对获取数据作个小结：

1、清除缓存cookie历史记录后用fiddler抓包。

2、搜索所需数据，找到数据真实网页（别忘了对fiddler事先进行设置，否则有可能搜不到

数据）

3、用代码模拟Request框的Raw按钮下的内容：

首先只写Open和Send，看是否有数据；（xmlhttp）（winhttp有时解析utf-8字符不成

功，所以初始测试首选xmlhttp）

无数据的话，首选模拟Referer；（winhttp）

仍然不行的话，观察Cookie或是URL或SendData中有无动态参数。有的话需要追根朔

源。（这步需要时间和耐心）

其他模拟一般都是小概率事件，如果遇到了我只能说你很不幸。

最后，祝你成功！

有坛友问ResponseBody和ResponseText的区别，这里补充说下：

1、ResponseBody是二进制的数据，是服务器传来的没有经过任何加工的数据。在网络中，

文本一般都是以utf-8编码，所以xmlhttp/winhttp对象的ResponseText是按照utf-8编码

把ResponseBody转换而成，也就是：ResponseText=ByteToStr(ResponseBody,"UTF-8")

至于问“为什么ByteToStr(ResponseText,"GB2312")没有结果”，原因是：一是参数类型不对，

ByteToStr的第一参数是二进制数据的Byte数组类型，ResponseText是文本类型，系统提

示出错；二是，即使进行了将文本转成二进制数据的转换（如下面代码里的b7=s这样的转

换），这种转换也是按照某种编码进行的，这样的二进制已经进行过一次编码加工了，你再

用ByteToStr就得不到原来的字符了。

处理数据的通用方法：

1、数组法：

用split和数组，循环将所需数据取出。

优点：不需其他对象辅助，起点低，会数组即可。

缺点：需要分析数据结构，对于复杂结构的数据，需要多步才能完成。

Sub Main()

Dim strText As String

Dim arrRow, arrCell

Dim i As Long, j As Long, n As Long

Dim arrColumn

Dim arrData(1 To 1000, 1 To 10)

With CreateObject("P")

.Open "GET", "/lccp/", False

.Send

strText = .responsetext

End With

arrColumn = Array(, , 9, 12, 14, 16, 18, 20, 22, 24, 26)

arrRow = Split(strText, "name='proTest' ")

For i = 1 To UBound(arrRow)

arrCell = Split(arrRow(i), ">")

n = n + 1

arrData(n, 1) = Split(Split(arrCell(0), "value='")(1), "'")(0)

For j = 2 To 10

arrData(n, j) = Split(arrCell(arrColumn(j)), "<")(0)

Next

Next

Range("a1:j1").Value = Split("产品名称 是否在售 银行 起售日 停售日 币种 管

理期(月) 产品类型 预期收益(%) 收益类型", " ")

Range("a2").Resize(n, 10).Value = arrData

End Sub

2、正则法：

用正则拆解字符串，提取匹配数据，循环取出。

优点：即便复杂结构的数据，也有可能一步到位。

缺点：需要学习正则知识。

Sub Main()

Const gc As String = "" '群号

Const bkn As String = "" '从fiddler中获取

Const uin As String = "" 'QQ号

Const skey As String = "" '从fiddler中获取

Dim strText As String

Dim RegMatch As Object

Dim arrData(1 To 1000, 1 To 2)

Dim n As Long

With CreateObject("pRequest.5.1")

.Open "GET", "/cgi-

bin/qun_info/get_group_members_new?gc=" & gc & "&bkn=" & bkn, False

.setRequestHeader "Cookie", "uin=o" & uin & "; skey=" & skey

.Send

strText = .responsetext

strText

End With

With CreateObject("")

.Global = True

.Pattern = "{""b"":d+,""g"":d+,""n"":""([^""]*)"",""u"":(d+)}"

For Each RegMatch In .Execute(strText)

n = n + 1

arrData(n, 1) = ches(0)

arrData(n, 2) = ches(1)

Next

End With

Set RegMatch = Nothing

Range("a1:b1").Value = Array("昵称", "QQ号")

