如何在azure http触发函数中读取JSON响应的属性?

Question

我有下面的代码和下面的Json样本在requestBody中返回。我想检查我的requestBody是否包含键ComputerModel，如果包含，我想获得那个值。我该怎么做呢?

Json响应我得到快速观察:(requestBody)

{
"id": "Test",  
"Type": "Test",
"ComputerModel": "Testings"  
"Properties": {
"Access": "CUSTOMER"
}
}

c#代码:

public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]
HttpRequest req, ILogger log)
{
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
string computermodel= req.Query["ComputerModel"]; // I don't  get anything here
string responseMessage = string.IsNullOrEmpty(Computermodel) 
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello, {name}. This HTTP triggered function executed successfully.";
return new OkObjectResult(responseMessage);
}

您的json似乎不像评论中讨论的那样正确。正确的Json格式如下:

{
"id": "Test", 
"Type": "Test", 
"ComputerModel": "Testings",   
"Properties": {
"Access": "CUSTOMER" 
}
}

使用上面的Json，您可以使用JObject解析它。req.Query给出查询字符串参数，但您的json被发布为post body。

var jObject = JObject.Parse(requestBody );
Console.WriteLine(jObject["ComputerModel"].ToObject<string>());
