批处理请求-Dynamics CRM [英] Batch request - Dynamics CRM

问题描述

全部

我正在尝试使用以下源代码向Dynamics CRM实施批处理请求：

I am trying to implement a batch request to Dynamics CRM with the following source code:

public async Task<HttpResponseMessage> HttpPatchCrmApi(string resource, string data)
{
    string uniq = Guid.NewGuid().ToString();
    MultipartContent content = new MultipartContent("mixed", "batch_" + uniq);
    HttpRequestMessage batchRequest = new HttpRequestMessage(HttpMethod.Post, CrmBaseUrl + "/api/data/v8.0/$batch");
    HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, CrmBaseUrl + resource);
    request.Content = new StringContent(data, Encoding.UTF8, "application/json");
    HttpMessageContent query = new HttpMessageContent(request);

    content.Add(query);

    batchRequest.Content = content;

    HttpResponseMessage response = await RbWebApi.SendAsync(batchRequest);

    return response;
}

问题是我收到 400错误的请求

编辑：
如评论中的建议，此处是来自提琴手的请求的堆栈跟踪：

As suggested in the comments here is the stack trace of the request from fiddler:

POST https://Hidden.api.crm4.dynamics.com/api/data/v8.0/$batch HTTP/1.1
Authorization: Bearer eyJ0eXAiOiJKV.... very long string
Content-Type: multipart/mixed; boundary="batch_7b6e3c60-1284-4958-a39a-4653af21833c"
Host: Hidden.api.crm4.dynamics.com
Content-Length: 313
Expect: 100-continue

--batch_7b6e3c60-1284-4958-a39a-4653af21833c
Content-Type: application/http; msgtype=request

{"my_name":"slavi"}

推荐答案

我认为您的请求有误。
您必须像那样构建请求正文完全由Microsoft定义

I think your request is wrong. You must build the request Body EXACTLY like defined by Microsoft

这意味着空白行必须位于正确的位置，所有属性都必须存在于主体中（例如 --changeset_XXX例如，并且我认为您不满足此要求。

This means the Blank lines must be there at the right place all the attributes must exist in the body (like "--changeset_XXX" for example) and as I see you dont meet this requirements.

我只是在邮递员中针对我的CRM建立了一个Request，它起作用了：

I just build a Request in Postman against my CRM and it worked:

URL

https://yourTenant.api.crm.dynamics.com/api/data/v8.0/$batch

< hr>

标题

OData-MaxVersion:4.0
OData-Version:4.0
Accept:application/json
Authorization:Bearer aVeryLongStringTokenHere
Content-Type: multipart/mixed;boundary=batch_1234567

---

身体

--batch_1234567
Content-Type:multipart/mixed;boundary=changeset_555666

--changeset_555666
Content-Type:application/http
Content-Transfer-Encoding:binary
Content-ID:1

POST https://yourTenant.api.crm.dynamics.com/api/data/v8.0/accounts HTTP/1.1
Content-Type:application/json;type=entry

{name: 'BatchJobTest788'}
--changeset_555666
Content-Type:application/http
Content-Transfer-Encoding:binary
Content-ID:2

POST https://yourTenant.api.crm.dynamics.com/api/data/v8.0/accounts HTTP/1.1
Content-Type:application/json;type=entry

{new_name: 'BatchJobTest348'}
--changeset_555666--
--batch_1234567--

---

附加说明：

• 标题的内容类型保存您的BatchId


• 批次的内容类型保存您的ChangesetId（如果它是更改为数据）


• 开始编程REST之前调用尝试在像POSTMAN这样的REST工具中定义它们并使它们工作。然后在您的代码中构建工作请求。


• 此处一个很好的解释说明，用于CRM中的批处理

• The Content-Type of your Header holds your BatchId
• The Content-Type of your Batch holds your ChangesetId (if it is a change to data)
• Before starting to programm REST calls try to define them in a REST tool like POSTMAN and make them work. Then build the working request in your code.
• Here a good explanation-source for the batching in CRM
