Question

我正在使用AFNetworking lib 2.2.2版，我想使用POST请求将图像上传到我的服务器。在WiFi中，一切都像魅力一样。服务器返回JSON响应以及HTTP 200响应代码，因此不存在服务器端问题。

如果我在3G中使用POST请求，我总是会遇到“超时”异常，我不知道为什么。

这是我的代码

NSMutableDictionary * params = [[NSMutableDictionary alloc] init];
if(![self isTextEmpty]) {
    [params setValue:textView.text forKey:@"t"];
}

[httpOperationManager POST:@"http://......." parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    if(imageData != nil) {
        [formData appendPartWithFileData:imageData name:@"p" fileName:@"filename" mimeType:@"image/jpg"];
    }
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Done!!!");

    [hud hide:YES];

    [self.delegate updateData];
    [self dismissViewControllerAnimated:YES completion:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", [error localizedDescription]);
    [[[UIAlertView alloc] initWithTitle:@"Error sending post!" message:@"Error" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];

    [hud hide:YES];
}];

如您所见，代码非常简单。我还使用了过程块的变体。使用进度块，我看到文件已完全上传，但该方法始终返回“超时”异常。

我要上传的文件非常小，目前我正在使用200kb文件进行测试，但我也测试了较小的文件没有成功。

我希望你能帮助我！ Thx提前！

这对我有用。

将数据添加到要发送的字典中。

 [registerInputDict setValue:self.fileIdString
                         forKey:@"profileImageId"];

将字典发送到AFNetwork类。

[super postRequestDataWithLoginURL:@"api/user.json" andRequestName:USER_REGISTER andPostData:userDict];


- (AFHTTPRequestOperation *)postRequestDataWithLoginURL:(NSString *)url andRequestName:(NSString *)requestName
                                        andPostData:(NSDictionary*)postData {
[self showProgressIndicator];

AFHTTPClient *afHTTPClient = [AFHTTPClient clientWithBaseURL:BASEURL];

[afHTTPClient setParameterEncoding:AFJSONParameterEncoding];


DebugLog(@"Current Language %@ ",[UserDefaultUtils retriveObjectForKey:LANGUAGE]);
if ([UserDefaultUtils retriveObjectForKey:LANGUAGE]) {

    [afHTTPClient setDefaultHeader:@"x-language-code" value:[UserDefaultUtils retriveObjectForKey:LANGUAGE]];

}
NSMutableURLRequest *request = [afHTTPClient requestWithMethod:@"POST" path:url parameters:postData];


AFHTTPRequestOperation *operation = [afHTTPClient HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) {


    [self successWithRequest:operation withRespose:responseObject withRequestName:requestName];

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    [self failedWithRequest:operation witherror:error withRequestName:requestName];

}];

[afHTTPClient enqueueHTTPRequestOperation:operation];

return operation;
}

成功与失败的反应方法。

- (void)failedWithRequest:(AFHTTPRequestOperation *)operation witherror:(NSError *)error withRequestName:(NSString *)requestName {

id  jsonObject = [operation.responseString objectFromJSONString];

DebugLog(@"registration failed:%@",[error description]);

if ([requestName isEqualToString:UPLOAD_PHOTO]) {

    if  ([self.loginProxyDelegate respondsToSelector:@selector(imageUploadFailed:)]) {

        [self.loginProxyDelegate imageUploadFailed:[jsonObject objectForKey:@"messages"]];
    }

}

}


- (void)successWithRequest:(AFHTTPRequestOperation *)operation withRespose:(id)responseObject withRequestName:(NSString *)requestName {

id  jsonObject = [operation.responseString objectFromJSONString];

if ([requestName isEqualToString:UPLOAD_PHOTO]) {

    [self handleResponseForGetUploadPhoto:jsonObject];

}

}

AFNetworking POST请求无法在3G中运行
