Question

我有一个api链接我希望将参数传递给使用get retrofit方法。链接是

/ambulance/location?latitude=-1.6078289&longitude=38.779225&limit=10

我有下面的Retrofit 2课程：

@GET("/ambulance/location")
Call<AmbulanceModel> getNearbyAmbulances(@Query("latitude") String   latitude,
                                         @Query("longitude") String longitude,
                                         @Query("limit") int limit);

在我的主要活动中，我有以下代码;

Call<AmbulanceModel> call = api.getNearbyAmbulances(latitude + " ", longitude + " " , LIMIT);
    call.enqueue(new Callback<AmbulanceModel>() {
        @Override
        public void onResponse(Call<AmbulanceModel> call, Response<AmbulanceModel> response) {
            if (response.isSuccessful()) {
                ambulanceList = (ArrayList<AmbulanceList>) response.body().getData();
                for (int i = 0; i < ambulanceList.size(); i++) {
                    AmbulanceList ambulance = ambulanceList.get(i);
                    mAmbulanceAdapter.addAmbulance(ambulance);
                }
            }

问题是，我得到一个空白/空白页面（没有结果）。我认为Retrofit不会将参数发送到我的服务器api。我已经检查了logcat的错误，但没有任何帮助。

这是在retrofit get方法中将参数传递给api的正确方法吗？

模型类对象模型

public class AmbulanceModel implements Serializable {

private Integer success;
private String message;
private Object error;
private List<AmbulanceList> data = new ArrayList<AmbulanceList>(); //array
private Map<String, Object> additionalProperties = new HashMap<String, Object>();

/**
 *
 * @return
 * The success
 */
public Integer getSuccess() {
    return success;
}

/**
 *
 * @param success
 * The success
 */
public void setSuccess(Integer success) {
    this.success = success;
}

/**
 *
 * @return
 * The message
 */
public String getMessage() {
    return message;
}

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

/**
 *
 * @return
 * The error
 */
public Object getError() {
    return error;
}

/**
 *
 * @param error
 * The error
 */
public void setError(Object error) {
    this.error = error;
}

/**
 *
 * @return
 * The data
 */
public List<AmbulanceList> getData() {
    return data;
}

/**
 *
 * @param data
 * The data
 */
public void setData(List<AmbulanceList> data) {
    this.data = data;
}

public Map<String, Object> getAdditionalProperties() {
    return this.additionalProperties;
}

public void setAdditionalProperty(String name, Object value) {
    this.additionalProperties.put(name, value);
}

}

阵列模型

public class AmbulanceList implements Serializable {

private Integer id;
private String name;
private String locationName;
private String latitude;
private String longitude;
private String dateAdded;
private String distance;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();

/**
 *
 * @return
 * The id
 */
public Integer getId() {
    return id;
}

/**
 *
 * @param id
 * The id
 */
public void setId(Integer id) {
    this.id = id;
}

/**
 *
 * @return
 * The name
 */
public String getName() {
    return name;
}

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

/**
 *
 * @return
 * The locationName
 */
public String getLocationName() {
    return locationName;
}

/**
 *
 * @param locationName
 * The location_name
 */
public void setLocationName(String locationName) {
    this.locationName = locationName;
}

/**
 *
 * @return
 * The latitude
 */
public String getLatitude() {
    return latitude;
}

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

/**
 *
 * @return
 * The longitude
 */
public String getLongitude() {
    return longitude;
}

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

/**
 *
 * @return
 * The dateAdded
 */
public String getDateAdded() {
    return dateAdded;
}

/**
 *
 * @param dateAdded
 * The date_added
 */
public void setDateAdded(String dateAdded) {
    this.dateAdded = dateAdded;
}

/**
 *
 * @return
 * The distance
 */
public String getDistance() {
    return distance;
}

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

public Map<String, Object> getAdditionalProperties() {
    return this.additionalProperties;
}

public void setAdditionalProperty(String name, Object value) {
    this.additionalProperties.put(name, value);
}

}

Answer 1

检查您的基本URL（在创建Retrofit实例时使用）是否以“/”结尾。同时删除@GET注释中的第一个“/”：

@GET("ambulance/location")

Retrofit 2 @Get方法返回空白结果
