.net core webapi 返回 html(非视图)

.net core webapi 返回 html(非视图)

近期遇到很多提示的问题,所以很多时候,需要后端返回html到前端作为提示。那么很多时候,可以在后端控制,就要用到这种方法:

使用dotnet core webpi的时候,如何返回html格式到前端。

使用语言:C#
当前环境:.Net Core 2.2.6(SDK)version:2.2.401
废话不多说,直接上代码(最后的代码块就是我们的完整代码)
核心代码:

public async Task ReturnHtml()
{
    StringBuilder htmlStringBuilder = new StringBuilder();
    var data = Encoding.UTF8.GetBytes("返回的内容");
    if (accept.Any(x => x.MediaType == "text/html"))
    {
        Response.ContentType = "text/html";
    }
    else
    {
        Response.ContentType = "text/plain";
    }
    await Response.Body.WriteAsync(data, 0, data.Length);
}

完整代码:

/// <summary>
///     返回html的组合
/// </summary>
/// <returns></returns>
[HttpGet]
[Route("api/Message/ReturnHtml")]
public async Task ReturnHtml()
{
    StringBuilder htmlStringBuilder = new StringBuilder();
    htmlStringBuilder.Append("<html>");
    htmlStringBuilder.Append("<head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /> </head>");//支持中文
    htmlStringBuilder.Append("<body>");
    htmlStringBuilder.Append("<spen style=\"font-size: 300%\">");//让字体变大
    string a = $"返回的内容";
    htmlStringBuilder.Append(a);
    htmlStringBuilder.Append("</spen>");
    htmlStringBuilder.Append("</body>");
    htmlStringBuilder.Append("</html>");
    result = htmlStringBuilder.ToString();
    var data = Encoding.UTF8.GetBytes(result);
    if (accept.Any(x => x.MediaType == "text/html"))
    {
        Response.ContentType = "text/html";
    }
    else
    {
        Response.ContentType = "text/plain";
    }
    await Response.Body.WriteAsync(data, 0, data.Length);
}
