iOS upload voice to server instance

iOS upload voice to server, here is an introduction to use AFN to upload voice files to the service side.

Voice Turn NSData

If it is not nsdata, we should find a way to convert the voice file into NSData before uploading the server. First we get the NSData object for the voice file.

NSData *voicedata = [Message valueforkey:@ "Wavaudiodata"];

Upload Code

The code is as follows

Copy Code

Khosturl the main domain name for the app for the developer company, like http://xxx.yyy.cn Afhttprequestoperationmanager *manager = [[Afhttprequestoperationmanager alloc] Initwithbaseurl:[nsurl URLWithString : Khosturl]]; Manager.requestSerializer.timeoutInterval = 100; Nsmutabledictionary *paras = [[Nsmutabledictionary alloc]init]; [Paras SetValue:self.msgType forkey:@ "Msgtype"]; In the form of file, the key here is very important "accessory", this is the corresponding to the server, you must not write, be sure to see the interface document, or upload failure [Paras SetValue: (__bridge ID) ((__bridge FILE *) (VoiceData)) forkey:@ "accessory"]; [Paras Setvalue:[blluser Getpushtoken] forkey:@ "Senderpushtoken"]; [Paras SetValue:self.receiverPushToken forkey:@ "Receiverpushtoken"]; [Paras Setobject:[base getkey] forkey:@ "Ukey"]; afhttprequestoperation * operation = [manager post:kbllurl_chat_chat Parameters:paras constructingbodywithblock:^ (ID <AFMultipartFormData> formData) { NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; Formatter.dateformat = @ "YYYYMMDDHHMMSS"; NSString *str = [formatter stringfromdate:[nsdate date]]; filename here take the current timestamp Accessory is still the same as the service side, specifically look at your own interface document MimeType Choose @ "AMR/MP3/WMR", meaning to tell the server, I uploaded the file type is support three formats AMR, MP3 and WMR, here need to note Here I uploaded a amr format voice file, so if your voice files for other formats, must be the service end of the corresponding, such as the server to let you upload wav format voice, then you get AMR, how to do? Tell a joke, someone directly change the suffix, the service is not let me upload wav, directly to change. wav not on it! Someone really wants to do that. So here's to tell you, you're a man, you wear a woman's clothes, you're still a man. Even if you cut Tintin is not a woman, at most not male or female. The solution is to find a third-party library, your AMR voice converted to WAV, and then transferred to NSData and then upload it. NSString *filename = [NSString stringwithformat:@ "%@.amr", str]; [FormData appendpartwithfiledata:voicedata name:@ "accessory" filename:filename mimetype:@ "AMR/MP3/WMR"]; } success:^ (Afhttprequestoperation *operation, NSData * responseobject) { NSLog (@ "callback succeeded!"); Nserror * ERROR; Nsdictionary * dic = [nsjsonserialization jsonobjectwithdata:responseobject options:nsjsonreadingallowfragments Error :&error]; JSON resolves to get the dictionary returned by the storage server NSLog (@ "State ==%@", dic[@ "MSG"]); } failure:^ (Afhttprequestoperation *operation, Nserror *error) { Failed to connect to server NSLog (@ "send failed"); }]; Operation.responseserializer = [Afhttpresponseserializer serializer]; [Operation start];

Code can be directly copy, changed BaseURL and path, has been uploaded to key parameters. You can upload it successfully.
