Android Question GET method with JSON array

[khwarizmi]

Hi all

I use this code to get data from a url containing JSON array like this :
http://192.168.1.13:3000/cstmrlgn/{"user":"ali","pw":"sss"}

Dim chlog As HttpJob
    chlog.Initialize("checklogin", Me)
    chlog.download2(myurl, Array As String("MyJSON", js))
    ProgressDialogShow("verifying username and password")

always I get error (<pre>Cannot GET /cstmrlgn/</pre> )

thanks in advance

That's not how urls work. You should read the basics here: https://en.wikipedia.org/wiki/URL

If you wish to GET data, you will need to send your parameters in a more standardized way. The most common way is to send as query parameters, like this:

https://www.example.com/checklogin?user=ali&pw=ass

A less common, but perfectly valid if you are sure what the server expects, is this:

https://www.example.com/checklogin/ali/ass

Most likely you will want to use my first example.

I work as part of a team and I have to work with JSON array for input and output.

this url (http://192.168.1.13:3000/cstmrlgn/{"user":"ali","pw":"sss"} ) is working in the normal web browser and in the Postman

Use Poststring instead of download!

As written you are defining the http job wrong.

That's fine, but you're still doing it wrong. Like @DonManfred indicated, if you need to send a json to the server, you should almost certainly do a POST instead. (There are other alternatives, but they are so rare that we can ignore them in this thread.)

this url (http://192.168.1.13:3000/cstmrlgn/{"user":"ali","pw":"sss"} ) is working in the normal web browser and in the Postman

I strongly doubt that. I mean, I believe you when you say it works. However, I don't believe that's what's happening behind the curtain. My best guess is that Postman et al do some automatic conversion. ("Oh, the user entered data like this, la-di-da, I'll just convert it for them so it works, to-de-loo".) You should try to inspect your network traffic to see what really gets sent when you do a request like that.

thanks Sandman and DonManfred, I Use Poststring instead of download, but I get (<pre>Cannot POST /cstmrlgn/</pre>)

Dim job2 As HttpJob
job2.Initialize("job2",Me)
job2.Poststring(myurl,js)

 

[DonManfred]

without knowing the server side script it is hard to give any congrete advice.

"cstmrlgn" seems to be not existent or not reachable.

 

[Sandman]

I have nothing further to add.

Whats the content of js

 

[khwarizmi]

thanks, Now I made a modification to the code and put the web address on the form: http://192.168.1.13:3000/cstmrlgn/checklogin/ali/sss and now it is working
I temporarily postponed research on the subject, but will return to it later.
