You can use the following software offline on your development pc or any internal computer to emulate any online server for JSON responses.

Example JSON:

dim j as HTTPJob
j.initialize("",Me)
j.download("http://127.0.0.1:5000/myapi")

that means i cant use a code like that, isnt it? with localhost?

Peter Simpson · Feb 17, 2020

Okey then, have you looked at JSONGenerator using the JSON library???

B4X:

dim j as HTTPJob
j.initialize("",Me)
j.download("http://127.0.0.1:5000/myapi")

I guess you should describe it MORE CLEARLY what exactly the goal is. As of now it is not clear to me.

Have you not spotted this???

JSonGenerator

Hi, I need the JSonGenerator to produce JSon like shown below. How can I achieve these examples with list/map/type? I sometimes need 5 or 6 variables within a record, so I though a type would be perfect for this. It would be nice to have a JSonBuilder object :). 1st example...

The example in the linked will give you this JSON output.

Output of the test in the link below:

{
    "Key2": "Value2",
    "Key": "Value"
}
[
    {
        "Record": "1",
        "Key": "Value1"
    },
    {
        "Record": "2",
        "Key": "Value2"
    }
]
[
    {
        "ResponseTime": "\/Date(123)\/",
        "Records": [
            {
                "Record": "1",
                "Key": "Value1"
            },
            {
                "Record": "2",
                "Key": "Value2"
            }
        ]
    }
]

And you can parse the JSON data back with this code

B4X:

Dim parser As JSONParser
parser.Initialize(<text>)
Dim root As Map = parser.NextObject
Dim Key2 As String = root.Get("Key2")
Dim Key As String = root.Get("Key")

Rafi Fahreza · Feb 17, 2020

Peter Simpson · Feb 17, 2020

The search engine on this absolutely fabulous forum does in fact work you know @Rafi Fahreza, just search for it. There is probably more up to date links and information, but I've got other things that I have to start doing now, like starting to cook the dinner..

127.0.0.1 will not work. This points to the device itself, even if you are running it on the emulator.

Start with a real device and put the PC ip address. You will need to first open the relevant port in Windows firewall.

okayy, i checke my computer address via cmd "ipconfig" and it show 192.168.100.9

so should i change the 127.0.0.1 with that address?
