下载由java webservice(POST)流式传输的pdf [英] Download a pdf streamed by a java webservice (POST)
问题描述
我有一个通过POST方法调用的web服务:
I have a webservice that is called by POST method :
@Path("/ficheAction/")
@POST
@Consumes({ MediaType.APPLICATION_JSON })
@Produces("application/pdf")
public Response ficheAction(final ParamSyntheseFicheActionDto paramSyntheseFicheAction) throws EngineException {
[...]
return Response.ok(output.toByteArray(), "application/pdf")
.header("content-disposition", "attachment; filename = " + name + ".pdf").build();
}
此网络服务使用我的js中的参数(Json):
This webservice use the parameters (Json) from my js :
[...]
$.ajax({
url : webServiceUrl,
//
type : "POST",
// Content type to send to the server
contentType : "application/json; charset=utf-8",
data : pData,
dataType : "json",
success : pCallback,
cache : false,
});
webservice接口工作,但在客户端,导航器不会打开文件( pdf)。
The webservice seams to work, but on the client side, the navigator doesn't open the file (pdf).
我用GET测试而不是POST(简化属性),它可以工作,但不能在POST ...
当我看看chrome调试中web服务的响应,我可以看到响应以%PDF-1.5开头......但是下载没有开始...
I've test with GET instead of POST (simplifying the attributes), and it works, but not in POST... When i look at the response of the webservice in the chrome debug, i can see that there is a response starting with "%PDF-1.5"... But the download does not start...
我做错了什么?
推荐答案
你应该使用GET方法。
You should use GET method.
下载文件,不要使用ajax只需通过简单的链接调用你的web服务。
To download the file, do not use ajax just call your webservice by simple link.
<a href="http://your-server.com/ficheAction">Download</a>
或者使用那个简单的js脚本:
Or use that simple js script:
window.open("http://your-server.com/ficheAction");
