Question

我正在使用Visual Studio Online REST API，除了创建工作项外，似乎可以使一切工作正常。这不是内部部署安装。我按照这个例子发送一个PATCH但收到400 Bad Request错误。 VSO Create Work Item

Per fiddler，这是我的原始请求：

    PATCH https://xxx.visualstudio.com/defaultcollection/myproject/_apis/wit/workitems/$Task?api-version=1.0 HTTP/1.1
Accept: application/json
Authorization: Basic RmI3etc_etc_etc==
Content-Type: application/json-patch+json; charset=utf-8
Host: xxx.visualstudio.com
Content-Length: 101
Expect: 100-continue
Connection: Keep-Alive

{"op":"add","path":"/fields/System.Title","value":"JavaScript implementation for Microsoft Account"}

我得到的回复是400 Bad Request：

{"$id":"1","innerException":null,"message":"You must pass a valid patch document in the body of the request.","typeName":"Microsoft.VisualStudio.Services.Common.VssPropertyValidationException, Microsoft.VisualStudio.Services.Common, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03ftoken0a3a","typeKey":"VssPropertyValidationException","errorCode":0,"eventId":3000}

我不确定为什么补丁文件无效。

更新：每个请求，只需共享更多代码。我用自己的图书馆修补了一下。以下是我为项目轻松添加工作项（产品积压，错误等）所做的工作

public void AddWorkItem(VSOWorkItem workItem, string project)
    {
        Project = project;

        using (HttpClient client = new HttpClient())
        {
            client.DefaultRequestHeaders.Accept.Add(
            new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

            //Set alternate credentials
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
                Convert.ToBase64String(
                    System.Text.ASCIIEncoding.ASCII.GetBytes(
                        string.Format("{0}:{1}", UserName, Password))));

            var workItems = new List<VSOFieldPatch>();
            workItems.Add(new VSOFieldPatch() { Op = "add", Path = "/fields/" + VSOWorkItemFieldName.Title, Value = workItem.Title });
            workItems.Add(new VSOFieldPatch() { Op = "add", Path = "/fields/" + VSOWorkItemFieldName.Description, Value = workItem.Description });

            if (!string.IsNullOrEmpty(workItem.Tags))
                workItems.Add(new VSOFieldPatch() { Op = "add", Path = "/fields/" + VSOWorkItemFieldName.Tags, Value = workItem.Tags });

            var resp = AddWorkItemAsync(client, workItems, BaseProjectUrl + "wit/workitems/$" + workItem.WorkItemType.ToString());
        }

    }


 private async Task<String> AddWorkItemAsync(HttpClient client,
                                      IEnumerable<VSOFieldPatch> data,
                                      String apiUrl)
    {
        var responseBody = String.Empty;

        var temp = JsonConvert.SerializeObject(data);

        var content = new StringContent(
            JsonConvert.SerializeObject(data),
            Encoding.UTF8,
            "application/json-patch+json");

        try
        {
            using (HttpResponseMessage response = client.PatchAsync(apiUrl + ApiVersion, content).Result)
            {
                response.EnsureSuccessStatusCode();
                responseBody = await response.Content.ReadAsStringAsync();
            }
        }
        catch (Exception ex)
        {

        }

        return responseBody;
    }

这是我的PATCH扩展名：

public static class HttpClientExtensions
{

    public static Task<HttpResponseMessage> PatchAsync(this HttpClient client, string requestUri, HttpContent content)
    {
        HttpRequestMessage request = new HttpRequestMessage
        {
            Method = new HttpMethod("PATCH"),
            RequestUri = new Uri(client.BaseAddress + requestUri),
            Content = content,
        };

        return client.SendAsync(request);
    }


}

Answer 1

所有示例看起来都像是在发送一系列操作，而不仅仅是单个操作。我不知道这是否是一项要求。但也许它期望PATCH的主体是一个数组。

你可以尝试发送：

[{"op":"add","path":"/fields/System.Title","value":"JavaScript implementation for Microsoft Account"}]

看看它是否有效？

将application / json更改为application / json-patch + json似乎对我有用。
