json - Invoke-RestMethod - POST 响应格式不是 JSON？

问题描述

如果我使用 PUT、DELETE 或 GET 等方法，我没有任何问题。 $wresponse是正常的 JSON 响应。

当我尝试使用 POST 时，我得到的响应看起来像 HTML。

执行代码：

$wresponse = Invoke-RestMethod -Uri https://**************/wp-json/wc/v3/products/ -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)} -Body $body -ContentType "application/json" -Method post

执行产品通常添加到数据库后，但响应如下所示（del 标记后的 JSON？）：

    <title>Document Moved</title>

<body>
    <h1>Object Moved</h1>This document may be found
    <a HREF="https://*************/wp-json/wc/v3/products/1507">here</a>

问题可能出在哪里？或者这是正常的，我应该以某种方式从这个响应中提取 JSON？

解决方案

这称为POST/REDIRECT/GET。网站这样做是为了防止从网络浏览器重复提交。这是一个服务器端实现问题，而不是您的 PowerShell 问题（除非 API 文档提到此重定向，在这种情况下，您需要让 PowerShell 处理重定向并遵循它）。
