需要注意的一点是，post请求在进行post调用时采用表单数据。

请参阅下面代码中的注释，其中也包括错误

在邮递员请求中，您的邮件正文的
requests
属性是一个数组

{
  "requests": [{...}]
}
而在你的C代码中，它是一个对象

var load = new { 
  Requests = new { ... } 
}
因此，服务器可能无法从您的请求中获取所需的数据。将
请求
属性创建为
列表
或
对象[]
，以便将其序列化为数组

var load = new {
  Requests = new List<object>{new {...}}
}

var负载=新{
请求=新列表{new{…}
}
我认为您应该更改这行代码

var load = new { Requests = new { IndexName = "magento2_tcg_productiondefault_products", Params = $"query={query}&hitsPerPage=12&maxValuesPerFacet=8&page=0&highlightPreTag=__ais-highlight__&highlightPostTag=__%2Fais-highlight__&ruleContexts=%5B%22magento_filters%22%2C%22%22%5D&facets=%5B%22mtg_setcode%22%2C%22is_foil%22%2C%22mtg_rarity%22%2C%22sf_colours%22%2C%22sf_types%22%2C%22sf_legalities%22%2C%22price.AUD.default%22%2C%22stock_qty%22%2C%22mtg_cmc%22%5D&numericFilters=%5B%22visibility_search%3D1%22%5D" } };
为此：

var load = new { Requests = new[] {new  { IndexName = "magento2_tcg_productiondefault_products", Params = $"query={query}&hitsPerPage=12&maxValuesPerFacet=8&page=0&highlightPreTag=__ais-highlight__&highlightPostTag=__%2Fais-highlight__&ruleContexts=%5B%22magento_filters%22%2C%22%22%5D&facets=%5B%22mtg_setcode%22%2C%22is_foil%22%2C%22mtg_rarity%22%2C%22sf_colours%22%2C%22sf_types%22%2C%22sf_legalities%22%2C%22price.AUD.default%22%2C%22stock_qty%22%2C%22mtg_cmc%22%5D&numericFilters=%5B%22visibility_search%3D1%22%5D" }} };

httpclient
代码在哪里？而
标题的设置在哪里？我已经添加了httpclient代码。我不太确定你所说的标题设置（这有点新）是什么意思。对于那些试图帮助你的人来说，“不起作用”也不是很好的描述。目前的回答是什么？你有例外吗？你得到一个空的答复？我认为这个错误是由URI的格式造成的。您可能需要使用
HttpUtility.UrlEncode（）
来更好地格式化您的URI。是否有错误？很抱歉，回复太晚，这很有帮助！谢谢你的解释，这很有帮助！
