在SWIFT中上传具有其他参数的图像 [英] Uploading image with other parameters in SWIFT
问题描述
我想使用SWIFT使用其他参数将图像上传到服务器,并且服务器端脚本在PHP中.我将请求发布到 http://www.23look.com/merchant/verify 接受以下参数:
I want to upload image to server with other parameters using SWIFT and the server side script is in PHP. I'm posting the request to http://www.23look.com/merchant/verify which accepts following parameters:
mer_name-字符串
mer_name - String
mer_tel-字符串
mer_tel - String
mer_address-字符串
mer_address - string
lng-字符串
lat-字符串
mer_licence-文件类型
mer_licence - file type
令牌-字符串
mer_type-字符串
mer_type - string
每当我发出HTTP发布请求时,它总是在响应中返回0值,这意味着系统错误".也许我做错了什么,有人可以帮我看看我的代码吗?
Whenever I make HTTP post request, it always returns 0 value in response, which means "System Error". Maybe there's something wrong I'm doing, can someone please help me see my code?
func uploadImage()
{
let postPictureUrl = NSURL(string: "http://www.23look.com/merchant/verify")
let request = NSMutableURLRequest(URL: postPictureUrl!)
request.HTTPMethod="POST"
let param=[
"mer_name" : shopNameUITF.text!,
"mer_tel" : shopTelephoneUITF.text!,
"mer_address" : shopAddressUITF.text!,
"lat" : "39.6892",
"lng" : "115.9239",
"token": KeychainWrapper.stringForKey("tokenValue")!,
"mer_type": "smalll"
]
let abc = KeychainWrapper.stringForKey("tokenValue")!
let boundary = generateBoundaryString()
request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
let imageData = UIImageJPEGRepresentation(myImageView.image!, 0.1)
if imageData==nil { print("image data is nil"); return }
request.HTTPBody = createBodyWithParameters(param, filePathKey: "mer_license", imageDataKey: imageData!, boundary: boundary)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}
//You can print out response object
print("***** response = \(response)")
// Print out reponse body
let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("**** response data = \(responseString!)")
do {
let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary
dispatch_async(dispatch_get_main_queue(), {
print(NSString(data: data!, encoding:NSUTF8StringEncoding)!)
print(json)
})
} catch let err {
print(err)
}
}
task.resume()
}
func generateBoundaryString() -> String {
return "Boundary-\(NSUUID().UUIDString)"
}
func createBodyWithParameters(parameters:[String:String]?, filePathKey: String?, imageDataKey:NSData, boundary: String) -> NSData {
var body=NSMutableData()
if parameters != nil {
for(key, value) in parameters! {
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
body.appendString("\(value)\r\n")
}
}
let filename = "user-profile.jpg"
let mimetype = "image/jpg"
body.appendString("--\(boundary)\r\n")
body.appendString("Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n")
body.appendString("Content Type: \(mimetype)\r\n\r\n")
body.appendData(imageDataKey)
body.appendString("\r\n")
body.appendString("--\(boundary)--\r\n")
return body
} extension NSMutableData {
func appendString(string: String) {
let data = string.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
appendData(data!)
}
推荐答案
如果使用appendData
而不是appendString
进行操作怎么办:
what if you do it with an appendData
instead of appendString
:
let body = NSMutableData()
let tempData = NSMutableData()
for (key, value) in parameters {
tempData.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
tempData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
tempData.appendData("\(value!)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
// etc etc
}
body.appendData(tempData)
request.setValue("\(body.length)", forHTTPHeaderField: "Content-Length")
request.HTTPBody = body
