This time I will bring you apicloud to implement AJAX requests (with code). What are the precautions for apicloud to implement AJAX requests? Here are practical cases, let’s take a look.
get request code:
api.ajax({
url:'http://m.weather.com.cn/data/101010100.html' //天气预报网站的WebService接口
},function(ret,err){
if (ret) {
api.alert({msg:JSON.stringify(ret)});
} else {
api.alert({msg:JSON.stringify(err)});
};
});
POST request-Form form submission:
api.ajax({
url: 'http://www.xxx.com/path/form',
method: 'post',
dataType: 'text', //该参数若不传，则默认为json
data: {
values:{name: 'devlp', password: '123456'} //键值对
}
},function(ret,err){
if (ret) {
api.alert({msg:JSON.stringify(ret)});
} else {
api.alert({msg:JSON.stringify(err)});
};
});
POST request-single/multiple files, file group upload:
api.ajax({
url: 'http://www.xxx.com/path/upLoad',
method: 'post',
data: {
files:{myfile: 'filepath'}
// filepath来自ios或者Android的文件系统中的任意文件。可设置多个文件，甚至是文件数组，如files:{myfile: 'filepath', myfile1: 'filepath1'}或者files:{'myfile[]': ['filepath', 'filepath1']}等
}
},function(ret,err){
if (ret) {
api.alert({msg:JSON.stringify(ret)});
} else {
api.alert({msg:JSON.stringify(err)});
};
});
POST request - submit binary stream:
api.ajax({
url: 'http://www.xxx.com/path/body',
method: 'post',
data: {
body:'textbits'
}
},function(ret,err){
if (ret) {
api.alert({msg:JSON.stringify(ret)});
} else {
api.alert({msg:JSON.stringify(err)});
};
});
POST request - submit file stream:
api.ajax({
url: 'http://www.xxx.com/path/body',
method: 'post',
data: {
stream:'filepath'
// filepath来自ios或者Android的文件系统中的任意文件
}
},function(ret,err){
if (ret) {
api.alert({msg:JSON.stringify(ret)});
} else {
api.alert({msg:JSON.stringify(err)});
};
});
POST Request-Multipart-Data, file and text fields submitted together:
api.ajax({
url: 'http://www.xxx.com/path/multipart',
method: 'post',
data: {
values:{name: 'devlp', password: '123456'},
files:{file: 'fs://test.png'}
}
},function(ret,err){
if (ret) {
api.alert({msg:JSON.stringify(ret)});
} else {
api.alert({msg:JSON.stringify(err)});
};
});
POST Request-Display Upload progress:
api.ajax({
url: 'http://www.xxx.com/path/multipart',
method: 'post',
report: true,
data: {
values:{name: 'devlp', password: '123456'},
files:{file: 'fs://test.png'}
}
},function(ret,err){
if(ret){
if(0 == ret.status){
//loading('进度：' + ret.progress);
}else{
api.alert({msg:'上传成功：\n' + JSON.stringify(ret)});
}
}else{
api.alert({msg:JSON.stringify(err)});
}
});
[End API uses api.ajax to read interface data]
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="maximum-scale=1.0,minimum-scale=1.0,user-scalable=0,width=device-width,initial-scale=1.0"/>
<title>test</title>
</head>
<body>
<button onclick="showPersonInfo()">点我获取数据</button>
</body>
<script type="text/javascript" src="../script/api.js"></script>
<script>
function showPersonInfo(){
api.showProgress();//显示加载进度框
//使用api.ajax请求数据，具体使用方法和参数请看官方文档，这里使用get方法演示
api.ajax({
url:'http://192.168.0.10/get.php',//如果地址访问不到会请求出错，请填写自己的接口地址
method:'get',
cache:'false',
timeout:30,
dataTpye:'json',
},function(ret,err){
api.hideProgress();//隐藏加载进度框
if(ret){
for(var i=0;i<ret.length;i++){
var html='<br>'+'ID：'+ret[i].id+'<br>'+'姓名：'+ret[i].name+'<br>'+'性别:'+ret[i].sex+'<br>'+'年龄'+ret[i].age;
document.write(html);
}
}else{
api.alert({msg:('错误码：'+err.code+'；错误信息：'+err.msg+'网络状态码：'+err.statusCode)});
}
});
}
</script>
</html>
