[英]Problems with chrome.proxy API
我正在嘗試使用chrome代理api,但是由於某些原因,我一直收到此錯誤。 我以為我做得對,但我猜不是:/
這是我的代碼...
var proxy_type;
var proxy_port;
var proxy_ip;
chrome.storage.sync.get(['proxy_type', 'proxy_port', 'proxy_ip', 'proxy'], function(items) {
console.log('Settings retrieved', Object.values(items));
proxy_type = items.proxy_type; //this is equal to socks5
proxy_ip = items.proxy_ip; //this is equal to 66.78.44.221
proxy_port = parseInt(items.proxy_port); //this is equal to 58124
});
var config = {
mode: "fixed_servers",
rules: {
singleProxy: {
scheme: proxy_type,
host: proxy_ip,
port:proxy_port
},
bypassList: ["foobar.com"]
}
};
chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
console.log(sender.tab ?
"from a content script:" + sender.tab.url :
"from the extension");
if (request.greeting == "connect"){
console.log('setting proxy');
console.log(proxy_ip); //shows 66.78.44.221 in the log...
chrome.proxy.settings.set(
{value: config, scope: 'regular'},
function() {});
}
});
但是,無論何時運行此代碼,我都會收到錯誤: Error in event handler for runtime.onMessage: Error: Invalid value for argument 1. Property 'value.rules.singleProxy.host': Property is required.
如果我僅通過鍵入值而不是使用變量來設置scheme,host和port的值,則它可以工作。
那我為什么會收到這個錯誤?
該錯誤表明配置中的host字段可能未定義。 由於chrome.storage.sync.get
是異步的,因此我希望在定義代理參數之前先構造配置對象。
您可以在回調中構造config並檢查它是否在消息處理程序中定義:
var config;
chrome.storage.sync.get(['proxy_type', 'proxy_port', 'proxy_ip', 'proxy'], function(items) {
console.log('Settings retrieved', Object.values(items));
config = {
mode: "fixed_servers",
rules: {
singleProxy: {
scheme: items.proxy_type,
host: items.proxy_ip,
port: parseInt(items.proxy_port)
},
bypassList: ["foobar.com"]
}
};
});
chrome.runtime.onMessage.addListener(
function(request, sender, sendResponse) {
if (!config) {
console.log('proxy config not defined');
return;
}
console.log(sender.tab ?
"from a content script:" + sender.tab.url :
"from the extension");
if (request.greeting == "connect"){
console.log('setting proxy');
console.log(config); //shows 66.78.44.221 in the log...
chrome.proxy.settings.set(
{value: config, scope: 'regular'},
function() {});
}
});
