[英]Returning JSON in ASP.NET controller method
我有以下工作控制器方法,該方法以簡單文本格式返回JSON。
[HttpPost]
public IActionResult DecodeBarcode(string productCodeScheme, string productCode, string serialNumber, string batch, string expirationDate, int commandStatusCode) {
string TextAreaResult = string.Empty;
try {
TextAreaResult = string.Format("{0} {1} {2}", request.getHttpInformation(), request.getHttpWarning(), request.getHttpResponseCode());
} catch (Exception exc) {
TextAreaResult = "Exception: " + exc.Message;
}
return Json(TextAreaResult);
}
運行上述方法后的輸出看起來像
"The pack is active No warning 200"
而
request.getHttpInformation() is The pack is active
request.getHttpWarning() is No warning
request.getHttpResponseCode() is 200
現在,我嘗試將響應分為3個不同的鍵值對,以便我的響應看起來像
{
httpInformation: "The pack is active",
httpWarning: "No Warning",
httpResponseCode: "200"
}
如何在return Json(TextAreaResult)
調用中傳遞其他參數?
如果我喜歡以下內容,它將無法正常工作
[HttpPost]
public IActionResult DecodeBarcode(string productCodeScheme, string productCode, string serialNumber, string batch, string expirationDate, int commandStatusCode) {
string TextAreaResult = string.Empty;
string TextAreaResultHttpInformation = string.Empty;
string TextAreaResultHttpWarning = string.Empty;
string TextAreaResultHttpResponseCode = string.Empty;
try {
TextAreaResultHttpInformation = string.Format("{0}}", request.getHttpInformation());
TextAreaResultHttpWarning = string.Format("{1}}", request.getHttpWarning());
TextAreaResultHttpResponseCode = string.Format("{2}}", request.getHttpResponseCode());
} catch (Exception exc) {
TextAreaResult = "Exception: " + exc.Message;
}
return Json(TextAreaResultHttpInformation, TextAreaResultHttpInformation, TextAreaResultHttpResponseCode);
}
如何構造鍵值對並以JSON形式返回? 也許, Json
方法不是這里的正確選擇,但是對於C#來說是新手,我不知道其他任何C#內置方法來構造JSON
假設您實際上想將響應作為JSON使用,則可以通過執行以下操作來實現
return Json(new
{
HttpInformation = TextAreaResultHttpInformation,
HttpWarning = TextAreaResultHttpWarning,
StatusCode = TextAreaResultHttpResponseCode
});
您可以為這些屬性創建包裝器類並返回它。
public class BarcodeResultDto
{
[JsonProperty("httpInformation")]
public string HttpInformation { get; set; }
[JsonProperty("httpWarning")]
public string HttpWarning { get; set; }
[JsonProperty("httpResponseCode")]
public int GetHttpResponseCode { get; set; }
}
public IActionResult DecodeBarcode(string productCodeScheme, string productCode, string serialNumber,
string batch, string expirationDate, int commandStatusCode)
{
var barcodeResult = new BarcodeResultDto
{
GetHttpResponseCode = 200,
HttpInformation = "The pack is active",
HttpWarning = "No Warning"
};
// your code here
return Ok(barcodeResult);
}
或者,您可以將重新調整后的值從IActionResult更改為JsonResult
如果您想使用其他方法,則可以通過以下方式使用JsonSerializer:
// Creating BlogSites object
BlogSites bsObj = new BlogSites()
{
Name = "test-name",
Description = "test-description"
};
// Serializing object to json data
JavaScriptSerializer js = new JavaScriptSerializer();
string jsonData = js.Serialize(bsObj); // {"Name":"test-name","Description":"test-description"}
您只需要創建一個類並將值存儲在其對象中,然后對其進行序列化即可。 如果有列表,則可以使用該類的列表,然后進行序列化。
