[SOLVED] QJsonobject value returns NULL

[seethanellai]

HI

I am getting some JSON format info from web API. It is retrieving data properly.

@
QJsonDocument jsonDocument = QJsonDocument::fromJson(jsonAsItem.toUtf8());
QJsonObject jsonObject = jsonDocument.object();@

jsonAsItem is
@{"Id":5,"Name":"name1"}@

but jsonobject returns NULL.

Can any one help me with this?

Hi,

Did you check whether the parsing returns an error ?

Also, can you show the exact content of the json data you are getting ?

Hi,

parseerror errorstring also returns NULL.

This is what i am getting from web API :
@"{"Id":5,"Name":"name1"}"@

[edit: added missing coding tags @ SGaist]

@
QString testData("{"Id":5,"Name":"name1"}");
QJsonParseError parserError;
QJsonDocument doc = QJsonDocument::fromJson(testData.toUtf8(), &parserError);
qDebug() << pareserError.errorString();
qDebug() << doc.object();
@

parserError returns "no error occurred"
and doc.object() returns the correct value

Yes. For me too parse error coming as no error occured and jsondocument.object returns the value. Thanks :)

So you have everything working now ?

[seethanellai]

All the reading part is success. I am able to retrieve the information from jsonobject and array. Thanks for your help.

But having one more doubt. Now i need to call the POST web API for DB insertion. How to do that? Any idea.

I have below web URL (POST method):

http://localhost:49579/api/pdtdata/

I need to pass the below object as a input param to that method:

{
"barcode":"6281002505888",
"descr":"TestPDT",
"doc_type":"GR",
}

Using QNetworkAccessManager::post method
