登录的编写思路
首先，我们要向后台发送用户名和密码。
Serializable
public class LoginData
{
public string username;
public string password;
}
使用POST方法跟后台的登录方法通信
//url是通信url，jsonBody就是用户名密码
IEnumerator PostRequest(string url, string jsonBody)
{
using (UnityWebRequest request = new UnityWebRequest(url, "POST"))
{
byte\[\] bodyRaw = System.Text.Encoding.UTF8.GetBytes(jsonBody);
request.uploadHandler = new UploadHandlerRaw(bodyRaw);
request.downloadHandler = new DownloadHandlerBuffer();
request.SetRequestHeader("Content-type", "application/json");
yield return request.SendWebRequest();
if (request.result == UnityWebRequest.Result.Success)
{
Debug.Log("POST 成功：" + request.downloadHandler.text);
}
else
{
Debug.LogError("POST 失败：" + request.error);
}
}
}
那么现在我要把用户名密码都定义出来（先写死都是admin）
logindata = new LoginData();
logindata.username = "admin";
logindata.password = "admin";
然后把他转成json
string json = JsonUtility.ToJson(logindata);
然后调用刚才写的方法进行通信（url以后台给的为准 json就是刚刚转出来的json）
StartCoroutine(PostRequest("http://192.168.10.101:8086/api/auth/login", json));
显示成功了
我们需要有东西来接住他返回给我们的token、用户名等等信息
Serializable
public class LoginRequest
{
public int code;
public string message;
public data data;
}
Serializable
public class data
{
public string token;
public int userId;
public string username;
public string realName;
}
然后在成功的位置进行一个json转LoginRequest格式接收 并打印
string json = request.downloadHandler.text;
LoginRequest loginRequest = JsonUtility.FromJson<LoginRequest>(json);
Debug.Log(loginRequest.code);
Debug.Log(loginRequest.data.token);
整体代码：
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Networking;
public class trydothis : MonoBehaviour
{
public LoginData logindata;
void Start()
{
logindata = new LoginData();
logindata.username = "admin";
logindata.password = "admin";
string json = JsonUtility.ToJson(logindata);
StartCoroutine(PostRequest("http://192.168.10.101:8086/api/auth/login", json));
}
IEnumerator PostRequest(string url, string jsonBody)
{
using (UnityWebRequest request = new UnityWebRequest(url, "POST"))
{
byte\[\] bodyRaw = System.Text.Encoding.UTF8.GetBytes(jsonBody);
request.uploadHandler = new UploadHandlerRaw(bodyRaw);
request.downloadHandler = new DownloadHandlerBuffer();
request.SetRequestHeader("Content-type", "application/json");
yield return request.SendWebRequest();
if (request.result == UnityWebRequest.Result.Success)
{
Debug.Log("POST 成功：" + request.downloadHandler.text);
string json = request.downloadHandler.text;
LoginRequest loginRequest = JsonUtility.FromJson<LoginRequest>(json);
Debug.Log(loginRequest.code);
Debug.Log(loginRequest.data.token);
}
else
{
Debug.LogError("POST 失败：" + request.error);
}
}
}
}
