我尝试使用特定的VIN发布到此API以获取make，model，color options等...当我运行代码时，我在XCode控制台中返回以下数据：
responseString = Optional(" { \"decoder_messages\" : { \"service_provider\" : \"DataOne Software, Inc.\", \"decoder_version\" : \"7.0.1\", \"decoder_errors\" : [ { \"error_code\" : \"IQ\", \"error_message\" : \"Invalid query. Query must be properly formatted JSON.\" } ] }, \"query_responses\" : { } } ")
我猜测错误可能在我的getJSONInput（）函数中，但我尝试了许多不同的方法，结果相同。感谢您的帮助，我对此感到非常难过，并阅读了各种文档并使用示例代码。我也曾尝试使用Alamofire，但是将postString作为参数传递出来，所以我想我会尝试这种方法。
@IBAction func postButtonPressed(_ sender: AnyObject) {
getJSONInput()
postJSON()
}
func postJSON(){
var request = URLRequest(url: URL(string: url)!)
request.httpMethod = "POST"
let postString = "client_id=xxx&authorization_code=xxx&decoder_query=\(JSONInput)"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print("error=(error)")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(response)")
}
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(responseString)")
}
task.resume()
}
func getJSONInput() {
JSONInput = "{" +
