Question

尽管没有与实际客户端调用和这些API方法的服务器实现有任何问题，但这种情况正在发生，任何建议都超过欢迎!!见下文

Angular Controller中的客户端功能实现

 function updateData() {
  dataService.put("/api/Product/" +
        vm.product.ProductId,
        vm.product)     
    .then(function (result) {
      // Update product object
      vm.product = result.data;

      // Get index of this product
      var index = vm.products.map(function (p)
      { return p.ProductId; })
          .indexOf(vm.product.ProductId);

      // Update product in array
      vm.products[index] = vm.product;

      setUIState(pageMode.LIST);
    }, function (error) {
      handleException(error);
    });
}

API实施

 [HttpPut()]
public IHttpActionResult Put(int id,
            Product product) {
  IHttpActionResult ret = null;
  PTCViewModel vm = new PTCViewModel();

  vm.Entity = product;
  vm.PageMode = PageConstants.EDIT;
  vm.Save();

  if (vm.IsValid) {
    ret = Ok(product);
  }
  else if (vm.Messages.Count > 0) {
    ret = BadRequest(ConvertToModelState(vm.Messages));
  }
  else {
    ret = NotFound();
  }

  return ret;
}

[HttpDelete()]
public IHttpActionResult Delete(int id) {
  IHttpActionResult ret = null;
  PTCViewModel vm = new PTCViewModel();

  // Get the product
  vm.Entity = vm.Get(id);
  // Did we find the product?
  if (vm.Entity.ProductId > 0) {
    // Delete the product
    vm.Delete(id);

    ret = Ok(true);
  }
  else {
    ret = NotFound();
  }

  return ret;
}

尝试将api端点的整个网址放在此处：

#define IDX(_M,_i,_j) (_M)[(_i) * N + (_j)] #define U(_i, _j) IDX(uL, _i, _j) __kernel void jacobi(__global VALUE* u, __global VALUE* f, __global VALUE* tmp, VALUE factor) { int i = get_global_id(0); int j = get_global_id(1); int iL = get_local_id(0); int jL = get_local_id(1); __local VALUE uL[(N+2)*(N+2)]; __local VALUE fL[(N+2)*(N+2)]; IDX(uL, iL, jL) = IDX(u, i, j); IDX(fL, iL, jL) = IDX(f, i, j); barrier(CLK_LOCAL_MEM_FENCE); IDX(tmp, i, j) = (VALUE)0.25 * ( U(iL-1, jL) + U(iL, jL-1) + U(iL, jL+1) + U(iL+1, jL) - factor * IDX(fL, iL, jL)); }

类似的东西：

"/api/Product/"

Answer 2

问题是使用新版本的Angular，只要Angular版本是1.x而不是2.x，所有API方法调用都是成功的，这是因为在Angular 2中进行PUT和DELETE调用的语法.x是不同的，这解释了为什么这些端点返回404 Not Found错误。

Angular API PUT-DELETE方法继续返回404 Not Found
