javascript - chrome 扩展的运行时错误

Question

前提:

尝试编写一个非常简单 chrome 扩展，作为测试，我想添加控制台日志记录以进行调试。但是，我一直收到这个错误

Unchecked runtime.lastError while running webRequestInternal.addEventListener: You need to request host permissions in the manifest file in order to be notified about requests from the webRequest API.

尝试:

我已经尝试添加我能找到的所有权限，但没有任何运气。有人可以帮帮我吗!

list 文件:

{
    "manifest_version": 2,
    "name": "test",
    "description": "testing app",
    "version": "1.0",
    "background": {
        "scripts": ["small.js"],
        "persistent": true
    },
    "permissions": ["webRequest", "webRequestBlocking", "tabs", "background", "storage"],
    "optional_permissions": ["http://*/*", "https://*/*", "<all_urls>"]
}

小.js

chrome.webRequest.onBeforeRequest.addListener(function(details) {
    if (details.method === "POST") {
        alert('here');
        console.log('logging here');

    } else if (details.method === "GET") {
        alert('there');
        console.log('logging there');
    }
}, {
    urls: ["<all_urls>"]
}, ["blocking", "requestBody"]);

我遇到了同样的问题，有类似的错误信息。 ma​​nifest.json 中的一个简单更新解决了这个问题。

permissions数组看起来像这样:

 "permissions": [
    "alarms",
    "contextMenus",
    "storage",
    "notifications",
    "webRequest",
    "webRequestBlocking",
    "<all_urls>"
  ],

添加 <all_urls>在permissions将解决您的问题。
