WebAPI 参数问题

POST:

  1.  public HttpResponseMessage PostTest()

   2. public HttpResponseMessage PostTest(string parame)

   3.public HttpResponseMessage PostTest(object parame)

第一种无参数的请求很简单 正常调用即可

第二种有明确参数类型的请求 尼玛试了一下午都不知道怎么请求

第三种object类型的请求 可以正常调用 但是请求的类型需要指定规范不然传递过去的得到的值是null,建议设置为json传递(ContentType= application/json)

GET:

   1.public HttpResponseMessage GetTest()

   2.public HttpResponseMessage GetTest(string parame)

第一种无参数的请求很简单 正常调用即可

第二种有明确参数类型的请求 直接在URL上加上对应名称的即可 如   xxxxx?parame=123

c# HttpWebRequest类ContentType值类型列表

  1. text/html : HTML格式
  2.  text/plain :纯文本格式
  3.  text/xml : XML格式
  4.  image/gif :gif图片格式
  5.  image/jpeg :jpg图片格式
  6.  image/png:png图片格式

     以application开头的媒体格式类型:

       application/xhtml+xml :XHTML格式
      application/xml : XML数据格式
      application/atom+xml :Atom XML聚合格式
      application/json : JSON数据格式
      application/pdf :pdf格式
      application/msword : Word文档格式
      application/octet-stream : 二进制流数据(如常见的文件下载)
      application/x-www-form-urlencoded : <form encType=””>中默认的encType,form表单数据被编码为key/value格式发送到服务器(表单默认的提交数据的格式)

 

 

 

  C#简单请求

            return null;

            }
