Qt: How to pass parameters in url to rest api in Qt?

Question

I need to connect to Rest API on the server in Qt and I can get token and authenticate but there is a problem and that is when i'm sending some parameters to Rest API like this: "http//localhost:44444/api/Getmojodi?Code=1234"它返回空響應。 解決辦法是什么？ 參數不在 URL 正文中，只有“用戶名”、“密碼”和“授予類型”在正文中。

QNetworkAccessManager *man1=new QNetworkAccessManager(this);
connect(man1,&QNetworkAccessManager::finished,this,&MainWindow::authenReply);
QUrl url("http://localhost:59444/api/Getmojodi?KalaCode=20101010131310");
const QByteArray basic_authorization =token.toUtf8().toBase64();
//request.setRawHeader(QByteArrayLiteral("Authorization"), basic_authorization);
request.setUrl(url);
man1->get(request);

Answer 1

要將查詢字段添加到 url，我使用QUrlQuery 。 您可以根據需要添加任意數量。

QUrl url("http://localhost:59444/api/Getmojodi");
QUrlQuery query;
query.addQueryItem("KalaCode", "20101010131310");
query.addQueryItem("someParam", someVal);
query.addQueryItem("otherParam", "otherVal");
url.setQuery(query);
request.setUrl(url);
man1->get(request);

對於這個問題，我檢查了 postman 中的API請求，並且有隱藏的標題，我不知道它們，並將這個標題添加到我在 qt 中的請求中，它工作得很好：

QUrl url("http://localhost:59444/api/Getmojodi");

request.setRawHeader(QByteArrayLiteral("Authorization"),token.toUtf8());
request.setRawHeader("Content-Type", "application/x-www-form-urlencoded");
request.setRawHeader(QByteArrayLiteral("User-Agent"),"ApiTest2/1.0");
request.setRawHeader(QByteArrayLiteral("Accept"),"*/*");
request.setRawHeader(QByteArrayLiteral("Accept-Encoding"),"gzip, deflate, br");
request.setRawHeader(QByteArrayLiteral("Connection"),"keep-alive");
request.setSslConfiguration(QSslConfiguration::defaultConfiguration());
QUrlQuery uq;
uq.addQueryItem("KalaCode","20101010131310");
url.setQuery(uq);
request.setUrl(url);
manager->get(request);
