我想使用AFNetwork发布表单数据。我正在使用这段代码来实现这一点：
// Create service request url
NSString *urlString = [NSString stringWithFormat:@"%@%@", kBaseURL, webServiceAPIName];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setValue:@"myUser" forHTTPHeaderField:@"X-User-Agent"];
[manager.requestSerializer setValue:@"multipart/form-data" forHTTPHeaderField:@"Content-Type"];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
// Set calling keys
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:@"5341" forKey:@"Id"];
[dict setObject:@"f1" forKey:@"refDataId"];
[dict setObject:@"f1" forKey:@"customRefDataId"];
[dict setObject:@"587" forKey:@"cost"];
[manager POST:urlString parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:UIImagePNGRepresentation(files[0]) name:@"ImageName" fileName:@"file1" mimeType:@"image/png"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"upload successful");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error image upload");
}];
在等待一段时间后，这个程序块执行后，它进入失败部分。记录:< code >“错误图像上传”。没有任何错误。
我在< code>POSTMAN API CLIENT中尝试了我的API，它运行良好。我能够发送数据并得到回复。
运行这个程序块后，我无法运行任何其他API调用，我必须停止我的应用程序，然后再次运行以运行任何其他API调用。
这段代码有什么问题，为什么我不能上传任何表单数据，为什么它会阻止我的任何其他API调用
试试下面的代码：
-(void) uploadImage {
NSString *imagePath = [[NSUserDefaults standardUserDefaults] objectForKey:@"userimage"];
NSString * urlString = [stagingURL stringByReplacingOccurrencesOfString:@"user/" withString:@""];
NSString * uploadURL = @"Your URL where image to be uploaded";
NSLog(@"uploadImageURL: %@", uploadURL);
NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithData:[NSData dataWithContentsOfFile:imagePath]], 0.5);
NSString *queryStringss = [NSString stringWithFormat:@"%@",uploadURL];
queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer=[AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];
[manager POST:queryStringss parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:@"file" fileName:@"file" mimeType:@"image/jpeg"];
}
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
NSLog(@"Error: %@ ***** %@", operation.responseString, error);
}];}
