Question

我们有一个API，可以将参数作为json / application接收。我有一个Object类，想以json形式发送参数，并通过改造2进入该api。但是我有一个例外 java.lang.IllegalArgumentException：无法为com.account.sampark.ledger.model.UserRegister类（参数＃1）创建@Body转换器

public class UserRegister {
private String firstName;
private String lastName;
private String phone1;
private String phone2;
private String emailId;
private String passwd;
private String token;
private int roleId;

public UserRegister(String firstName, String lastName, String phone1, String phone2, String emailId, String passwd, String token) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.phone1 = phone1;
    this.phone2 = phone2;
    this.emailId = emailId;
    this.passwd = passwd;
    this.token = token;
}

public void setRoleId(int roleId) {
    this.roleId = roleId;
}

public int getRoleId() {
    return roleId;
}

}

ApiClient

public class ApiClient {

public static final String BASE_URL = ApiUrls.BASE_URL;

public static Retrofit retrofit = null;

public static Retrofit getApiClient() {
    if (retrofit == null) {
        Timber.plant(new Timber.DebugTree());

        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
            @Override
            public void log(String message) {
                Timber.i(message);
            }
        });

        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(loggingInterceptor)
                .connectTimeout(3000, TimeUnit.SECONDS).build();

        retrofit = new Retrofit.Builder().baseUrl(BASE_URL).
                client(client).addConverterFactory(LoganSquareConverterFactory.create()).build();
    }
    return retrofit;
}

}

@Headers("Content-Type: application/json")
@POST(USER + ApiUrls.CREATE)
Call<UserRole> registerUser(@Body UserRegister parm);

我从这里打电话

Call<UserRole> call = apiMobile.registerUser(params);

例外

我尝试删除@Headers（“ Content-Type：application / json”），但对我不起作用。See my json/application API here

Answer 1

您正在使用LoganSquareConverterFactory，因此需要像这样注释每个字段。查看官方文档Here

@JsonObject
public class UserRegister {

@JsonField
private String firstName;
@JsonField
private String lastName;
@JsonField
private String phone1;
@JsonField
private String phone2;
@JsonField
private String emailId;
@JsonField
private String passwd;
@JsonField
private String token;
@JsonField
private int roleId;

public UserRegister() { }

public void setRoleId(int roleId) {
    this.roleId = roleId;
}

public int getRoleId() {
    return roleId;

}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public String getPhone1() {
    return phone1;
}

public void setPhone1(String phone1) {
    this.phone1 = phone1;
}

public String getPhone2() {
    return phone2;
}

public void setPhone2(String phone2) {
    this.phone2 = phone2;
}

public String getEmailId() {
    return emailId;
}

public void setEmailId(String emailId) {
    this.emailId = emailId;
}

public String getPasswd() {
    return passwd;
}

public void setPasswd(String passwd) {
    this.passwd = passwd;
}

public String getToken() {
    return token;
}

public void setToken(String token) {
    this.token = token;
}

}

如何在改造2中将Object / Model类转换为json并发送json / Application后请求
