Azure函数中的HTTP补丁

Question

我正在寻求一种在Azure函数中实现适当的HTTP路径的方法。我发现了正在检查每个属性的空的示例，并将其添加到实体中以进行补丁。我发现这不是理想的，而只是解决方法。我为HTTP触发函数（V2）找到的唯一签名是

public async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Anonymous, "HTTP VERB", Route = "")] HttpRequest req,
     ILogger log)
    {
    }

我需要通过" jsonpatchDocument "，而客户端将能够通过下面的补丁文档，

public async Task<IActionResult> Run(
    [HttpTrigger(AuthorizationLevel.Anonymous, "PATCH", Route = "")] **JsonPatchDocument<Customer> patch**,
 ILogger log)
{
}

PATCH /api/customer
[
    {
      "op": "replace",
      "path": "/firstname",
      "value": "Vijay"
    },
    {
      "op": "replace",
      "path": "/email",
      "value": "[e-mail]"
    },
]

以便我可以使用" patch.applyto（）"来路径属性。是否可以在Azure函数中执行？

我找到了解决方案。我无法通过" JSONPATCHDCUMEMER" 键入Azure函数，但我可以按照以下内容将请求主体解析为jsonpatchDocument，

FunctionName("PatchInstitute")]
    public async Task<IActionResult> PatchInstitute(
        [HttpTrigger(AuthorizationLevel.Anonymous, "patch", Route = ApiConstants.BaseRoute + "/institute/{instituteId}")] HttpRequest req,
        ILogger log, [Inject]IInstituteValidator instituteValidator, int instituteId, [Inject] IInstituteProvider instituteProvider)
    {
        try
        {
           //get existing record with Id here
            var instituteDto = instituteProvider.GetInstitueProfileById(instituteId);

            using (StreamReader streamReader = new StreamReader(req.Body))
            {
                var requestBody = await streamReader.ReadToEndAsync();
                //Deserialize bosy to strongly typed JsonPatchDocument
                JsonPatchDocument<InstituteDto> jsonPatchDocument = JsonConvert.DeserializeObject<JsonPatchDocument<InstituteDto>>(requestBody);
                //Apply patch here
                jsonPatchDocument.ApplyTo(instituteDto);
                //Apply the change
                instituteProvider.UpdateInstitute(instituteDto);
            }
            return new OkResult();
        }
        catch (Exception ex)
        {
            log.LogError(ex.ToString());
           // return Generic Exception here
        }
    }

和jsonpathdocument从客户端通过

[
    {
      "op": "replace",
      "path": "/isActive",
      "value": "true"
    }
]

在这里，您可以将任何字段传递到更新（补丁）
