Question

我正在使用GSON进行改造和解析结果。不知道为什么，但我收到了这个

预计BEGIN_ARRAY但在第1行第2栏路径为BEGIN_OBJECT

我知道这个错误意味着什么，但没有看到原因。

这是我的json回复

这是我的pojogenerator生成的模型。

public class DadataResponse {

@SerializedName("suggestions")
@Expose
private List<Suggestion> suggestions = new ArrayList<Suggestion>();

/**
 * 
 * @return
 *     The suggestions
 */
public List<Suggestion> getSuggestions() {
    return suggestions;
}

/**
 * 
 * @param suggestions
 *     The suggestions
 */
public void setSuggestions(List<Suggestion> suggestions) {
    this.suggestions = suggestions;
}

}

public class Suggestion {

@SerializedName("value")
@Expose
private String value;
@SerializedName("unrestricted_value")
@Expose
private String unrestrictedValue;
@SerializedName("data")
@Expose
private Data data;

/**
 * 
 * @return
 *     The value
 */
public String getValue() {
    return value;
}

/**
 * 
 * @param value
 *     The value
 */
public void setValue(String value) {
    this.value = value;
}

/**
 * 
 * @return
 *     The unrestrictedValue
 */
public String getUnrestrictedValue() {
    return unrestrictedValue;
}

/**
 * 
 * @param unrestrictedValue
 *     The unrestricted_value
 */
public void setUnrestrictedValue(String unrestrictedValue) {
    this.unrestrictedValue = unrestrictedValue;
}

/**
 * 
 * @return
 *     The data
 */
public Data getData() {
    return data;
}

/**
 * 
 * @param data
 *     The data
 */
public void setData(Data data) {
    this.data = data;
}

}

和数据类但它太大了，不需要在这里发布。

为什么我收到此错误？请帮忙

UPD

public ApiService(String URLSTRING){

    RequestInterceptor requestInterceptor = new RequestInterceptor() {
        @Override
        public void intercept(RequestFacade request) {
            request.addHeader("Authorization", "Token");
            request.addHeader("Content-Type","application/json");
            request.addHeader("Accept","application/json");
        }
    };

    RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint(URLSTRING)
                    .setRequestInterceptor(requestInterceptor)
            .setLogLevel(RestAdapter.LogLevel.FULL)
            .build();

    mApi = restAdapter.create(Api.class);
}

 public interface Api{

    @GET("/address")
    List<DadataResponse> getDadata(@Query("query") String query);

 }

Answer 1

更改

List<DadataResponse> getDadata(@Query("query") String query);

到

DadataResponse getDadata(@Query("query") String query);

预计BEGIN_ARRAY但在第1行第2栏路径为BEGIN_OBJECT

意味着它期待一个数组（因为你告诉它）但它收到了一个对象。

看起来您收到一个DadataResponse而不是其中的数组，因此您需要更新您的签名以符合现实。

GSON抛出预期的BEGIN_ARRAY但是BEGIN_OBJECT错误
