Qt词典搜索

采用阿凡达数据-API数据接口及爱词霸API数据接口实现词典搜索功能，实例字符串搜索接口分别为：中文词组采用“词典”，中文单个字采用“中华字典”，英文或其他字符采用“爱词霸”；
对应的API接口：
http://api.avatardata.cn/CiHai/LookUp?key=[申请的APPKEY]&keyword=[搜索内容]
http://api.avatardata.cn/XinHuaZiDian/LookUp?key=[申请的APPKEY]&content=[搜索内容]
http://dict-co.iciba.com/api/dictionary.php?key=[申请的APPKEY]&w=[搜索内容]

1.字符串搜索分类

void DictLookUpKeyRequest(const QString &strSearchKey)

{

    QString strDictLookupKey = strSearchKey.trimmed();

    if (strDictLookupKey.isEmpty())

    {

        emit DictLookUpKeyFinished(false, "---INVALID_URL---");

        return;

    }

    QString strLookUpUrl = "";

    if (strDictLookupKey.contains(QRegExp("[\\x4e00-\\x9fa5]")))

    {

        //search key contains Chinese character

        if (strDictLookupKey.contains(QRegExp("[A-Za-z0-9]")))

        {

            emit DictLookUpKeyFinished(false, "---NO_SUPPORT---");

            return;

        }

        if (strDictLookupKey.size() >= )

        {

            strLookUpUrl = QString("http://api.avatardata.cn/CiHai/LookUp?key=d19e2a742a7b467c83a63bdd263b371b&keyword=%1").arg(strSearchKey);

        }

        else

        {

            strLookUpUrl = QString("http://api.avatardata.cn/XinHuaZiDian/LookUp?key=175dcbe2c06e49db9eef7f76045ddb55&content=%1").arg(strSearchKey);

        }

    }

    else

    {

        //search other key

        strLookUpUrl = QString("http://dict-co.iciba.com/api/dictionary.php?key=B602AC1E01426961CADF60B71CA97484&w=%1").arg(strSearchKey);

    }

    HttpDictLookUpRequest(strLookUpUrl); //QNetworkRequest

}

2.QNetworkRequest搜索网络请求

void HttpDictLookUpRequest(const QUrl& url)

{

    QNetworkReply *reply = mpManager->get(QNetworkRequest(url));

    connect(reply, &QNetworkReply::finished, this, [this]()

    {

        QNetworkReply* reply = static_cast<QNetworkReply*>(sender());

        reply->deleteLater();

        if (reply->error())

        {

            emit HttpGetRequestFinished(false, "");

        }

        else

        {

            emit HttpGetRequestFinished(true, reply->readAll());

        }

    });

}

3.搜索返回数据处理

void OnDictLookUpResult(bool bFinsihed, const QString& DictLookUpKeyReplyStr)

{

    QString strTextResult = QString("< font color=#6e6e6e >%1</font>").arg(tr("The query word is not entered in the dictionary, please try again later"));

    if (bFinsihed)

    {

        if (DictLookUpKeyReplyStr.contains("</dict>"))

        {

            //iciba search result

            if (!DictLookUpKeyReplyStr.contains("<acceptation>"))

            {

                mpTextEdit->setText(strTextResult);

                return;

            }

            QXmlStreamReader reader(DictLookUpKeyReplyStr);

            while (!reader.atEnd())

            {

                reader.readNext();

                if (reader.isStartElement())

                {

                    if (reader.name().contains("key"))

                    {

                        strTextResult = "";

                        strTextResult.append(QString("< font color=#4a4a4a ><b>%1</b></font>").arg(reader.readElementText()));

                    }

                    else if (reader.name().contains("pos") || reader.name().contains("acceptation"))

                    {

                        strTextResult.append(QString("< font color=#6e6e6e ><br>%1</font>").arg(reader.readElementText()));

                    }

                }

            }

        }

        else

        {

            QJsonParseError jsonParseError;

            QJsonDocument jsonDocument = QJsonDocument::fromJson(DictLookUpKeyReplyStr.toUtf8(), &jsonParseError);

            if (jsonParseError.error == QJsonParseError::NoError)

            {

                QJsonObject jsonObj = jsonDocument.object();

                int returnValue = jsonObj.value("return_code").toInt();

                if (returnValue == )

                {

                    QJsonObject resultJsonObj = jsonObj.value("result").toObject();

                    if (!resultJsonObj.value("words").toString().isEmpty())

                    {

                        //CiHai search result

                        strTextResult = QString("< font color=#4a4a4a ><b>%1</b></font>").arg(resultJsonObj.value("words").toString());

                        strTextResult.append(QString("< font color=#6e6e6e ><br>%1</font>").arg(resultJsonObj.value("content").toString()));

                    }

                    else

                    {

                        //XinHuaZiDian search result

                        QJsonArray resultArray = jsonObj.value("result").toArray();

                        if (resultArray.size() > )

                        {

                            QJsonObject resultArrayJsonObj = resultArray.at().toObject();

                            strTextResult = QString("< font color=#4a4a4a ><b>%1</b></font>").arg(resultArrayJsonObj.value("hanzi").toString());

                            if (!resultArrayJsonObj.value("jianjie").toString().isEmpty())

                            {

                                strTextResult.append(QString("< font color=#6e6e6e ><br>%1</font>").arg(resultArrayJsonObj.value("jianjie").toString()));

                            }

                            if (!resultArrayJsonObj.value("xiangjie").toString().isEmpty())

                            {

                                strTextResult.append(QString("< font color=#6e6e6e ><br>%1</font>").arg(resultArrayJsonObj.value("xiangjie").toString()));

                            }

                        }

                    }

                }

            }

        }

    }

    mpTextEdit->setText(strTextResult);

}
