我将图片从图库转换为base64，然后将其上传到＆＃39; webServices.asmx＆＃39;。 图像在服务器上损坏，还是我的错？我不知道。 我试着将字符串放入：＆＃39; http://www.freeformatter.com/base64-encoder.html＆＃39;并解码字符串并获得正确的图像。
我的代码：
// HTTP POST
NSURL *url = [NSURL URLWithString:@""];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
[httpClient setDefaultHeader:@"Content-Type" value:@"application/x-www-form-urlencoded"];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
[NSString stringWithFormat:@"%d", userID], @"userID",
self.imageBase64, @"file",
nil];
[httpClient postPath:@"http://www....../webServices.asmx/saveImageIOS" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"\nResponse XML: \n%@", responseString);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error.localizedDescription);
}];
样本base64字符串（转换后的图像）：
