1、接口说明

通过互联网访问，接口调用为HTTP请求的方式，每一次由用户发起的HTTP请求，需要设置验证信息，具体方法是，在HTTP Header部分增加version及authenticate属性，属性值在联调测试之前由总部提供。

接口调用地址：http:// IP:Port/invoke/path/{mail_num}

接口调用方式：HTTP GET方式，通过HTTP GET发起请求，使用真实邮件号替换{mail_num}

编码格式：UTF-8

接口返回数据格式：

{"traces":[{"acceptTime":"2011-11-2417:55:00","acceptAddress":"上海邮政速递物流长宁经营部","remark":"收寄"},{"acceptTime":"2011-11-2417:59:00","acceptAddress":"上海邮政速递物流长宁经营部","remark":"离开处理中心,发往上海市邮政公司邮政速递局"},{"acceptTime":"2011-11-2423:54:38","acceptAddress":"上海市","remark":"到达处理中心,来自上海邮政速递物流长宁经营部"},{"acceptTime":"2011-11-2500:17:42","acceptAddress":"上海市","remark":"离开处理中心,发往USSFOF"},{"acceptTime":"2011-12-0507:41:00","acceptAddress":"美国 94704","remark":"到达投递局"},{"acceptTime":"2011-12-0511:07:00","acceptAddress":"美国94703","remark":"妥投"}]}

acceptTime表示处理时间

acceptAddress表示处理地点

remark表示处理动作

2、查询界面

3、查询结果

4、程序实现

<pre name="code" class="vb">Dim tt, stime(80), saddr(80), state(80) As String

Public Sub get_data()
    '
    Dim HttpReq As Object
    Dim i, k, kk, row1 As Integer

    'lineno = ActiveSheet.UsedRange.Rows.Count
    Set HttpReq = CreateObject("MSXML2.XMLHTTP.3.0")
    
    row1 = 2
    maxrow = Sheets("查询结果").UsedRange.Rows.Count
    If maxrow >= 2 Then
        Sheets("查询结果").Range("A2:D" & maxrow).ClearContents
    End If
    For i = 2 To lineno
        mail = Cells(i, 1)

        HttpReq.send
        'MsgBox HttpReq.getAllResponseHeaders
        'MsgBox HttpReq.responseText
        
        kk = get_trace(HttpReq.responseText)
        Cells(i, 2) = tt
        Sheets("查询结果").Cells(row1, 1) = mail
        For k = 1 To kk
            Sheets("查询结果").Cells(row1, 2) = stime(k)
            Sheets("查询结果").Cells(row1, 3) = saddr(k)
            Sheets("查询结果").Cells(row1, 4) = state(k)
            row1 = row1 + 1
        Next k
        If CInt((lineno - i) / 10) * 10 = lineno - i Then
            Application.StatusBar = "剩余邮件数：" & lineno - i
        End If
    
    Next i
    
    Sheets("查询结果").Activate
    msg = MsgBox("邮件批量查询完毕，共查询" & i - 3 & "个邮件！", vbOKOnly, "ＡＨＥＭＳ：iamlaosong")
