从 API (C#) 解析 JSON 数据

[英]Parsing JSON data from API (C#)

我目前正在以应用程序/json 数据的形式从 web api 获取信息。 我遇到的问题是,有时我使用 JObject.Parse(response) 时会出错,而使用 JArray.Parse(response) 时却没有,有时反之亦然。 我一直在四处寻找,但无法弄清楚为什么返回的某些数据有 [] 而有些则没有。 话虽如此,有没有办法一致地解析数据,无论它是否有 [] ? 我目前唯一能想到的是检查响应字符串是否以'['开头,如果是则使用JArray.Parse,如果不是则使用JObject.Parse,但这看起来有点难看解决方案。 一般来说,我对 API 还是很陌生,所以任何建议都将不胜感激。

(编辑:语言是 C#)

代码片段:

using (WebClient webClient = new WebClient())
{
    webClient.Headers.Add("Authorization", "Basic ***");
    webClient.Headers.Add("clientId", clientId);
    webClient.Headers.Add("Content-Type", "application/json");
    string agreementResponse = webClient.DownloadString(urlAgreementBase + urlAgreementParams);
    if (response == null)
    {
        throw new InvalidPluginExecutionException("Failed to retrieve company. Response was empty.");
    }
    var agreementObject = JArray.Parse(response);
}

JSON:

[
    {
        "id": int,
        "name": "string",
        "type": {
            "id": int,
            "name": "string",
            "_info": {
                "type_href": "url string"
            }
        },
        "company": {
            "id": int,
            "identifier": "string",
            "name": "string",
            "_info": {
                "company_href": "url string"
            }
        },
        "contact": {
            "id": int,
            "name": "string",
            "_info": {
                "contact_href": "url string"
            }
        },
        "site": {
            "id": int,
            "name": "string",
            "_info": {
                "site_href": "url string"
            }
        },
        "location": {
            "id": int,
            "name": "string",
            "_info": {
                "location_href": "url string"
            }
        },
        "department": {
            "id": int,
            "identifier": "string",
            "name": "string",
            "_info": {
                "department_href": "url string"
            }
        },
        "restrictLocationFlag": bool,
        "restrictDepartmentFlag": bool,
        "startDate": "date string",
        "noEndingDateFlag": bool,
        "cancelledFlag": bool,
        "sla": {
            "id": int,
            "name": "string",
            "_info": {
                "sla_href": "url string"
            }
        }
    }
]

当我从服务器后端接收数据时,我使用JSON.parse(response)我假设您正在使用 JaveScript 编写。 这是我为我的 webapp 编写的示例;

 $.get("/tictactoe/" + ID, {"thePosition": curr_line}, function(response){
        let x = JSON.parse(response); //here x is now a JSON object
          for(let i = 0; i <= 2; i++){
              for(let j = 0; j <= 4; j++){
                  console.log(x.gb[i][j]); //x holds a 2D-array called gb, 
                  //you can access it with x["gb"] or x.gb then its corresponding elements with [][]
              }
          }
          console.log(x["isValid"]); //isValid is the key, the value is a boolean true/false
        }
    });
