我试图在 Brain Tree 中生成一个 token ，由于某种原因，它生成整个 html，这导致 token 无效，如何解决这个问题。这是我当前的功能
func brainTree() {
let clientTokenURL = NSURL(string: "http://mywesitelinkhere.com/braintree_php_api/public_html/index.php/client_token")!
let clientTokenRequest = NSMutableURLRequest(URL: clientTokenURL)
clientTokenRequest.setValue("text/plain", forHTTPHeaderField: "Accept")
NSURLSession.sharedSession().dataTaskWithRequest(clientTokenRequest) { (data, response, error) -> Void in
print("data start- \(data) -data end")
print("response start- \(response) -response end")
print("Error is \(error?.localizedDescription)")
let clientToken = String(data: data!, encoding: NSUTF8StringEncoding)!
print("token is\(clientToken) token end")
self.braintreeClient = BTAPIClient(authorization: clientToken)
// As an example, you may wish to present our Drop-in UI at this point.
// Continue to the next section to learn more...
}.resume()
}
这是正在打印的 token

最佳答案
全面披露:我在 Braintree 工作。如果您还有任何疑问，请随时联系support .
问题在于您的服务器端代码，而不是 swift 中的任何内容。问题是您的网站只需要提供 token 而不是 HTML。您可以在 Mac/*nix 系统上使用 curl 进行测试:
curl http://mywesitelinkhere.com/braintree_php_api/public_html/index.php/client_token
如果此命令返回的不仅仅是客户端 token 字符串，那么您需要修复您的服务器。 Braintree getting started guide's client token generation lines确实是您所需要的:
<?php
Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('use_your_merchant_id');
Braintree_Configuration::publicKey('use_your_public_key');
Braintree_Configuration::privateKey('use_your_private_key');
echo($clientToken = Braintree_ClientToken::generate());
?>
查看您的服务器代码，并从该 url 中删除除打印此字符串之外的所有内容。
关于swift - Braintree Swift 继续在生成的 token 中打印 html，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38023935/
