Android Question How to enter a curl command as an HTTPS request

Your api key most likely has the following syntax "xxxx: yyyy"

Put your first part ( xxxx ) in j.Username
and the second part ( yyyy ) in j.Password


Now, of course without credential right i have this message:

ResponseError. Reason: Unauthorized, Response: {"detail":"Authentication credentials were not provided."}
{"detail":"Authentication credentials were not provided."}

Hi MarcoRome
Many thanks for the quick reply, I don't suppose you have the full code so I could try it, I am a novice at most things to do with B4A so just having your snippet isn't much use to me to get the full understanding

I believe the Curl -U bypasses the need for a password and whilst the API is structured as you say "xxxxxxxxxxxxxxxxxx:" there's nothing after the colon, I have tried but getting major java errors

Hope you can help and I thank you for your patience

It will be easier to help you if you post the errors.

Do yo have a link with documentation ? & in attachment ( as say Erel ) paste the Error pls

That would translate to

yes that's how I've done the j.username j.password the errors I'm getting are ass follows, as I've stated many times I'm a novice please be gentle

- 28 - The old http SDK is not available by default. This will cause problems with native libraries such as Google Maps who rely on the old SDK. To enable it: https://www.b4x.com/android/forum/t...ar-error-in-android-9-pie.103247/#post-649875

You should use OkHttpUtils2 instead of HttpUtils2. Pay attention to the deprecation message. It is important.

Thanks Erel that seems to work (ish)
I now don't get any errors but the following

ResponseError. Reason: , Response: {"detail":"Authentication credentials were not provided."}
{"detail":"Authentication credentials were not provided."}

So I'm obviously doing something wrong here's my code, the only thing I've missed out is the API_Key

Dim j As HttpJob
j.Initialize("", Me)
j.Username = "sk_live_xxxxxxxxxxxxxxxxxxxx"
j.Password = ""
j.Download("https://api.octopus.energy/v1/electricity-meter-points/1460001714995/meters/15P0459914/consumption/")
Wait For (j) JobDone(j As HttpJob)
If j.Success = True Then
Log(j.GetString)
Else
Log(j.ErrorMessage)
End If
j.Release

I suggest to post the Documentation

You might want to do a quick test with your ordinary browser by going to this address:


Obviously adjust the api key. If it's a standard user/password mechanism, and it's a GET that's used, it should work.

Hi Sandman
That works as expected, thanks, as my meters aren't connected yet I'm getting null values back as I'd expected

What I want to extract using the API is the consumption api, and then a view of every 30 minute period throughout the day as my kwh price changes each half hour and anything I may find useful

The Developer Docs can be found here

Looks like the current (as is) HttpUtils2Service.bas allows only for two configurations when sending username/password combos:
1) Both username AND password are set, pass along username and password credentials (via ExecuteCredentials)
2) Otherwise pass no username/passwords via Execute

Looking at the Git source Execute calls ExecuteCredentials with both username and password set to Null.

Solutions:
1) Don't use the OkHttpUtils2 library. Download source here https://www.b4x.com/android/forum/t...putils2-httputils2-source-code.82632/#content and modify to allow blank password (in HttpUtils2Service.bas, in the SubmitJob method, change the And evaluation to an Or)
2) Make a wish to allow blank password and still process request via ExecuteCredentials (with password set to Null) and see if Anywhere Software provides a permanent solution to the issue (that can be enjoyed by everyone in future B4X versions). Note: This depends on the underlying technology used to allow for a blank password. Otherwise the only option left is solution#1.

Update: Solution #3. Do both 1 and 2.

Try

Or Solution#4, wait for someone smarter to come up with a work around that is a lot simpler (no library fudging required). Now it just needs Base64 encoding

In that case it might work to not supply the username and password and instead modify the url like I did above.

It's worth a try to see if the underlying OkHttp3 library properly parses that type of URL. If it does, that would be a really easy work-around. If not, @MarcoRome's solution (with my slight modification) should definitely work (and would work on all platforms, no matter what underlying library is used). BTW, this forum rocks and I need more coffee.

The last solution seems to work, thank you every one who's helped

Hi, I have got an query as to why when i ask for local rates (without having to pass the username) I can 'parser the data but when I have to add the extra code to pass the username (API_Key) it gets the data but does enter my parser routine.

Sub Download
Dim Job As HttpJob
Dim httpText As String
httpText="https://api.octopus.energy/v1/produ...fs/E-1R-AGILE-18-02-21-E/standard-unit-rates/"
Job.Initialize("job1", Me)
Job.Download(httpText)
End Sub

Sub JobDone(job As HttpJob)
If job.Success = True Then
Select job.JobName
Case "job1"
Dim parser As JSONParser
parser.Initialize(job.GetString)
Dim from As String
Dim tim0 As String
Dim tim1 As String
Dim exV As String
Dim inV As String
Dim root As Map = parser.NextObject
Dim results As List = root.Get("results")

The above works and I can put the data in my table okay, whereas the following gets the data but doesn't enter the Sub routine Sub JoneDone(job as HttpJob)

Sub Download
Dim basicAuth As String = "sk_live_xxxxxxxxxxxxxxxxxxxx:" '
Dim su As StringUtils
Dim authInfo = su.EncodeBase64(basicAuth.GetBytes("UTF8"))
Dim job As HttpJob
job.Initialize("", Me)
job.Download("https://api.octopus.energy/v1/electricity-meter-points/1411105400005/meters/16P0547786/consumption/")
job.GetRequest.SetHeader("Authorization", $"Basic ${authInfo}"$)
Wait For (job) JobDone(job As HttpJob)
If job.Success = True Then
Log(job.GetString)
Else
Log(job.ErrorMessage)
End If
'job.Release
End Sub

Sub JobDone(job As HttpJob)
If job.Success = True Then
Select job.JobName
Case "job1"
Dim parser As JSONParser
parser.Initialize(job.GetString)
Dim from As String
Dim tim0 As String
Dim tim1 As String
Dim cons As String
Dim root As Map = parser.NextObject
Dim results As List = root.Get("results")
