Weex网络请求
Weex网络请求，使用其内置模块Stream.
Stream API
fetch(options, callback[,progressCallback])
发起网络请求
注意点：
1.body参数仅支持 string 类型的参数，请勿直接传递 JSON，必须先将其转为字符串。
2.body参数不支持Get请求，如果使用Get请求，需要在url上传参。
封装一个自己的Stream模块
封装成request.js代码：
const stream = weex.requireModule("stream");
const modal = weex.requireModule("modal");
const requestMethod = ["post", "get"];
const request = {};
requestMethod.forEach(method => {
request[method] = (url = "", params = "", config = {}) => {
let requestUrl = url;
let headers = Object.assign(
{}, { "Content-Type": "application/x-www-form-urlencoded" }, config.headers
);
if (method === "get") {
requestUrl = `${url}?${params}`;
params = "";
}
return new Promise((resolve, reject) => {
stream.fetch({
method,
url: requestUrl,
type: "json",
headers,
body: params,
timeout: 8000,
}, function (res) {
if (res.ok) {
let data = res.data;
if (data && data.control.error == 0) {
resolve(data.data);
} else {
modal.confirm({
message: data.control.msg,
duration: 0.3
});
}
return;
}
reject({
status: res.status,
msg: res.statusText
});
modal.confirm({
message: res.statusText,
duration: 0.3
});
});
});}
});
module.exports = request;
使用封装后的stream模块
let request = require("./request.js");
request.post(
'http://localhost:9090/wap/open/indexHome',userName=${this.userName}&age=${this.age}
).then((res)=>{
this.userName = res.userName;
this.age = res.age;
},(e)=>{
console.log(e);
});
Express接收请求
let express = require('express');
let bodyParser = require('body-parser');
let app = module.exports = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.post('/wap/open/indexHome',function(req,res){
let {userName,age} = req.body;
res.json({
control:{
error: 0
},
data: {
userName,
age
}});
});
app.listen(9090,function(){
console.log("Server listening on port :'9090'");
});
