无法使用 Retrofit2 @GET 和 @Path 发送参数

Question

我想使用以下代码将带有 ID 参数的获取请求发送到我的 asp.net rest api。我要实现的格式是 https://randomwebapi.net/api/Tblathletes/id but instead the end result it always ends up being https://randomWebApi.net/api/Tblathletes/，其中 returns 所有运动员。它总是在末尾省略 ID。还有其他方法可以实现这种格式吗？

@GET("TblAthletes/{id}")
fun getAthlete(@Path("id")id:String?): Call<List<tblAthlete>>

调用代码如下

    private fun getAthletesdata(athleteID: String?) {
//        val filter = HashMap<String?,String?>()
//        filter.put("Id",athleteID)
        val call = mAPIService?.getAthlete(athleteID)
        call?.enqueue(object : Callback<List<tblAthlete>> {
            override fun onResponse(call: Call<List<tblAthlete>>, response: Response<List<tblAthlete>>) {
                val athletes:List<tblAthlete> = response.body()!!
                txtName?.setText((athletes[0].name))
                txtSurname?.setText((athletes[0].surname))
                txtDOB?.setText((athletes[0].dob))
                txtAthleteNumber?.setText((athletes[0].athletenumber))
                txtID?.setText((athletes[0].athleteidno))
            }

            override fun onFailure(call: Call<List<tblAthlete>>, t: Throwable) {
                Toast.makeText(this@EditAthleteActivity.context, t.message, Toast.LENGTH_SHORT).show()
            }
        })

    }

下面是我的asp.net代码

        [HttpGet]
        public async Task<ActionResult<IEnumerable<Tblathletegroup>>> GetTblathletegroup()
        {
            return await _context.Tblathletegroup.ToListAsync();
        }

        // GET: api/Tblathletegroups/5
        [HttpGet("{id}")]
        public async Task<ActionResult<Tblathletegroup>> GetTblathletegroup(string id)
        {
            var tblathletegroup = await _context.Tblathletegroup.FindAsync(id);

            if (tblathletegroup == null)
            {
                return NotFound();
            }

            return tblathletegroup;
        }

Answer 1

已将对象类型从 Call 更改为 Call。因为我只返回一行，所以返回的 Java 脚本不正确。现在可以使用了。
