从我的 Android 应用程序发送到 Gin 时失败，但从 Postman 发送到 Gin 时成功

我不太确定哪一方是问题的原因，但似乎Gin收到了请求，但不允许来自android应用的请求.我试图POST到的端点与一个具有类型字段的整体模型相关，而该类型字段"告诉"Gin哪些是必需的字段(我的工作流对于我的系统的这一部分来说有点复杂).在android端，我有一个对应于这个整体模型的模型，因为我在应用程序中使用它来做一些东西.以前，我只需要从服务器获取与整体模型相关的数据.现在，我正在为它执行POST.服务器型号的android副本如下所示:

@Entity(tableName = "thing", indices = [Index(value = ["id"], unique = true)])
data class Thing(
    @PrimaryKey(autoGenerate = false) @ColumnInfo(name = "id") var id: String,
    @SerializedName("CreatedAt") @ColumnInfo(name = "created_at") var created_at: String,
    @ColumnInfo(name = "name") var name: String,
    @ColumnInfo(name = "type_id") var type_id: String,
    @ColumnInfo("type") var type: ThingType? = null,
    @ColumnInfo(
        name = "some_field_1",
        defaultValue = "0"
    ) var some_field_1: Float = 0.0f,
    @ColumnInfo(
        name = "some_field_2",
        defaultValue = "0"
    ) var some_field_2: Float = 0.0f,
    @ColumnInfo(
        name = "some_field_3",
        defaultValue = "0"
    ) var some_field_3: Float = 0.0f,
    @ColumnInfo(
        name = "some_field_4",
        defaultValue = "0"
    ) var some_field_4: Float = 0.0f,
    @ColumnInfo(
        name = "some_field_5",
        defaultValue = "0"
    ) var some_field_5: Float = 0.0f,
    @ColumnInfo(
        name = "parent_id",
        defaultValue = "0"
    ) var parent_id: String
)

然后，这是整体式服务器模型的一个片段:

type Thing struct {
    gorm.Model
    ID            string    `gorm:"primarykey; size:40;" json:"id"`
    Name          string    `json:"name"`
    TypeId        string    `gorm:"size:40; index; not null" json:"type_id"`
    Type          Type      `gorm:"foreignKey:TypeId; constraint:OnUpdate:CASCADE,OnDelete:CASCADE" json:"type"`
    SomeField1    float32   `json:"some_field_1"`
    SomeField2    float32   `json:"some_field_2"`
    SomeField3    float32   `json:"some_field_3"`
    SomeField4    float32   `json:"some_field_4"`
    SomeField5    float32   `json:"some_field_5"`
    ParentId      float32   `json:"parent_id"`
}

然后I POST a Thing使用Retrofit，如下所示:

@POST("/thing_info")
suspend fun postThingInfo(
    @HeaderMap headers: Map<String, String>,
    @Body data: Thing
): Response<Thing>

val thing =
    Thing(
        "",
        "",
        name = binding.txtName.text.toString(),
        type_id = typeId,
        some_field_1 = binding.txtSomeField1.text.toString()
            .toFloat(),
        some_field_2 = binding.txtSomeField2.text.toString()
            .toFloat(),
        some_field_3 = binding.txtSomeField3.text.toString()
            .toFloat(),
        parent_id = parentId,
    )

//then the usual Retrofit boilerplate

使用这些代码，我只看到请求得到201，但没有错误，即使我为进程中出现的每个错误对象返回了一些东西.

以下是Golang代码btw:

ginGine.POST("/thing_info", func(ctx *gin.Context) {
    errMsg := clnHelpers.ValidateAccessToken(ctx.GetHeader("access_token"))

    if errMsg != "" {
        ctx.JSON(http.StatusBadRequest, gin.H{
            "error": errMsg,
        })
        return
    }

    var thing_info models.Thing

    err := ctx.ShouldBind(&thing_info)
    if err != nil {
        ctx.JSON(http.StatusBadRequest, gin.H{
            "error": err.Error(),
        })
        return
    }

    data := &pb.ThingInfo{
        Name:                        thing_info.Name,
        TypeId:                      thing_info.TypeId,
        //other field association
    }

    res, err := srvClient.service.CreateThingInfo(ctx, &pb.CreateThingInfoRequest{
        ThingInfo: data,
    })

    if err != nil {
        ctx.JSON(http.StatusBadRequest, gin.H{
            "error": err.Error(),
        })
        return
    }

    ctx.JSON(http.StatusCreated, gin.H{
        "thing_info": res.ThingInfo,
    })
})
