(Visual FoxPro) ITIDA Create Canonical JSON

See more Egypt ITIDA Examples

Demonstrates creating the canonical (ITIDA) version of a JSON document. The document in the example is the one at https://sdk.invoicing.eta.gov.eg/files/one-doc.json

Note: This example requires Chilkat v9.5.0.92 or greater.

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* Note: This example requires Chilkat v9.5.0.92 or greater.
* (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSb = CreateObject('Chilkat.StringBuilder')

* This is the file at https://sdk.invoicing.eta.gov.eg/files/one-doc.json
lnSuccess = loSb.LoadFile("qa_data/itida/sdk.invoicing.eta.gov.eg/files/one-doc.json","utf-8")
IF (lnSuccess = 0) THEN
    ? "Failed to load input file."
    RELEASE loSb
    CANCEL
ENDIF

* Convert the contents of sb to the ITIDA canonical form.
* Always pass utf-8 for the 2nd arg.
loSb.Encode("itida","utf-8")

lcCanonical = loSb.GetAsString()

? lcCanonical

* Output: 
* "SomeValue""DELIVERY""APPROACH""SomeValue""PACKAGING""SomeValue""DATEVALIDITY""2020-09-28T09:30:10Z"........."TOTALAMOUNT""5191.50""EXTRADISCOUNTAMOUNT""5.00""TOTALITEMSDISCOUNTAMOUNT""14.00"

* Let's verify we got the correct result.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbExpected = CreateObject('Chilkat.StringBuilder')
lnSuccess = loSbExpected.LoadFile("qa_data/itida/sdk.invoicing.eta.gov.eg/files/one-doc-serialized.json.txt","utf-8")
IF (lnSuccess = 0) THEN
    ? "Failed to expected output file."
    RELEASE loSb
    RELEASE loSbExpected
    CANCEL
ENDIF

* Compare our computed canonical string with the expected result.
IF (loSb.ContentsEqualSb(loSbExpected,1) = 1) THEN
