已有代码：
var decodedJsonDict:JSON?
let fullNsurl: NSURL = NSURL(string: url)!
print("fullNsurl=\(fullNsurl)")
let urlReq: NSURLRequest = NSURLRequest(URL: fullNsurl)
print("urlReq=\(urlReq)")
do {
let response: AutoreleasingUnsafeMutablePointer<NSURLResponse? >= nil
let respJsonData: NSData = try NSURLConnection.sendSynchronousRequest(urlReq, returningResponse: response)
//print("response=\(response)") //response=0x0000000000000000
//print("respJsonData=\(respJsonData)")
decodedJsonDict = JSON(data: respJsonData)
print("decodedJsonDict=\(decodedJsonDict)")
}catch let httpGetErr {
print("httpGetErr=\(httpGetErr)")
decodedJsonDict = nil
}现在需要，添加header
Accept:application/json
Content-Type:application/json
搜：
swift NSURLConnection add header
参考：
var decodedJsonDict:JSON?
let fullNsurl: NSURL = NSURL(string: url)!
print("fullNsurl=\(fullNsurl)")
// let urlReq: NSURLRequest = NSURLRequest(URL: fullNsurl)
let mutableUrlReq:NSMutableURLRequest = NSMutableURLRequest(URL: fullNsurl)
//add header
// mutableUrlReq.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: nil, error: &err)
mutableUrlReq.addValue("application/json", forHTTPHeaderField: "Content-Type")
mutableUrlReq.addValue("application/json", forHTTPHeaderField: "Accept")
do {
let response: AutoreleasingUnsafeMutablePointer<NSURLResponse? >= nil
let respJsonData: NSData = try NSURLConnection.sendSynchronousRequest(mutableUrlReq, returningResponse: response)
decodedJsonDict = JSON(data: respJsonData)
print("decodedJsonDict=\(decodedJsonDict)")
}catch let httpGetErr {
print("httpGetErr=\(httpGetErr)")
decodedJsonDict = nil
}即可。
