ASP.NET Core WebAPI：不支持的媒体类型 - HTTP 415（不支持的媒体文件类型）
如何解决ASP.NET Core WebAPI：不支持的媒体类型 - HTTP 415？
我尝试创建一个新部门，但出现此错误：
{
"type":"https://tools.ietf.org/html/rfc7231#section-6.5.13","title":"Unsupported Media Type","status":415,"traceId":"|3361f693-4c3294040da78eae."
}
谁能告诉我为什么会出现这个错误？我也不能对部门做其他粗鲁的操作。

解决方法
删除 [ApiController] 并修复控制器操作：
[HttpGet]
public IActionResult Create()
{
var model=new Department();
return View(model);
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Create( Department department)
{
try
{
if (ModelState.IsValid)
{
_context.Add(department);
await _context.SaveChangesAsync();
return RedirectToAction(nameof(Index));
}
}
catch (DbUpdateException /* ex */)
{
//Log the error (uncomment ex variable name and write a log.
ModelState.AddModelError("","Unable to save changes. " +
"Try again,and if the problem persists " +
"see your system administrator.");
}
return View(department);
}
并查看
<form asp-action="Create" asp-controller"Departments" "method="post" >
<div asp-validation-summary="ModelOnly"></div>
<input type="hidden" asp-for="Id" value="@Model.Id" />
.....
</form>
415 Spring MVC和Rest Service不支持的媒体类型
我正进入（状态
415 Unsupported Media Type - The server refused this request because the request entity is in a format not supported by the requested resource for the requested method请求网址为：
http://localhost:8080/ngdemo/web/posts/review/80a5d7660cdb82a8ef9f8db79bb3c8ab14555377从弹簧控制器读取时出错；我检查了其他具有相同模式的控制器方法，它们工作正常，但不是我新介绍的这种方法。我找不到任何问题，能否请您提出我所缺少的内容？
我的控制器：
@RequestMapping(value = "/review/{key}", method = RequestMethod.GET, consumes = "", produces = "application/json")public@ResponseBodyList<Review> reviews(@PathVariable(value = "key") String key) { System.out.println("key : " + key); List<Review> reviewList = reviewService.getReviewsById(key); System.out.println("reviewList : " + reviewList.size()); return reviewList;}我的Angular Services.js：
services.factory(''PostFactory'', [''$resource'', function ($resource) {alert("I am here service");return { postmain: $resource(''/ngdemo/web/posts'', {}, { query: {method: ''GET'', isArray: true }, create: {method: ''POST''} }), reviews: $resource(''/ngdemo/web/posts/review/:key'', {}, { query: {method: ''GET'', params: {key: ''@key''} }, create: {method: ''POST''} }), postreview: $resource(''/ngdemo/web/posts/getreview'', {}, { query: {method: ''GET'', isArray: true }, create: {method: ''POST''} }), allresults: $resource(''/ngdemo/web/posts/result/:tag'', {}, { query: {method: ''GET'', params: {tag: ''@tag''} }, create: {method: ''POST''} })};}]）;
我的controller.js中的代码可以调用：
var reviewId = place.id;$scope.allreviews = PostFactory.reviews.query({key: reviewId})我找不到问题出在哪里，所以请大家看看并指出我想念的是什么？谢谢！
答案1
小编典典它通过添加以下内容起作用：
@Consumes("text/html") @Consumes("text/html")@RequestMapping(value = "/review/{key}", method = RequestMethod.GET, produces = "application/json")public@ResponseBodyList<Review> reviews(@PathVariable(value = "key") String key) {
415不支持的媒体类型-lightswitch 2012中的POST json到OData服务
使用JSON发布到OData服务时，出现“错误415：不支持的媒体类型”。
解决方案位于此较长文章的底部。
我可以使用JSON进行获取，但是一旦尝试POST，我就会收到此错误。
我也可以使用XML进行GET / POST，但是我需要使用json。
我认为此错误是指我的标头中的某些内容，而不是我的请求正文的json格式（在下面也可能是错误的），我尝试了多种变体导致相同的错误。
我一直在尝试使用Fiddler进行调试，以下是结果。

我不太明白为什么GET可以正常工作时POST不支持媒体类型的原因。我意识到我正在使用DataServiceVersion：1.0并已查找升级，但是我正在使用LightSwitch
2012并在引用新版本时遇到问题，而又没有破坏LightSwitch应用程序。我认为LightSwitch
2013使用的是较新的版本（？），但是对我而言，升级带来了新的（非技术性）挑战。我感觉自己正在绕过圈子，这是我的最后选择，与同事交谈后，我唯一的失败选择是在数据库上创建数据模型并在此数据库上创建OData服务。

此后，我尝试了Jen S提供的两个修复程序，现在得到错误：400错误的请求。

我是否正在解决这个问题，这仅仅是JSON请求主体结构不正确的问题吗？我尝试了几次尝试都没有成功，但是使用XML进行发布是可行的。

415不支持的媒体类型; Angular2到API
我是角度2的新手,我遇到了一个无法找到解决方案的问题：
当我尝试从角度2发布到API我得到 – 415不支持的媒体类型.
请帮助&如果需要更多细节,请告诉我.
当我尝试从角度2发布到API我得到 – 415不支持的媒体类型.
Angular 2代码：
onSubmit(value: any) {
// console.log(value.message);
let headers = new Headers({ 'Content-Type': 'application/json'});
let options = new RequestOptions({ headers: headers });
let creds = 'statusukNown';
let body = JSON.stringify(creds);
this.http.post('http://localhost:1318/api/ActionItem',creds)
.subscribe(
() => {console.log('Success')},err => {console.error(err)}
);
}
我的控制器代码：
// POST api/actionitem
[HttpPost]
public ActionItem Post( [FromBody]string str)// _id,string _status)
{
ActionItem item = new ActionItem( 313,str);
return item;
}
当我将控制器代码更改为不从主体获取数据时,它可以工作但是引用NULL.
我的API调用截图：
请帮助&如果需要更多细节,请告诉我.
解决方法
this.http.post('http://localhost:1318/api/ActionItem',body,options).map(response => response.json())
.subscribe(
() => {console.log('Success')}
);
415不支持的媒体类型jQuery Ajax
我正在使用Maven Rest API。通过jQuery Ajax调用发出POST请求时，出现415错误。请看一下我的代码。
function getUserDetails() {
var name = $("#name").val();
var mobile = $("#mobile").val();
var location = $("#location").val();
var email = $("#email").val();
var userDetails = {
"name": name,"mobile": mobile,"email": email,"location": location
};
return userDetails;
}
function createuser() {
sendRequest("registerProcess",getUserDetails(),"post");
}
function sendRequest(url,input,method) {
$.ajax({
url: url,async: false,data: JSON.stringify(input),error: function(response) {
//displayResponseMessage(response);
console.log("Error");
},success: function(response) {
console.log(" Successfull");
},type: method,headers: {
Accept: 'application/json;charset=utf-8',contentType: 'application/json;charset=utf-8'
},dataType: 'json'
});
}
这是我的控制器。这UserForm是POJO类别
@RequestMapping(value = "/registerProcess",method = RequestMethod.POST,consumes= MediaType.APPLICATION_JSON_VALUE)
public String addUser(@RequestBody UserForm user)
{
System.out.println("Inside Controller" );
String email = user.getEmail();
String mobile = user.getMobile();
System.out.println("Details :" + email + mobile);
return "welcome";
}
