如何使用 Android 中的 Retrofit 从 API 获取数据

Question

I'm Trying to call API using retrofit in Android. Although I'm successfully able to api in response I'm getting Success Code = 200. But Apart from that Inside Json object Json array is null although while I'm trying to call same api in Postman I'm getting the desire result.

I'm trying to call using POST request

URL Request:- https://example.com/AD1/api/user/profile

I'm passing parameter in Body userid:- MFL176116

Below Postman

APIInterface.java

public interface APIInterface {

@POST("profile")
Call<ProfilePojo> getUserProfile(@Body ProfilePojo profilePojo);

}

ProfilePojo.java

public class ProfilePojo {

@SerializedName("message")
@Expose
private String message;
@SerializedName("code")
@Expose

@SerializedName("user_data")

private String userid;

public ProfilePojo(String userid) {
    this.userid = userid;
}

public String getUserid() {
    return userid;
}

public void setUserid(String userid) {
    this.userid = userid;
}
public String getMessage() {
    return message;
}

public void setMessage(String message) {
    this.message = message;

After debugging the code can see Message is success, code =200, but userdata size ==0 please help me to get rid of this error

Answer 1

Check again the way that you are calling the api, even your userid is getting null, probably it's getting null in the user, but the response is 200 bc there was no error, simply no user with that id.
