在Powershell中发布具有相同名称的表单字段

Question

我希望使用Powershell（v4）模拟POST请求。 Fiddler使我能够在以下所有相关方面复制原文：

我尝试了很多方法，最简单的解释/演示可能是：

invoke-webrequest -Uri "$uri"  `
  -body @{
    _program='/Web/storm'
    SASControlTable='[{"Name":"COL1","Type":"str"},{"Name":"COL2","Type":"str"}]'
    SASControlTable='[{"COL1":"VAL1","COL2","VAL2"}]'
  } -method post  -usedefaultcredentials

这给出了错误：

  

哈希文字中不允许使用重复键'SASControlTable'。

如何使用Powershell提交多个具有相同名称的字段？

修改

我的实际http正文如下：

_program=%2FWeb%2Fstorm&_debug=0&_service=default&SASControlTable=%5B%7B%22colName%22%3A%22ACTION%22%2C%22colType%22%3A%22string%22%2C%22colLength%22%3A14%7D%5D&SASControlTable=%5B%7B%22ACTION%22%3A%22INITIALISATION%22%7D%5D

使用Powershell提交相同的主体并没有在fiddler的WebForms选项卡中为SASControlTable提供两个参数（并且Web服务器仅接收第二个参数）。这是我试图解决的问题..

如何使用＆＃34; here strings＆＃34;？

$body = @"
_program='/Web/storm'
SASControlTable='[{"Name":"COL1","Type":"str"},{"Name":"COL2","Type":"str"}]'
SASControlTable='[{"COL1":"VAL1","COL2","VAL2"}]'
"@

invoke-webrequest -Uri $uri -body $body -method post -usedefaultcredentials

PS 你可能需要也可能不需要双引号

PPS 最有可能上面不会工作 - 看看Fiddler＆＃34; Raw＆＃34;选项卡并在$ body

中复制请求正文

PPPS 或者您可以提出请求，获取表单/字段，填充它们并提出另一个请求。看看帮助

Get-Help Invoke-WebRequest -ShowWindow

PPPPS

此

$body = '_program=%2FWeb%2Fstorm&_debug=0&_service=default&SASControlTable=%5B%7B%22colName%22%3A%22ACTION%22%2C%22colType%22%3A%22string%22%2C%22colLength%22%3A14%7D%5D&SASControlTable=%5B%7B%22ACTION%22%3A%22INITIALISATION%22%7D%5D'

(Invoke-WebRequest https://httpbin.org/post -Method Post -Body $body).content

在Posh中

：

{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "SASControlTable": [
      "[{\"colName\":\"ACTION\",\"colType\":\"string\",\"colLength\":14}]", 
      "[{\"ACTION\":\"INITIALISATION\"}]"
    ], 
    "_debug": "0", 
    "_program": "/Web/storm", 
    "_service": "default"
  }, 
  "headers": {
    "Content-Length": "224", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "Mozilla/5.0 (Windows NT; Windows NT 10.0; en-US) WindowsPowerShell/5.1.14393.82"
  }, 
  "json": null, 
  "origin": "94.72.189.16", 
  "url": "https://httpbin.org/post"
}

和Fiddler

看起来就像你得到的那样
