Sge*_*dda 7 c# swagger asp.net-core
我在 swagger 中将 api 响应渲染为 xml 时遇到了一些问题,最后我用下面的第一个操作将其渲染为正确的格式 application/xml ,但它仍然说我只能将其渲染为 application/json 。
我尝试从 Produces 属性中删除 application/json,但仍然仅显示 application/json。
有什么想法为什么会这样吗?
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().AddMvcOptions(o => o.OutputFormatters.Add(new XmlDataContractSerializerOutputFormatter()));
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
c.RoutePrefix = "";
});
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info { Title = "My API", Version = "v1" });
c.AddSecurityDefinition("Bearer", new ApiKeyScheme { In = "header", Description = "Please enter JWT with Bearer into field", Name = "Authorization", Type = "apiKey" });
c.AddSecurityRequirement(new Dictionary<string, IEnumerable<string>> {
{ "Bearer", Enumerable.Empty<string>() },
});
});
}

和行动:
[Produces("application/json", "application/xml")]
public ContentResult GetByAddress(string address)
{
var addressId = GetAddressIdByAddress(address);
string result = _soapApi.GetResultById(addressId);
return Content(result, "application/xml", Encoding.UTF8);
}

与以下结果相同:
[Produces("application/json", "application/xml")]
public IActionResult GetByAddress(string address)
{
var addressId = GetAddressIdByAddress(address);
string result = _soapApi.GetResultById(addressId);
return Content(result, "application/xml", Encoding.UTF8);
}

虽然这样:
[Produces("application/json", "application/xml")]
public string GetByAddress(string address)
{
var addressId = GetAddressIdByAddress(address);
string result = _soapApi.GetResultById(addressId);
return result;

{
string result = _soapApi.GetResults();

结果是:
由于不同参数返回的数据结构不同,我无法返回已解析对象的列表。所以此时我只收到原始的soap xml 数据并且必须解析/反序列化它。但为了真正能够看到原始响应,我还需要将其显示为内容类型为 application/xml 的字符串内容。它给了我一个很好的输出,例如(尽管它仍然说只有 application/json 是可能的):
总结一下:
当字符串被解析为其实际格式时,我没有让它与显示正确内容类型的响应内容类型一起工作(在“响应内容类型”-过滤器中),如下所示。即使这会导致最重要的 application/xml 的正确输出(参见上面的屏幕截图);
[Produces("application/json", "application/xml")]
public ContentResult GetByAddress(string address)
{
return Content("<xml>...</xml>", "application/xml", Encoding.UTF8);
}

这是因为返回类型覆盖了注释。为了让它按您希望的方式工作,您需要返回 IActionResult 并使用注释来提供特定代码应采用的响应类型模型。
因此,不要返回result,而是返回Ok(result)
我创建了示例代码,它使用 swagger 4.0.1 对我有用
[HttpGet("Get2")]
[Produces("application/json", "application/xml", Type = typeof(List<string>))]
public IActionResult Get2()
{
var list = new List<string>() { "value1", "value2" };
return Ok(list);
}
