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) {debuggerif("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;});
