Question

使用fetch时出错：

https://login.microsoftonline.com/common/oauth2/token 400 (Bad Request)

Failed to load https://login.microsoftonline.com/common/oauth2/token: 
No 'Access-Control-Allow-Origin' 
header is present on the requested resource. Origin 'http://localhost' is therefore 
not allowed access. The response had HTTP status code 400. If an opaque response serves
 your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Uncaught (in promise) TypeError: Failed to fetch

以下是现有的提取代码：

var formData = {
        "client_id": "",
        "grant_type": "",
        "resource": "https://analysis.windows.net/powerbi/api",
        "username": "",
        "password": "",
        "scope": "openid",
        "client_secret": "",
        "refresh_token": ""
    };


var options = {
    method: "post",
    headers: {
        "Content-Type": "application/x-www-form-urlencoded",
    },
    body: formData,
}

return fetch("https://login.microsoftonline.com/common/oauth2/token", options)
.then((response) => {
    if (response.ok) {
        return response.json();
    } else {
        throw new Error("Server response wasn't OK");
    }
})
.then((json) => {
    return json.token;
});

我想使用服务器端PHP请求来避免跨源问题。

PHP的版本是什么？

关于如何在PHP中使用cURL进行POST，有很多例子。我已经包含了我认为有点直接翻译你的javascript代码。

请注意，我没有对其进行测试，因此无法说明它是否与您的代码完全相同。此外，我不知道返回了什么json字符串，但我也包含了json_decode。但是从那以后你必须自己找出其余部分。

<?PHP
$url = 'https://login.microsoftonline.com/common/oauth2/token';

$fields = array(
    'client_id'     => '',
    'grant_type'    => '',
    'resource'      => urlencode('https://analysis.windows.net/powerbi/api'),
    'username'      => '',
    'password'      => '',
    'scope'         => 'openid',
    'client_secret' => '',
    'refresh_token' => ''
);

$headers = array(
    'Content-Type: application/x-www-form-urlencoded'
);

$fields_string = http_build_query($fields);

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

if ( $http_status == 200 ) {
 $json = json_decode(trim($result));
 echo "Token: ".$json->token."\n";
} else {
 echo "HTTP Status code: ".$http_status."\n";
 echo "Result: ".$result."\n";
}
?>

希望有所帮助

PS。懒惰很好，而且我喜欢copy-gt; pasta和其他人一样多，但你应该只是谷歌前面（字面意思是我做的）：）
