在Javascript中将JSON对象保存到WCF REST服务 [英] Saving JSON object to WCF REST SERVICES in Javascript
本文介绍了在Javascript中将JSON对象保存到WCF REST服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在创建一个chrome扩展，因为我想在javascript中将JSON对象发送到WFC REST服务（.svc）。我的javascript代码低于
var myRequest = new XMLHttpRequest（）;
myRequest.onreadystatechange = function（）{
if （myRequest.readyState == 4 && myRequest.status == 200 ）{
console.log（ ' 发送到服务器：' + dataString + ' ）;
window.localStorage.removeItem（dataString）;
}
else if （myRequest.readyState == 4 && myRequest.status！= 200 ）{
console.log（' 服务器请求无法完成'）;
saveDataLocally（dataString）;
}
}
myRequest.open（ POST， http：// localhost：8221 / Service1.svc / SaveData，真）;
myRequest.setRequestHeader（ Content-Type， application / json）;
myRequest.send（dataString）;
dataString是一个JSON对象
dataString ={firstName：suresh，lastName：kumar}
我得到错误
POST http：// localhost：8221 / Service1.svc / SaveData 415（不支持的媒体类型）

I am creating a chrome extension , in that i want to send a JSON object to WFC REST Services(.svc) in javascript. My javascript code below
var myRequest = new XMLHttpRequest();
myRequest.onreadystatechange=function() {
if (myRequest.readyState == 4 && myRequest.status == 200) {
console.log('Sent to server: ' + dataString + '');
window.localStorage.removeItem(dataString);
}
else if (myRequest.readyState == 4 && myRequest.status != 200) {
console.log('Server request could not be completed');
saveDataLocally(dataString);
}
}
myRequest.open("POST","http://localhost:8221/Service1.svc/SaveData",true);
myRequest.setRequestHeader("Content-Type","application/json");
myRequest.send(dataString);
