我在 azure 函数应用程序中序列化一个类,并通过对 Unity3d 中的帖子的响应来收集它。 这是一个 WebGL 项目,它在编辑器上运行良好,但在浏览器(chrome/firefox)上抛出异常:
using Newtonsoft.Json;
namespace ARTFunctions
{
public class LoginResponse
{
public string status { get; set; }
public string token { get; set; }
public string clientDB { get; set; }
public string clientTable { get; set; }
[JsonConstructor]
public LoginResponse() { }
}
public async Task<System.String> MyFunctionApp([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", "head", Route = null)] HttpRequest req, ILogger log)
{
LoginResponse logResp = new LoginResponse();
logResp.status = "Success";
logResp.clientDB = "userDB";
logResp.clientTable = "thisTable";
logResp.token="abc";
return JsonConvert.SerializeObject(logResp);
}
在Unity3d中,我收集序列化对象但得到构造函数错误:
using Newtonsoft.Json;
public class C_UnityClass: MonoBehaviour
{
public void AtButtonPressed()
{
UnityWebRequest www = UnityWebRequest.Post("https://xxx.azurewebsites.net/api/MyFunctionApp", formData);
yield return www.SendWebRequest();
string queryResult = www.downloadHandler.text;
var logResp = JsonConvert.DeserializeObject<LoginResponse>(queryResult);
debug.log("logResp"+logResp.token);
}
}
并使用 JsonContructor 创建非 Mono LoginResponse 类:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class LoginResponse
{
public string status { get; set; }
public string token { get; set; }
public string clientDB { get; set; }
public string clientTable { get; set; }
[JsonConstructor]
public LoginResponse (){}
//I also tried adding [JsonConstructor] to this constructor but throws error too
public LoginResponse(string status, string token, string clientDB, string clientTable)
{
this.status = status;
this.token = token;
this.clientDB = clientDB;
this.clientTable = clientTable;
}
}
错误: JsonSerializationException:无法找到用于类型 LoginResponse 的构造函数。类应该具有默认构造函数、带参数的构造函数或标有 JsonConstructor 属性的构造函数。路径“状态”,第 1 行,位置 10。 在 Newtonsoft.Json.Serialization.JsonSerializerInternalReader.CreateNewObject (Newtonsoft.Json.JsonReader 阅读器、Newtonsoft.Json.Serialization.JsonObjectContract objectContract、Newtonsoft.Json.Serialization.JsonProperty 容器成员、Newtonsoft.Json.Serialization.JsonProperty 容器属性、System.String id、 System.Boolean&createdFromNonDefaultCreator) [0x00000] in <00000000000000000000000000000000>:0
编辑:如果我对标记为 [JsonConstructor] 的 LoginResponse 使用单个空构造函数,我会得到异常,就好像构造函数在 azure 函数应用程序中失败一样。值得注意的是,从 Unity 编辑器运行时这一切都有效,但在浏览器上失败(针对 chrome/firefox 进行了测试):
"Unexpected end of Stream, the content may have already been read by another component. ","token":null,"clientDB":null,"clientTable":null}"
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class LoginResponse
{
public string status { get; set; }
public string token { get; set; }
public string clientDB { get; set; }
public string clientTable { get; set; }
[JsonConstructor]
public LoginResponse (){}
}
