我有一个API。我正在尝试使用Ajax Jquery向我的api发送请求但是有问题。以下是我的Ajax请求。我正在以JSON格式发送数据,而且我需要添加两个请求标头(signedInUserId& accessToken)。但这不起作用。
$.ajax( {
type: "PUT",
contentType: 'application/json',
dataType: 'json',
beforeSend: function(xhr) {
xhr.setRequestHeader("signedInUserId", "1");
xhr.setRequestHeader("accessToken", "testtoken");
},
url: "url to my api",
data: JSON.stringify(data),
success: function( response ) {
// $('#successMessage').html(response);
},
complete: function() {
//message
}
});
虽然,如果我发送没有自定义标头的请求(signedInUserId& accessToken),并且在我的api控制器中我注释了自定义标头参数,它的工作绝对正常。下面是我的api控制器代码。
@RequestMapping(value = "test.json", method = { PUT })
public @ResponseBody
Map<String, ? extends Object> test(HttpSession session, @RequestHeader Integer signedInUserId, @RequestHeader String accessToken, @RequestBody MyTestModel myTestModel) {
// working
}
我很困惑为什么在发送自定义标头时它无法正常工作,发送自定义标头时是否有问题?

答案 0 :(得分:1)
显然问题是由于服务器响应中允许的标头。在我的服务器设置中,响应中允许的标头如下:
response.addHeader("Access-Control-Allow-Headers", "Content-Type, x-requested-with");
因此,我在允许的标头中添加了两个标头accessToken和signedInUserId,响应标头现在如下所示:
response.addHeader("Access-Control-Allow-Headers", "Content-Type, accessToken, signedInUserId, x-requested-with");
我想这就是为什么请求不超出预检请求(OPTION)的问题,因为我发送的标头不允许在服务器发送的响应标头中。如果我错了,请纠正我。
