如何使用android改造在请求中正确发送正文？

Question

我在使用Retrofit Android lib的POSTMAN中得到的结果不一样。也许我做错了什么。

以下是我用来调用API的代码

    @Override
    protected Response doInBackground(Void... params) {
        Response<UserModel> response;
        try {
            LoginModel loginModel = new LoginModel("password", mEmail, mPassword, "Mobile", "123@abc");
            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl(Constants.BASE_URL)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();
            ServiceAPI serviceAPI = retrofit.create(ServiceAPI.class);
            Call<UserModel> call = serviceAPI.getToken(loginModel);

            try{
                response = call.execute();
                if (response.body() == null) {
                    Log.d(getString(R.string.app_name), response.errorBody().toString());
                    return response;
                } else {
                    return response;
                }
            }catch ( IOException e){
                Log.e(getString(R.string.app_name), e.getMessage());
            }


            Thread.sleep(2000);
        } catch (InterruptedException e) {
            return null;
        }
        return null;
    }

接口代码

下方

public interface ServiceAPI {
    @POST("Token")
    Call<UserModel> getToken(@Body LoginModel loginModel);
}

结果是：

类LoginModel.java

public class LoginModel {

@SerializedName("grant_type")
private String grantType;
private String username;
private String password;
@SerializedName("client_id")
private String clientId;
@SerializedName("client_secret")
private String clientSecret;

public LoginModel(String grantType, String username, String password, String clientId, String clientSecret) {
    this.grantType = grantType;
    this.username = username;
    this.password = password;
    this.clientId = clientId;
    this.clientSecret = clientSecret;
}

}

使用PostMan，结果会有所不同，进行令牌修正。

更新你的api

@FormUrlEncoded
@Post("Token")
Call<UserModel> getToken(@Field("grant_type") String grantType),
                         @Field("username") String userName,
                         @Field("password") String password
                         // etc
                       );

你的api电话

Call<UserModel> call = serviceAPI.getToken("password", mEmail, mPassword, ...);
