大家好， 美好的一天！ 我在使用剩余的api时遇到关于PutAsJsonAsync和PostAsJsonAsync的问题：afs-test-redis99.afservice:8080/site/ 操作：PUT 名称：addItem 路径：/ api / cart / {id} / item 查询：商店类型 参数：item，quantity，key 请求正文：AnyObject（可选） 示例：在我的邮递员中，当我尝试添加/添加新项目时它工作正常： afs-test-redis99.afservice:8080/site / api / cart / 51 / item？item = COM1& store = PCM& type = active& quantity = 5 但是当我试图在我的mvc存储​​库类

Hi to all, Good day! I'm having an issue regarding the PutAsJsonAsync and PostAsJsonAsync in consuming the rest api: "afs-test-redis99.afservice:8080/site/" Operations: PUT Name: addItem Path: /api/cart/{id}/item Query: store type Parameters: item, quantity,key Request Body: AnyObject(optional) Example: In my postman, it is working correctly, when I tried to put/add new item: "afs-test-redis99.afservice:8080/site/api/cart/51/item?item=COM1&store=PCM&type=active&quantity=5" But when I tried to implement this in my mvc repository class

public async Task<Uri> SaveItemAsync(Item item) { client.BaseAddress = new Uri("afs-test-redis99.afservice:8080/site/"); client.DefaultRequestHeaders.Accept.Clear(); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue( "application/json")); HttpResponseMessage response = await client.PutAsJsonAsync($"api/cart/{item.ID}/item?",$"item={item.ProductID}&store=PCM&type=active&{item.Quantity}"); response.EnsureSuccessStatusCode(); // return URI of the created resource. return response.Headers.Location; }

结果错误是：

The result error is:

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: { Connection: close Date: Tue, 13 Jun 2017 00:23:21 GMT Server: Apache-Coyote/1.1 Content-Length: 1062 Content-Language: en Content-Type: text/html; charset=utf-8 }}

任何人都可以帮助我解决我的代码出了什么问题，抱歉我是新来的在我的客户端应用程序中使用web api。非常感谢您提前。 我尝试过： 它在邮递员中正常工作：

Can anyone assist me what's wrong on my code, sorry I'm new to consuming the web api in my client application. Thank you very much in advance. What I have tried: It is working correctly in postman:

"afs-test-redis99.afservice:8080/site/api/cart/51/item?item=COM1&store=PCM&type=active&quantity=5" But when I tried to implement this in my mvc repository class (c#) public async Task<Uri> SaveItemAsync(Item item) { client.BaseAddress = new Uri("afs-test-redis99.afservice:8080/site/"); client.DefaultRequestHeaders.Accept.Clear(); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue( "application/json")); HttpResponseMessage response = await client.PutAsJsonAsync($"api/cart/{item.ID}/item?",$"item={item.ProductID}&store=PCM&type=active&{item.Quantity}"); response.EnsureSuccessStatusCode(); // return URI of the created resource. return response.Headers.Location; }

推荐答案

api / cart / {item.ID} / item？， "api/cart/{item.ID}/item?",

\"item={item.ProductID}&store=PCM&type=active&{item.Quantity}）; response.EnsureSuccessStatusCode（）; //返回已创建资源的URI。 返回response.Headers.Location; } "item={item.ProductID}&store=PCM&type=active&{item.Quantity}"); response.EnsureSuccessStatusCode(); // return URI of the created resource. return response.Headers.Location; }

结果错误是：

The result error is:

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.StreamContent, Headers: { Connection: close Date: Tue, 13 Jun 2017 00:23:21 GMT Server: Apache-Coyote/1.1 Content-Length: 1062 Content-Language: en Content-Type: text/html; charset=utf-8 }}
