无法在 TFS 中使用批处理操作创建批处理工作项

Question

我在尝试使用批量创建方法创建工作项时出现以下错误

错误 1

"Message":"No MediaTypeFormatter is available to read an object of type 'JsonBatchHttpRequest' from content with media type 'application/json-patch+json'."

错误 2

{"count":1,"value":{"Message":"One or more errors occurred."}}

我已参考此文档https://www.visualstudio.com/en-us/docs/integrate/api/wit/batch from Microsoft . and my question on stackoverflaw

我试过用以下方法发送数据

• "json: x"
• "body: x:"
• "body:JSON.stringify(x)"
• "json:[body:x]"

我已经尝试将 "application/json-patch+json" 和 "application/json"（推荐作为 MIcrosoft 文档）作为 Content-Types

我已经厌倦了 Post（推荐作为 MIcrosoft 文档）和补丁方法

此错误没有可用的参考资料，因此我对此很烂point.What这里可能有误，请帮助..

public batchOperation(  ):q.Promise<boolean>{   

        let deferred = q.defer<boolean>();

        try {            
            var batchCreateUrl = this.collectionURL+"/_apis/wit/$batch?api-version=1.0";

   var x= {
        method:"PATCH",
        uri:"/VSTS_TFS_Test/_apis/wit/workItems/$Bug?api-version=1.0",
        headers:{
                "Content-Type":"application/json-patch+json"
            },
    body:[
            {   "op":"add", 
                "path": "/fields/System.Tags", 
                "value":"tg;tg1;tg2" 
            },
            { 
                "op": "add", 
                "path": "/fields/System.Title", 
                "value": "Some Title Text "
            },
            { 
                "op": "add", 
                "path": "/fields/System.Description", 
                "value":"this is description"
            }
        ]
 }

            var options = {            
                url: batchCreateUrl,
                username: this.username,
                password: this.password,
                domain: this.domain,
                method: 'PATCH',
                headers: {
                'Content-Type': 'application/json-patch+json'
            },

                body: x
            };

            httpntlm.patch(options, function(err,res) {

                if(err) {
                    return deferred.reject(false);}
                else{
                    console.log("Patch Complete");
                    console.log(res.body);
                    deferred.resolve(true);
                }
            });
        } catch (error) {
            console.log("Failed to Perform Batch Operation ")
            deferred.reject(false);
        }
        return deferred.promise;
    }

Answer 1

您需要使用 "application/json" 作为内容类型和 post 方法，就像 tutorial of Microsoft documentation 描述的那样。

由于您使用的是 httpntlm，您可以包括以下选项：

1. json: if you want to send json directly (content-type is set to application/json)
2. files: an object of files to upload (content-type is set to multipart/form-data; boundary=xxx)
3. body: custom body content you want to send. If used, previous options will be ignored and your custom body will be sent. (content-type will not be set)

如果您使用正文，您之前的选项将被忽略（内容类型将丢失），这可能会导致问题。尝试直接使用 json.
