ASIHttpRequest的子类ASIFormDataRequest 上传音频文件到服务器

#define KURLHead_2  @"http://192.168.0.188/upload/api/index.php?m=amuseUploadAudio"

NSString *uploadPath = [[NSBundle mainBundle] pathForResource:@"9ff977fed42b3de4aca40356be942ad9" ofType:@"spx"];NSURL *url = [[NSURLalloc]initWithString:KURLHead_2];ASIFormDataRequest *request = [ASIFormDataRequestrequestWithURL:url];  [request setFile:uploadPath forKey:@"audio"];   //uploadPath：上传路径； audio:上传参数名，一定要跟接口给出的参数名一样；[requestsetDelegate:self];[requeststartAsynchronous];

使用ASIFormDataRequest POST表单

通常数据是以’application/x-www-form-urlencoded’格式发送的，如果上传了二进制数据或者文件，那么格式将自动变为‘multipart/form-data’ 。

文件中的数据是需要时才从磁盘加载，所以只要web server能处理，那么上传大文件是没有问题的。

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; [request setPostValue:@"Ben" forKey:@"first_name"]; [request setPostValue:@"Copsey" forKey:@"last_name"]; [request setFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photo"];

数据的mime头是自动判定的，但是如果你想自定义mime头，那么这样：

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; // Upload a file on disk [request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"]; // Upload an NSData instance [request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];

你可以使用addPostValue方法来发送相同name的多个数据（梦维：服务端会以数组方式呈现）：

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; [request addPostValue:@"Ben" forKey:@"names"]; [request addPostValue:@"George" forKey:@"names"]; [request addFile:@"/Users/ben/Desktop/ben.jpg" forKey:@"photos"]; [request addData:imageData withFileName:@"george.jpg" andContentType:@"image/jpeg" forKey:@"photos"];

PUT请求、自定义POST请求

如果你想发送PUT请求，或者你想自定义POST请求，使用appendPostData: 或者 appendPostDataFromFile:

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request appendPostData:[@"This is my data" dataUsingEncoding:NSUTF8StringEncoding]]; // Default becomes POST when you use appendPostData: / appendPostDataFromFile: / setPostBody: [request setRequestMethod:@"PUT"];
