以WhatsApp网页版为例。
报错：
Refused to load the script ‘https://xxx/xxx.js’ because it violates the following Content Security Policy directive: “script-src ‘self’ data: blob: ‘unsafe-eval’ ‘unsafe-inline’ https://ajax.googleapis.com https://api.search.live.net https://maps.googleapis.com https://www.youtube.com https://s.ytimg.com”. Note that ‘script-src-elem’ was not explicitly set, so ‘script-src’ is used as a fallback.
破解：
chrome.webRequest.onHeadersReceived.addListener(
function (details) {
console.log(‘Disabled CSP’, details)
for (var i = 0; i < details.responseHeaders.length; i++) {
if (details.responseHeaders[i].name.toLowerCase() === ‘content-security-policy’) {
details.responseHeaders[i].value = ”
}
}
return {
responseHeaders: details.responseHeaders
}
},
{
urls: [
‘*://*.whatsapp.com/*’
]
},
[‘blocking’, ‘responseHeaders’]
)
