libconnman-qt 连接wifi

Question

您好，目前我正在做一个需要连接到 wifi 的项目，我正在使用 libconnman-qt。

一切顺利（enable/disable wifi，wifi 列表），直到我发现无法连接到 wifi。因此，当我通过以下方式将服务连接到 wifi 时：

mCurrentNetworkService->setPassphrase(ui->linePassword->text());
mCurrentNetworkService->requestConnect();

出现错误："Not Registered"。我不知道发生了什么，因为 lib 没有给我任何线索。或者我错过了哪一步？

您必须先注册一个 "agent" 来响应来自 connman 守护进程的输入请求。这是一个简单的例子。

#include <networkservice.h>
#include <useragent.h>

class Wifi : public QObject {
    Q_OBJECT
public:
    Wifi(QObject *parent = 0) :
        QObject(parent), m_agent(NULL), m_service(NULL) {

        //Register an agent to handle requests from connmand
        m_agent = new UserAgent(this);

        //Connect to UserAgent signal
        connect(m_agent, SIGNAL(userInputRequested(QString, QVariantMap)),
                this, SLOT(agentRequestedUserInput(QString, QVariantMap)));
    }

    ~Wifi() {}

public Q_SLOTS:
    void agentRequestedUserInput(QString path, QVariantMap fields) {
        Q_UNUSED(path)
        QVariantMap reply;
        reply.insert("Passphrase", QString("pass1234"));
        m_agent->sendUserReply(reply);
    }

    void connectToService(QString servicePath) {
        // Add logic to find NetworkService pointer for the service you will connect to

        // pseudo code
        // m_service = findService(servicePath);

        m_service->requestConnect();
    }

private:
    UserAgent *m_agent;
    NetworkService *m_service;
}
