Today, I encountered the problem that Jquery returned json data, and Internet explorer prompted me to download it. When I submitted the data, I returned json data, which was tested in the fire arc. However, Internet explorer always prompted me to save it.

The return value set: the context. The Response. ContentType = “application/json”;

Try: context. The Response. ContentType = “text/XML.” ; failure

Later tried: under the context. The Response. ContentType = “text/plain; Charset = utf-8 ”;

Success!
