預期的BEGIN_OBJECT，但在第1行的STRING 128

Question

我的代碼使用Gson庫時出現問題。

當我跑我得到以下錯誤：

5596-5596/be.appmax.ktsjjt E/AndroidRuntime﹕ FATAL EXCEPTION: main 
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 128 

有沒有一種方法，以獲取有關錯誤的更多詳細？

這是我的JSON，我得到：

{"data":{"pro_email":"kevingoos@telenet.be","pro_last_name":"Goos","pro_sex":"M","pro_nickname":"Kevin Goos","pro_date_birth":"1996-04-23","pro_id":14,"pro_facebook_id":"1333567985","pro_first_name":"Kevin","pro_avatar":"http:\/\/graph.facebook.com\/1333567985\/picture","pro_date_updated":"2014-04-09 11:32:20"},"status":200} 

這是解析JSON類：

Response類：

public class ProfileResponse { 

@SerializedName("status") 
private int status; 
@SerializedName("data") 
private Profile data; 

public ProfileResponse() { 
} 

public int getStatus() { 
    return status; 
} 

public void setStatus(int status) { 
    this.status = status; 
} 

public Profile getData() { 
    return data; 
} 

public void setData(Profile data) { 
    this.data = data; 
} 
} 

型材類：

public class Profile implements Parcelable { 

//ID 
@SerializedName("pro_id") 
private int id; 
//FIELDS 
@SerializedName("pro_nickname") 
private String nickname; 
@SerializedName("pro_email") 
private String email; 
@SerializedName("pro_sex") 
private String sex; 
//TIME OR DATE 
@SerializedName("pro_date_birth") 
private DateTime birth_day; 
@SerializedName("pro_date_updated") 
private DateTime updated; 
@SerializedName("pro_avatar") 
private String avatar; 
@SerializedName("pro_first_name") 
private String firstName; 
@SerializedName("pro_last_name") 
private String lastName; 
@SerializedName("pro_facebook_id") 
private String facebookId; 

public Profile() { 

} 

public int getId() { 
    return id; 
} 

public void setId(int id) { 
    this.id = id; 
} 

public String getNickname() { 
    return nickname; 
} 

public void setNickname(String nickname) { 
    this.nickname = nickname; 
} 

public String getEmail() { 
    return email; 
} 

public void setEmail(String email) { 
    this.email = email; 
} 

public String getSex() { 
    return sex; 
} 

public void setSex(String sex) { 
    this.sex = sex; 
} 

public DateTime getBirth_day() { 
    return birth_day; 
} 

public void setBirth_day(String date) { 
    this.birth_day = JodaTimeUtil.getDateTimeFromString(date); 
} 

public DateTime getUpdated() { 
    return updated; 
} 

public void setUpdated(String date) { 
    this.updated = JodaTimeUtil.getDateTimeFromString(date); 
} 

public String getAvatar() { 
    return avatar; 
} 

public void setAvatar(String avatar) { 
    this.avatar = avatar; 
} 

public String getFirstName() { 
    return firstName; 
} 

public void setFirstName(String firstName) { 
    this.firstName = firstName; 
} 

public String getLastName() { 
    return lastName; 
} 

public void setLastName(String lastName) { 
    this.lastName = lastName; 
} 

public String getFacebookId() { 
    return facebookId; 
} 

public void setFacebookId(String facebookId) { 
    this.facebookId = facebookId; 
} 

@Override 
public String toString() { 
    return "Id: " + id + " - FBID: " + facebookId + " - NAME: " + nickname; 
} 

@Override 
public int describeContents() { 
    return 0; 
} 
} 

Re映入響應sponse CLASSE：

public static Profile getProfile(JSONObject response) throws IOException { 
    Profile profile = null; 

    // Map JSON to JAVA Objects 
    Type ProfileResponse = new TypeToken<ObjectResponse<String>>(){}.getType(); 
    ProfileResponse profileResponse = Shared.gson.fromJson(response.toString(), ProfileResponse.class); 

    if (profileResponse != null) { 
     // Status, Message, Data 
     int status = profileResponse.getStatus(); 

     Tools.LOG_DEBUG("ResponseBeers - getAll, Status: " + status); 

     if (profileResponse.getData() != null) { 
      profile = profileResponse.getData(); 
     } 
    } 
    return profile; 
}

發現我的問題：他不知道從喬達，日期時間庫DateTime類型。所以必須爲該類型註冊一個TypeAdapter。

Gson gson = new GsonBuilder().registerTypeAdapter(DateTime.class, new JsonDeserializer<DateTime>() { 
@Override 
public DateTime deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException { 
     return JodaTimeUtil.getDateTimeFromString(json.getAsString()); 
} 
}).create();
