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{{ 1}}是可选的）

使用以下代码，我可以上传blauky_id，同样我想先上传image，caption表示一些整数值，例如：user_id，3一些整数值ex：mobile_tauky_id，5也是例如：blauky_id，2和image。

我可以在哪里添加这些参数首先我要添加标题，然后是audio，然后是user_id，mobile_tauky_id，之后我必须附加blauky_id和{{1 }}。任何机构都可以告诉我如何在下面的代码中附加这些参数。我只能追加image，但在此之前我想要附加标题，audio，image。

user_id

您可以逐个追加参数，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:[@"\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=\"myVoice.mp3\"\r\n" 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);
