Question

这是我的错误：

D/Retrofit: java.lang.IllegalArgumentException: Sales.updateDeliveryLine: Only one HTTP method is allowed. Found: PUT and PUT.
                                                                                at retrofit.RestMethodInfo.methodError(RestMethodInfo.java:123)

                                                                                at retrofit.RestAdapter$RestHandler$2.obtainResponse(RestAdapter.java:278)
                                                                                at retrofit.CallbackRunnable.run(CallbackRunnable.java:42)

                                                                                at java.lang.Thread.run(Thread.java:818)

这是我在Android Studio中的代码：

 @PUT("/salesinsight/GetDeliveryScheduleLineRow/")
        public void updateDeliveryLine(@Path("id") int id, @Body API_DeliveryScheduleLines api_deliveryScheduleLines,
                                       Callback<API_DeliveryScheduleLines> callback);

这是我在Web Api中的代码：

// PUT: api/GetDeliveryScheduleLineRow/5
    [ResponseType(typeof(void))]
    public IHttpActionResult PutDelivery_Schedule_Lines(int id, Delivery_Schedule_Lines delivery_Schedule_Lines)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        if (id != delivery_Schedule_Lines.ID)
        {
            return BadRequest();
        }

        db.Entry(delivery_Schedule_Lines).State = EntityState.Modified;

        try
        {
            db.SaveChanges();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!Delivery_Schedule_LinesExists(id))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return StatusCode(HttpStatusCode.NoContent);
    }

每次尝试更新错误时都会显示。

首先，在您的PUT方法中，您将id作为Integer传递。但是你没有在你的API路径中提到id，这是缺少的。希望它有所帮助。

 @PUT("/salesinsight/GetDeliveryScheduleLineRow/{id}")
    public void updateDeliveryLine(@Path("id") int id, @Body API_DeliveryScheduleLines api_deliveryScheduleLines,
                                   Callback<API_DeliveryScheduleLines> callback);

Android返回“retrofit.RetrofitError：只允许一个HTTP方法。发现：PUT和PUT”
