iphone - 如何在 iphone 中上传参数以及图像和音频

Question

我是 iPhone 编程新手。任何人都可以告诉我我已经上传了图像和音频以及这些参数

输入参数:caption, user_id, mobile_tauky_id, blauky_id, image , audio (caption 和 blauky_id 是可选的)

使用下面的代码我可以上传image，同样我想先上传caption，user_id 表示一些整数值例如: 3, mobile_tauky_id 还有一些整数值 ex: 5, blauky_id 也有 ex: 2, 图像和音频。

我可以在哪里追加这些参数首先我想追加标题，然后是user_id，然后是mobile_tauky_id，blauky_id，之后我必须追加图像 和音频。任何人都可以告诉我如何在下面的代码中附加这些参数。我只能附加 image 但在此之前我想附加 caption、user_id、mobile_tauky_id。

NSString *urlString = @"http://182.73.152.59:82/php/tauky_services/codeigniter-restserver-master/index.php/api/uploadClass/uploadTauky/";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSLog(@"%@", request);

NSMutableData *body = [NSMutableData data];   

//Image
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"image\"; filename=\"%@\"\r\n",imageData] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
 [request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Response : %@",returnString);

if([returnString isEqualToString:@"Success ! The file has been uploaded"]) {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Image Saved Successfully" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
    [alert show];
}
NSLog(@"Finish");

您可以一个接一个地附加参数，例如:-

NSURL *dataURL=[[NSURL alloc]initWithString:[NSString stringWithFormat:@"http://182.73.152.59:82/php/tauky_services/codeigniter-restserver-master/index.php/api/uploadClass/uploadTauky/"]];

NSMutableURLRequest *dataRqst = [NSMutableURLRequest requestWithURL:dataURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:30.0];

[dataRqst setHTTPMethod:@"POST"];

NSString *stringBoundary = @"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo";
NSString *headerBoundary = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",stringBoundary];

[dataRqst addValue:headerBoundary forHTTPHeaderField:@"Content-Type"];

NSMutableData *postBody = [NSMutableData data];

// -------------------- ---- caption ---------------------------\\


[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Disposition: form-data; name=\"captionType\"\r\n\r\n"
                      dataUsingEncoding:NSUTF8StringEncoding]];

[postBody appendData:[caption  dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

//-------------------- ---- user_id -------------------- ------\

[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Disposition: form-data; name=\"UserIdType\"\r\n\r\n"
                      dataUsingEncoding:NSUTF8StringEncoding]];

[postBody appendData:[userId  dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

//-------------------- mobile_tauky_id -------------------- ------\

[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Disposition: form-data; name=\"mobile_tauky_idType\"\r\n\r\n"
                      dataUsingEncoding:NSUTF8StringEncoding]];

[postBody appendData:[mobile_tauky_id  dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

//-------------------- blauky_id -------------------- ------\

[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Disposition: form-data; name=\"blauky_idType\"\r\n\r\n"
                      dataUsingEncoding:NSUTF8StringEncoding]];

[postBody appendData:[blauky_id  dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];


 // media part

// -------------------- ---- Image Upload Status ---------------------------\

    [postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [postBody appendData:[@"Content-Disposition: form-data; name=\"type\"\r\n\r\n"
                          dataUsingEncoding:NSUTF8StringEncoding]];

    NSString *mediaType=@"Image";
    NSLog(@"type %@",mediaType);
    [postBody appendData:[mediaType dataUsingEncoding:NSUTF8StringEncoding]];
    [postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

    //pass MediaType file

    [postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [postBody appendData:[@"Content-Disposition: form-data; name=\"Data\"; filename=\"image.png\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [postBody appendData:[@"Content-Type: image/png\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [postBody appendData:[@"Content-Transfer-Encoding: binary\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    // get the image data from main bundle directly into NSData object
    NSData *imgData = UIImagePNGRepresentation(Your Image);
    // add it to body
    [postBody appendData:imgData];
    [postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

}

 // -------------------- ---- Audio Upload Status ---------------------------\

    [postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [postBody appendData:[@"Content-Disposition: form-data; name=\"type\"\r\n\r\n"
                          dataUsingEncoding:NSUTF8StringEncoding]];
    NSString *mediaType=@"Audio";
    NSLog(@"type %@",mediaType);
    [postBody appendData:[mediaType dataUsingEncoding:NSUTF8StringEncoding]];

    [postBody appendData:[@"Content-Transfer-Encoding: binary\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    NSString *url = [NSString stringWithFormat:@"%@/record.mp3", documentsDirectory];

    // get the audio data from main bundle directly into NSData object
    NSData *audioData;
    audioData = [[NSData alloc] initWithContentsOfFile:url];
    // add it to body
    [postBody appendData:audioData];
    [postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
}


// final boundary

[postBody appendData:[[NSString stringWithFormat:@"--%@--\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];

// add body to post

[dataRqst setHTTPBody:postBody];

NSHTTPURLResponse* response =[[NSHTTPURLResponse alloc] init];
NSError* error = [[NSError alloc] init] ;

//synchronous filling of data from HTTP POST response
NSData *responseData = [NSURLConnection sendSynchronousRequest:dataRqst returningResponse:&response error:&error];

//convert data into string
NSString *responseString = [[NSString alloc] initWithBytes:[responseData bytes] length:[responseData length] encoding:NSUTF8StringEncoding];

NSLog(@"Response String %@",responseString);
