objective-c - 如何在 iOS 中使用 Reskit 上传文件

Question

我将如何使用 Restkit 上传音频文件？我查看了文档，似乎找不到有关上传文件的任何信息。谢谢你的帮助。

Answer 1

本文解释了如何：http: //mobile.tutsplus.com/tutorials/iphone/advanced-restkit-development_iphone-sdk/

摘抄：

NSString* myFilePath = @"/some/path/to/picture.gif";
RKParams* params = [RKParams params];

// Set some simple values -- just like we would with NSDictionary
[params setValue:@"Blake" forParam:@"name"];
[params setValue:@"blake@restkit.org" forParam:@"email"];

// Create an Attachment
RKParamsAttachment* attachment = [params setFile:myFilePath forParam:@"image1"];
attachment.MIMEType = @"image/gif";
attachment.fileName = @"picture.gif";

// Attach an Image from the App Bundle
UIImage* image = [UIImage imageNamed:@"another_image.png"];
NSData* imageData = UIImagePNGRepresentation(image);
[params setData:imageData MIMEType:@"image/png" forParam:@"image2"];

// Let's examine the RKRequestSerializable info...
NSLog(@"RKParams HTTPHeaderValueForContentType = %@", [params HTTPHeaderValueForContentType]);
NSLog(@"RKParams HTTPHeaderValueForContentLength = %d", [params HTTPHeaderValueForContentLength]);

// Send a Request!
[[RKClient sharedClient] post:@"/uploadImages" params:params delegate:self];

享受！

对于 Restkit 0.20，创建附件时会自动检测 MIME 类型。所以你不需要打电话

attachment.MIMEType

在构建参数时：

[params setData:imageData MIMEType:attachment.MIMEType forParam:@"image2"];
