服务器看不到“token”和“name+_time”的部分内容

我的代码

NSArray *keysParams = [NSArray arrayWithObjects:@"time",nil];
NSArray *valuesParams = [NSArray arrayWithObjects:time, nil];
NSDictionary *dictParams = [NSDictionary dictionaryWithObjects:valuesParams       forKeys:keysParams];

NSError *writeError = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictParams options:NSJSONWritingPrettyPrinted error:&writeError];


NSData *imageData = UIImageJPEGRepresentation(getImage1, 0.8);
NSString *boundary = @"&&3rewfwefwfewfhufrbewfuweriwefr";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];

NSMutableData *body = [NSMutableData data];

//this appends the image
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"photo.jpg\"\r\n",fileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
//json
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@_time\" \r\n",fileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:jsonData];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//token
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"token\" \r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];

请求正文

imagename(file)
/imagename_time/ - part name
{
time:100
}
/token/ - part name
"string"

我在某个地方有一个错误，但我找不到它。我第一次写多部分帖子。谢谢！

我找到了解决方案。我在错误的“边界”中失败了

工作代码：

//  image
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"photo.jpg\"\r\n",fileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

//  json
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@_time\" \r\n\r\n",fileName"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@", jsonString] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

//  token
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"token\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[token dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

// close form
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];


// setting the body of the post to the reqeust
[request setHTTPBody:body];

谢谢你对我的问题的回答=）
