跨域是浏览器沙箱的事,curl没这个限制

这个是要填整那块?@wendal

我不知道你想查什么东西,哪里看出是跨域问题?

在自己搭建的接口平台中,做测试报错的提示

我把图片粘贴到群里了

浏览器访问的时候报错??

入口方法贴来看看

// 获取用户地址修改
@At("/address/?")
@POST
@Ok("json")

public Object updateAddress(int addressId,
       @Param("..") Tbl_weixin_user_address address,
       HttpServletRequest req, HttpServletResponse rsp) {
    // JSONObject j=new JSONObject();
    Json j = new Json();

    rsp.setHeader("Access-Control-Allow-Origin", "*");
    rsp.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
    rsp.setHeader("Access-Control-Max-Age", "3600");
    rsp.setHeader("Content-Type:"," application/json");
    rsp.setHeader("Access-Control-Allow-Headers", "x-requested-with,Authorization");
    rsp.setHeader("Access-Control-Allow-Credentials","true");
    int addressid = courierService.updateaddress(addressId, address);

    // JSONObject json = (JSONObject) JSONObject.toJSON(order);
    if (addressid > 0) {
       j.setInfo("地址修改成功!");
       j.setStatus("0");

    } else {
       j.setInfo("地址修改失败!");
       j.setStatus("1");

    }
    return j;
}

这是调用的接口@wendal

改成这样试试

@Filters(@By(type=CrossOriginFilter.class))
@At(value="/address/?", methods="OPTIONS")
@GET
public Object updateAddress() {}

// 获取用户地址修改
@Filters(@By(type=CrossOriginFilter.class))
 @At("/address/?")
 @POST
 @Ok("json")
public Object updateAddress(int addressId,
       @Param("..") Tbl_weixin_user_address address,
       HttpServletRequest req, HttpServletResponse rsp) {

你是要全部api都跨域吗??

我项目里没有CrossOriginFilter.class

哦, 那你加个动作链的处理器, 或者web.xml配个全局的filter比较

完了,大哥,你说这些,我还不太理解

web.xml配个全局的filter, 这种应该懂吧?

serlvet api里面的filter

这是现在项目的web.xml

加一个类, 然后把它配到web.xml, 放在其他filter之前

谢谢,大神!!!可以了

我靠,楼上的,你搞定了,不是应该,把完整的web.xml文件贴出来么?或者写个总结贴

那我来根据帖子总结下呗.

web.xml完整配置
