我解析以上json數據的時候，報出

java.lang.illegalStateException:Expected BEGIN_OBJECT but was BEGIN_ARRARY at line 1 column 2 path$

發現自己解析的時候，使用的是對象，而非數組。但是以上json是數組形式

package com.android.csdnclient.bean;import com.google.gson.annotations.SerializedName;/*** 博客系統分類*/ public class ChannelBean {//分類id@SerializedName("id")private int id;//分類名稱@SerializedName("name")private String name;//分類別名@SerializedName("alias")private String alias;public String getAlias() {return alias;}public void setAlias(String alias) {this.alias = alias;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;} } package com.android.csdnclient.retrofit;import com.android.csdnclient.bean.ChannelBean;import java.util.List;import retrofit2.http.GET; import retrofit2.http.Query; import rx.Observable;/*** 網絡請求*/ public interface CSDNService {//獲取博客系統分類@GET("/blog/getchannel")Observable<List<ChannelBean>> getChannel(@Query("client_id") String client_id); }

Observable<List<ChannelBean>>這里必須使用對象容器來保存json數組。

總結
