我想创建一个Google Chrome扩展程序,以便将数据从弹出窗体发送到localhost服务器。我创建了以下文件。一切正常但数据不会发送到localhost服务器。 有谁可以请帮助我,我的错误在哪里? 感谢。

的manifest.json

 {
  "manifest_version": 2,

  "name": "server Plug-ins",
  "description": "Send data to database",
  "version": "1.0",

  "icons": {
    "48": "icon.png"
  },

  "permissions": [
      "history",
      "browsingData",
        "tabs",
        "<all_urls>",
        "http://192.168.1.222/*",
        "storage"
  ],

  "browser_action": {
    "default_icon": "icon.png",
    "default_popup": "popup.html",
    "default_title": "Send data to server!"
  }

}

alert.js

document.write(" i am here . . .");

// Create our XMLHttpRequest object
var hr = new XMLHttpRequest();
// Create some variables we need to send to our PHP file
var url = "http://192.168.1.222/my_parse_file.php";
var fn = document.getElementById("name").value;
var ln = document.getElementById("details").value;
var vars = "name="+fn+"&details="+ln;
hr.open("POST", url, true);
// Set content type header information for sending url encoded variables in the request
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
// Send the data to PHP now... and wait for response to update the status div
hr.send(vars); // Actually execute the request

popup.html

<body>
    <label for="">Name</label><br><input type="text" id="name"> <br>
    <label for="">Details</label><textarea id="details"></textarea>
    <input id="clickme" name="myBtn" type="submit" value="click me">
    <script type="text/javascript" src="popup.js"></script>
</body>

popup.js

function hello() {
  chrome.tabs.executeScript({
    file: 'alert.js'    
  }); 
}
document.getElementById('clickme').addEventListener('click', hello);

我认为问题是如果input脚本正在运行,则无法在上下文中访问您的弹出式alert.js元素。

alert.js的上下文中,document指的是您在其中注入脚本的标签文档。

您可以执行以下操作以使其正常工作,并使用以下内容替换popup.js文件的内容:

function hello() {
    function contentScript(fn, ln){
        document.write(" i am here . . .");
        var hr = new XMLHttpRequest();
        var url = "http://192.168.1.222/my_parse_file.php";
        var vars = "name="+fn+"&details="+ln;
        hr.open("POST", url, true);
        hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        hr.send(vars);
    }

    var fn = document.getElementById("name").value;
    var ln = document.getElementById("details").value;

    chrome.tabs.executeScript({
        code: (contentScript.toString() + "\ncontentScript('" + fn + "', '" + ln + "');")
    }); 
}
document.getElementById('clickme').addEventListener('click', hello);

您可以删除alert.js文件,因为现在,扩展程序会直接注入JavaScript代码而不是注入文件。
