ASP.NET Core中WordPressPCL 2.0.1的Post.CreateAsync调用失败求助

问题代码 #

var client = new WordPressClient( "http://sitioweb.com/wp-json/" );
client.Auth.UseBasicAuth( "username", "app_password" );
        
var post = new Post() {
  Title = new Title( "ITCmx" ),
  Content = new Content( "Content PostCreate" )
};

var createdPost = await client.Posts.CreateAsync( post );

错误信息 #

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type
'WordPressPCL.Models.Post' because the type requires a JSON object
(e.g. {"name":"value"}) to deserialize correctly. To fix this error
either change the JSON to a JSON object (e.g. {"name":"value"}) or
change the deserialized type to an array or a type that implements a
collection interface (e.g. ICollection, IList) like List that can be
deserialized from a JSON array. JsonArrayAttribute can also be added
to the type to force it to deserialize from a JSON array. Path '',
line 1, position 1.

解决方案 #

1. 修正WordPress API端点路径 #

WordPress REST API的文章操作端点默认在/wp/v2/posts，初始化WordPressClient时需包含完整基础路径，否则库可能请求错误端点（返回文章列表数组而非创建后的单个文章对象）。修改初始化代码：

var client = new WordPressClient( "http://sitioweb.com/wp-json/wp/v2/" );

2. 为Post对象添加必填状态字段 #

WordPress创建文章时需指定状态（默认可能未正确设置），添加Status属性确保API返回正确的单个文章对象：

var post = new Post() {
  Title = new Title( "ITCmx" ),
  Content = new Content( "Content PostCreate" ),
  Status = "publish" // 或 "draft"，根据需求选择
};

3. 验证请求的实际端点与响应 #

通过调试工具（如Fiddler）或添加日志，确认CreateAsync调用的实际URL是否为http://sitioweb.com/wp-json/wp/v2/posts，并查看API返回的响应内容。若返回仍为数组，说明端点路径仍有问题，需检查WordPress站点的API配置。

4. 检查WordPressPCL版本兼容性 #

WordPressPCL 2.0.1可能存在与部分WordPress版本的兼容性问题，尝试更新到较新的稳定版本，或确认站点使用的WordPress版本是否支持该库的API调用规范。
