我使用Qt4将一些数据点发布到OpenTSDB服务器，该服务器不支持分块的HTTP请求。
代码基本上是这样的：
QNetworkRequest request(m_url);
request.setHeader(QNetworkRequest::ContentTypeHeader, QString("application/json"));
request.setHeader(QNetworkRequest::ContentLengthHeader, jsonRequest.toAscii().size());
m_networkAccessManager.post(request, jsonRequest.toAscii());
jsonRequest是一个包含数据点的QString。这段代码不时被调用以将数据上传到服务器，它通常可以正常工作。但是，有时我从openTSDB收到一条错误，指出＆＃34; Chunked请求不受支持。＆＃34;。 这似乎发生在请求变得更大时（并且更大，我的意思是一些KB的数据）。
编辑： 当问题出现时，我已经完成了请求的tcpdump，事实上它并没有被看到被分块：

我认为当请求变大时，Qt正在改变使用分块请求，但事实并非如此。所以当前的问题是：openTSDB中的分块请求是什么？
答案 0 :(得分：10)
我终于找到了它认为我的请求被分块的原因：OpenTSDB内部使用Netty进行网络连接，如果Netty读取一个不包含完整请求的块，那么它被标记为chunked，即使没有转移-Encoding请求中的标头。
有两种可能的解决方案：
请注意，为面向公众的服务器启用分块请求可能不是一个好主意，因为恶意客户端可以发送无限制请求，从而使服务器过载。
