发布API错误的Invoke-RestMethod

Question

为此，我尝试使用powershell的kanboard API (kanboard.org)，本质上是使用curl，这正是Invoke-RestMethod的用法。

我得到了下面的错误；

Invoke-RestMethod : Cannot bind parameter 'Headers'. Cannot convert the ""X-API-Auth",
"agBzAG8AbgByAHAAYwA6ADQAMgBjAGQANwAwADEAMgA3ADgAMgAyAGMAYwBiAGUANwA1ADcAMAA3AGYANQBmAGUAZQA2ADkANgBmADYAYQA1AGIAOQAwADIANABiADEAZQBhADAANwBjAGIAOQA1ADQAYQA5AGQAYQA5AGMAYQAwAGYAYgA0AA=="" value of type
"System.String" to type "System.Collections.IDictionary".
At line:1 char:77
+ ... RestMethod -Uri $kanboardserver -Method Post -Headers $header -Body $ ...
+                                                           ~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Invoke-RestMethod], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

我使用powershell的API调用代码如下；

$kanboardserver = "http://mykanboardserver/jsonrpc.php"
$kanboardtoken = "jsonrpc:42cd70127822ccbe75707f5fee696f6a5b9024b1ea07cb954a9da9ca0fb4"
$converted = $kanboardtoken | ConvertTo-Base64

$headersKan = New-Object "System.Collections.Generic.Dictionary[[String],[String]]" -ErrorAction Stop
$headersKan.Add("X-API-Auth", $converted)

$payload = @{ jsonrpc = "2.0"; 
            method = "getAllProjects"; 
            id = 1;
            } | ConvertTo-Json

$responseKan = Invoke-RestMethod -Uri $kanboardserver -Method Post -Headers $header -Body $payload -ErrorAction Stop
Write-Host $responseKan

仅供参考，这是如何使用CURL调用API的文档示例，这也是我上面代码的基础。(https://docs.kanboard.org/en/latest/api/examples.html)

curl \
-u "jsonrpc:19ffd9709d03ce50675c3a43d1c49c1ac207f4bc45f06c5b2701fbdf8929" \
-d '{"jsonrpc": "2.0", "method": "getAllProjects", "id": 1}' \
http://localhost/kanboard/jsonrpc.php

您应该为headers IDictionary参数使用哈希表，如下所示：

关于你的base64字符串，我不知道你使用的ConvertTo-Base64，不管怎样，我是这样做的：

$kanboardtoken = "jsonrpc:57c9d99c1f5629959d237822a000a20b22913c71688e6520e5638beec11b"
$Base64 = [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($kanboardtoken))


$headers = @{
'X-API-Auth' = $Base64
}

$payload = @{ jsonrpc = "2.0"; 
            method = "getAllProjects"; 
            id = 1;
            } | ConvertTo-Json

$responseKan = Invoke-RestMethod -Uri $kanboardserver -Method Post -Headers $headers -Body $payload -ErrorAction Stop

Answer 2

谢谢，所以我又回到了以前遇到的一个错误，这是一个授权问题。

Invoke-RestMethod : {"jsonrpc":"2.0","error":{"code":401,"message":"Unauthorized"},"id":null}

我知道令牌是正确的，因为我已经模拟了一个php客户端，并且API正在工作。

给我这个错误的最新代码如下，它必须与头部的形成方式有关，我想不出其他任何东西。

 $kanboardserver = "http://mykanboardserver/jsonrpc.php"
    $kanboardtoken = "jsonrpc:57c9d99c1f5629959d237822a000a20b22913c71688e6520e5638beec11b" | ConvertTo-Base64

    $headers = @{
        'X-API-Auth' = $kanboardtoken
        }

    $payload = @{ jsonrpc = "2.0"; 
                method = "getAllProjects"; 
                id = 1;
                } | ConvertTo-Json


        $responseKan = Invoke-RestMethod -Uri $kanboardserver -Method Post -Headers $headers -Body $payload -ErrorAction Stop
        Write-Host $responseKan
