post 上的无效索引通过 ASync NSURLConnection

Question

Im posting 数据从 IOS 到 php 脚本。自从从同步请求更改为异步请求后，我一直无法上传。

好的，我的网络服务器日志中出现以下错误

这是发送 post 请求的代码

- (void)uploadToServer:(NSString *)base64Large thumb:(NSString *)base64Thumb {

    NSString *poststring = @"";

    long currentTime = (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970]);
    NSString *currentTimeString = [NSString stringWithFormat:@"%ld",currentTime];
    NSString *fileName = [currentTimeString stringByAppendingString:@".jpg"];

    NSString *postImageName = @"ImageName=%imagename%&";
    postImageName =[postImageName stringByReplacingOccurrencesOfString:@"%imagename%" withString:fileName];

    poststring = [poststring stringByAppendingString:postImageName];


    NSString *postUserID = @"user_id=%UserID%&";
    postUserID =[postUserID stringByReplacingOccurrencesOfString:@"%UserID%" withString:@"2"];

    poststring = [poststring stringByAppendingString:postUserID];

    NSString *postRequestListID = @"RequestID=%RLID%&";
    postRequestListID =[postRequestListID stringByReplacingOccurrencesOfString:@"%RLID%" withString:self.golbalRequestListID];

    poststring = [poststring stringByAppendingString:postRequestListID];

    NSString *postBase64 = @"base64=%B64%&";
    postBase64 =[postBase64 stringByReplacingOccurrencesOfString:@"%B64%" withString:base64Large];
    postBase64 = [postBase64 stringByReplacingOccurrencesOfString:@"+" withString:@"%2B"];

    poststring = [poststring stringByAppendingString:postBase64];

    NSString *postBase64thumb = @"base64_thumb=%B64T%&";
    postBase64thumb =[postBase64thumb stringByReplacingOccurrencesOfString:@"%B64T%" withString:base64Thumb];
    postBase64thumb = [postBase64thumb stringByReplacingOccurrencesOfString:@"+" withString:@"%2B"];

    poststring = [poststring stringByAppendingString:postBase64thumb];


    //create the request

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"iphone2/UploadImage.php"]];

    //Specify that it will be a post request
    request.HTTPMethod = @"POST";

        //This is how we set header fields
    [request setValue:@"application/xml: charset=utf-8" forHTTPHeaderField:@"Content-Type"];

    //convert your data and set your requests httpbody property
    NSData *requestBodyData = [poststring dataUsingEncoding:NSUTF8StringEncoding];
    request.HTTPBody = requestBodyData;


    //create url connection and fire request
    NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];




}

post 请求包含一些数据库条目和 2 张 base64 图像（1 张全尺寸图像约 5-7mb 和缩略图版本 (1-2mb)）

正如我之前所说，使用 Sync 方法时效果很好。

我在 xcode 中没有收到任何错误，当我监视 didSendBodyData 方法时，我可以看到应用正在发送数据。

我认为这可能是 post 请求的问题，但是我找不到检查它是否有效的方法。我还认为我发送的数据量可能有问题，所以我将 post 限制增加到 20MB

老实说，我想不出还有什么问题。

Answer 1

原来是header字段的值有问题

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

影响取自以下post
