我正在尝试向我的firebase应用程序发送“PATCH”请求。据我所知,QNetworkManager不支持“Patch”请求。
如何发送“PATCH”请求?
答案 0 :(得分:6)
所以我们很清楚,QNetworkAccessManager中没有名为“patch”的方法 因此我使用了“sendCustomRequest”但使用了QBuffer。因为QNetworkManager需要一个QIODevice对象。
QString destination="";
currentNode.replace(QString("/").append(latestNode),"");
destination
.append(host)
.append(currentNode)
.append(".json");
QString jsonString=QString(QString("{").append("\"").append(latestNode).append("\"").append(":").append("\"").append(str).append("\"").append(QString("}")));
QNetworkRequest request(destination);
request.setHeader(QNetworkRequest::ContentTypeHeader,
"application/x-www-form-urlencoded");
qDebug()<<jsonString;
QBuffer *buffer=new QBuffer();
buffer->open((QBuffer::ReadWrite));
buffer->write(jsonString.toUtf8());
buffer->seek(0);
manager->sendCustomRequest(request,"PATCH",buffer);
qDebug()<<"posted";

尝试:
QNetworkAccessManager* manager = new QNetworkAccessManager();
QNetworkRequest request("http://<domain>/<path>/");
QHttpMultiPart* multipart = new QHttpMultiPart();
//... Add your data in multipart
manager->sendCustomRequest(request, "PATCH", multipart);

由于QNetworkAccessManager
不隐式支持PATCH,因此我创建了以下类QNetworkAccessManagerWithPatch
。用它代替QNetworkAccessManager
,您将拥有与patch()
,post()
等相同的put()
3种变体。

或直接从此处获取代码:(另存为QNetworkAccessManagerWithPatch.h
)
