我不确定我错过了什么。这段代码在我的本地开发机器上运行良好，当我将它部署到测试服务器上时，它不断抛出内部服务器错误或“消息”：“请求包含实体主体但没有 Content-Type 标头。推断的媒体类型此资源不支持“应用程序/八位字节流”。

我在这里做的一切正确吗？我只是插入简单的学生数据。这里一个 webapi 函数插入从两个对象（Student 和 StudentAddress）收集的数据。所以我将这两个对象存储到模型中，然后在 WebAPI 中使用它们。

我仍然想知道它是如何在我的本地机器上工作的。我已将所有文件部署到测试服务器。

学生模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace WebAPI.Models
{
    public class StudentModel
    {
        public Student Student { get; set; }
        public StudentAddress StudentAddress { get; set; }
    }
}

学生控制器

// POST: api/Student/InsertStudent
[ResponseType(typeof(StudentModel))]
[HttpPost]
public HttpResponseMessage InsertStudent(StudentModel studentModel)
{
    objCSADBEntities.Student.Add(studentModel.Student);
    objCSADBEntities.SaveChanges();

    objCSADBEntities.StudentAddress.Add(studentModel.StudentAddress);
    objCSADBEntities.SaveChanges();

    return Request.CreateResponse(HttpStatusCode.OK, studentModel);
}

在提交按钮上单击调用具有此代码的 Angularjs 提交函数

        var Student = {
                Name: $('#txt-FacilityLegalName').val().trim(),
                LastDate: '2016-12-09 05:24:55.407',
                SSMA_TimeStamp: '0x000000000778FCB1',
            };

            var StudentAddress = {
                AddressLine1: $('#txt-MailingAddressLine1').val().trim(),
                AddressLine2: ($('#txt-MailingAddressLine2').val().trim() != '' ? $('#txt-MailingAddressLine2').val().trim() : null),
                City: $('#txt-City').val(),
                State: $scope.objselectedstate.selectedstate.Value,
                ZipCode: $('#txt-ZipCode').val().trim(),
                ZipExt: ($('#txt-ZipExt').val().trim() != '' ? $('#txt-ZipExt').val().trim() : null),
                FullName: $('#txt-ContactFirstName').val().trim() + ' ' + $('#txt-ContactLastName').val().trim(),
                FirstName: $('#txt-ContactFirstName').val().trim(),
                LastName: $('#txt-ContactLastName').val().trim(),
                PhoneNumber: $('#txt-ContactPhone').val().trim(),
                Ext: ($('#txt-ContactPhoneExt').val().trim() != '' ? $('#txt-ContactPhoneExt').val().trim() : null),
                Fax: ($('#txt-ContactFax').val().trim() != '' ? $('#txt-ContactFax').val().trim() : null),
                Email: $('#txt-Email').val().trim()
            };
            var studentModelModel = { studentAddress: StudentAddress, student: Student };
            //Insert Student
            var insertStudent = providerService.insertStudent($scope.webAPIHostName, studentModelModel);
            insertStudent.then(function (response) {
                //success response here
            }, function (error) {
                // error handling here
            });

Angularjs Service.js

(function () {

    var app = angular.module('myApp');

    app.factory('studentService', ['$http', function ($http) {
        var factory = [];

        //Insert Student
        factory.insertStudent = function (webAPIHostName, studentModel) {
            var request = $http({
                method: 'POST',
                url: webAPIHostName + '/Provider/InsertStudent',
                data: studentModel
            })
            return request;
        }

        return factory;
    }
    ]);
})();

在控制台中，我看到了这个请求和响应
