我正在编写一个访问来自http://labs.bible.org/的圣经段落的API,并且JSON响应没有“响应”头或任何层次结构名称而回来。 Firebug显示我的GET请求回到200状态,但响应选项卡始终为空。如果我直接在浏览器中输入url,我会得到我想要的结果,但我不知道如何处理这样的JSON。例如:http://labs.bible.org/api/?passage=luke+9&formatting=full&type=json。无标题JSON响应
这就是JSON的样子。

"bookname": "Luke",
"chapter": "9",
"verse": "1",
"text": "<t /><p class=\"bodytext\">After<n id=\"1\" /> Jesus<n id=\"2\" /> called<n id=\"3\" /> the twelve<n id=\"4\" /> together, he gave them power and authority over all demons and to cure<n id=\"5\" /> diseases,",

那么如何编写访问和解析JSON的代码,以及如何循环遍历所有结果呢?
这是我用来获取和解析JSON功能:
function callApi(argument, callBack){
var requestUrl = apiUrl+argument+type;
try{
var request = new XMLHttpRequest();
request.addEventListener("readystatechange",
function() {callBack(request);}, false);
request.open("GET", requestUrl, true);
request.setRequestHeader("Accept", "application/json; charset=utf-8");
request.send();
}//end try
catch(exception){
alert("Request Failed");
}//end catch
}//end function callApi
function parseData(request){
if(request.readyState==4 && request.status==200){
var data = JSON.parse(request.responseText);
displayNames(data);
}//end if
}// end function parseData
大多数语言都有一个JSON解析器,这将有助于您访问JSON元素。你在用什么语言?对于java,有GSON,对于Python和JavaScript,有内置的json支持,Objective-C有JSONKit,Perl有JSON包等等。 – PaulProgrammer 2013-04-09 17:19:49
这个API是用某种编程语言编写的吗? – summea 2013-04-09 17:20:00
我正在用JavaScript编写它。我知道它有一个JSON.parse()方法,但我总是在JSON的顶部看到“响应”,所以我将访问不同的信息,如(数据是responseText)“data.response.bookname”如果有多个结果,那么我会设置一个循环来增加它们。我只是不明白我会如何做到这一点。 – 2013-04-09 17:27:21
