【已解决】请问各位大神，如何模拟HTTP multipart/form-data 上传图片呢？
本帖最后由 zghwelcome 于 2018-4-3 13:46 编辑折腾了一天，看了 multipart/form-data 表单的定义，服务器总数返回“数据请求失败”，抓包对比了不知道问题究竟出在哪，跪了。求大神支招！
谢谢 alaws 大佬指点，错误就是 二进制和字符串夹杂传输导致的。下面都改用二进制传输正常了！再次表示感谢！
解决的代码：$str = _UpFile(@ScriptDir & '\jzpz.jpg')
MsgBox(0,0,$str)
Func _UpFile($sJpgFile)
Local $boundary = '----WebKitFormBoundaryAYqnZ87PoiVPmW05' ;//分隔字符串
;//读取图片文件
$open = FileOpen($sJpgFile, 16)
Local $sReadJpg = FileRead($open)
FileClose($open)
;//构建图片数据包
Local $sPostData =StringToBinary($boundary & @CRLF & _ ;//分界线
'Content-Disposition: form-data; name="upFile"; filename="jzpz.jpg"' & @CRLF & _
'Content-Type: image/jpeg' & @CRLF & @CRLF ,1)& _
$sReadJpg & StringToBinary( $boundary & @CRLF & _
'Content-Disposition: form-data; name="file_id"' & @CRLF & @CRLF & _
'0' & @CRLF & _
$boundary & '--' ,1)
Local $oHTTP = ObjCreate("Microsoft.XMLHTTP")
$oHTTP.Open('POST', 'http://*******/sysEntFile/BootstrapUploadFile.jhtml?moduleType=trouble&investigationType=1&url=/investigationImage/saveBootstrapInvestigationImage.jhtml&investigationId=0&imageType=1', True) ;// 异步
$oHTTP.setRequestHeader("Host", '******')
$oHTTP.setRequestHeader("Pragma", "no-cache")
$oHTTP.setRequestHeader("Connection", "keep-alive")
$oHTTP.setRequestHeader("Accept", "application/json, text/javascript, */*; q=0.01")
$oHTTP.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko")
$oHTTP.setRequestHeader("Referer", 'http://******/investigationAccount/uploadImage.jhtml?investigationId=0&imageType=1&investigationType=1')
$oHTTP.setRequestHeader("Accept-Language", "zh-CN,zh;q=0.9")
$oHTTP.setRequestHeader("X-Requested-With", "XMLHttpRequest")
$oHTTP.setRequestHeader("Content-Type", "multipart/form-data; boundary=" & $boundary)
$oHTTP.setRequestHeader("Origin", "http://*****")
$oHTTP.Send($sPostData)
While 1
Sleep(50)
$readystate = $oHTTP.readystate
If $readystate = 4 Then ExitLoop
WEnd
$Content = $oHTTP.responseBody
$header = $oHTTP.getAllresponseheaders
$oHTTP.abort()
$oHTTP = 0
Return$header & @CRLF & @CRLF & BinaryToString($Content, 4)

测试页面：http://******/investigationAccount/uploadImage.jhtml?investigationId=0&imageType=1&investigationType=1 表面上看POST数据包那里的数据格式不正确，从你构造的内容来看，在最终使用send方法发送数据是“字符串(其中混有二进制数据，也是字符串)”，你按下面的方法修改试试（让使用send方法时发送的是纯二进制数据）
你原来的格式：$sPostData=字符串 + 图片二进制 + 字符串
请尝试修改为：$sPostData=StringToBinary(字符串) + 图片二进制 + StringToBinary(字符串)
另外，请不要试图：sPostData=StringToBinary(字符串 + 图片二进制 + 字符串) 回复 4# alaws
谢谢大神指点，一定要给你365个赞！ {:face (356):}
