I'm using the HTTP component to search the Twitter API. Everything is working and I am receiving data back, but I can't seem to access the json object I am receiving. How do I get the data? http.BGResultString is empty and I only know I am receiving data because of the output of http.SessionLogFilename ->

I forgot to add that I am using:

http.SynchronousRequest with http.UseBgThread =1

(Jun 20 '13 at 15:28) jamesblake

(This problem was resolved earlier in private email.)

The solution has to do with a misunderstanding of the API. When the http.UseBgThread is set to False, an HTTP method call runs synchronously and returns a result upon completion (such as a string, bool, HttpResponse object, etc.). However, when the http.UseBgThread is True, the method is started in a background thread and it returns immediately. The return value should be ignored. Once the background task completes, the return value can be obtained from the property or method that corresponds to the return type of the method. For example, the QuickGetStr method returns a string, therefore the async result is available in the BgResultString property. Here's a list of return types and the corresponding property/method used to access the return value after an async method completes:

string: BgResultString property
byte array: BgResultData property
HttpResponse object: BgResponseObject method
bool: BgTaskSuccess property
int: BgResultInt property

Note that the HttpResponse object is returned by a method call, not a property.
