关于web_custom_request函数的一些问题（望指点）

我在录制HTTP/WEB脚本回放的时候，有一段脚本代码
/*这些表示提交发表的问题~*/
/*下面是发表内容为test，标题为test1的疑问，账号是：F001*/

web_custom_request("StudyPlan_Student_Tutor_Index,App_Web_tutor_index.aspx.fdeda029.ashx",
            "URL=http://192.168.11.2:88/lgsoft30/ajaxpro/StudyPlan_Student_Tutor_Index,App_Web_tutor_index.aspx.fdeda029.ashx",
            "Method=POST",
            "TargetFrame=",
            "Resource=0",
            "RecContentType=text/plain",
            "Referer=http://192.168.11.2:88/lgsoft30/StudyPlan/Student/Tutor_Index.aspx?Plan_ID=H0000056",

            "Mode=HTML",
            "EncType=text/plain; charset=utf-8",
         "Body={\"content\":\"<DIV>TEST1</DIV>\"}",
            LAST);

      web_reg_find("Search=Body",
            "Text=1",
            "NotFound=EMPTY",
            LAST);

      web_custom_request("StudyPlan_Student_Tutor_Index,App_Web_tutor_index.aspx.fdeda029.ashx_2",
            "URL=http://192.168.11.2:88/lgsoft30/ajaxpro/StudyPlan_Student_Tutor_Index,App_Web_tutor_index.aspx.fdeda029.ashx",
            "Method=POST",
            "TargetFrame=",
            "Resource=0",
            "RecContentType=text/plain",

            "Body={\" Plan_ID\":\"H0000056\",\"UserID\":\"F001\",\"postTitle\":\"TEST\",\"
postContent\":\"<DIV>TEST1</DIV>\"}",
            LAST);

      /*发表成功~*/

录制时第一个web_custom_request函数，服务器返回的值：

我的分析是，第一个请求是验证提交的数据是否合理，然后第二个是提交数据给服务器，
成功则服务器返回1.
在执行回放的时候，日志服务器返回的日志则是

Action.c(339): 警告: 带有参数分隔符的字符串“"content":"<DIV>TEST1yguggyuygu</DIV>"”不是参数。
Action.c(339): “http://192.168.11.2:88/lgsoft30/ajaxpro/StudyPlan_Student_Tutor_Index,App_Web_tutor_index.aspx.fdeda029.ashx”(RelFrameId=1)的 t=162304ms: 178 个字节响应标头

在这俩个函数里没有需要关联的地方，Plan_ID=H0000056是正确的，不需要关联，为什么俩个web_custom_request的正文里没有返回数据并且没有提交成功呢？在运行查看器里会观察到错误的页面，本人知识有限，不知道怎么解决，望高手指点一二！

楼主解决问题了吗

icebelle · 发表于 2014-11-27 17:23:24

楼主这个问题解决没啊，我的也是返回的为空值呢，提交了参数但是实际上参数都没插入数据库

wangchao6656 · 发表于 2010-5-26 11:09:28

好，我试试，如果解决了这个问题，我再告诉你~多谢了~

skyzhu · 发表于 2010-5-26 11:04:38

推荐 fiddler2 ，本地代理式软件，HTTP专用
简单易用，而且很清晰

wangchao6656 · 发表于 2010-5-26 10:44:48

脚本发出去的HTTP请求能看到，手动发出去的HTTP请求该怎么看呢？

skyzhu · 发表于 2010-5-26 10:12:03

对比一下你自己手动操作和脚本发出去的整个HTTP请求有什么区别吧

wangchao6656 · 发表于 2010-5-26 09:33:05

是不是web_custom_request函数要怎么设置才能正常返回值呢？我录制的脚本中，很多地方回放的时候都没有返回值，检查了一下，不是关联的问题~

wangchao6656 · 发表于 2010-5-25 19:08:11

我录制中用到的web_custom_request函数，为什么它提交数据给服务器的时候，服务器总是返回空值。正常来说是不会返回空值的。

wangchao6656 · 发表于 2010-5-25 19:01:52

修改了参数化的格式也不行，服务器还是返回空值~

skyzhu · 发表于 2010-5-25 16:54:22

恩，这个问题是重点~~~
发出去的BODY脚本认为是参数了，没当字符串

云层 · 发表于 2010-5-25 16:41:07

简单来说由于你返回的数据包是用{}来做的，而这个内容又正好是参数化的标志，所以会脚本回放出错，你修改一下参数化边界的格式就行了

别的问题没看，只看了脚本回放的错误

以下是我用Sniffer抓包工具获取到的与服务器HTTP通讯的过程，只看加粗部分就可以知道他的内容了

把
<DIV>TEST1</DIV>
换成
%3cDIV%3eTEST1%3c%2fDIV%3e
试试
你要抓的是HTTP协议从本机到服务器的内容是什么，其他没什么看的

wangchao6656 · 发表于 2010-5-25 11:49:25

NewPost在后台的定义如下：

AjaxPro.Utility.RegisterTypeForAjax
   [AjaxPro.AjaxMethod]
//以上俩行能声明该函数能被前台调用
public static string NewPost(string Plan_ID, string UserID, int UserType, string PostTitle, string PostContent)
{
      lgzx_SSPQuestion_BLL SSPQuestion_BLL=new lgzx_SSPQuestion_BLL();

      SSP_Function AFunction = new SSP_Function();
      string NewPostContent = AFunction.insertPic(PostContent);
      int Retint = SSPQuestion_BLL.Add_SSPQuestion_BLL(Plan_ID, UserID, UserType, PostTitle, NewPostContent);
      return Convert.ToString(Retint);
}
SSPQuestion_BLL.Add_SSPQuestion_BLL为自定义的后台存储提交内容的函数~

wangchao6656 · 发表于 2010-5-25 11:46:59

开发前台的代码是：var RetVa= StudyPlan_Student_Tutor_Index.NewPost(Plan_ID,UserID,2, postTitle,postContent).value;通过传入参数到后台定义的NewPost函数去提交内容，正确返回1到var RetVa中~

wangchao6656 · 发表于 2010-5-25 11:43:28

339是第一个web_custom_request的日志，发送的内容主要是 "Body={\"content\":\"<DIV>TEST1</DIV>\"}"，是不是参数在web_custom_request传的不对啊~
