服务器不支持jsonp怎么请求json数据

Answer 1

跨域请求吗？设置一个拦截器， extends HttpService implements Filter
代码块：
private static final long serialVersionUID = 1L;
public void init(FilterConfig filterConfig) throws ServletException {
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletResponse httpResponse = (HttpServletResponse) response;
httpResponse.setHeader("Access-Control-Allow-Origin", "*");
httpResponse.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE");
httpResponse.setHeader("Access-Control-Max-Age", "1800");
httpResponse.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept,auth_token");
httpResponse.setHeader("Access-Control-Allow-Credentials", "true");
chain.doFilter(request, httpResponse);
}

Answer 2

做一个代理服务里，后台把服务器的数据处理下，转化成jsonp格式。
