Question

我正在尝试使用/ template / {contentId}的URI模板声明处理OpenRasta中的多部分文档的POST，但它失败了。配置是

ResourceSpace.Has.ResourcesOfType<Content>().AtUri("/content/{contentId}").HandledBy<ContentHandler>().RenderedByAspx("~/Views/ContentView.aspx").And.AsJsonDataContract();

处理程序方法如下：

public OperationResult Post(string contentId, IEnumerable<IMultipartHttpEntity> entities) {...}

我正在使用以下curl命令来测试

./curl -v -F myPartName=@./hello.txt http://localhost:10247/content/id-1

如果我从URI模板中删除“{contentId}”并相应地修改处理程序，POST工作正常。

有关如何解决的任何想法？日志文件如下。谢谢 - 罗兰岛

从日志中，您可以看到多部分编解码器正在键/值处理模式中使用。在该模式下，正在解析multipart的内容而不是分配IEnumerable，这肯定是该编解码器的问题。

我在https://github.com/openrasta/openrasta-core/issues/32

添加了修复此问题的错误

与此同时，您可以让多部分编解码器根据需要反序列化内容（您可以通过简单地将DTO或输入参数映射到表单实体的名称来使用，OpenWrap将允许您将表单数据分配到标准属性和IFile或Stream for files）。

或者，根据您的需要，您可以通过覆盖依赖注册器来取消注册密钥/值mutlipart编解码器，并让对象注册正常工作。

如何在OpenRasta中使用form / prefix / {suffix}的URI模板处理多部分POST？
