改装退货
我正在使用服务器pc ip而不是localhost进行改造，因为改造不支持本地主机
改造客户
@POST("/Auth/authenticate")
Call<ApiResponse> createAccount(@Body Request user);
改造电话
request = new Request("01532383497", "123");
retrofit = RetrofitInstance.getInstance();
client = retrofit.create(APIClient.class);
client.createAccount(request).enqueue(new Callback<ApiResponse>() {
@Override
public void onResponse(Call<ApiResponse> call, Response<ApiResponse> response) {
String a=response.body().getType();
Log.d("d","d");
}
@Override
public void onFailure(Call<ApiResponse> call, Throwable t) {
Log.d("d","d");
}
});
请求对象
public class Request {
String Username;
String Password;
public Request(String Username, String Password) {
Username = Username;
Password = Password;
}
public String getUsername() {
return Username;
}
public void setUsername(String username) {
Username = username;
}
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
}
改造实例
public class RetrofitInstance {
public static Retrofit retrofit = null;
public static final String END_POINT = "http://192.168.0.104:50111/api/";
public static Retrofit getInstance(){
if (retrofit == null){
retrofit = new Retrofit.Builder().baseUrl(END_POINT)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
}
推荐答案
您应该了解，Android模拟器(虚拟设备)具有自己的网络.因此Google定义了一个神奇的IP地址"10.0.2.2".如果尝试浏览到该IP地址，则请求将被路由到主机的"127.0.0.1"回送适配器.但是，默认情况下，这种魔术不适用于IIS Express.
You should understand is that the Android emulator (a virtual device) has its own networking. So Google defines a magic IP address "10.0.2.2". If you try to browse to this IP address, the requests would be routed to "127.0.0.1" loopback adapter of the host machine. However, this magic won’t work for IIS Express by default.

首先，将您的192.168.0.104地址替换为 END_POINT 中的10.0.2.2.
First, replace your 192.168.0.104 address to 10.0.2.2 in END_POINT.
public static final String END_POINT = "http://10.0.2.2:50111/api/";

添加具有正确值的新绑定，并且主机名应为127.0.0.1.
Add new binding with correct values and the Hostname should be 127.0.0.1.
- 就我而言，我的访问点来自本地-
https://localhost:44317/api -
添加新绑定后，显示为
- In my case, my access point from the local -
https://localhost:44317/api after the add new binding, it shows as,

似乎Android魔术将Host标头设置为"127.0.0.1"，以便IIS Express可以以这种方式处理请求.
It seems that the Android magic sets Host header to "127.0.0.1" so that IIS Express can process the requests in this way.
