Is there something else I'm missing? Does the URL have to be an actual web address?

<layer label="DMVA Inactive" type="feature" visible="false" alpha="1" 
                    url="https://www.oagisargissvr.beta.state.pa.us/ArcGIS/rest/services/DMVA_SAFER_AVL/MapServer/2?token=mq3pMZuiWDvMpOJeYoE5XbrWLwLpYVGB4dKeQxzfW7gVtL_YSLqs-YFM7pF8zPqffMWeBU83wjtHuFEm436NgA..">

                       <uniquevalueinfo value="HMV" label="HMV">

KennethLyons

Rob,

Sorry for the confusion. As I said, this is something that I've never had to do, so I'm not even sure where to start.

Here is the info off of the REST Services page. I believe that this is the info that you're asking for.

I think what I'm looking for is a Unique Value Renderer. The service that I'm attempting to display selects an icon based on 3 fields.
STATUS
TYPE
SECURE_YN

Here is what I've come up with based on what I've read on the link you sent. Please let me know if I'm on the right track

<uniquevaluerenderer>
    <field name="STATUS">
    <field name="TYPE">
    <field name="SECURE_YN">
    <fielddelimiter=",">
</uniquevaluerenderer>
<uniquevalueinfo>
     <value="UNRESPONSIVE,HMV,N" label="assests/images/sleet.png">
</uniquevalueinfo>

REST Service.JPG

RobertScheitlin__GISP

Ken,

You have me seriously handicaped here as you have not given me any info on the layer you want to symbolize... What type of geometry is it are you wanting just a simple single symbol or a unique value renderer based on a field, etc, etc...

KennethLyons

Rob,

That appears to exactly be what the issue is now. The server I am pulling from is not 10.0+.

Do you happen to have an example of this that I can modify? I'm attempting to do this, but having never used these lines of coding previously, I'm basically doing trial and error. And the odds are weighed heavily on "error".

Thanks again for helping me identify the problem

RobertScheitlin__GISP

Ken,

Yes layers that are type feature and not coming from a 10 or greater ArcGIS Server will use a default symbology as the rendering of the features are actually done client side and not on the server. You will have to manually configure symbology for that layer in the main config.xml See Docs here: http://resources.arcgis.com/en/help/flex-viewer/concepts/index.html#/Rendering_and_Symbology_tags/01m30000004w000000/

If the ArcGIS Server supports drawing the symbology client side then the REST Service Directory will have a listing for Drawing Info, like this:

Drawing Info:
Renderer:

Unsupported Symbol

Value: 3Label: Campground

Picture Marker Symbol:

Value: 2Label: Contained Fire

Picture Marker Symbol:

Value: 4Label: Damaged Home

Picture Marker Symbol:

Value: 0Label: Fire Department

Picture Marker Symbol:

Value: 6Label: Mountain

Picture Marker Symbol:

Value: 5Label: Ranger Station

Picture Marker Symbol:

Value: 1Label: Shelter

Picture Marker Symbol:

Transparency: 0
Labeling Info: N/A

KennethLyons

Rob,

I was able to adjust for the problem I was having. The issue went back to a certificate error that wasn't accounted for. Thanks for your help with that.

The issue I'm running into now, is that the icons are not displaying correctly. For example, all the icons are showing up as black dots when they should be showing up as different icons. I've never come across this issue with over services since, in my experience, the icons are defined by the .msd that is published to the server. Is this something that is specific to a "feature" layer type?

I'm able to view the icons correctly when I view these services in ArcDesktop. I'm just not sure where the disconnect is.

Thanks again.

RobertScheitlin__GISP

Ken,

If the token does work for the day you requested it then it is the issue with the ArcGIS Server manger like I said earlier.

KennethLyons

Rob,

I've attached at screen shot of the info I'm putting into the token generator page (minus Username and generated token). I'm not doing this any different that I've done with other tokens in the past. However it's been a while since I've needed to use a token, so either the process has changed, or I'm probably missing something really obvious. I've even just attempted to use the IP address for the application to which I'm attempting to include these services.

I'll get in contact with the host of the server as per your suggestion on the Server Manager settings.

Thanks.

Token.JPG

RobertScheitlin__GISP

Ken,

   Are you generating the token using the exact url/machine name that will be using that token (i.e. if I have http://gis.calhouncounty.org/arcgis/rest/someservice/MapServer in my main config then I need to generate the token using the same fully qualified url "http://gis.calhouncounty.org/arcgis/tokens").

Also you need to check your token settings in Server Manager and make sure that you Lifespan of Long-lived Tokens is what you want it to be:

[TABLE="class: esriDisplayDataTable"]Token Settings

                 [TR]
         Lifespan of Short-lived Tokens:         [TD="class: esriAlignTrailing"]60 minutes[/TD]
       [/TR]
       [TR]
         Lifespan of Long-lived Tokens:         [TD="class: esriAlignTrailing"]1 day
[/TD]
[/TR]
[/TABLE]

KennethLyons

So I initially had figured out what my issue was, but now, I'm running into an issue where the token doesn't appear to provide access correctly, or for the designated amount of time. Could this error be related to the ArcServer software? or am I over looking something simple again?

I keep getting the attached error, even though I have updated the token and inputted the correct URLs.

Any thoughts?

REST Error.JPG

KennethLyons

Rob,

I think I've figured it out. My mistake was that I was using the URL for the REST services when generating the token and not the URL for the site that would be accessing the REST services.

I knew it was probably something simple.

Thanks anyway.

RobertScheitlin__GISP

Kenneth,

You should use the token attribute on your layers tag in the Main config.xml

token�??Token value used for accessing secured ArcGIS Server services. Only applies to layers coming from ArcGIS Server, that is, dynamic, feature, image, or tiled.
