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
var details = {
'userName': 'test@gmail.com',
'password': 'Password!',
'grant_type': 'password'
};
var formBody = [];
for (var property in details) {
var encodedKey = encodeURIComponent(property);
var encodedValue = encodeURIComponent(details[property]);
formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");
fetch('http://identity.azurewebsites.net' + '/token', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: formBody
})
它对我很有帮助，而且没有任何错误

你可以使用FormData和URLSearchParams发布为application/x-www-form-urlencoded，示例如下:
如果你有一个表格:
<form>
<input name="username" type="text" />
<input name="password" type="password" />
<button type="submit">login</button>
</form>
您可以添加使用下面的JS来提交表单。
const form = document.querySelector("form");
form.addEventListener("submit", async () => {
const formData = new FormData(form);
try {
await fetch("https://example.com/login", {
method: "POST",
headers: {
"Content-Type": "application/x-www-form-urlencoded",
},
body: new URLSearchParams(formData),
});
} catch (err) {
console.log(err);
}
});
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)})
使用URLSearchParams
https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams
var data = new URLSearchParams();
data.append('userName', 'test@gmail.com');
data.append('password', 'Password');
data.append('grant_type', 'password');
只使用
import qs from "qs";
let data = {
'profileId': this.props.screenProps[0],
'accountId': this.props.screenProps[1],
'accessToken': this.props.screenProps[2],
'itemId': this.itemId
};
return axios.post(METHOD_WALL_GET, qs.stringify(data))
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);
}
});
