iOS UrlSession.shared.dataTask移除utf-8“ +”字符并将其替换为“ " [英] iOS UrlSession.shared.dataTask removes utf-8 "+" character and replaces it with " "
问题描述
我正在使用x-www-form-endoded数据创建对API的登录调用。我在邮递员中创建了一个POST,并收到200条回复。我使用Postman的导出功能来生成Android的OKHTTP代码和iOS的NSURL代码。 Android代码工作正常,但iOS代码收到401响应。我使用Charles Web调试代理来查看有效负载实际发送的内容。对于android,用户名正确表示为 username=james+jypsee@jypsee.com,但在iOS中,用户名正确显示为 username = james jypsee@jypsee.com。我的iOS代码如下:
I'm creating a login call to an API using x-www-form-endoded data. I created a POST in Postman and received a 200 response. I used Postman's export function to generate the OKHTTP code for Android and NSURL code for iOS. The Android code works fine, but the iOS code receives a 401 response. I used Charles web debugging proxy to look at what was actually being sent for the payload. For android the username is correctly represented as "username=james+jypsee@jypsee.com" but in iOS it comes out as "username=james jypsee@jypsee.com". My iOS code is below:
let headers = [
"accept": "application/json",
"cache-control": "no-cache",
"content-type": "application/x-www-form-urlencoded"
]
let postData = NSMutableData(data: "username=james+jypsee@jypsee.com".data(using: .utf8)!)
postData.append("&password=redacted".data(using: .utf8)!)
postData.append("&grant_type=password".data(using: .utf8)!)
postData.append("&client_id=redacted".data(using: .utf8)!)
postData.append("&client_secret=redacted".data(using: .utf8)!)
let request = NSMutableURLRequest(url: NSURL(string: "https://redacted.com/api/oauth2/token/")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)
request.httpMethod = "POST"
request.allHTTPHeaderFields = headers
request.httpBody = postData as Data
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if (error != nil) {
print(error)
} else {
let httpResponse = response as? HTTPURLResponse
print(httpResponse)
}
})
何时我逐步执行了iOS代码,NSMutableData和Data对象都正确地将用户名显示为 username=james+jypsee@jypsee.com,只是将URLSession.shared作为潜在的错误原因。但是我无法进入URLSession.shared.dataTask(),因为它是私有方法。感谢您的帮助。
When I stepped through the iOS code both the NSMutableData and Data objects correctly displayed the username as "username=james+jypsee@jypsee.com", just leaving the URLSession.shared as the potential cause of error. But I can't step into URLSession.shared.dataTask() because its a private method. Any help is appreciated.
推荐答案
+字符编码存在一些问题。您可以尝试以下操作:
There is some issue with encoding of "+" characters. You can try this instead:
let postData = NSMutableData(data: "username=james%2Bjypsee@jypsee.com".data(using: .utf8)!)
