我有一些参数，我想POST表单编码到我的服务器:
{
'userName': 'test@gmail.com',
'password': 'Password!',
'grant_type': 'password'
}
我像这样发送我的请求(目前没有参数)
var obj = {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
},
};
fetch('https://example.com/login', obj)
.then(function(res) {
// Do stuff with result
});
如何在请求中包含表单编码的参数?
当前回答
不需要使用jQuery、querystring或手动组装有效负载。URLSearchParams是一种方法，这里是一个最简洁的答案与完整的请求示例:
fetch('https://example.com/login', {
method: 'POST',
body: new URLSearchParams({
param: 'Some value',
anotherParam: 'Another value'
})
})
.then(response => {
// Do stuff with the response
});
同样的技术使用async / await。
const login = async () => {
const response = await fetch('https://example.com/login', {
method: 'POST',
body: new URLSearchParams({
param: 'Some value',
anotherParam: 'Another value'
})
})
// Do stuff with the response
}
是的，您可以使用Axios或任何其他HTTP客户端库来代替本机获取。

在一个简单的函数中包装取回
async function post_www_url_encdoded(url, data) {
const body = new URLSearchParams();
for (let key in data) {
body.append(key, data[key]);
}
return await fetch(url, { method: "POST", body });
}
const response = await post_www_url_encdoded("https://example.com/login", {
"name":"ali",
"password": "1234"});
if (response.ok){ console.log("posted!"); }
只需将主体设置为如下所示
var reqBody = "username="+username+"&password="+password+"&grant_type=password";
then
fetch('url', {
method: 'POST',
headers: {
//'Authorization': 'Bearer token',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
body: reqBody
}).then((response) => response.json())
.then((responseData) => {
console.log(JSON.stringify(responseData));
}).catch(err=>{console.log(err)})
只是这样做，UrlSearchParams做的把戏 这是我的代码，如果能帮到别人的话
import 'url-search-params-polyfill';
const userLogsInOptions = (username, password) => {
// const formData = new FormData();
const formData = new URLSearchParams();
formData.append('grant_type', 'password');
formData.append('client_id', 'XXXX-app');
formData.append('username', username);
formData.append('password', password);
return (
{
method: 'POST',
headers: {
// "Content-Type": "application/json; charset=utf-8",
"Content-Type": "application/x-www-form-urlencoded",
},
body: formData.toString(),
json: true,
}
);
};
const getUserUnlockToken = async (username, password) => {
const userLoginUri = `${scheme}://${host}/auth/realms/${realm}/protocol/openid-connect/token`;
const response = await fetch(
userLoginUri,
userLogsInOptions(username, password),
);
const responseJson = await response.json();
console.log('acces_token ', responseJson.access_token);
if (responseJson.error) {
console.error('error ', responseJson.error);
}
console.log('json ', responseJson);
return responseJson.access_token;
};
*/ import this statement */
import qs from 'querystring'
fetch("*your url*", {
method: 'POST',
headers: {'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'},
body: qs.stringify({
username: "akshita",
password: "123456",
})
}).then((response) => response.json())
.then((responseData) => {
alert(JSON.stringify(responseData))
})
在使用npm i querystring后，保存它的工作很好。
您可以使用react-native-easy-app，更容易发送http请求和制定拦截请求。
import { XHttp } from 'react-native-easy-app';
* Synchronous request
const params = {name:'rufeng',age:20}
const response = await XHttp().url(url).param(params).formEncoded().execute('GET');
const {success, json, message, status} = response;
* Asynchronous requests
XHttp().url(url).param(params).formEncoded().get((success, json, message, status)=>{
if (success){
this.setState({content: JSON.stringify(json)});
} else {
showToast(msg);
}
});
