AFHTTPSessionManager将主体添加到POST

Question

我也需要向我的服务器发帖子请求.

使用AFHTTPRequestOperation非常简单,只需使用:

[request setHTTPBody: [requestBody dataUsingEncoding:NSUTF8StringEncoding]];

但是,我找不到任何使用AFHTTPSessionManager使用相同方法的示例.

使用方法:

[self POST:@"extraLink" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

} success:^(NSURLSessionDataTask *task, id responseObject) {

} failure:^(NSURLSessionDataTask *task, NSError *error) {

}];

我如何将主体添加到"AFMultipartFormData"？

谢谢你的推荐

从AFNetworking 主页获取,要创建multipart/form-data请求,请致电appendPartWithFileURL:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileURL:filePath name:@"image" error:nil];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

但是AFHTTPRequestOperationManager被弃用了.所以,相反,使用AFHTTPSessionManager,对于其中的语法POST与constructingBodyWithBlock非常相似:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
NSURL *filePath = [NSURL fileURLWithPath:@"file://path/to/image.png"];
[manager POST:@"http://example.com/resources.json" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileURL:filePath name:@"image" error:nil];
} progress:nil success:^(NSURLSessionDataTask *operation, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(NSURLSessionDataTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

或者,如果您想发布表单请求foo=bar&key=value&...(即application/x-www-form-urlencoded请求),您可以执行以下操作:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *parameters = @{@"foo": @"bar", @"key": @"value"};
[manager POST:@"http://example.com/resources.json" parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
    NSLog(@"Success: %@", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
    NSLog(@"Error: %@", error);
}];

尝试其他方式。

我正在将图像转换为数据格式imageData。

NSData *imageData=nil;
imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"yourimageName"],0.2);
NSMutableDictionary *dict=[NSMutableDictionary new];
[dict setObject:@"user1" forKey:@"param_name1"];
[dict setObject:@"User2" forKey:@"param_name2"];

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] init];

[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
manager.responseSerializer = [AFJSONResponseSerializer
                              serializerWithReadingOptions:NSJSONReadingAllowFragments];
[manager POST:@"API NAME" parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

 if(imageData)
 {
     [formData appendPartWithFileData:imageData  name:@"param_name" fileName:@"filename.jpg" mimeType:@"image/jpeg"];
 }
 } progress:^(NSProgress * _Nonnull uploadProgress)
 {
     NSLog(@"%@",uploadProgress);
 } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
     NSLog(@"%@",responseObject);

 } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
     NSLog(@"%@",error);

 }];
