使用AFNetWorking 上传字符串，提示：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);
         //     }];

图片转换成 NSData 之后就不用再转 String 了，直接上传就行了。

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString: BASEURL]];
NSData *imageData = UIImageJPEGRepresentation(img, 0.1);
NSDictionary *parameters = @{@"你们需要的参数": XXXXXXX};
AFHTTPRequestOperation *op = [manager POST:currentUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    
    [formData appendPartWithFileData:imageData name:paramNameForImage fileName:@"photo.jpg" mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@ ***** %@", operation.responseString, error);
}];
[op start];

问题的原因是你走的是GET请求，因为GET请求参数长度是有限制的，例如apache默认是2MB（不知道记错没有），所以如果你图片超过了这个大小，就失败了，你可以把请求改成POST试试。
