REST Web服务返回的打开PDF [英] Open PDF returned by REST Web Service
问题描述
我有一个JAXB REST Web服务接收请求JSON的POST，并且应该返回一个PDF文档作为响应:

这种二进制文件的文本版本与我看到的那种文本文件有所不同(更多的带问号的字符代替其他字符).
This text version of binary file is different (more question marked characters in place of other ones) from the one I can see opening the binary file from file system with a text editor.
我的问题是:我如何测试发布JSON请求并能够在响应中打开PDF文档的服务?我应该使用其他工具还是构建表单?
My question is: how could I test this service posting the JSON request and being able to open PDF document in the response? Should I use another tool, or build a form?
推荐答案
您只需要使用适当的媒体类型返回pdf字节数组，其余的工作将由浏览器完成.即:
You just need to return the pdf byte array using the proper media type and the browser will do the rest. ie:
@POST
@Path("getReceipt")
@Consumes({ MediaType.APPLICATION_JSON })
@Produces({ "application/pdf" })
public byte[] getReceipt(InputStream incomingData) {
return your_pdf_byte_array;
}
要打开PDF文档，请使用邮递员chrome扩展名
And to open the PDF document use postman chrome extension
