## 场景 ##

前端使用SSM请求后台时提示：

Invalid character found in the request target. The valid characters are defined in RFC 7230 and RFC 3986

前端请求如下

$("#book").submit(function() {
      if($(this).Andrew_Validate("submit_Validate")){
       $("#book > button:submit").attr("disabled","disabled").text("订单提交中...");
       $('#clause').attr("disabled","disabled");
       var actionurl = $(this).attr("action"); //提交路径
       var data = $(this).serialize();
       console.log(data);
       $.ajax({
        async : true,
        cache : false,
        type : 'POST',
        url : actionurl,
        data : data,
        success : function(data) {
         if("200"==data.statusCode){
          //请求成功
          window.location.href = "${ctx}/frontPage/passFlight/GJbookPay.html?orderId="+data.result;
         }
         if("300"==data.statusCode){
          $("#book > button:submit").removeAttr("disabled","disabled").text("下一步，去支付");
          $('#clause').removeAttr("disabled","disabled");
           if(-1==data.result){
           //请求失败处理函数
           webToast(data.message, "middle", "mask", 1000);
           }else{
            var contactName=$("#contactName").val();
            var contactAreaCode=$("#contactAreaCode").val();
            var contactAreaMobile=$("#contactAreaMobile").val();
            var email=$("#email").val();
            var phone=$("#phone").val();
            var contactCookie = $.cookie("bus__contact");
            //将联系人信息存储到cookie中
            if(contactCookie && contactCookie!=""){
                 //查看是否是当前登录用户的填写信息
                 contactCookies=contactCookie.split(";"); //字符分割
                 var tempCookie;
                 for(j = 0; j < contactCookies.length; j++) { 
                 tempCookie=contactCookies[j].split(",");
                  if(tempCookie[4]==phone){
                   var s=contactName+','+contactAreaCode+','+contactAreaMobile+','+email+','+phone;
                   contactCookies.splice(j,1,s);
                   $.cookie('bus__contact',contactCookies);
                 }
                  else{
                 var contactResult=contactCookie+";"+contactName+','+contactAreaCode+','+contactAreaMobile+','+email+','+phone;
                 $.cookie('bus__contact',contactResult);
                  }
                  }
                }
              else{
              var contactResult=contactName+','+contactAreaCode+','+contactAreaMobile+','+email+','+phone;
              $.cookie('bus__contact',contactResult);
              }
             Andrew_Popupwin({
                      dom: "#login_dialog_plug_popupWin", //弹窗内容的布局
                      position: "middle", //位置类型(top，bottom，left，right，middle)
                      effectIn: "bounceInDown", //弹窗显示效果
                      effectOut: "bounceOutDown", //弹窗消失效果
                      maskPosition:"11", //Mask的z-index数值
                      closeBtn: ".login_dialog_plugin_close" //关闭弹窗按钮
                  })
           }
         }
        },
        error : function(err) {
         $("#book > button:submit").removeAttr("disabled","disabled").text("下一步，去支付");
         $('#clause').removeAttr("disabled","disabled");
         //请求失败处理函数
         webToast("请求错误", "middle", "mask", 1000);
        }
       });
      }
      return false;
     });

后台SSM代码如下：

@ResponseBody
     @RequestMapping(value = "/GJbookPayValidate", method = RequestMethod.POST)
     public Map<String,Object> GJbookPayValidate(PiaoHouGJBookInfoPayViewModel model){
      try {
       //登录账户验证部分
       BaseSubjectModel bsm = SubjectUtil.validate(this.getClass(),loginType,"机票预订失败：");
       if(!bsm.isFlag()) {
        return bsm.getJsonResult();
       }
       //业务部分
       return this.service.getGJBookPayValidateJson(model,bsm);
      }
      catch (Exception e) {
       LogService.getInstance(this).debug("机票预订失败："+Status.UNKNOWN_SESSION_EXCEPTION.toString()+e.getMessage());
       return JsonResult.jsonWsReturn(Status.ERROR.getCode(), Status.ERROR.getDescriptionZh(), Status.ERROR.getCode());
      }
     }

