AFNetworking文件上传适用于我的PHP脚本，但不适用于jsp脚本

Question

我正在编写一个iPhone应用程序，它将一些信息（一些文本和图像）发送到服务器脚本。

使用我的php脚本一切正常，但是我的客户的jsp脚本（将收到的信息发送到电子邮件地址的电子邮件）没有任何作用...（我知道因为我应该收到自动回复电子邮件，这不会'发生）。

我无法访问我的客户的脚本，因为他们是一个大客户和“一些bla bla安全问题......” 该脚本与在线Web表单一起正常工作，并且在iOS 4.3上与ASIHTTPRequest一起运行良好（我正在迁移到AFNetworking，因为iOS 5 ASIHTTPRequest不起作用）

任何帮助都非常感谢!!!

这是我的代码...请注意我的代码总是到达NSLog（@“成功”），但我没有收到任何自动回复电子邮件，所以它不能正常工作!!

AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://my.client.server.com"]];


    NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
    [parameters setObject:[fieldName text] forKey:@"field01_nome"];
    [parameters setObject:[fieldSurname text] forKey:@"field02_cognome"];



    NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"/Contents/mail/sendToForm.jsp" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
        [formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];
    }];


    AFHTTPRequestOperation *operation = [AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest success:^(id object) {
        NSLog(@"Success");

    } failure:^(NSHTTPURLResponse *response, NSError *error) {
        NSLog(@"Fail");

    }];


    [operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
        NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);

    }];

    queue = [[[NSOperationQueue alloc] init] autorelease];
    [queue addOperation:operation];

非常感谢!!

编辑：正如JosephH所建议的那样，我添加了捕获的请求：

Answer 1

ASIHTTPRequest在iOS 5.0上运行良好;使用ASIHTTPRequest的100个应用程序在iOS 5上没有任何问题。

也就是说，从长远来看，转向AFNetworking可能是有道理的。

这些“它在浏览器中工作，但没有”类型问题很难通过代码检查解决 - 最简单的解决方法是安装像charlesproxy这样的工具。

安装完成后，开始捕获，然后在浏览器中执行请求，验证它是否成功，然后从iOS模拟器执行。然后将浏览器的请求与AFNetworking的请求进行比较，看看您可以发现哪些差异。

如果您无法弄明白，请编辑您的问题以包含两个捕获的请求，我相信有人能够发现它。

Answer 2

AFNetworking和multipart / form-data也存在问题。解决了。当AFNetworking为multipart / form-data生成HTTP主体时，它会将\ r \ n sumbols放在beginig上。您的AFNetworking机构与其他机构之间的区别 - 在开始时是\ r \ n。尝试删除它。我修改了一些AFHTTPClient.m方法，将它们从body的开头删除：

static inline NSString * AFMultipartFormEncapsulationBoundary() {
    return [NSString stringWithFormat:@"%@--%@%@", @""/*kAFMultipartFormLineDelimiter*/, kAFMultipartFormBoundary, kAFMultipartFormLineDelimiter];

}

和

- (void)appendPartWithHeaders:(NSDictionary *)headers body:(NSData *)body {
    [self appendString:AFMultipartFormEncapsulationBoundary()];

    for (NSString *field in [headers allKeys]) {
        [self appendString:[NSString stringWithFormat:@"%@: %@%@", field, [headers valueForKey:field], kAFMultipartFormLineDelimiter]];
    }

    [self appendString:kAFMultipartFormLineDelimiter];
    [self appendData:body];
    [self appendString:kAFMultipartFormLineDelimiter];

}

它对我有用
