Question

如果我使用PUT，DELETE或GET之类的方法，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

通常将执行后产品添加到数据库中，但响应如下所示（del标签后为JSON？）：

    <head>
    <title>Document Moved</title>
</head>
<body>
    <h1>Object Moved</h1>This document may be found
    <a HREF="https://*************/wp-json/wc/v3/products/1507">here</a>
</body> {"id":1507,"name":"test article","slug":"test-article","permalink":"https:\/\/************\/izdelek\/testni-artikel\/","date_created":"2019-01-29T11:29:15","date_created_gmt":"2019-01-29T10:29:15","date_modified":"2019-01-29T11:29:15","date_modified_gmt":"2019-01-29T10:29:15","type":"simple","status":"publish","featured":false,"catalog_visibility":"visible","description":"bla bla bla","short_description":"bla bla bla","sku":"","price":"10","regular_price":"20","sale_price":"10","date_on_sale_from":null,"date_on_sale_from_gmt":null,"date_on_sale_to":null,"date_on_sale_to_gmt":null,"price_html":"

问题可能出在哪里？还是这很正常，我应该以某种方式从此响应中提取JSON？

Answer 1

这称为POST/REDIRECT/GET。网站这样做是为了防止来自Web浏览器的重复提交。这是服务器端的实现问题，而不是PowerShell的问题（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）。

Answer 2

您有权访问运行此API的后端代码吗？我认为那是您需要看的地方。

在我看来就像302 Object Moved响应。您首先获得HTML，然后在末尾附加JSON响应。

请注意，包含标记的HTML实际上是一个json转义的字符串文字值，它是“ price_html”的值。这就是为什么所有双引号都被转义的原因。

无论如何都在后端代码中寻找问题，由于某种原因，它首先返回HTML代码，然后返回您（可能是预期的）JSON响应的组合。

Invoke-RestMethod-POST响应格式不是JSON吗？
