通过 POST 在 Retrofit Expected BEGIN_ARRAY 上发送 ArrayList 时出错，但在第 1 行第 1 列为 STRING

Question

当我尝试在 Retrofit 2 上使用@POST 将 ArrayList<> 发送到我的网络服务器时，ArrayList<> 保存在数据库中，但在 Android 日志中我得到以下错误：

java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 1 path $

我在这里看到了一些关于 SO 的问题，但我无法让它工作，但是我是一个初学者，有点迷路了。

这是 ArrayList：

ArrayList<ModelContact> listContact = new ArrayList<>();

    ModelContact c = new ModelContact("5", "OFF", "Test", "12134567", "14646", "email@email.com", "Adress");
    listContact.add(c);
    c = new ModelContact("6", "ON", "Test2", "12123456", "14646", "email@email.com", "Adress");
    listContact.add(c);

这是我的改装电话

Call<List<ModelContact>> callM = contactInterface.createRContact(listContact);
callM.enqueue(new Callback<List<ModelContact>>() {
    @Override

public void onResponse(Response<List<ModelContact>> response, Retrofit retrofit) {
        Log.i("TAG", "Success");
    }

    @Override
    public void onFailure(Throwable t) {
        Log.i("TAG", "Error: " + t.getMessage());
    }
});

这是我的界面：

public interface ContactInterface {

    @GET("recieve")
    Call<List<ModelContact>> getRContact();

    @POST("send")
    Call<List<ModelContact>> createRContact(@Body ArrayList<ModelContact> modelContact);
}

当我发出请求时服务器响应：

[{"id":"13","status":"ON","name":"Test","phone":"123","phone2":"1237855","email":"email@email.com","address":"adsfasd"},{"id":"14","status":"OFF","name":"Test","phone":"123","phone2":"125453","email":"email@email.com","address":"adsfasd"}]

ModelContatc class:

public class ModelContact {

    String id;
    String status;
    String name;
    String phone;
    String phone2;
    String email;
    String address;

    public ModelContact(String id, String status, String name, String phone,     String phone2, String email, String address) {
        this.id = id;
        this.status = status;
        this.name = name;
        this.phone = phone;
        this.phone2 = phone2;
        this.email = email;
        this.address = address;
    }

    public String getId() {
        return id;
    }

   public void setId(String id) {
        this.id = id;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getName() {
        return name;
    }

    public void setName(String nome) {
        this.name = name;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String phone2() {
        return phone2;
    }

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

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

}

正如 Blackbelt 所说，服务器没有响应 json，它的响应来自对数据库的查询，该查询返回 php 错误。