在 业务中封装参数的方法：

private static Map<String, Object> setJsonObj(int statusCode, String msg) {
      Map<String, Object> jsonObj = new HashMap<String, Object>();
      switch (statusCode) {
      case 200:
       jsonObj.put("statusCode", "200");
       jsonObj.put("message", msg == null ? "操作成功" : msg);
       break;
      case 300:
       jsonObj.put("statusCode", "300");
       jsonObj.put("message", msg == null ? "操作失败" : msg);
       break;
      }
      return jsonObj;
     }

## 实现 ##

可以确定的是在接口请求与返回数据时出现问题。

仔细观察上面的代码就会发现问题：

第一次请求验证接口时返回的结果是一个对象，再次请求时使用

window.location.href = "${ctx}/frontPage/passFlight/GJbookPay.html?orderId="+data.result;

而data.result是一个对象，显然这样是不行的，修改为：

$("#book").submit(function() {
      if($(this).Andrew_Validate("submit_Validate")){
       $("#book > button:submit").attr("disabled","disabled").text("订单提交中...");
       $('#clause').attr("disabled","disabled");
       var actionurl = $(this).attr("action"); //提交路径
       var data = $(this).serialize();
       console.log(data);
       $.ajax({
        async : true,
        cache : false,
        type : 'POST',
        url : actionurl,
        data : data,
        success : function(data) {
         debugger
         if("200"==data.statusCode){
          debugger
          $.ajax({
           async : true,
           cache : false,
           type : 'POST',
           url : "${ctx}/frontPage/passFlight/GJbookPay.html",
           data : data.result
          });
        
          //window.location.href = "${ctx}/frontPage/passFlight/GJbookPay.html?orderId="+data.result;
         }
         if("300"==data.statusCode){
          $("#book > button:submit").removeAttr("disabled","disabled").text("下一步，去支付");
          $('#clause').removeAttr("disabled","disabled");
           if(-1==data.result){
           //请求失败处理函数
           webToast(data.message, "middle", "mask", 1000);
           }else{
            var contactName=$("#contactName").val();
            var contactAreaCode=$("#contactAreaCode").val();
            var contactAreaMobile=$("#contactAreaMobile").val();
            var email=$("#email").val();
            var phone=$("#phone").val();
            var contactCookie = $.cookie("bus__contact");
            //将联系人信息存储到cookie中
            if(contactCookie && contactCookie!=""){
                 //查看是否是当前登录用户的填写信息
                 contactCookies=contactCookie.split(";"); //字符分割
                 var tempCookie;
                 for(j = 0; j < contactCookies.length; j++) { 
                 tempCookie=contactCookies[j].split(",");
                  if(tempCookie[4]==phone){
                   var s=contactName+','+contactAreaCode+','+contactAreaMobile+','+email+','+phone;
                   contactCookies.splice(j,1,s);
                   $.cookie('bus__contact',contactCookies);
                 }
                  else{
                 var contactResult=contactCookie+";"+contactName+','+contactAreaCode+','+contactAreaMobile+','+email+','+phone;
                 $.cookie('bus__contact',contactResult);
                  }
                  }
                }
              else{
              var contactResult=contactName+','+contactAreaCode+','+contactAreaMobile+','+email+','+phone;
              $.cookie('bus__contact',contactResult);
              }
             Andrew_Popupwin({
                      dom: "#login_dialog_plug_popupWin", //弹窗内容的布局
                      position: "middle", //位置类型(top，bottom，left，right，middle)
                      effectIn: "bounceInDown", //弹窗显示效果
                      effectOut: "bounceOutDown", //弹窗消失效果
                      maskPosition:"11", //Mask的z-index数值
                      closeBtn: ".login_dialog_plugin_close" //关闭弹窗按钮
                  })
           }
         }
        },
        error : function(err) {
         $("#book > button:submit").removeAttr("disabled","disabled").text("下一步，去支付");
         $('#clause').removeAttr("disabled","disabled");
         //请求失败处理函数
         webToast("请求错误", "middle", "mask", 1000);
        }
       });
      }
      return false;
     });
