I'm trying to get example found from this link to work.
GET
and DELETE
methods are working but I have some issue with PUT
and POST
. I get server replied: Bad Request. With qDebug()
I get this error:
QNetworkReply::NetworkError(ProtocolInvalidOperationError)
To httprequestworker.cpp, I have changed request type to:
request_content.append("Content-Type: application/fhir+json");
Here is my function for getting contents of JSON file from computer and executing the whole input of request for the server:
void MainWindow::on_pushButton_clicked()
{
QString url_str = "http://hapi.fhir.org/baseDstu3/Patient/4705560";
HttpRequestInput input(url_str, "PUT");
QString settings;
QFile file;
file.setFileName("C:/Users/Lauri/Desktop/FHIR/Omia testeja/themostsimplepatientJSON.json");
file.open(QIODevice::ReadOnly | QIODevice::Text);
settings = file.readAll();
file.close();
settings.remove(QRegExp("[\\n]"));
qDebug() << settings;
settings.toUtf8();
input.add_var("key1", settings);
HttpRequestWorker *worker = new HttpRequestWorker(this);
connect(worker, SIGNAL(on_execution_finished(HttpRequestWorker*)), this, SLOT(handle_result(HttpRequestWorker*)));
worker->execute(&input);
}
Here is the simple JSON I want to upload:
{
"resourceType": "Patient",
"text": {
"status": "generated",
"div": "<div xmlns='http://www.w3.org/1999/xhtml'>This is a test patient<a name='mm'/></div>"
},
"name": [
{
"use": "usual",
"prefix": [
"Mr"
],
"given": [
"Teppo",
"Testi"
],
"family": "Testinen"
}
],
"telecom": [
{
"value": "123456789",
"system": "phone",
"use": "home"
}
],
"gender": "male",
"birthDate": "2018-08-21"
}
JSON file should be right because I have been able to POST
and PUT
with postman and other tools. Is there something obvious that I'm missing?
Captures from postman:
With qDebug()
I can see that reading JSON is successful. I have been trying to find solution for ProtocolInvalidOperationError
with no success.
the class HttpRequestWorker
does not support the sending of json, so I will not use it in the example. For this case I will use QNetworkAccessManager
directly:
In the case of PUT you must add the id in the .json, so you can modify the file or do it by code, in this case use the second case:
PUT:
