使用 Retrofit 发送 POST 正文参数

Question

我有一个 api URL：https://orderingspace.com/api/search 机身参数： 纬度：48.8834553 日志：2.3399433 英里：6

你能告诉我这段代码哪里错了吗：

我的界面类：

public interface SearchAPI {
String BASE_URL = "https://orderingspace.com/api/";
@POST("search")
Call<SearchData> getSearchData(@Header("content-type") String contentType, @Body SearchDataRequest dataRequest);}

我的 SearchData 类（POJO）：

@Expose

SearchDataRequest POJO 类：

public class SearchDataRequest
{
private double lat;
private double log;
private int miles;

public double getLat() {
    return lat;
}

public SearchDataRequest(double lat, double log, int miles) {
    this.lat = lat;
    this.log = log;
    this.miles = miles;
}

public void setLat(double lat) {
    this.lat = lat;
}

public double getLog() {
    return log;
}

public void setLog(double log) {
    this.log = log;
}

public int getMiles() {
    return miles;
}

public void setMiles(int miles) {
    this.miles = miles;
}}

MainActivity 调用：

private void getSearchDataFromAPI()
{
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(SearchAPI.BASE_URL)
            .addConverterFactory(GsonConverterFactory.create()) //Here we are using the GsonConverterFactory to directly convert json data to object
            .build();


    SearchAPI api = retrofit.create(SearchAPI.class);
    SearchDataRequest searchDataRequest = new SearchDataRequest(48.8834553,2.3399433,6);

    api.getSearchData("application/x-www-form-urlencoded",searchDataRequest).enqueue(new Callback<SearchData>() {
        @Override
        public void onResponse(Call<SearchData> call, Response<SearchData> response) {
            Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(Call<SearchData> call, Throwable t) {
            Toast.makeText(MainActivity.this, "Fail", Toast.LENGTH_SHORT).show();
            System.out.println("Anshul : "+t.getMessage());
        }
    });
}

改造调用响应在此处发送失败响应。请在此处建议如何发送带有正文参数的 POST 请求。

您需要更改接口代码

public interface SearchAPI {
    String BASE_URL = "https://orderingspace.com/api";
    @FormUrlEncoded
    @POST("./search")
    Call<SearchData> getSearchData(@Field("lat") String lat,
                                   @Field("log") String log,
                                   @Field("miles") String miles);}

在主要活动中

SearchAPI api = retrofit.create(SearchAPI.class);
    api.getSearchData(lat,log,miles).enqueue(new Callback<SearchData>() {
        @Override
        public void onResponse(Call<SearchData> call, Response<SearchData> response) {
            Toast.makeText(MainActivity.this, "Success", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(Call<SearchData> call, Throwable t) {
            Toast.makeText(MainActivity.this, "Fail", Toast.LENGTH_SHORT).show();
            System.out.println("Anshul : "+t.getMessage());
        }
    });
