C++ 谷歌分析在C++；桌面应用程序

我正在尝试将Google Analytics tracking添加到我的C++/Qt桌面应用程序中。要做到这一点，我需要进行http访问

http://www.google-analytics.com/__utm.gif

如此处所述：

我的URL看起来像：

http://www.google-analytics.com/__utm.gif?utmwv=5.2.5&utmac=UA-XXXXXXXX-1&utmhn=prot-on.com&utms=1&utmn=1763710005&utmcc=__utma%3D265465294.163654595.1362420921.1362420921.1362420921.1%3B&utmp=%2Freallyallheaders.html&utmcs=-&utmr=-&utmip=127.0.0.1&utmul=es-es&utmfl=-&utmje=-&utmsr=1920x1080&utmhid=957274494

这是我的源代码：

qint64 currentTimestamp = QDateTime::currentMSecsSinceEpoch()/1000;
if (this->timeOfFirstVisit == 0)
    this->timeOfFirstVisit = currentTimestamp;
if (this->timeOfPreviousVisit == 0)
    this->timeOfPreviousVisit = currentTimestamp;

QTextStream（&googleAnalyticsRequestUrl）遗憾的是，谷歌没有官方的Qt库可用。不过，我建议您查看他们的Google Analytics API（目前处于测试阶段）
这还表示，即使您的请求无效且未正确处理，它也将始终返回200。他们更可能支持您使用这个测试版API，然后反向工程他们的javascript直接使用它

编辑：再看看您的代码，最好立即从QUrl开始，使用QUrl添加查询项，这样Qt会注意正确的编码和所有这些。
解决方案是打开一个套接字，正如我在这个PHP库中所做的：

我粘贴我的源代码：

qint64 currentTimestamp = QDateTime::currentMSecsSinceEpoch()/1000;
if (this->timeOfFirstVisit == 0)
    this->timeOfFirstVisit = currentTimestamp;
if (this->timeOfPreviousVisit == 0)
    this->timeOfPreviousVisit = currentTimestamp;

QString googleAnalyticsRequestUrl;
QTextStream(&googleAnalyticsRequestUrl) << "http://www.google-analytics.com/__utm.gif"
<< "?utmwv=5.2.5"
<< "&utmac=" << TRACKING_ID
<< "&utmhn=" << HOST_NAME
<< "&utms=" << this->sessionNumberOfQueries
<< "&utmn=" << QString::number(qrand()) //this->generateRandomUTMN()
<< "&utmcc=__utma%3D" << this->domainHash
    << "." << this->sessionId
    << "." << this->timeOfFirstVisit
    << "." << this->timeOfPreviousVisit
    << "." << currentTimestamp
    << ".1%3B"
<< "&utmp=" << QString(QUrl::toPercentEncoding(pageUrl))

QTextStream（&googleAnalyticsRequest）这里有一个小类（包含在单个文件头中），用于从Qt应用程序向Google Analytics发送测量事件：


当然，请记住遵循谷歌的隐私政策，不要发送个人识别信息，知情同意，并提供用户选择退出……/P>你能直接从浏览器调用你的URL吗？如果这样调用，它是工作的，并且只有在从C++代码中调用时才失败？同样的问题是来自T的响应。服务器，您发出的这个GET请求可以200吗？@user1204395，在这种情况下，我会说您的问题不在C++/Qt代码中。在对代码进行更多工作之前，我会关注通过浏览器获得成功的GET。响应总是200（尽管参数是虚构的，但无论如何返回200）。我已编辑了我的帖子以添加更多信息。感谢您的回答！检查我看到的内容此库将打开一个套接字并发送请求（与我的问题格式相同）你能给我看看你的工作代码吗？就在上周，我正在考虑将分析集成到我的Qt应用程序中，在我发现beta api后，我有点停止了研究。
