QUESTION
I am using C++Builder 10.4.2 with the 64bit compiler. I am trying to parse the nested JSON file below so the "US.NYSE" values are in a TJSONArray, and then loop through them to get each array value. My code does not place the "US.NYSE" into an array. Can you show how to place "US.NYSE" into a TJSONArray? Currently, I can't test the for loop, is this for loop set up correct?
ANSWER
Answered 2021-May-20 at 21:53You have a misunderstanding of how JSON works. I suggest you review the syntax defined by the JSON standard available at https://www.json.org.
There is no array in the JSON you have shown. Arrays are denoted with [] brackets. Objects are denoted with {} braces. So, the top-level JSON value is an Object, the "data“ value is an Object, and the "US.NYSE" is an Object. Thus, the 2 ParseJSONValue() calls will both return a TJSONObject, not a TJSONArray.
There is no need to call ParseJSONValue() the 2nd time, since those inner TJSONObjects are already parsed by the 1st ParseJSONValue() call and are accessible inside of the value hierarchy ofMyjsonFile. Simply typecast the return value of GetValue() to TJSONObject* when accessing those values.
Also, you need to delete the value that is returned by ParseJSONValue() to avoid a memory leak.
Try this instead:
QUESTION
I am using the Jackson library to deserialize JSON. In the JSON I have a few custom fields whose values can be anything, so I am trying to use the @JsonAnySetter and @JsonAnyGetter to obtain the values. The fields and values within the JSON can be duplicated and I would like to obtain everything from the JSON and store it within the map. However, the direct Jackson derealization is storing the last value if there are duplicates in the key.
I have a large JSON file that has many events. I am reading the file event-by-event so that the whole JSON file is not stored within memory. After reading a single event, I check the type of event, based on which I assign it to a different POJO. Following is my sample JSON file consisting of 2 events.

I have a JSON file that I am converting to XML using the JAXB. I am reading the JSON using the Jackson then I am converting them to XML using the JAXB Marshalling process. The elements in JSON can be random user extension so I am using the @JsonAnyGetter to store it into MAP then I am using the adapter to convert them to XML elements.
I just wanted to know how can I skip the addition of the OuterElement or Parent element however I would like to retain the ÌnnerElementor Child element. Is there aJAXB` way of doing it or else what can I do to achieve the following desired result?

And if we run the function on azure portal, it also will not show mess code ???. No matter in logs or in output.
So we do not need to worry about that, the mess code ??? show in local logs may caused by coding problem of logs console.

QUESTION
I know there are a lot of toturials, questions etc and I was working on it at the past weeks but couldn't figure it out.
I am developing an Android app that I want to send an email to some email address, using my gmail account.
I have read all the Google Developers Documentation and tried all the examples but still can't achieve it.
1. First of all - do I have to own a G Suite account? it doesn't say that I do, but the Gmail Api overview is under G Suite section??
If I don't need a G Suite -
2. Is this the right guide to send mail by app?
If so
3. How can I get the Gmail service? I opened a project in console.developers.google and got the OAuth 2.0 Client IDs json file, but I couldn't find an explanation how to use it in Android to get the credentionals.
Please, I know those are big question but I am desperate for help. Please give me any answers or correct links (that I haven't visit yet...). I also will appreciate help via chat / mail etc.
Thanks
EDIT 8/10 my code right now:
Main Activity calls AsyncMail
AsyncMail.java
...ANSWER
Answered 2020-Oct-01 at 15:22I will try to answer your multiple question
No, you don't need a G Suite account to use the Gmail API, you can do it with a normal gmail account.
The guide that you linked is fine, just think that inside an app or in a console, the API works over HTTPs request with a REST architecture, therefore you can use the API in any platform that support HTTP requests.
This last bit will depend highly on the architecture you are using, and take into consideration that I'm not an Android expert. But the "difficult" part will be to get the authorization from the user, but I believe you can do it normally with Java.
QUESTION
I'm trying to extract a query as a csv file. I tried to use copy with pg-query-stream to execute the query but I'm facing this error:
error: bind message supplies 1 parameters, but prepared statement "" requires 0
when removing copy from the query it works fine with the placeholders also if I provided a query with copy and no placeholders it works fine.
ANSWER
Answered 2020-Sep-08 at 00:02I think you're mixing together two features.
pg-query-stream returns the rows as stream, there's no need to use copy in the select there. Just use a simple select, then pipe the results to a filestream.