Range("a2").Resize(n, 2).Value = arrData

End Sub

处理table

table数据处理，除了之前的两种通用方法外，还有以下几种方法：

1、html法

将table数据写入htmldocument对象，然后循环取出表格的各个元素。

优点：可以利用htmldocument对象整理表格。

缺点：需要学习html相关知识。

以17楼作业二为例：

Sub Main()

Dim strText As String

Dim arrData(1 To 1000, 1 To 3)

Dim i As Long, j As Long

Dim TR As Object, TD As Object

With CreateObject("P")

.Open "POST",

"/Template//Present3DList", False

.setRequestHeader "Content-Type", "application/json"

.Send "{pageindex:'1',lottory:'TC7XCData_jiangS',pl3:'',name:'江苏七星

彩',isgp: '0'}"

strText = Split(JSEval(.responsetext), "

会提示错误，所以去除这部分script代码

End With

With CreateObject("htmlfile")

.write strText

i = 0

For Each TR In .("table")(2).Rows

i = i + 1

j = 0

For Each TD In

j = j + 1

arrData(i, j) = ext

Next

Next

End With

Set TR = Nothing

Set TD = Nothing

Range("C:C").NumberFormat = "@" '设置文本格式以显示数字前面的0

Range("a1").Resize(i, 3).Value = arrData

End Sub

Function JSEval(s As String) As String

With CreateObject("Control")

.Language = "javascript"

JSEval = .Eval(s)

End With

End Function

2、QueryTable法：

这个是excel自带的网抓利器。个人觉得它最大的优势就是处理table很方便。

优点：处理table方便，代码简短。

缺点：会产生定义名称。多页循环时每页都会产生行字段名称，需要后续处理删除。

Sub Main()

With

("url;/lccp/",

Range("a1"))

.WebFormatting = xlWebFormattingNone '不包含格式

.WebSelectionType = xlSpecifiedTables '指定table模式

.WebTables = "2" '第2张table

.Refresh False

End With

End Sub

3、复制粘贴法：

table部分的文字可以直接复制到单元格内，且保留数据原格式。

优点：只需取出table部分，不需分析数据内部结构。代码编写简便。

缺点：有时格式反而是累赘。

Sub Main()

Dim strText As String

With CreateObject("P")

.Open "GET", "/lccp/", False

.Send

strText = .responsetext

End With

strText = "")(0) &

""

CopyToClipbox strText

Range("a1").Select

End Sub

Sub CopyToClipbox(strText As String)

'文本拷贝到剪贴板

With CreateObject("new:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")

.SetText strText

.PutInClipboard

End With

End Sub

处理xml数据

Sub Main()

ort _

URL:="/fzjy/tjsj/pztj/pzrtj/2014/", _

ImportMap:=Nothing, _

Overwrite:=True, _

Destination:=("a1")

End Sub

Sub Main()

Dim arrEM(1 To 4), arrEMname

Dim arrData(1000, 1 To 4)

Dim i As Long, j As Long

With CreateObject("P")

.Open "GET",

"/fzjy/tjsj/pztj/pzrtj/2014/", False

.send

arrEMname = Array(, "productid", "tradingday", "volume", "openinterest")

With .responseXML

For i = 1 To 4

Set arrEM(i) = .getElementsByTagName(arrEMname(i))

Next

For i = 0 To arrEM(1).Length - 1

For j = 1 To 4

arrData(i, j) = arrEM(j)(i).Text

Next

Next

End With

End With

Range("a1:d1").Value = Array("品种", "日期", "总成交量", "总持仓量")

Range("a2").Resize(i, 4).Value = arrData

End Sub

初识JSON

JSON数据的特点：

1、用方括号扩住的是数组，数组内元素以逗号分隔。如：["甲","乙","丙"]、[1,2,3]

