StringContent-mediaType参数 [英] StringContent - mediaType Parameter

问题描述

是否有人知道'mediaType'参数对StringContent的构造函数有什么作用?在其MSDN页面上没有列出任何内容.

Does anyone have any idea what the 'mediaType' parameter does for the StringContent's constructor? Nothing is listed on its MSDN page.

谢谢.

推荐答案

哇，是创建StringContent的新实例时，它总是设置媒体类型.如果您未指定，则使用"text/plain"；否则，它将使用您传入的任何内容.(似乎对传入的值进行了一些验证，但我不太了解它的作用.)

When you create a new instance of StringContent, it always sets a media type. If you don't specify one, it uses "text/plain"; otherwise, it uses whatever you passed in. (There appears to be some validation done on the value you pass in, but I don't really understand what it's doing.)

该媒体类型值随后用于实例化一个新的MediaTypeHeaderValue，该新MediaTypeHeaderValue分配给您的StringContent的Headers.ContentType属性.

That media type value is then used to instantiate a new MediaTypeHeaderValue, which is assigned to your StringContent's Headers.ContentType property.

从文档中查找标头:

获取RFC 2616中定义的HTTP内容标头.

Gets the HTTP content headers as defined in RFC 2616.

对Content-Type属性的评论:

The comment on the Content-Type property:

HTTP响应中Content-Type内容标头的值.

The value of the Content-Type content header on an HTTP response.

所有这些，显然是在指定HTTP内容类型.

So all that to say, it's apparently specifying the HTTP content type.

这是类型的完整列表，太长，无法包含在此处.我确定MSDN上也有一个列表，但找不到.

Here's a full list of types, which is too long to include here. I'm sure there's a list somewhere on MSDN too but I couldn't find one.
