C#
Get Stock Order
1. getStockOrder.cs
We will first import these five packages as they are required to run the solution.
Step 1. Create class file to store content of the web response.
2. GetStockOrder.aspx.cs
We will first import these 13 packages as they are required to run the solution.
Code in Common
Step 1. We would first have to check if the user id and password are already stored inside the session. If the user id and password are stored, the solution will automatically populate into the user id and pin textbox. This is to provide convenience for the users as they do not need to manually type their user id and password repeatedly. Else, if the user id and password are not stored yet, we would then store them inside the session.
Step 2. The next step would be to store the details entered by the user. If the user id, password, and OTP already exist in session, users would not need to enter them again (refer to common stuff).
Step 3. Create the URL which would be posted to the server. User inputs need to be stored in the class created, and serialize into JSON format. In this function, both the header and content are needed.
Step 4. After creating the URL, we would post the URL to the server, and store response. The URL is being sent using a web request function, and a response will be send back from the server. The response need to be deserialized first into the ‘getStockOrder’ class.
Step 5. Next step would be to obtain the error code. If error code is ‘010000’ which means invocation successful, the solution would populate the attributes of the ‘getStockOrder’ class into the label(s). If error code is '010041', it means that the OTP has expired, and we will use the newOTP() function to prompt the user for their OTP again. Else, we will display the ErrorText and ErrorDetails.
The newOTP() function can be referred to under Common Stuff Section
