使用AFNetWorking 上传字符串，请求失败，Request failed: 请求太大

Question

我要把图片换成nsdata，然后再用base64encoding，把encoding后生成的字符串上传到
服务器，就出这个问题，
报错信息：err:Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: 请求太大 (413)"
我同事用的ASIHTTPRequest库就没问题，请问如何解决？
代码：

 UIImage *img = [self createThumbnailWithSourceImge:sourceImg andNewSize:sz];

       data  = UIImageJPEGRepresentation(img, 0.01);
        NSString *encodedSTR  = [data base64Encoding];
                NSString *currentUrl = @"/app/b/test";
        NSString *urlStr = [NSString stringWithFormat:@"%@%@?picStr=%@",BASEURL,currentUrl,encodedSTR];
        NSURL *url = [NSURL URLWithString:urlStr];
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
                 AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc]initWithRequest:request];
    op.responseSerializer = [AFJSONResponseSerializer serializer];
    [op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
//        NSLog(@"success:%@",responseObject);
        successBlock(responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        failureBlock(error);
    }];
    [op start];


     //   [manager POST:urlStr parameters:nil
     //         success:^(AFHTTPRequestOperation *operation, id responseObject) {
        //          NSLog(@"success:%@",responseObject);
         //     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         //         NSLog(@"err:%@",error);
         //     }];

使用AFNetworking 2.0 请求数据时出现错误 Request failed: unacceptable content-type: text/html 解决方法

添加一行

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
即可

整个代码为：

复制代码
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
NSDictionary *parameters = @{@"foo":@"bar"};
[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error:%@",error);
}];
