我已经为Google Chrome创建了一个简单的扩展程序,但是我在访问字典API时遇到了问题。该API运行在我的扩展运行所在的不同域上。 我已阅读有关此主题的所有StackOverflow线程,但无法解决此问题。Google Chrome扩展程序跨域XMLHttpRequest
我已将API的地址添加到权限。它没有工作,所以我将其替换为http://*/*
进行测试。我有以下manifest.json
:
{
"name": "web2memrise",
"version": "0.3",
"manifest_version": 2,
"permissions": ["http://*/*"],
"content_scripts": [{
"matches": ["<all_urls>"],
"js": ["jquery.min.js", "contentscript.js"],
"css": ["style.css"]
}],
"web_accessible_resources": ["script.js", "jquery.min.js"]
}
JavaScript函数中,我使API调用:
function translateCallback(json){
var translations = "";
for(var phrase of json){
translations += ", "+phrase.text;
}
translations = translations.substring(2).replace(", ", "\t")
popupContent(translations)
}
function translate(l1, l2, phrase){;
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://deu.hablaa.com/hs/translation/"+phrase+"/"+l1+"-"+l2+"/", true);
xhr.onreadystatechange = translateCallback
xhr.send();
}
但它给我下面的错误:
home:19 GET http://nxtck.com/as.php?zid=48360&clbk=nextperf net::ERR_BLOCKED_BY_CLIENTloadScript @ home:19window.onload @ home:37
