簡単な説明
Qt自体は、WebServiceを呼び出すためのソリューションであるQtSoapを提供します。ソースコードと例を参照してください：qt-solutions-qtsoap
| 著作権表示：Yiqu、Ersanliは、ブロガーの許可なしに転載することはできません。
ダウンロードしてコンパイルする
ソースコードをダウンロードした後、いくつかの場所を変更する必要があります（私のバージョンはQt5です）。エラープロンプトに従って変更するだけです。非常に簡単です。
コンパイル後、QtSolutions_SOAP-headd.libとQtSolutions_SOAP-headd.dllが生成されます。。。
使用する
QtSolutions_SOAP-headd.libをlibディレクトリにコピーし、qtsoap.hをインクルードディレクトリにコピーします。
プロでライブラリファイルとライブラリディレクトリを追加します。
<span style="color:#000000"><code class="language-Qt">INCLUDEPATH <span style="color:#4f4f4f !important">+=</span> $<span style="color:#4f4f4f !important">$PWD</span>/include

以下では、例として「Get Tencent QQ online status」を取り上げます。WebXml.com.cnを参照してください。これには、携帯電話番号の帰属クエリ、電子メールアドレスの確認、都市の天気予報クエリなど、多数のWebサービスが含まれています。等
例
SOAP 1.1
以下は、SOAP1.1の要求と応答の例です。表示されるプレースホルダーは、実際の値に置き換える必要があります。
