我正在对POST
执行restlet
并需要返回一个zip文件。但是虽然创建的文件是zip,但该方法返回乱码。
我尝试按照建议here:
包装FileRepresentationnew org.restlet.engine.application.EncodeRepresentation(org.restlet.data.Encoding.ZIP, representation);
还尝试添加这样的Produces注释:
@Produces({"application/x-zip-compressed"})
但两者都不起作用。表示返回为乱码字符串,Content-Type
标题保留application/octet-stream
。我错过了什么?
这些是请求标头。请注意Accept-Encoding: gzip, deflate

编辑:我还尝试在创建表示时更改媒体类型:
MediaType mt = MediaType.APPLICATION_ZIP;
FileRepresentation fr = new FileRepresentation(file, mt);
响应内容类型更改为Content-Type: application/zip
,但返回的值仍然是一个乱码字符串。
答案 0 :(得分:1)
正确使用的方法是:
req
所以这应该有用。
使用curl和这样的代码,这就是我所拥有的:
public class MyServerResource extends ServerResource {
@Post
public Representation test(Representation repr) {
FileRepresentation outputRepresentation
= new FileRepresentation(new File("(...)"),
MediaType.APPLICATION_ZIP);
return outputRepresentation;
}
}
另外,以下是我对卷曲的详细模式的看法:
$ curl -X POST http://localhost:8182/test > mycontent.zip
$ unzip mycontent.zip
Archive: mycontent.zip
extracting: test.txt
请注意,如果要在浏览器的下载对话框中配置提示,可以使用标题curl -X POST --verbose http://localhost:8182/test
* Hostname was NOT found in DNS cache
* Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 8182 (#0)
> POST /test HTTP/1.1
> User-Agent: curl/7.35.0
> Host: localhost:8182
> Accept: */*

。
否则,&#34;在Resltet&#34;上启用JSON响应实体的GZIP压缩对应于Restlet对整个响应内容的自动压缩。浏览器支持此功能,可以在显示内容之前直接解压缩内容。我不认为这不是你需要/期望的。如果是这种情况,您可能会对以下链接感兴趣:grunt-notify。
