vue前端
this.$http
.post("http://192.168.1.102/api/WeatherForecast/Set", { Id: 123 ,name:"qqq"})
.then(res => {
console.log(res);
});
}
后端：
方案1：（代码较多，不喜欢）
[HttpPost]
public async Task<string> Set()
{
Stream stream = Request.Body;
if (stream != null)
{
using (var reader = new StreamReader(stream, Encoding.UTF8))
{
string dataStr = await reader.ReadToEndAsync();
var paramsObj = new { Id = 0, name = "" };
paramsObj = JsonConvert.DeserializeAnonymousType(dataStr, paramsObj);
}
}
return "ok";
}
方案2：
[HttpPost]
public string Set([FromBody] dynamic formData)
{
var aa= formData;
string dataStr= formData.ToString();
var paramsObj = new { Id = 0, name = "" };
paramsObj = JsonConvert.DeserializeAnonymousType(dataStr, paramsObj);
return "ok";
}
