webservice要求提交一个带有complex type的request来更新数据库。结构如下：
            <xs:complexType name="CreateUpdateMovieRequest">
                <xs:sequence>
                    <xs:element maxOccurs="unbounded" minOccurs="0" name="ageListForMovie" nillable="true" type="ax25:AgeEntity"/>
                    <xs:element minOccurs="0" name="country" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="director" nillable="true" type="xs:string"/>
                    <xs:element maxOccurs="unbounded" minOccurs="0" name="genderListForMovie" nillable="true" type="ax25:GenderEntity"/>
                    <xs:element maxOccurs="unbounded" minOccurs="0" name="genreListForMovie" nillable="true" type="ax25:GenreEntity"/>
                    <xs:element minOccurs="0" name="imageName" nillable="true" type="xs:string"/>
                    <xs:element maxOccurs="unbounded" minOccurs="0" name="interestListForMovie" nillable="true" type="ax25:InterestEntity"/>
                    <xs:element minOccurs="0" name="language" nillable="true" type="xs:string"/>
                    <xs:element maxOccurs="unbounded" minOccurs="0" name="languageListForMovie" nillable="true" type="ax25:LanguageEntity"/>
                    <xs:element minOccurs="0" name="movieDuration" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="movieFileName" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="movieId" type="xs:int"/>
                    <xs:element minOccurs="0" name="movieName" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="plot" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="releasedDt" nillable="true" type="xs:string"/>
                    <xs:element minOccurs="0" name="synopsis" nillable="true" type="xs:string"/>
                    <xs:element maxOccurs="unbounded" minOccurs="0" name="tagListForMovie" nillable="true" type="ax25:TagEntity"/>
                </xs:sequence>
            </xs:complexType>

看文档上说put内只能放 QByteArray 和 QIODevice，我该怎么做才能上传我要的这个Complex Type
小弟在这里谢过了

没人用过么？？ 有人可以指点一下么=，=

是否用

QNetworkRequest request; request.setUrl(QUrl("http://xxxxxxxxxx/xxxxxxx/xxxxxxxxx")); //设置URL

QByteArray data = "country=1&direction=3&language=7&............." // 设置data？？？

QNetworkReply *rtn = networkManager->put.(request,data);  // 发送put 请求

如果是，那像type是GenderEntity 的这种应该怎么放data去。

感谢回复，不过formdata部分没看懂加入的是什么，看起来是毫无关系的一些东西，可以解释一下吗？

嗯，折腾了一整天，终于搞定了。

简单说下我自己的解决方案的思路：

既然WebService要求request带一个complex type的XML，那我就按照WSDL里说明的Type造一个XML。
用的是QXmlStreamWritter xmlWritter(QByteArray *data); 构造完XML，调用post(request, data); 测试后终于成功了。

这样看来无论webservice要求多复杂结构的XML作为data加入request，都可以用QXmlSreamWritter + QByteArray 来实现。

附带一个参考链接：http://community.freshbooks.com/forums/viewtopic.php?id=4384  这里用的是标准c++库来写XML，比较机械，对于稍微复杂或者带有较多节点的复杂XML写起来工作量就比较大了，所以我考虑用QXmlStreamWritter会更灵活方便

ps：貌似这里人气还是不够旺啊……
