SharePoint 2013 如何打包一个应用

o(╯□╰)o 其实蛮简单的，算是献丑了。

SharePoint 2013中的应用其实就是一个基于OpenXML的压缩包，你可以将后缀名从app修改为zip，然后就可以看到里面的结构了。

主要是三个文件：AppManifest.xml、AppIcon.png、AppIcon.png.config.xml。通过OpenXML的工具，还可以查看到他们互相之间还有关系（Relationship）。

然后就简单了，先建立一个可以序列化成XML格式的类AppDefinition（这里的类是最简单的，即不包含权限等信息）。如果你想要更专业些，可以根据SharePoint App Manifest (Schema map)中的XML Schema Definition（XSD）生成一个AppDefinition的类，用来序列化。

[XmlRoot("App", Namespace = "http://schemas.microsoft.com/sharepoint/2012/app/manifest")]
public class AppDefinition {
    [XmlAttribute("Name")]
    public string Name { get; set; }

    [XmlAttribute("ProductID")]
    public string ProductID { get; set; }

    [XmlAttribute("Version")]
    public string Version { get; set; }

    [XmlAttribute("SharePointMinVersion")]
    public string SharePointMinVersion { get; set; }

    [XmlElement]
    public AppProperties Properties { get; set; }

    [XmlElement(ElementName = "AppPrincipal")]
    public AppPrincipal Principal { get; set; }

    [XmlRoot]
    public class AppProperties {
        [XmlElement]
        public string Title { get; set; }

        [XmlElement]
        public string StartPage { get; set; }
    }

    [XmlRoot]
    public class AppPrincipal {
        [XmlElement]
        public RemoteWebApplication RemoteWebApplication { get; set; }
    }

    [XmlRoot]
    public class RemoteWebApplication {
        [XmlAttribute("ClientId")]
        public string ClientId { get; set; }
    }
}

然后通过XmlSerializer即可将实例化后的AppDefinition（definition）序列化为AppManifest.xml了。

AppDefinition definition = new AppDefinition() {
    Name = Guid.NewGuid().ToString(),
    ProductID = Guid.NewGuid().ToString("B"),
    Version = "1.0.0.0",
    SharePointMinVersion = "15.0.0.0",
    Properties = new AppDefinition.AppProperties() {
        Title = title,
        StartPage = launchUrl
    },
    Principal = new AppDefinition.AppPrincipal {
        RemoteWebApplication = new AppDefinition.RemoteWebApplication {
            ClientId = Guid.NewGuid().ToString("B"),
        }
    }
};

using (XmlWriter writer = XmlTextWriter.Create(partStream, new XmlWriterSettings() { Encoding = Encoding.UTF8, Indent = true })) {
    XmlSerializer serializer = new XmlSerializer(typeof(AppDefinition));
    serializer.Serialize(writer, definition);
}

最后用System.IO.Packaging下的Package类，打包就可以了。

using (Package package = Package.Open(stream, FileMode.Create)) {
    PackagePart manifestPart = package.CreatePart<AppDefinition>(new Uri("/AppManifest.xml", UriKind.Relative), "text/xml", definition);
    PackagePart iconPart = package.CreatePart<string>(new Uri("/AppIcon.png", UriKind.Relative), "application/wsp", path);
    PackagePart configPart = package.CreatePart<AppPartConfig>(new Uri("/AppIcon.png.config.xml", UriKind.Relative), "text/xml", config);

    package.CreateRelationship(manifestPart.Uri, TargetMode.Internal,
        "http://schemas.microsoft.com/sharepoint/2012/app/relationships/package-manifest");
    manifestPart.CreateRelationship(iconPart.Uri, TargetMode.Internal,
        "http://schemas.microsoft.com/sharepoint/2012/app/relationships/manifest-icon");
    iconPart.CreateRelationship(configPart.Uri, TargetMode.Internal,
        "http://schemas.microsoft.com/sharepoint/2012/app/relationships/partconfiguration");
}
