我正在尝试使用本地前缀为实际URL /端点的CORS在本地计算机上向外部URL运行ajax调用。但是，这会导致“缺少所需的请求标头。必须指定以下一项：origin，x-requested-with'错误。我已经手动设置了标头，如下面的代码所示，我只是不太明白为什么在显式定义“ requested-with”值后仍会发生这种情况。
// Set URL to the Create patient endpoint
const Url = 'https://cors-anywhere.herokuapp.com/https://staging.micromerchantsystems.com/mmsgatewayapistaging/api/patient/create';
// Define User data here ** Currently static information **
// Need to set variables based on input value to the correct identifier
// EX: "FirstName": $('#first_name').val();
const userData = {
"RequestingClient": {
"ClientId": "XXXXXXXXXX",
"ClientSecret": "XXXXXXXXXX",
"MemberId": "XXXXXXXXXX"
},
"Pharmacy": {
"IdentifierType": 2,
"Identifier": "5164086800"
},
"LastName": "Test",
"MiddleInitials": "X",
"FirstName": "Seth",
"Gender": "M",
"DOB": "01/01/1990",
"Email": "seth@test.com",
"PhoneNumber": "1234567890",
"MobileNumber": "1234567890",
"BusinessNumber": "1234567890",
"PatientIdentifiers": [
{ "IdentifierType": 1, "IdentifierType": "12345" }
],
"AddressInformation": {
"AddressType": 1,
"StreetLine1": "123 Test",
"StreetLine2": "",
"City": "Waco",

},
"ExternalPatientId": "1234567890",
"Timestamp": "2019-12-09T17:59:15.7624947Z"
};
// On button ajax call to create a new user with the above data
$('.btn').click(function () {
$.ajax({
url: Url,
type: "POST",
dataType: "json",
contentType: "application/json",
// set the request header authorization to the bearer token that is generated
headers: {
"X-Requested-With": "XMLHttpRequest",
"Authorization": "Bearer " + responseToken,
},
data: userData,
success: function (result) {
console.table(result);
$('.output_userInfo').html(result.ErrorMessage);
},
error: function (error) {
console.log(`Error ${error}`)
},
});
});

您正确设置了标题，但是根据cors-anywhere的作者，由于以下原因，您可能会遇到与发出请求相关的错误（即使在设置了适当的标题之后）：
基于对目标URL（https://staging.micromerchantsystems.com/的请求），我得到了一个IIS初始屏幕，因此您可能要验证所有内容是否都在运行。使用下面的一个非常简单的示例，我似乎能够访问正确的站点，但是收到401错误，表明我未经授权（但是我没有收到400要求的标头消息）：
$(function() {
$.ajax({
url: "https://cors-anywhere.herokuapp.com/https://staging.micromerchantsystems.com/mmsgatewayapistaging/api/patient/create",
type: "POST",
dataType: "json",
contentType: "application/json",
// set the request header authorization to the bearer token that is generated
headers: {
"X-Requested-With": "XMLHttpRequest"
},
success: function(result) {
console.log(result);
},
error: function(error) {
console.log(`Error ${error}`)
},
});
});
我想如果您包括适当的授权信息，您应该能够访问它。如果您仍然遇到问题，则可能需要consider reaching out to the author谁可能会帮助您进一步解决问题。

我做了一些进一步的研究，以便能够成功运行Postman代码并从中获得正确的答案。这是我用来正确运行API并跨域传递信息的代码。
// Set URL to the Create patient endpoint
const Url = "https://cors-anywhere.herokuapp.com/https://staging.micromerchantsystems.com/mmsgatewayapistaging/api/patient/create";
// On button ajax call to create a new user with the above data
$('.btn').click(function () {
// The input value variables NEED to be defined and set after the click function
// so that the value can be received and passed into the userData variable.
// Define User data here ** Currently static information **
// Need to set variables based on input value to the correct identifier
// EX: "FirstName": $('#first_name').val();
var user_firstName = $("#first_name").val();
const userData = {
"RequestingClient": {
"ClientId": "XXXXXX",
"MemberId": "XXXXXXX"
},
"Pharmacy": {
"IdentifierType": 2,
"Identifier": "XXXXXXX"
},
"LastName": "Test",
"MiddleInitials": "X",
"FirstName": user_firstName,
"Gender": "M",
"DOB": "01/01/1990",
"Email": "seth@test.com",
"PhoneNumber": "1234567890",
"MobileNumber": "1234567890",
"BusinessNumber": "1234567890",
"PatientIdentifiers": [
{ "IdentifierType": 1, "IdentifierType": "12345" }
],
"AddressInformation": {
"AddressType": 1,
"StreetLine1": "123 Test",
"StreetLine2": "",
"City": "Waco",
"State": "TX",
"ZipCode": "76710",
},
"ExternalPatientId": "1234567890",
"Timestamp": "2019-12-09T17:59:15.7624947Z"
};
// Using stringify is an important part in successfully passing the data
var userString = JSON.stringify(userData);
var userSettings = {
"async": true,
"crossDomain": true,
"url": Url,
"method": "POST",
"headers": {
"Content-Type": "application/json",
"Authorization": "Bearer " + responseToken,
"Accept": "*/*",
},
"data": userString
}
$.ajax(userSettings).done(function (response) {
console.table(response);
});
});
