Multiple POST requests using HTTPUtils

[COBRASoft]

Hi,

I’m using HTTPUtils with POST to communicate with webservices. This works fine as long as I POST 1 at a time, wait for the response and the post the next one.

Is there a way to use POST with multiple requests at the 'same' time?

Here is an example of what I try to do now, but only the first request is dealt with.

    '--- Countries
    btnCachCountry.SetBackgroundImage(Design.bmpRefresh)
    Dim objMap As Map: objMap.Initialize: Shared.AddLoginLanguage(objMap)
    Dim objJSon As JSONGenerator: objJSon.Initialize(objMap)
    HttpUtils.PostString("CountryList", Shared.CountryListURL, objJSon.ToString, Shared.ContentType)

    '--- VehicleBrands
    btnCachVehicleBrand.SetBackgroundImage(Design.bmpRefresh)
    Dim objMap As Map: objMap.Initialize: Shared.AddLogin(objMap)
    Dim objJSon As JSONGenerator: objJSon.Initialize(objMap)
    HttpUtils.PostString("VehicleBrandList", Shared.VehicleBrandListURL, objJSon.ToString, Shared.ContentType)
    '--- VehicleBrandModels
    btnCachVehicleBrandModel.SetBackgroundImage(Design.bmpRefresh)
    Dim objMap As Map: objMap.Initialize: Shared.AddLogin(objMap)
    Dim objJSon As JSONGenerator: objJSon.Initialize(objMap): objMap.Put("CRBR_ID", Shared.EmptyGuid)
    HttpUtils.PostString("VehicleBrandModelList", Shared.VehicleBrandModelListURL, objJSon.ToString, Shared.ContentType)
    '--- VehicleColors
    btnCachVehicleColor.SetBackgroundImage(Design.bmpRefresh)
    Dim objMap As Map: objMap.Initialize: Shared.AddLoginLanguage(objMap)
    Dim objJSon As JSONGenerator: objJSon.Initialize(objMap)
    HttpUtils.PostString("VehicleColorList", Shared.VehicleColorListURL, objJSon.ToString, Shared.ContentType)
    '--- VehicleTypes
    btnCachVehicleType.SetBackgroundImage(Design.bmpRefresh)
    Dim objMap As Map: objMap.Initialize: Shared.AddLoginLanguage(objMap)
    Dim objJSon As JSONGenerator: objJSon.Initialize(objMap)
    HttpUtils.PostString("VehicleTypeList", Shared.VehicleTypeListURL, objJSon.ToString, Shared.ContentType)

Greetings,
Sigurd

As far as I know, HTTPUtils will not accept another request until the first is dealt with.
Also, even if you manage to do this, how will you distinguish between the responses (if they arrive out of order).

By the requested URL

By the requested URL

But the response will be out of order, you will not know which requested URL to use.
Unless the webserver responds with an identifier, you will not know which data has been POSTed successfully.

Good point .

Erel? Any ideas here?

You can not submit a new job while an existing job runs.

Currently HttpUtils supports jobs with multiple GET requests or jobs with a single POST request.

If you must send multiple POST requests then you have three options:
- Modify HttpUtils / HttpUtilsService and change the GET requests handling to send POST requests.
- Store the POST requests in a List and send them one after another (when the previous one finishes).
- Don't use HttpUtils. Use HttpClient directly.

COBRAsoft,

How did you solve this issue?

I am having the same dillema. To initialize my app I have some posts that will return the data for the app, and it is getting out of sequence etc.

Thanks,

This thread is a bit old. It is better to start a new thread for this question (and also use HttpUtils2 instead of HttpUtils).