2、用花括号扩住的是对象，对象内各属性以逗号分隔，属性名和属性值以冒号分隔。同一

对象里的属性名不会重复。如对象{"name":"甲","age":36}，含name、age两个属性，属性

值分别为 “甲”和36。

3、对象的属性值可以是数组。数组的元素可以是对象。JSON数据就是数组对象嵌套的大集

合。比如，下面的JSON数据记录了甲乙二人的基本信息：

JSON转换成vba对象

1、JSON数组在vba内需要用For Each来获取其元素：（For Each 后面的变量不能定义为

Object类型）

1、 JSON数组在vba内需要用For Each来获取其元素：（For Each 后面的变量不能定义为

Object类型）

Sub Test()

Const strJSON As String = "[""甲"",""乙"",""丙""]"

Dim objJSON As Object

Dim Cell '这里不能定义为object类型

With CreateObject("control")

.Language = "JavaScript"

.AddCode "var mydata =" & strJSON

Set objJSON = .CodeObject

End With

Stop '查看vba本地窗口里objJSON对象以了解JSON数据在vba里的形态

For Each Cell In

Cell

Next

End Sub

2、 JSON对象在vba内可直接用“对象.属性”的方法获取，但当名称不被vba允许时，用

CallByName函数获取：

Sub Test()

Const strJSON As String = "{""name"":""甲"",""age"":36}"

Dim objJSON As Object

With CreateObject("control")

.Language = "JavaScript"

.AddCode "var mydata=" & strJSON

Set objJSON = .CodeObject

End With

Stop '查看本地窗口

'此句出错

End Sub

登陆:

Sub Main()

Const username As String = "vbatest"

Const password As String = "12341234"

Dim strText As String

Dim uid As String

uid = username & "@"

With CreateObject("P")

.Open "POST",

"/entry/cgi/ntesdoor?df=mail163_letter&funcid=loginone&ifra

me=1&passtype=1&product=mail163&race=63_31_31_gz&uid=" & username & "@",

False

.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"

.Send

"savelogin=0&url2=http%3A%2F%%2Ferrorpage%&username

=" & username & "&password=" & password & "&password="

strText = .getallresponseheaders

strText

strText = .responsetext

strText

End With

End Sub

登录之后可以做什么----查询数据

登录并非是我们的最终目的。最终目的是查询一些非登录不能查看的数据，或是发送数据。

如论坛登录后，可下载附件，可发帖；邮箱登录后，可收件发件。

前面讲过，xmlhttp和winhttp只要该对象不销毁，都可以保持cookie。我们登录就是为了

取得一个被允许查看数据和发送数据的cookie，然后执行查询和发送的请求。

仍以网易邮箱为例：

登录后网页显示邮件列表，此过程抓包。

Sub Main()

Const Username As String = "vbatest"

Const Password As String = "12341234"

ConstAccountAsString="***************"

ConstToAccountAsString="***************"

Const Subject As String = "主题：用web发送邮件"

Const Content As String = "正文：看到此邮件则证明发送成功"

Dim strText As String

Dim Sid As String

Dim Senddata

With CreateObject("P")

.Open "POST",

"/entry/cgi/ntesdoor?df=mail163_letter&funcid=loginone&ifra

me=1&passtype=1&product=mail163&race=63_31_31_gz&uid=" & Username & "@",

False

.setrequestheader "Content-Type", "application/x-www-form-urlencoded"

.Send "username=" & Username & "&password=" & Password

Sid = Split(Split(.responsetext, "sid=")(1), "&")(0)

.Open "POST", "/js6/s?sid=" & Sid &

"&func=mbox:compose&FrameMasterMailPopupClose=1&cl_send=2&l=compose&action=deli

ver", False

.setrequestheader "Content-Type", "application/x-www-form-urlencoded"

.setrequestheader "Accept", "text/javascript" '不加这句的话返回的不是

json是xml数据

Senddata = "var=" & encodeURI("" _

& "")

.Send Senddata

.responsetext

End With

End Sub

Function encodeURI(strTobecoded As String) As String

With CreateObject("control")

.Language = "JavaScript"

encodeURI = .eval("encodeURIComponent('" & strTobecoded & "');")

End With

End Function

Function GetLongTime()

With CreateObject("control")

.Language = "JavaScript"

GetLongTime = .eval("new Date().getTime();")

End With

End Function
