我正在更新使用ASIHTTPRequest与AFNetworking的旧应用程序代码.在我的情况下,我正在向API发送一个数据库,这些数据是不同的类型：图像和其他.
以下是我现在采用的代码,实现API客户端,请求共享实例,准备params字典并将其发送到远程API：
NSMutableDictionary *params = [NSMutableDictionary dictionary]; [params setValue:@"Some value" forKey:aKey]; [[APIClient sharedInstance] postPath:@"/post" parameters:params success:^(AFHTTPRequestOperation *operation,id responSEObject) { //some logic } failure:^(AFHTTPRequestOperation *operation,NSError *error) { //handle error }];
当我想要添加一个图像到params字典会是什么情况？
使用ASIHTTPRequest,我曾经做过以下事情：
NSData *imgData = UIImagePNGRepresentation(anImage);
NSString *newStr = [anImageName stringByReplacingOccurrencesOfString:@"/"
withString:@"_"];
[request addData:imgData
withFileName:[NSString stringWithFormat:@"%@.png",newStr]
andContentType:@"image/png"
forKey:anOtherKey];
我挖掘了AFNetworking文档,发现他们将图像附加在NSMutableRequest中,如下所示：
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"avatar.jpg"],0.5);
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:@"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:imageData name:@"avatar" fileName:@"avatar.jpg" mimeType:@"image/jpeg"];
}];
我应该如何混合在一起整合我的图像数据到APIClient请求？ Thanx提前.
解决方法
我已经使用相同的AFNetworking上传图像与一些参数.这段代码对我来说很好.可能会有所帮助
NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image,1.0);//(uploadedImgView.image);
if (imageToUpload)
{
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter,@"keyName",nil];
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://------"]];
NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData: imageToUpload name:@"image" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation,id responSEObject)
{
NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responSEObject options:kNilOptions error:nil];
//NSLog(@"response: %@",jsons);
}
failure:^(AFHTTPRequestOperation *operation,NSError *error)
{
if([operation.response statusCode] == 403)
{
//NSLog(@"Upload Failed");
return;
}
//NSLog(@"error: %@",[operation error]);
}];
[operation start];
}
祝你好运 ！！
