我是新的改造,我有一个奇怪的问题。我得到以下错误--〉
应为开始_ARRAY,但在第1行第2列路径$处为BEGIN_OBJECT
然而,当我用curl命令访问端点时,我得到了一个json数组。
编辑
抱歉所有的编辑。我可能过早地提出了这个问题。我正在考虑删除不必要的代码片段,如果它们分散注意力的话。我把编辑放在顶部,这样你就不必向下滚动来查看最新的问题。我想我可能在最后一个问题上遇到了一些真实的的麻烦。
我发现使用不同的模型结构有助于json转换。
data class Jobs(
val job: List<JobPW>,
val status : String
)
到这个
data class JobApiModel(
val jobs: List<Job>,
val status: String
)
并使用匹配的元素创建了一个新的Job类
data class Job(
@SerializedName("city")
@field:Json(name = "city")
val city: String,
@SerializedName("job_id")
@field:Json(name = "job_id")
val job_id: Int,
@SerializedName("owner_id_map")
@field:Json(name = "owner_id_map")
val owner_id_map: Int,
@SerializedName("status")
@field:Json(name = "status")
val status: Int,
@SerializedName("title")
val title: String,
val workers: List<Worker>,
val posters: List<PosterWithWorker>
)
这是与JobPW相同的对象,但它被称为Job,这是属性的名称。您可以使用@SerializedName或类似的类名吗?JobPW是一个带有Job对象的Room关系,我不能将两个类都称为Job。处理此问题的最佳方法是什么?
所以两者
workers : List<Workers>
和
List<PosterWithWorker>
反序列化正确。其他字段都是null和空的。有什么我做错了或留下什么要做的吗?
编辑
我越来越接近了,似乎在数组周围添加了外部jobs对象之后,调用不再因异常而失败。相反,我从Retrofit response = Jobs(job = null)获得了一个null数组(jobs = null)。
我的房间刀对象在下面靠近底部的职位
由于某些原因,使用Retrofit时JSON响应看起来不同。
我应该提到这是来自一个Firebase实时数据库。当我使用curl时,我只看到数组,没有 Package 对象。

为什么你用
Response
类 Package 你的列表?也许你的Response
类和retrofit.Response
类不一样。在这种情况下检查你的导入。其次,检查添加到OkHttp的拦截器,看看是否没有损坏响应。
如果它们对你不起作用,告诉你如何从Retrofit获得JsonObject并显示代码。
编辑
这是一个坏的做法,使用同一个类为您的实体和响应。我写你的响应类。请尝试这一点,让我知道发生了什么。
并更新restApi如下:
