聚合物 2 铁 ajax 与 handleAs=xml 错误？

Question

I have the following code:

<iron-ajax verbose="true" auto method="GET" url="https://localhost/xformupload" handleAs="xml" headers='{"accept" : "text/xml", "mandator" : "xxx", "user" : "xxx", "password" : "xxx"}' params='{"command" : "list"}' on-response="_on_response" last-response="{{response}}"/>

Reviewing this within Chrome debugger the request will be send correctly, also the answer (xml) is correctly. What drives me crazy here is that everything except the handleAs="xml" will be set correctly.

But within the chrome debugger (iron-ajax.html:484) when the request is send - handleAs is always (damned) set as "json".

Looks to me like polymer will not(!) set handleAs attribute correctly!

Or did I miss something?

Answer 1

好的，明白了 - 不能是 handleAs，而是 handle-as。

<iron-ajax verbose="true" auto method="GET" url="https://localhost/xformupload" handle-as="xml" headers='{"accept" : "text/xml", "mandator" : "xxx", "user" : "xxx", "password" : "xxx"}' params='{"command" : "list"}' on-response="_on_response" last-response="{{response}}"/>
