使用 "Attachments - Create" API 将图像作为附件添加到 Azure DevOps 工作项在打开时不会呈现

Question

我浏览了其他几个 SO 页面，虽然它确实帮助我理解了将附件上传到工作项的工作原理，但在通过 [= 成功上传后，我仍然找不到查看所述附件的方法27=]，特别是如果它是图像。

API我用过：

要创建附件 link：https://docs.microsoft.com/en-us/rest/api/azure/devops/wit/attachments/create?view=azure-devops-server-rest-5.0

使用从上一个 API 响应中检索到的附件 URL，我在工作项更新 API 中使用了它，下面是一个片段：

api = f"https://dev.azure.com/{organization}/_apis/wit/workitems/{work_item_id}?api-version=6.0"
    file_size = os.path.getsize(file_path)
    payload = [
        {
            "op": "add",
            "path": "/relations/-",
            "value": {
                "rel": "AttachedFile",
                "url": attachment_url,
                "attributes": {
                    "comment": "Test",
                    "resourceSize": file_size
                }
            }
        }
    ]

在此之后，附件在工作项中可见，但单击时不会呈现图像。取而代之的是 window 打开并播放无限加载屏幕动画。它必须是导致此问题的图像编码，但是我找不到任何文档。

下面是将附件上传到现有工作项的完整代码。

def upload_attachment(file_path, work_item_id):

    # This part retrieves the Attachment URL
    headers = {
        "Accept": "application/json",
        "Content-Size": str(os.path.getsize(file_path)),
        "Content-Type": "application/octet-stream",
    }
    files = {'attachment': open(file_path, 'rb')}
    filename = os.path.basename(file_path)
    api = f"https://dev.azure.com/{organization}/{project}/_apis/wit/attachments?uploadType=Simple&fileName={filename}&api-version=1.0"
    resp = requests.post(url=api, files=files, headers=headers, auth=("","*fmhcstt*4nwadqy3uk*go23fga"))    
    attachment_url = resp.json()['url']

    # This part updates an existing work item, adding the attachment here.
    api = f"https://dev.azure.com/{organization}/_apis/wit/workitems/{work_item_id}?api-version=6.0"
    file_size = os.path.getsize(file_path)
    payload = [
        {
            "op": "add",
            "path": "/relations/-",
            "value": {
                "rel": "AttachedFile",
                "url": attachment_url,
                "attributes": {
                    "comment": "Test",
                    "resourceSize": file_size
                }
            }
        }
    ]
    headers = { 
        'Accept':'application/json', 
        'dataType': 'application/json-patch+json',
        'Content-type':'application/json-patch+json'
    }
    resp = requests.patch(url=api, headers=headers, json=payload, auth=("","*fmhcstt*4nwadqy3uk*go23fga"))

Answer 1

我发现问题出在 POST 请求上。

requests.post(url=api, files=files, headers=headers, auth=("","*fmhcstt*4nwadqy3uk*go23fga"))

应该是：

requests.post(url=api, data=files, ...
