使用HTTPClient的C#HTTP修补程序

谢谢,
尼克看看这一页:
但内容是这样的:
[ {
"op": "add",
"path": "/customerName",
"value": "Barry" }, {
"op": "add",
"path": "/orders/-",
"value": {
"orderName": "Order2",
"orderType": null
} } ]
我最终通过做几件事来解决我的问题:
- 没有依赖项,JsonPatchDocument似乎无法工作
services.AddControllers().AddNewtonsoftJson()代码>在Startup.cs中。这来自Nuget软件包“Microsoft.AspNetCore.Mvc.Newtonsoft.json”
- 有一种比@Neil的答案更容易创建数组的方法。这是:
var patchDoc=new JsonPatchDocument().Replace(o=>o.EntryTypeId,5)代码>
- 您需要此特定的媒体类型:
var content=newstringcontent(JsonConvert.SerializeObject(patchDoc),Encoding.UTF8,“application/json patch+json”)代码>
以下是完整的代码:
/// <summary>
/// Verify PUT /Entrys is working and returns updated records
/// </summary>
[Fact]
public async Task Patch()
{
var patchDoc = new JsonPatchDocument<EntryModel>()
.Replace(o => o.EntryTypeId, 5);
var content = new StringContent(JsonConvert.SerializeObject(patchDoc), Encoding.UTF8, "application/json-patch+json");
var httpResponse = await HttpClient.PatchAsync($"v1/Entry/1", content);
var actual = await httpResponse.Content.ReadAsStringAsync();
// Assert
Assert.Equal(HttpStatusCode.OK, httpResponse.StatusCode);
Assert.True(httpResponse.IsSuccessStatusCode);
}
/// <summary>
/// Endpoint to do partial update
/// </summary>
/// <returns></returns>
[HttpPatch("{entryId}")]
public async Task<ActionResult> Patch(int entryId, [FromBody] JsonPatchDocument<EntryModel> patchDocument)
{
if (patchDocument == null)
{
return BadRequest();
}
var existingEntry = _mapper.Map<EntryModel>(await _entryService.Get(entryId));
// Apply changes
patchDocument.ApplyTo(existingEntry);
var entry = _mapper.Map<Entry>(existingEntry);
var updatedEntry = _mapper.Map<Entry>(await _entryService.Update(entryId, entry));
return Ok();
}

JSONPATCH文档将不起作用。要使其工作,您必须添加媒体类型格式化程序
安装Microsoft.AspNetCore.Mvc.NewtonsoftJson
在startup.cs中,在AddControllers()之后添加->
.AddNewtonsoftJson(x=>
x、 SerializerSettings.ContractResolver=
新的CamelCasePropertyNamesContractResolver();})
如果需要将JSON作为默认媒体类型格式化程序。将其放在任何其他媒体类型的格式化程序之前
在做了大量的挖掘之后,我最终自己解决了这个问题。请参阅答案,了解如何使用TestServer实现它。
