我想设置ServiceStack的默认格式为JSON，相对于HTML格式的响应当服务从浏览器访问它正常返回。我知道这对每个请求通过发送？格式= json的参数或接受头设置为应用程序/ JSON指定。有没有办法来改变这种无需依赖这些提示的要求？

I would like to set ServiceStack's default format to JSON, as opposed to the HTML formatted response it normally returns when a service is accessed from a browser. I know this can be specified on each request by sending a ?format=json parameter or setting the Accept header to application/json. Is there a way to change this without having to rely on these hints from the request?

推荐答案

在除了与？格式= JSON 的通过附加格式 .EXT 的路线，比如年底：的 / rockstars.json ，或通过指定的HTTP标头（在你的HttpClient）：接受：应用/ JSON 。

In addition to specifying it on the QueryString with ?format=json, by appending the format .ext to the end of the route, e.g: /rockstars.json, or by specifying the HTTP Header (in your HttpClient): Accept: application/json.

否则，如果你的HttpClient不发送和接收报头，您可以指定JSON作为您的APPHOST具有默认的内容类型：

Otherwise if your HttpClient doesn't send an Accept header you can specify JSON as the default content type in your AppHost with:

SetConfig(new HostConfig {
     DefaultContentType = MimeTypes.Json 
});

在ServiceStack所有配置选项都在这里设置。

All Configuration options in ServiceStack are set here.

从Web浏览器调用Web服务时的问题是，它们通常要求接受：text / html的，而不是JSON其通过合同ServiceStack责成通过返回回来的HTML，如果它被启用。

The issue when calling web services from a web browser is that they typically ask for Accept: text/html and not JSON which by contract ServiceStack obliges by returning back HTML if it is enabled.

要确保JSON返回您可能还需要与禁用HTML功能：

To ensure JSON is returned you may also want to disable the HTML feature with:

SetConfig(new HostConfig {
    EnableFeatures = Feature.All.Remove(Feature.Html),
});

不同的方式来指定响应内容类型

否则，如果要覆盖Accept头，你可以强制服务始终返回JSON与任何一种方式来的自定义HTTP响应，例如：

使用滤波器（的AddHeader是内置的）：

Using a filter (AddHeader is built-in):

[AddHeader(ContentType=MimeTypes.Json)]
public object Any(Request request) { ... }

设置了服务的响应：

Setting the Response in the service:

public object Any(Request request) 
{ 
    base.Response.ContentType = MimeTypes.Json;
    return dto;
}

返回一个装饰的响应：

Returning a decorated response:

return new HttpResult(dto, MimeTypes.Json);
