错误代码 500，在 Swift 中带有 Soap 请求

Question

我正在尝试执行一个调用加密函数并返回值的 soap 请求。当我对邮递员发出请求时，它有效。但是，我从邮递员那里得到了代码，但它返回错误代码 500。我认为问题可能出在 postData 中，我在双引号前添加 \。 法典：

let headers = [
"content-type": "text/xml",
"cache-control": "no-cache",
"postman-token": "4d266611-ea55-0c8a-7879-eac8bf387ed0"
]
let postData = NSData(data: "<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><Encrypt xmlns="http://tempuri.org/"><request>RequestIsValid29:01:2015 16:31</request> </Encrypt></soap:Body> </soap:Envelope>".data(using: String.Encoding.utf8)!)
let request = NSMutableURLRequest(url: NSURL(string: "http://mobileexam.veripark.com/mobileforeks/service.asmx")! 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)
}
})
dataTask.resume()

错误代码：

<NSHTTPURLResponse: 0x608000222300> { URL: http://mobileexam.veripark.com/mobileforeks/service.asmx } { status code: 500, headers {
"Cache-Control" = private;
Connection = "Keep-Alive";
"Content-Length" = 1802;
"Content-Type" = "application/soap+xml; charset=utf-8";
Date = "Mon, 28 Aug 2017 14:57:47 GMT";
Server = "Microsoft-IIS/7.5";
"X-AspNet-Version" = "4.0.30319";
"X-Powered-By" = "ASP.NET";
} })

正如我在问题中提到的。问题是字符串中的 xml 部分。我在" 之前添加 \，并在需要新行时添加 \r。下面的部分是 XML 的正确字符串版本。

"\rhttp://www.w3.org/2001/XMLSchema-instance\" xmlns：xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns：soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\r\

rhttp://tempuri.org/\">\rRequestIsValid29：01：2015 16：31 \r \r">

所以问题的最终工作代码是：

let poststring = "<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">r<soapenv:Header/> <soapenv:Body>r<tem:GetForexStocksandIndexesInfo> <tem:request>r<tem:IsIPAD>true</tem:IsIPAD>r<tem:DeviceID>test</tem:DeviceID>r<tem:DeviceType>ipad</tem:DeviceType>r<tem:RequestKey>(self.encrypt_code!)</tem:RequestKey>r<tem:RequestedSymbol>(name)</tem:RequestedSymbol>r<tem:Period>Month</tem:Period> </tem:request>r</tem:GetForexStocksandIndexesInfo> </soapenv:Body>r</soapenv:Envelope>"
let postData = NSData(data: poststring.data(using: String.Encoding.utf8)!)
let request = NSMutableURLRequest(url: NSURL(string: "http://mobileexam.veripark.com/mobileforeks/service.asmx")! as URL,
cachePolicy: .useProtocolCachePolicy,
timeoutInterval: 10.0)

你试过吗？

[lobj_Request setValue：@"gzip" forHTTPHeaderField：@"Accept-Encoding"];
