c# - 在 swagger C# .net 核心中使用 FormData 发送字符串数组？

Question

我的.net api签名如下:

[HttpPost]
public async Task<ActionResult<ServiceResult>> SendEmail([FromForm]SendEmailModel model)

下面是我的 swagger 配置:

services.AddSwaggerGen(c =>
{
    c.SwaggerDoc("v1", new Info
    {
        Version = "v1",
        Title = "App-Service"       
    });
});

.
.
.

app.UseSwagger();
app.UseSwaggerUI(c =>
{
    c.DocumentTitle = "App Service";
    c.SwaggerEndpoint("/swagger/v1/swagger.json", "App Service");
});
app.UseMvc();

它生成如下内容:

但是当我执行它时，To 参数发送为

[
  "\"1\",\"2\",\"3\""
]

但必须是:

[
  "1", "2", "3"
]

我该如何解决？

最好像Vinit Patel说的那样把contract改成[FromBody]。但是，如果这不是一个选项，您将不得不像这样对您的 SendEmailModel 模型做一些骇人听闻的事情:

[HttpPost]
public async Task<ActionResult<ServiceResult>> SendEmail([FromForm]SendEmailModel model)
{
    model.To = Regex.Replace(model.To.FirstOrDefault(), "\"", string.Empty)
            .Split(",", StringSplitOptions.None);

    //now you can loop through model.To as a string array
    foreach (string toEmail in model.To)
    {
            // Your logic here
    }
    ...
}

这可能不是最好的解决方案，但我希望它能有所帮助:)
