自定义响应的标头从transformResponse标头参数($ resource)中丢失 [英] Custom response's headers are missing from transformResponse headers argument ($resource)
问题描述
我已经为API端点定义了一个 $ resource
,该API端点返回一个包含多个 headers
的响应,但该响应位于
I've defined an $resource
to an API endpoint that returns a response containing several headers
but in the transformResponse
config function most of headers are missing from the headersGetter
function argument.
我该如何解决?
API的响应标头

var fileURL = URL.createObjectURL(file);

a.download = filename;
document.body.appendChild(a);

});
推荐答案
假设您正在进行CORS调用,则响应标头并未全部公开.服务器端需要在CORS过滤器中添加响应标头"Access-Control-Expose-Headers".
Assume you are making CORS calls, response headers are not all exposed. Server-side needs to add response header "Access-Control-Expose-Headers" in CORS filter.
例如要通过CORS调用读取名为"X-MY-HEADER1"和"X-MY-HEADER2"的自定义响应标头,请添加服务器标头
e.g. To read a custom response header named "X-MY-HEADER1" and "X-MY-HEADER2" with CORS call, server add header
访问控制公开标题:"X-MY-HEADER1,X-MY-HEADER2"
