[英]Disabling same origin policy for Chrome for local domains
我正在嘗試使用我正在開發的擴展程序Chrome 45.0.2454.85(64位)在Mac OS 10.10計算機上的本地* .dev樣式域上進行跨源請求。
我無法通過testbox.dev
收到消息,因為每次執行以下代碼時, status
值都為0
, responseText
始終為空。 嘗試這些連接時,檢查后台頁面的視圖將顯示控制台錯誤net::ERR_CONNECTION_REFUSED
。
我嘗試關閉所有Chrome實例,然后使用命令open -a Google\\ Chrome --args --disable-web-security
重新啟動,但仍然無法正常工作。
我嘗試了CORS
Chrome擴展程序,因此至少可以在本地服務器上進行測試,但這沒有用。
嘗試給我的實時api.example.com
URL加上https://www.corsproxy.com/
作為前綴,但請求從未完成。
嘗試使用cors-anywhere.herokuapp.com
前綴,但我得到了origin header required
的錯誤origin header required
。 為了解決這個問題,我嘗試使用xhr.setRequestHeader('Origin', http + '//' + window.location.host);
發送原始標頭xhr.setRequestHeader('Origin', http + '//' + window.location.host);
但Chrome不允許我繼續執行“ Refused to set unsafe header "Origin"
錯誤Refused to set unsafe header "Origin"
。
我嘗試將以下響應添加到服務器的Laravel控制器方法,但沒有幫助:
return Response::json($stock, 200, ['Access-Control-Allow-Origin' => '*']);

background.js
chrome.extension.onConnect.addListener(function(port) {
if (port.name != 'XHRProxy_')
return;
port.onMessage.addListener(function(xhrOptions) {
var http = (window.location.protocol === 'http:' ? 'http:' : 'https:');
var xhr = new XMLHttpRequest();
xhr.open(xhrOptions.method || "GET", http + xhrOptions.url, true);
//xhr.setRequestHeader('Origin', http + '//' + window.location.host);

xhr.setRequestHeader('X-API-key', 'JSFLIESLIFDFDHSLFEHSLFHSFH');
xhr.onreadystatechange = function() {
if (this.readyState == 4) {
port.postMessage({
status : this.status,
data : this.responseText,
xhr : this
});
}
};
xhr.send();
});
});
xhrproxy.js
var proxyXHR = {};
proxyXHR.get = function (url) {
var port = chrome.extension.connect({ name: 'XHRProxy_' });
var settings = {
method : 'GET',
url : url
};
var onSuccess;
var onFailure;
var self = {
onSuccess: function (callback) {
onSuccess = callback;
return self;
},
onFailure: function (callback) {
onFailure = callback;
return self;
}
};
port.onMessage.addListener(function (msg) {
if (msg.status === 200 && typeof onSuccess === 'function') {
onSuccess(msg.data, msg.xhr);
} else if (typeof onFailure === 'function') {
onFailure(msg.data, msg.xhr);
}
});
port.postMessage(settings);
return self;
};
content.js
// Localhost test domain.
proxyXHR.get('testbox.dev/api/XYZ/quantity')
.onSuccess(function (data) {
console.log(data);
})
.onFailure(function (data, xhr) {
console.log("HTTP Error while retrieving data.", data, xhr.status);
});
// Production server domain....produces same error as local domain test above.
proxyXHR.get('api.example.com/api/XYZ/quantity')
.onSuccess(function (data) {
console.log(data);
})
.onFailure(function (data, xhr) {
console.log("HTTP Error while retrieving data.", data, xhr.status);
});
如果將URL從testbox.dev
更改為生產URL api.example.com
我仍然會得到相同的跨源拒絕。
有什么主意在這里嗎?
net::ERR_CONNECTION_REFUSED
不是跨源錯誤。 您的https連接可能有問題。 您可以確保服務器上具有正確的證書,也可以切換到http。
請注意以下行:
var http = (window.location.protocol === 'http:' ? 'http:' : 'https:');
在后台頁面中沒有多大意義,因為該協議始終是chrome-extension:
