是否可以将“ArrayBuffer”转换为某种“可读”格式，例如 JSON？

测试脚本：

<script>\ntry {\n   http = new ActiveXObject("Microsoft.XMLHTTP");   // Trying IE\n}\ncatch(e)    // Failed, use standard object \n{\n  http = new XMLHttpRequest(); \n}\n\nvar url = "http://localhost/test.htm";\nvar params = "param=abc&param2=62";\nhttp.open("POST", url, true);\n\nhttp.onreadystatechange = function() {//Call a function when the state changes.\n    if(http.readyState == 4 && http.status == 200) {\n        alert(\'send..\');\n    }\n}\nhttp.send(params);\n</script>\n

在后台（chrome 扩展）请求监听器： \n （从 test.htm 接收 xhr）

chrome.webRequest.onBeforeRequest.addListener(\n    function(details) {\n        console.log(details); \n},\n{\nurls: ["*://localhost/*"]\n},\n[\'requestBody\']);\n

控制台.日志结果：

Object {frameId: 0, method: "POST", parentFrameId: -1, requestBody: Object, requestId: …
