我在RN中有以下代码:
postToServer(){
const requestBody = 'pin=1&status=false';
return fetch('https://192.168.10.200/writeStatus.php', {
method: 'POST',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
body: requestBody
}).then((response) => response.json())
.then((responseJson) => {
console.log(responseJson);
});
}
我也有以下php文件:
<?php
header('Access-Control-Allow-Origin: *');
$data = json_decode(file_get_contents('php://input'), true);
print_r($data);
?>
当我运行postToServer时,我收到:
可能未处理的Promise拒绝(id:0):TypeError:网络请求失败TypeError:XMLHttpRequest.xhr.onerror(http://192.168.10.248:19001/node_modules/expo/AppEntry.bundle?platform=android&dev=true&minify=false&hot=false&assetPlugin=P:\ sandbox \ MojDom1 \ node_modules \ expo \ tools \ hashAssetFiles:7854:16)的XMLHttpRequest.dispatchEvent网络请求失败(http://192.168.10.248:19001/node_modules/expo/AppEntry.bundle?platform=android&dev=true&minify=false&hot=false&assetPlugin=P:\ sandbox \ MojDom1 \ node_modules \ expo \ tools \ hashAssetFiles:12942:35)...(在这里留下一些行 - 我对链接有限制)在MessageQueue.callFunctionReturnFlushedQueue(http://192.168.10.248:19001/node_modules/expo/AppEntry.bundle?platform=android&dev=true&minify=false&hot=false&assetPlugin=P:\ sandbox \ MojDom1 \ node_modules \ expo) \ TOOLS \ hashAssetFiles:2122:12)
有人有什么建议吗?
为错误添加catch
方法:
postToServer(){
const requestBody = 'pin=1&status=false';
return fetch('https://192.168.10.200/writeStatus.php', {
method: 'POST',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
body: requestBody
}).then((response) => console.log(response))
}).catch(e => console.log(e));
